COINBASE GLOBAL, INC. INVESTING RISK. As of the date of this prospectus, Coinbase Global, Inc. faces risks associated with companies in the Financial Services industry group, as well as those inherent in the “crypto assets ecosystem.” The technologies relating to the crypto assets ecosystem are rapidly evolving, and the associated risks may not fully emerge until the technology is widely used. Companies utilize cryptography to optimize their business operations, whether by integrating such technology into their core business or by operating business lines that leverage the technology. Cryptography refers to a set of techniques designed to allow for secure communication in the presence of adversarial threats. Blockchain is a well-known example of a technology that relies on cryptography. A blockchain is comprised of immutable, digitally recorded data organized into packages called “blocks,” which are stored in a linear “chain.” Each block in the chain contains data (e.g., a transaction) that is cryptographically connected to the previous-block in the chain, ensuring all data in the overall “blockchain” remains unchanged and untampered. The cryptographic keys necessary to transact crypto assets may be subject to theft, loss, or destruction, which could adversely affect a company’s business or operations if it were dependent on such an asset. The emergence of competing platforms and technologies may shift consumers or investors towards alternatives to crypto assets. There continue to be regulatory risks associated with crypto assets, as the regulatory landscape continues to shift, and future regulatory developments could affect the viability and expansion of crypto asset technologies. To the extent regulatory action is brought against the Coinbase Global, Inc., the value of the Fund’s holdings in the company could decrease significantly. Companies operating in the crypto assets ecosystem may operate across many national boundaries and regulatory jurisdictions, exposing them to wide-ranging and inconsistent regulation. Companies operating in the crypto assets ecosystem that rely on third-party products may be subject to technical defects or vulnerabilities beyond a company’s control. The absence of standardized exchanges for some crypto assets, like a stock market, may result in reduced liquidity for such assets and greater susceptibility to volatility, fraud or manipulation. In addition, these companies may engage in other lines of business unrelated to the crypto assets ecosystem, which could adversely affect their operating results. Such companies may also engage in activities traditionally associated with the information technology sector and financial sectors. There is no guarantee that companies will be able to develop or capitalize on crypto asset technology applications. Technologies also may never be fully implemented, which could adversely affect an investment in such companies. Companies that use crypto asset technologies may be subject to cybersecurity risk. In addition, certain features of the crypto asset technologies, such as decentralization, open-source protocol and reliance on peer-to-peer connectivity, may increase the risk of fraud or cyber-attack by reducing the likelihood of a coordinated response. A significant disruption of internet connectivity affecting large numbers of users or geographic areas could impede the functionality of crypto asset technologies. Companies that use crypto asset technologies may also be subject to the risks posed by conflicting intellectual property claims, which may reduce confidence in the viability of a crypto asset.

BLOCKCHAIN RISK. Companies that are involved in the crypto asset industry are subject to risks associated with blockchain technology, which could negatively impact their value. Generally, a blockchain is an immutable transaction ledger maintained within a distributed network of peer nodes. The immutability of the blockchain means that once an entry is accepted onto the ledger, it cannot be deleted or changed. A public, permissionless blockchain is open to anyone who wishes to participate, without requiring permission from any central authority. It is decentralized and operates based on a consensus mechanism that ensures trust and security without the need for intermediaries. Public, permissionless blockchains may not have the capacity to execute and settle transactions in a timely and predictable manner and have been prone to periods of congestion and high transaction fees.

 

 

Bitcoin was the first blockchain-based crypto asset, developed to be a decentralized, peer-to-peer electronic cash network, disintermediating centralized monetary systems. Each block contains a list of transactions that, once verified and added to the blockchain through a consensus process known as “proof of work,” becomes irreversible and tamper-evident. On the Bitcoin network, this proof of work process occurs through “mining.” Mining involves miners using sophisticated computer programs to repeatedly solve complex mathematical problems on specialized computer hardware. Miners authenticate and bundle Bitcoin transactions sequentially into files called “blocks.” Because each solved block contains a reference to the previous block, they form a chronological “chain” back to the first Bitcoin transaction. A miner’s proposed block is added to the blockchain once a majority of the nodes on the network confirm the miner’s work. A miner that is successful in adding a block to the blockchain is automatically awarded a fixed amount of Bitcoin for its efforts plus any transaction fees paid by transferors whose transactions are recorded in the block. This reward system is the means by which new Bitcoin enters circulation. However, the open-source nature of blockchain technology makes it vulnerable to being “forked” by users and miners (i.e., creation of a new competing blockchain when a significant portion of the miners adopts updates to the existing blockchain protocol). Additionally, a blockchain may be vulnerable to attacks if a miner or group of miners possesses more than 50% of the blockchain’s “hashing” power, resulting in concentration in the ownership of the blockchain’s native crypto asset. Hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

 

The Bitcoin network and similar blockchain technology allow people to exchange tokens of value, which are recorded on a public transaction ledger. Each token is associated with a set of unique cryptographic “keys,” in the form of a string of numbers and letters, which allow whoever is in possession of the private key to assign that Bitcoin in a transfer that the blockchain network will recognize. One or more private keys control the transfer or “spending” of the token from an associated public address. To use the token, a user or a service provider must have access to keys that identify it for its transactions (similar to an ATM card and its related PIN). Users of blockchain technologies keep their keys in electronic “wallets” that can be maintained on their computers, mobile phones, specialized hardware wallets, or wallets provided by online custodians. To the extent that the private keys securing crypto assets, such as Bitcoin, are lost or stolen, the native crypto assets of these blockchains can be irrevocably lost or stolen.

 

While some blockchains, such as Bitcoin, allow for the exchange of a token of value, other blockchains are designed to support different uses. For example, some blockchains allow users to write and implement smart contracts—self-executing contractual agreements with the terms directly written into code—thereby enabling automated and conditional transactions. However, the code of any smart contracts running on the blockchain may contain flaws that can be exploited by attackers. Crypto assets can be used to pay for goods and services, although they are not currently widely accepted for such purposes, or they can be converted to fiat currencies, such as the U.S. dollar, at rates determined on digital asset trading platforms or in individual end-user-to-end-user transactions under a barter system. Blockchain technology has since evolved to allow for greater programmability, resulting in a wide array of use cases, including smart contracts, without sacrificing the blockchain’s core tenets: decentralization, security, and scalability.

 

 

REX COIN Growth & Income ETF | CRYPTO ASSET MARKET AND VOLATILITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CRYPTO ASSET MARKET AND VOLATILITY RISK. The prices of crypto assets have historically been highly volatile and may significantly impact companies such as the Underlying Security that are involved in the crypto asset industry. The value of such assets has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The value of a Fund’s investments in instruments that provide exposure to the Underlying Security – and therefore the value of an investment in a Fund – could decline significantly and without warning. If you are not prepared to accept significant and unexpected changes in the value of a Fund, you should not invest in the Fund.

 

REX COIN Growth & Income ETF | UNDERLYING SECURITY PERFORMANCE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX COIN Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

 

REX COIN Growth & Income ETF | SINGLE ISSUER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

 

REX COIN Growth & Income ETF | ACTIVE MANAGEMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

 

 

REX COIN Growth & Income ETF | AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX COIN Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

REX COIN Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX COIN Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX COIN Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX COIN Growth & Income ETF | FINANCIAL SERVICES INDUSTRY GROUP RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FINANCIAL SERVICES INDUSTRY GROUP RISK. Companies in the Financial Services industry group are subject to extensive governmental regulation and intervention, which may adversely affect their activities, pricing, capital and liquidity requirements, and potentially their size. Frequent changes in regulation can have significant unintended adverse consequences for these companies. Increased risk-taking by companies in this industry group may heighten overall risk in the U.S. and globally. The impact of changes in capital requirements or regulation on individual companies or the industry as a whole is unpredictable. Certain risks may affect the value of investments in companies in the Financial Services industry group more severely than those outside this industry. Significant exposure to the same borrowers and counterparties by companies within this industry group may can also lead to negative impacts if a borrower or counterparty defaults. Financial Services companies may also be adversely affected by interest rate increases, loan losses, decreased money availability or asset valuations, credit rating downgrades, adverse public perception, and related market conditions. The industry is a target for cyberattacks, with cybersecurity incidents and technology failures causing significant losses. These factors may negatively impact the Fund. Additionally, the extent to which the Fund may invest in companies engaging in securities-related activities or banking is limited by applicable law.

 

REX COIN Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

 

 

REX COIN Growth & Income ETF | COSTS OF BUYING AND SELLING FUND SHARES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX COIN Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX COIN Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

 

REX COIN Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

REX COIN Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX COIN Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

 

REX COIN Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX COIN Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

REX COIN Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX COIN Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

 

REX COIN Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

 

REX COIN Growth & Income ETF | DIVIDEND RISK [Member]

DIVIDEND RISK. There is no guarantee that the issuers of the Fund’s portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

 

REX COIN Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

REX COIN Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Risk [Text Block]

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

REX COIN Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX COIN Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX COIN Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX COIN Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

REX COIN Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

 

REX COIN Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX COIN Growth & Income ETF | MARKET RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

 

REX COIN Growth & Income ETF | OPERATIONAL RISK [Member]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

 

REX COIN Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX COIN Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

 

REX COIN Growth & Income ETF | REBALANCING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

 

REX COIN Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

Prospectus [Line Items]  
Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX COIN Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX CRWV Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the common stock of the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

 

REX CRWV Growth & Income ETF | AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK [Member]

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX CRWV Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

 

REX CRWV Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX CRWV Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX CRWV Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX CRWV Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX CRWV Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX CRWV Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX CRWV Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

 

REX CRWV Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX CRWV Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

REX CRWV Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX CRWV Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

 

REX CRWV Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX CRWV Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX CRWV Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

REX CRWV Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

 

REX CRWV Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX CRWV Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

 

REX CRWV Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX CRWV Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX CRWV Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX CRWV Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

 

REX CRWV Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX CRWV Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX CRWV Growth & Income ETF | MARKET RISK [Member]

Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX CRWV Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX CRWV Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX CRWV Growth & Income ETF | SPECIAL TAX RISK [Member]

Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

 

REX CRWV Growth & Income ETF | TRADING ISSUES RISK [Member]

Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

 

REX CRWV Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

COREWEAVE, INC. INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the Software & Services industry group, CoreWeave, Inc. faces risks related to: supply or manufacturing delays; increased material or labor costs or shortages; reduced demand for its products, product liability claims; the ability to attract, hire and retain key employees or qualified personnel; environmental risk; terrorism risk; and risk of natural disasters. CoreWeave, Inc. has transitioned from its limited operating history phase and is now a rapidly scaling public entity with a significant revenue backlog. As a result, the company faces new pressures regarding profitability and intense capital expenditure requirements. CoreWeave, Inc. continues to face risks associated with dependence on a small number of large customers and concentration of revenues; the capital-intensive nature of its business and the need for significant ongoing investment in infrastructure; reliance on a limited number of suppliers for GPUs, networking equipment, and other critical components; constraints related to data center capacity, power availability, and energy costs; intense competition in the cloud infrastructure market; risks associated with rapid technological change in artificial intelligence and high-performance computing; system outages, service disruptions, or cybersecurity incidents; reliance on third-party data centers and service providers; regulatory, environmental, and energy-related requirements; and general macroeconomic conditions that may affect customer demand and financing availability. Additionally, the trading price of CoreWeave, Inc. common stock has historically been, and may continue to be, volatile. A large proportion of CoreWeave, Inc.’s common stock has been historically, and may in the future be, traded by short sellers which may put pressure on the supply and demand for its common stock, further influencing volatility in its market price. CoreWeave, Inc. is a highly dynamic company, and its operations, including its products and services, may change.

ARTIFICIAL INTELLIGENCE COMPANY RISK. Companies involved in, or exposed to, artificial intelligence related businesses may have limited product lines, markets, financial resources or personnel. These companies face intense competition and potentially rapid product obsolescence, and many depend significantly on retaining and growing the consumer base of their respective products and services. Many of these companies are also reliant on the end user demand of products and services in various industries that may in part utilize robotics and artificial intelligence.

SOFTWARE & SERVICES INDUSTRY GROUP RISK. Companies in the Software & Services industry group can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and the availability and price of components. The market for their products is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. Success in this industry group is largely dependent on the timely and successful introduction of new products and the ability to service such products. Unexpected changes in technology or market demand can have a material adverse effect on the operating results of companies in the Software & Services industry group. Many companies in this industry group rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by these companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX HOOD Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the common stock of the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX HOOD Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

 

REX HOOD Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX HOOD Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX HOOD Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX HOOD Growth & Income ETF | FINANCIAL SERVICES INDUSTRY GROUP RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FINANCIAL SERVICES INDUSTRY GROUP RISK. Companies in the Financial Services industry group are subject to extensive governmental regulation and intervention, which may adversely affect their activities, pricing, capital and liquidity requirements, and potentially their size. Frequent changes in regulation can have significant unintended adverse consequences for these companies. Increased risk-taking by companies in this industry group may heighten overall risk in the U.S. and globally. The impact of changes in capital requirements or regulation on individual companies or the industry as a whole is unpredictable. Certain risks may affect the value of investments in companies in the Financial Services industry group more severely than those outside this industry. Significant exposure to the same borrowers and counterparties by companies within this industry group may can also lead to negative impacts if a borrower or counterparty defaults. Financial Services companies may also be adversely affected by interest rate increases, loan losses, decreased money availability or asset valuations, credit rating downgrades, adverse public perception, and related market conditions. The industry is a target for cyberattacks, with cybersecurity incidents and technology failures causing significant losses. These factors may negatively impact the Fund. Additionally, the extent to which the Fund may invest in companies engaging in securities-related activities or banking is limited by applicable law.

 

 

REX HOOD Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX HOOD Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX HOOD Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX HOOD Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

 

REX HOOD Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX HOOD Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

REX HOOD Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX HOOD Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

 

REX HOOD Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX HOOD Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX HOOD Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

DIVIDEND RISK. There is no guarantee that the issuers of the Fund’s portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

 

 

REX HOOD Growth & Income ETF | EQUITY SECURITIES RISK [Member]

Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

REX HOOD Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Risk [Text Block]

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

 

REX HOOD Growth & Income ETF | INDIRECT INVESTMENT RISK [Member]

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX HOOD Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

 

REX HOOD Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX HOOD Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

 

REX HOOD Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX HOOD Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

 

REX HOOD Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX HOOD Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX HOOD Growth & Income ETF | MARKET RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX HOOD Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX HOOD Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

 

 

REX HOOD Growth & Income ETF | REBALANCING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX HOOD Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

 

REX HOOD Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

Prospectus [Line Items]  
Risk [Text Block]

ROBINHOOD MARKETS, INC. INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the Financial Services industry group, Robinhood Markets, Inc. faces risks related to competition with traditional brokerages and fintech rivals, which may lead to pricing pressures, customer turnover and the need for costly product innovation. The company’s innovation efforts are increasingly focused on expanding its product offerings and entering new markets, such as its Gold Card and UK expansion, to strengthen customer relationships and diversify revenue sources. Robinhood remains exposed to volatility in options and crypto trading; while the SEC dropped its investigation into Robinhood Crypto in February 2025, the company continues to be sensitive to digital asset market fluctuations. Robinhood Markets, Inc.’s customer base is primarily retail investors, who may trade less frequently during economic downturns or bearish markets, and a decline in speculative trading activity could reduce revenue. The company has diversified its revenue streams, with growth in subscriptions, net interest income, and credit card services, making it less dependent on transaction-based payment for order flow (PFOF) than in previous years. However, PFOF remains a risk, as regulatory criticism or restrictions could still impact the business model. The company also faces risks associated with margin lending, interest on customer cash balances and interest rates. Trading outages and technical failures experienced by Robinhood Markets, Inc., particularly during periods of high market volatility, have resulted in customer complaints, regulatory fines, and lawsuits, posing a significant operational risk. Exposure to hacking attempts, account breaches, and identity theft risks, and a significant security incident could harm user trust and lead to regulatory consequences. Robinhood Markets, Inc.’s operates in the highly regulated industry, subject to oversight from the SEC, FINRA and other regulatory bodies. Changes in financial regulations could increase compliance costs, limit business practices, or lead to operational restrictions. The company continues to face class-action lawsuits, regulatory fines, and customer complaints. Trading through third-party market makers and reliance on payment for order flow add further risk. Any of these factors could materially and adversely affect Robinhood Markets, Inc.’s business, financial condition, and results of operations.

SMALL AND/OR MID CAPITALIZATION COMPANIES RISK. Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large capitalization companies.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX LLY Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the common stock of the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX LLY Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

REX LLY Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX LLY Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX LLY Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX LLY Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

 

REX LLY Growth & Income ETF | COSTS OF BUYING AND SELLING FUND SHARES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX LLY Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX LLY Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX LLY Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

 

REX LLY Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX LLY Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

REX LLY Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX LLY Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

 

REX LLY Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX LLY Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX LLY Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

DIVIDEND RISK. There is no guarantee that the issuers of the Fund’s portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

 

REX LLY Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

 

REX LLY Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

 

REX LLY Growth & Income ETF | INDIRECT INVESTMENT RISK [Member]  
Prospectus [Line Items]

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX LLY Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

 

REX LLY Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX LLY Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX LLY Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX LLY Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

 

REX LLY Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX LLY Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX LLY Growth & Income ETF | MARKET RISK [Member]

Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX LLY Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX LLY Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX LLY Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX LLY Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

ELI LILLY AND COMPANY INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the Pharmaceuticals, Biotechnology & Life Sciences industry group, Eli Lilly and Company faces risks related to: the costly and unpredictable nature of research and development for its products; maintaining intellectual property rights; fierce competition from peers and lower-cost generic and biosimilar manufacturers; increasing government-imposed price controls and public and private sector restrictions on drug pricing, reimbursement, and access; potential concerns regarding the safety or effectiveness of products; a limited product portfolio and reliance on a consolidated supply chain; cyber security breaches and data protection compliance risks; manufacturing, quality control, or supply chain challenges that could lead to product shortages; dependence on third-party partnerships and outsourcing; integration of artificial intelligence and other new technologies; complexities of international business operations; and the impact of government regulations and legal actions. Additionally, Eli Lilly and Company is involved in litigation and investigations concerning its products, pricing strategies, commercialization practices, and other business operations, which could negatively impact its business. The company is self-insured for these matters. Eli Lilly and Company must also navigate complex and evolving tax laws, which may lead to additional liabilities and influence its operational results. Regulatory compliance issues could also be detrimental to Eli Lilly and Company.

Risk [Text Block]

PHARMACEUTICALS, BIOTECHNOLOGY & LIFE SCIENCES INDUSTRY GROUP RISK. Companies in the Pharmaceuticals, Biotechnology & Life Sciences industry group face significant risks, including costly and highly uncertain research and development efforts. These companies may not succeed in developing, licensing or acquiring commercially successful products sufficient in number or value to replace revenues from products that have lost or will lose intellectual property protection or are displaced by competing products or therapies. These companies are subject to intense competition from multinational pharmaceutical companies, biotechnology companies and lower-cost generic and biosimilar manufacturers, which could have a material adverse effect on their business. The industry group is heavily regulated, with government approval of products and services, government regulation and reimbursement rates playing a critical role. The process of obtaining and maintaining regulatory approvals is long, costly and uncertain, and changes in governmental policies or the need for regulatory approvals may have a material adverse effect on these companies’ operations. Their products may not be accepted by patients or providers, and unanticipated problems often arise in connection with the development, manufacturing, marketing and distribution of new products, many of which are ultimately unsuccessful. Companies in the Pharmaceuticals, Biotechnology & Life Sciences industry group are subject to increasing government price controls and other public and private restrictions on pricing, reimbursement and access for their drugs, which could have a material adverse effect on their results of operations, reputation or business. These companies may not be able to obtain adequate pricing and reimbursement levels for any marketed products, impeding their ability to generate a profit. Pharmaceutical products can develop safety or efficacy concerns, which could have a material adverse effect on their revenues, income, and reputation. Companies may also face product liability and other actions should their products be less safe or efficacious than believed, should they be deemed to have engaged in misleading practices, or should a person that received their product otherwise experience harm or injury.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

 

REX MSTR Growth & Income ETF | BLOCKCHAIN RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

BLOCKCHAIN RISK. Companies that are involved in the crypto asset industry are subject to risks associated with blockchain technology, which could negatively impact their value. Generally, a blockchain is an immutable transaction ledger maintained within a distributed network of peer nodes. The immutability of the blockchain means that once an entry is accepted onto the ledger, it cannot be deleted or changed. A public, permissionless blockchain is open to anyone who wishes to participate, without requiring permission from any central authority. It is decentralized and operates based on a consensus mechanism that ensures trust and security without the need for intermediaries. Public, permissionless blockchains may not have the capacity to execute and settle transactions in a timely and predictable manner and have been prone to periods of congestion and high transaction fees.

 

 

Bitcoin was the first blockchain-based crypto asset, developed to be a decentralized, peer-to-peer electronic cash network, disintermediating centralized monetary systems. Each block contains a list of transactions that, once verified and added to the blockchain through a consensus process known as “proof of work,” becomes irreversible and tamper-evident. On the Bitcoin network, this proof of work process occurs through “mining.” Mining involves miners using sophisticated computer programs to repeatedly solve complex mathematical problems on specialized computer hardware. Miners authenticate and bundle Bitcoin transactions sequentially into files called “blocks.” Because each solved block contains a reference to the previous block, they form a chronological “chain” back to the first Bitcoin transaction. A miner’s proposed block is added to the blockchain once a majority of the nodes on the network confirm the miner’s work. A miner that is successful in adding a block to the blockchain is automatically awarded a fixed amount of Bitcoin for its efforts plus any transaction fees paid by transferors whose transactions are recorded in the block. This reward system is the means by which new Bitcoin enters circulation. However, the open-source nature of blockchain technology makes it vulnerable to being “forked” by users and miners (i.e., creation of a new competing blockchain when a significant portion of the miners adopts updates to the existing blockchain protocol). Additionally, a blockchain may be vulnerable to attacks if a miner or group of miners possesses more than 50% of the blockchain’s “hashing” power, resulting in concentration in the ownership of the blockchain’s native crypto asset. Hashing power refers to the computational capacity used to validate and secure transactions on the blockchain.

 

The Bitcoin network and similar blockchain technology allow people to exchange tokens of value, which are recorded on a public transaction ledger. Each token is associated with a set of unique cryptographic “keys,” in the form of a string of numbers and letters, which allow whoever is in possession of the private key to assign that Bitcoin in a transfer that the blockchain network will recognize. One or more private keys control the transfer or “spending” of the token from an associated public address. To use the token, a user or a service provider must have access to keys that identify it for its transactions (similar to an ATM card and its related PIN). Users of blockchain technologies keep their keys in electronic “wallets” that can be maintained on their computers, mobile phones, specialized hardware wallets, or wallets provided by online custodians. To the extent that the private keys securing crypto assets, such as Bitcoin, are lost or stolen, the native crypto assets of these blockchains can be irrevocably lost or stolen.

 

While some blockchains, such as Bitcoin, allow for the exchange of a token of value, other blockchains are designed to support different uses. For example, some blockchains allow users to write and implement smart contracts—self-executing contractual agreements with the terms directly written into code—thereby enabling automated and conditional transactions. However, the code of any smart contracts running on the blockchain may contain flaws that can be exploited by attackers. Crypto assets can be used to pay for goods and services, although they are not currently widely accepted for such purposes, or they can be converted to fiat currencies, such as the U.S. dollar, at rates determined on digital asset trading platforms or in individual end-user-to-end-user transactions under a barter system. Blockchain technology has since evolved to allow for greater programmability, resulting in a wide array of use cases, including smart contracts, without sacrificing the blockchain’s core tenets: decentralization, security, and scalability.

Prospectus [Line Items]  
Risk [Text Block]

CRYPTO ASSET MARKET AND VOLATILITY RISK. The prices of crypto assets have historically been highly volatile and may significantly impact companies such as the Underlying Security that are involved in the crypto asset industry. The value of such assets has been, and may continue to be, substantially dependent on speculation, such that trading and investing in these assets generally may not be based on fundamental analysis. The value of a Fund’s investments in instruments that provide exposure to the Underlying Security – and therefore the value of an investment in a Fund – could decline significantly and without warning. If you are not prepared to accept significant and unexpected changes in the value of a Fund, you should not invest in the Fund.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX MSTR Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX MSTR Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

REX MSTR Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX MSTR Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

 

REX MSTR Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX MSTR Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX MSTR Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX MSTR Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

 

REX MSTR Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX MSTR Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

 

REX MSTR Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX MSTR Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

REX MSTR Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX MSTR Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

 

REX MSTR Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

REX MSTR Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

REX MSTR Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

 

REX MSTR Growth & Income ETF | INDIRECT INVESTMENT RISK [Member]

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX MSTR Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

REX MSTR Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX MSTR Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX MSTR Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX MSTR Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

REX MSTR Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX MSTR Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX MSTR Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

 

REX MSTR Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

 

REX MSTR Growth & Income ETF | REBALANCING RISK [Member]

Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX MSTR Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX MSTR Growth & Income ETF | VALUATION RISK [Member]

Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

SOFTWARE & SERVICES INDUSTRY GROUP RISK. Companies in the Software & Services industry group can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and the availability and price of components. The market for their products is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. Success in this industry group is largely dependent on the timely and successful introduction of new products and the ability to service such products. Unexpected changes in technology or market demand can have a material adverse effect on the operating results of companies in the Software & Services industry group. Many companies in this industry group rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by these companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

STRATEGY INC. INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the software industry and information technology sector, Strategy Inc. faces risks related to its bitcoin acquisition strategy, including: the various risks associated with bitcoin; the risks associated with bitcoin being a highly volatile asset; the risk that the company’s historical financial statements do not reflect the potential variability in earnings that the company may experience in the future relating to its bitcoin holdings; the risk that the availability of spot bitcoin exchange-traded products may adversely affect the market price of Strategy Inc.; the risk of enhanced regulatory oversight; concentration risk; liquidity risk; and counterparty risk, particularly with respect to custodians. Strategy Inc. also faces risks related to its enterprise analytics software business strategy, including: risks relating to its dependence on revenue from a single software platform and related services as well as revenue from its installed customer base; the risk that as customers increasingly shift from a product license model to a cloud subscription model, the company could face higher future rates of attrition, and such a shift could continue to affect the timing of revenue recognition or reduce product licenses and product support revenues, which could materially adversely affect the company’s operating results; the risk that if the company is unable to develop and release new software product offerings or enhancements to its existing offerings in a timely and cost-effective manner, the company’s business, operating results, and financial condition could be materially adversely affected; and the risk the company’s software may be susceptible to undetected errors, bugs, or security vulnerabilities, which could cause problems with how the software performs and, in turn, reduce demand for the company’s software, reduce its revenue, and lead to litigation claims against the company.

 

REX MSTR Growth & Income ETF | BITCOIN RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

BITCOIN RISK. Bitcoin is a relatively new innovation and the market for bitcoin is subject to constant change. As Bitcoin continues to develops, there are variety of risks that have arisen and that may arise in the future. For example, public conception and acceptance of bitcoin and the use of bitcoin are constantly evolving. If public sentiment regarding bitcoin were to decline, or the development and use of bitcoin were to decrease, the value of bitcoin could be adversely affected. Bitcoin is also subject to the risk of fraud, theft, manipulation or security failures, including hacking of the Bitcoin blockchain, or other problems may arise that impact the digital asset trading venues on which bitcoin trades. A significant portion of bitcoin is held by a small number of holders sometimes referred to as “whales” that, as a result of their holdings, have significant influence over bitcoin pricing.

 

Bitcoin and the digital asset trading venues on which it trades are largely unregulated and highly fragmented, although the government, under the Trump administration, has made development of the U.S. digital asset infrastructure a priority, including with proposals such as the U.S Digital Asset Market Clarity (“CLARITY”) Act. However, as the laws and regulations covering the digital assets framework continue to develop, risks such as fraud and market manipulation will exist for digital assets. For example, individuals or groups may promote bitcoin to artificially increase the price of bitcoin. Over the past several years, a number of digital asset trading venues have been closed due to fraud, failure or security breaches. As U.S government works to establish the regulatory framework and safeguards around digital assets, risks to investors remain, and investors in bitcoin may have little or no recourse should theft, fraud or manipulation occur, potentially resulting in significant losses. The Underlying Security may also be negatively impacted by regulatory enforcement actions against the digital asset trading venues upon which bitcoin trades. Any actions could significantly reduce the number of venues upon which bitcoin trades and could negatively impact the value of bitcoin held the Underlying Security. In addition, digital asset trading venues, bitcoin miners, and other participants may have significant exposure to other digital assets. Instability in the price, availability or legal or regulatory status of those instruments may adversely impact the operation of the digital asset trading venues and the Bitcoin network. The realization of any of these risks could result in a decline in the acceptance of bitcoin and consequently a reduction in the value of bitcoin and the Underlying Security. To the extent the Underlying Security has exposure to or investments in other digital assets besides bitcoin, such exposure or investments are subject to significant risks, including volatility, regulatory uncertainty, and potential loss of value, which may adversely affect the performance of the Underlying Security.

 

 

The Bitcoin blockchain and its native crypto asset, bitcoin, continue to face challenges to gaining widespread adoption as an alternative payments system, including with respect to transaction processing and finality, variability in transaction fees and volatility in pricing. The social, legal, and regulatory obstacles and uncertainty that Bitcoin blockchain and bitcoin face are risks that continue to raise uncertainty about the long-term outlook of the Bitcoin blockchain as an alternative payment system, which could negatively impact bitcoin pricing. In addition, alternative public blockchains have been developed that compete with the Bitcoin blockchain, which may offer certain advantages, including higher throughput, lower fees, faster settlement and finalization, and the ability to facilitate untraceable and/or privacy-shielded transactions through the use of zero-knowledge cryptography or other means. While Bitcoin holds the highest market capitalization, it is possible that these alternative public blockchains and their native crypto assets may become more successful than the Bitcoin blockchain and bitcoin in gaining adoption as an alternative payments system, which could negatively impact the long-term adoption and price of Bitcoin blockchain and price of bitcoin.

 

Finally, one means by which the ecosystem surrounding the Bitcoin blockchain has attempted to mitigate concerns about the slowness of transaction processing and finality and the variability of transaction fees has been through the development of so-called Layer 2 networks, including the “Lightning Network.” Layer 2 networks are separate blockchains built on top of “Layer 1” blockchains like the Bitcoin blockchain for the purpose of augmenting the throughput of the Layer 1 blockchain, and often, providing lower fees for transaction processing and faster settlement. Layer 2 blockchains introduce certain risks into the Bitcoin ecosystem that should be considered. For instance, Layer 2 blockchains are a relatively new and still developing technology. Technological issues – including hacks, bugs, or failures – could introduce risk or harm confidence in the Bitcoin ecosystem, which could negatively impact the price of bitcoin. In addition, users may choose to settle an increasing share of transactions on Layer 2 blockchains, which could negatively impact the transaction activity on, and the amount of fee revenue generated by, the Bitcoin blockchain itself, which could negatively impact the price of bitcoin. If these or other developments negatively impact the price of bitcoin, this would negatively impact the value of the Underlying Security.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX NVDA Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

 

 

REX NVDA Growth & Income ETF | SINGLE ISSUER RISK [Member]

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

 

REX NVDA Growth & Income ETF | ACTIVE MANAGEMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX NVDA Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

 

REX NVDA Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX NVDA Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX NVDA Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX NVDA Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

 

REX NVDA Growth & Income ETF | COSTS OF BUYING AND SELLING FUND SHARES RISK [Member]  
Prospectus [Line Items]

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX NVDA Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX NVDA Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX NVDA Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

 

REX NVDA Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX NVDA Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

REX NVDA Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX NVDA Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

 

REX NVDA Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX NVDA Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX NVDA Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

REX NVDA Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

REX NVDA Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

 

REX NVDA Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX NVDA Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX NVDA Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

 

REX NVDA Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

REX NVDA Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX NVDA Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX NVDA Growth & Income ETF | MARKET RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

 

REX NVDA Growth & Income ETF | OPERATIONAL RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX NVDA Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX NVDA Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

 

 

REX NVDA Growth & Income ETF | REBALANCING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX NVDA Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

 

REX NVDA Growth & Income ETF | TRADING ISSUES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

Prospectus [Line Items]  
Risk [Text Block]

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

 

REX NVDA Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

NVIDIA CORPORATION INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the semiconductors & semiconductor equipment industry group and information technology sector, Nvidia Corporation faces risks associated with: failure to meet the evolving needs of its large markets – gaming, data center, professional visualization and automotive – and identifying new products, services and technologies; competition; changes in customer demand; supply chain issues; manufacturing delays; potential significant mismatches between supply and demand giving rise to product shortages or excessive inventory; the dependence on third-parties and their technology to manufacture, assemble, test, or package its products which reduces control over product quantity and quality, manufacturing yields, development, enhancement and product delivery schedules; significant product defects; international sales and operations, including adverse economic conditions; impacts from climate change, including water and energy availability; inability to realize the potential benefits from business investments and acquisitions; concentration of revenue from a limited number of partners, distributors and customers; the ability to attract, retain and motivate executives and key employees; system security and data protection breaches, including cyberattacks; business disruptions; the proper function of its business processes and information systems; fluctuations in operating results; increased scrutiny from shareholders and regulators regarding its environmental, social and governance responsibilities could result in increased operating expenses or adversely impact its reputation or ability to attract customers or suppliers; issues related to the responsible use of artificial intelligence (AI); ability to protect its intellectual property; ever changing and increasingly stringent data privacy and security laws and regulations; as well as other regulatory, tax related and legal issues, including the changing regulations regarding AI.

Prospectus [Line Items]  
Risk [Text Block]

SEMICONDUCTORS & SEMICONDUCTOR EQUIPMENT Industry GROUP RISK. Investing in the companies comprising the Semiconductors & Semiconductor Equipment industry group may expose the Fund to specific risks related to companies operating in this industry. Semiconductors & semiconductor equipment companies face intense competition, both domestically and internationally, and such competition may have an adverse effect on profit margins. Semiconductors & semiconductor equipment companies may have limited product lines, markets, financial resources or personnel. Semiconductors & semiconductor equipment companies’ supply chain and operations are dependent on the availability of materials that meet exacting standards and the use of third parties to provide components and services. Semiconductors & semiconductor equipment companies may rely on a limited number of suppliers, or upon suppliers in a single location, for certain materials, equipment or tools. Finding and qualifying alternate or additional suppliers can be a lengthy process that can cause production delays or impose unforeseen costs, and such alternatives may not be available at all. Production can be disrupted by the unavailability of resources, such as water, silicon, electricity, gases and other materials. Suppliers may also increase prices or encounter cybersecurity or other issues that can disrupt production or increase production costs. The products of semiconductors & semiconductor equipment companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Capital equipment expenditures could be substantial, and equipment generally suffers from rapid obsolescence. Companies in the semiconductors & semiconductor equipment industry are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights would adversely affect the profitability of these companies.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX PLTR Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the common stock of the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX PLTR Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

REX PLTR Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX PLTR Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX PLTR Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX PLTR Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX PLTR Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX PLTR Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

REX PLTR Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX PLTR Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

 

REX PLTR Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX PLTR Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

REX PLTR Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

 

REX PLTR Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX PLTR Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

REX PLTR Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

 

REX PLTR Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX PLTR Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

REX PLTR Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

 

REX PLTR Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX PLTR Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX PLTR Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

 

REX PLTR Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX PLTR Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

REX PLTR Growth & Income ETF | MARKET RISK [Member]

Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX PLTR Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX PLTR Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX PLTR Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

SOFTWARE & SERVICES INDUSTRY GROUP RISK. Companies in the Software & Services industry group can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and the availability and price of components. The market for their products is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. Success in this industry group is largely dependent on the timely and successful introduction of new products and the ability to service such products. Unexpected changes in technology or market demand can have a material adverse effect on the operating results of companies in the Software & Services industry group. Many companies in this industry group rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by these companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

PALANTIR TECHNOLOGIES INC. INVESTING RISK. As of the date of this prospectus, in addition to the risks associated with companies in the Software & Services industry group, Palantir Technologies Inc. faces risks related to: Palantir Technologies Inc.’s revenue from government contracts, which are susceptible to termination, non-renewal, or funding reductions due to budgetary constraints or political decisions; shifts in government priorities or the loss of key contracts, which could negatively impact its business operations; the highly competitive and rapidly evolving industry in which Palantir Technologies Inc. operates, including competition from established technology firms and emerging startups offering innovative solutions; the development, deployment and adoption of new technologies and artificial intelligence capabilities; failure to maintain competitive advantage, which could lead to diminished market share and profitability; the company’s operations, especially its engagements with government and defense agencies, subject it to regulatory scrutiny and geopolitical risks; dependence on third-party products and services; changes in data privacy laws, export controls, or international relations affecting its ability to conduct business effectively; delivery of secure, reliable, and advanced software solutions; cyber security vulnerabilities, system outages, or technological obsolescence resulting in damage to its reputation and client trust, resulting in financial losses; intellectual property protection; reputational and ethical concerns; and the limited number of clients from which Palantir Technologies Inc. derives a substantial portion of its revenue, creating risk that makes the company vulnerable to shifts in spending patterns or contract renewals from a small group of customers.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX TSLA Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

SINGLE ISSUER RISK. Issuer-specific attributes may cause an investment in the Fund to be more volatile than a traditional pooled investment which diversifies risk or the market generally. The value of the Fund, which focuses on an individual security (i.e., the Underlying Security), may be more volatile than a traditional pooled investment or the market as a whole and may perform differently from the value of a traditional pooled investment or the market as a whole.

 

REX TSLA Growth & Income ETF | ACTIVE MANAGEMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. In managing the Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses, including through the use of technology, automated processes, algorithms, or other management systems, that may not operate as intended or produce the desired result. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

AUTHORIZED PARTICIPANTS, MARKET MAKERS, AND LIQUIDITY PROVIDERS LIMITATION RISK. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX TSLA Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

 

REX TSLA Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX TSLA Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX TSLA Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX TSLA Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

 

REX TSLA Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

REX TSLA Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX TSLA Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

 

REX TSLA Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX TSLA Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

REX TSLA Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

 

REX TSLA Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

REX TSLA Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

REX TSLA Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX TSLA Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

REX TSLA Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

REX TSLA Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

Risk [Text Block]

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX TSLA Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

REX TSLA Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

REX TSLA Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

 

REX TSLA Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX TSLA Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

REX TSLA Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

REX TSLA Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

 

 

REX TSLA Growth & Income ETF | MARKET RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

Prospectus [Line Items]  
Risk [Text Block]

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

 

REX TSLA Growth & Income ETF | OPERATIONAL RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund, Adviser, and Sub-Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

REX TSLA Growth & Income ETF | PREMIUM/DISCOUNT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

 

REX TSLA Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

 

REX TSLA Growth & Income ETF | REBALANCING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying Security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX TSLA Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

Risk [Text Block]

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX TSLA Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

As of the date of this prospectus, in addition to the risks associated with companies operating in the automotives industry and consumer discretionary sector, Tesla, Inc. faces risks associated with: potential delays in launching and scaling production of products and features; suppliers may be unable to deliver components according to schedule or at acceptable prices or volumes; projected construction timelines may be hard to predict; growing global sales, delivery and installation capabilities as well as increasing the global vehicle charging network may be difficult; maintaining and growing access to battery cells may be difficult; the future demand for electric vehicles is unpredictable; competition is increasing from a growing list of established and new competitors; issues with manufacturing lithium-ion cells or other components for its electric vehicles; the ability to maintain and expand international operations; products or features may contain defects or take longer than expected to be fully functional; product liability claims; maintaining public credibility and confidence for the long term, including the management of recalls and warranties; the potential for difficulties with growing or maintaining the various offered financing programs; managing ongoing obligations with the Research Foundation for the State University of New York relating to the Gigafactory New York; the ability to attract, hire and retain key employees or qualified personnel; being highly dependent on the services of Elon Musk, its Chief Executive Officer; system security and data protection breaches, including cyberattacks; the potential for union activities to cause disruptions; as well as other operational, regulatory, tax related and legal issues. Additionally, communications by Mr. Musk to the public may significantly impact the trading price of Tesla, Inc.’s common stock. Any actual or anticipated large transactions in Tesla, Inc.’s common stock by Mr. Musk may cause the stock price to decline. The trading price of Tesla, Inc.’s common stock historically has been and is likely to continue to be volatile. Tesla, Inc. has held digital assets, as part of its corporate treasury operations. The market value of digital assets is highly volatile and may be subject to significant price fluctuations, which could materially adversely affect the Underlying Security’s financial condition, results of operations, liquidity, or stock price.

 

REX TSLA Growth & Income ETF | AUTOMOBILES & COMPONENTS INDUSTRY GROUP RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

AUTOMOBILES & Components Industry group RISK. Investing in companies within the automobiles & components industry group exposes the Fund to specific risks related to the unique characteristics and challenges of this industry. The automobiles & components industry group is highly cyclical and sensitive to economic downturns, which can lead to reduced consumer spending on new vehicles. Economic conditions, interest rates, and consumer confidence significantly impact demand, and a slowdown in the economy may adversely affect revenue and profit margins of automotive companies, which could negatively impact the Fund’s performance. Governmental policies affecting the automobiles & components industry group, such as taxes, tariffs, duties, subsidies, and import and export restrictions on automotive products can influence industry profitability. Companies in this industry also face substantial regulatory requirements, including emissions standards and safety regulations, which can drive up production costs and affect profitability. Additionally, rapid technological advancements, such as the shift toward electric vehicles and autonomous driving, require significant capital investment and may disrupt traditional business models. Companies that fail to innovate or keep pace with technological advancements may face declining market share or increased costs, affecting their financial health and stability. The success of electric and autonomous vehicle companies is influenced by government policies, such as subsidies, tax incentives, emissions regulations, and autonomous driving laws. Companies developing or deploying autonomous driving technologies are subject to a range of risks, including technological failures, cybersecurity breaches, and system malfunctions. Consumer adoption of electric and autonomous vehicles depends on factors such as vehicle affordability, charging infrastructure availability, range anxiety, and consumer trust in autonomous driving technology. The automobiles & components industry group is also susceptible to supply chain disruptions, particularly for essential components like semiconductors, batteries, and raw materials. Shortages or delays can hinder production, elevate costs, and lead to revenue loss. These supply chain challenges, coupled with the impact of environmental, social, and governance (ESG) concerns, can result in volatile stock performance within the sector, leading to potential losses for the Fund and its shareholders.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.

UNDERLYING SECURITY PERFORMANCE RISK. The Underlying Security may fail to meet its publicly announced guidelines or other expectations about its business, which could cause the price of the Underlying Security to decline. The Underlying Security may provide guidance regarding its expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and the guidance the Underlying Security may provide may not ultimately be accurate. If the Underlying Security’s guidance is not accurate or varies from actual results due to its inability to meet the assumptions or the impact on its financial performance that could occur as a result of various risks and uncertainties, the market value of the Underlying Security could decline significantly.

 

REX WMT Growth & Income ETF | UNDERLYING SECURITY TRADING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

UNDERLYING SECURITY TRADING RISK. The trading price of the Underlying Security may be highly volatile and could continue to be subject to wide fluctuations in response to various factors. The stock market in general, and the market for companies such as the Underlying Security in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, a large proportion of the Underlying Security may be traded by short sellers which may put pressure on the supply and demand for the common stock of the Underlying Security, further influencing volatility in its market price. Public perception and other factors outside of the control of the Underlying Security may additionally impact the Underlying Security’s price due to the Underlying Security garnering a disproportionate degree of public attention, regardless of actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against companies such as these. Any judgment against the Underlying Security, or any future stockholder litigation, could result in substantial costs and a diversion of the management of the Underlying Security’s attention and resources. If the Underlying Security’s trading is halted, trading in Shares of the Fund may be impacted, either temporarily or indefinitely.

Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns.

In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

 

REX WMT Growth & Income ETF | CASH TRANSACTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CASH TRANSACTIONS RISK. The Fund currently expects to effect a significant portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted.

 

REX WMT Growth & Income ETF | CLEARING MEMBER DEFAULT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CLEARING MEMBER DEFAULT RISK. Transactions in some types of derivatives, including the options held by the Fund, are required to be centrally cleared (“cleared derivatives”). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearinghouse, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearinghouses, and only members of a clearinghouse (“clearing members”) can participate directly in the clearinghouse, the Fund will hold cleared derivatives through accounts at clearing members. With regard to its cleared derivatives positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearinghouse through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing member’s individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options position may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearinghouse, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member’s bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing member’s default. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund’s ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX WMT Growth & Income ETF | COMPOUNDING RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COMPOUNDING RISK. While the Fund’s primary investment objective is to pay weekly distributions, the Fund’s secondary investment objective is to seek daily investment results, before fees and expenses, between 105% and 150% of the daily percentage change of the Underlying Security. Therefore, the performance of the Fund for periods longer than a single day will very likely differ in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security for the same period. Compounding affects all investments, but has a more significant impact on a leveraged fund. This effect becomes more pronounced as volatility and holding periods increase.

 

REX WMT Growth & Income ETF | CONCENTRATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CONCENTRATION RISK. The Fund will concentrate in the securities of a particular industry or group of industries to which the Underlying Security is assigned. To the extent the Fund has significant exposure in a single asset class or the securities of issuers within the same country, state, region, industry or sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A significant exposure makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is more broadly diversified.

 

REX WMT Growth & Income ETF | CORRELATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

CORRELATION RISK. There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Security and therefore achieve its targeted daily leveraged investment objective. Failure to achieve a high degree of correlation may prevent the Fund from achieving its daily investment objective, and the percentage change of the Fund’s NAV each day may differ, perhaps significantly in amount, and possibly even direction, from the targeted daily leveraged return of the Underlying Security on a given day. A number of other factors may adversely affect the Fund’s sought-after targeted daily leveraged correlation, including fees, expenses, transaction costs, financing costs related to the use of derivatives, accounting standards and their application to income items, disruptions, illiquid or high volatility in the markets for the securities or financial instruments in which the Fund invests, early and unanticipated closings of the markets on which the holdings of the Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions, regulatory and tax considerations, which may cause the Fund to hold (or not to hold) the Underlying Security. The Fund may take or refrain from taking positions in order to improve tax efficiency, comply with regulatory restrictions, or for other reasons, each of which may negatively affect the Fund’s correlation with daily changes in the price of the Underlying Security. The Fund may also be subject to large movements of assets into and out of the Fund, potentially resulting in the Fund being under- or over-exposed to the Underlying Security. Any of these factors could decrease correlation between the performance of the Fund and daily changes in the price of the Underlying Security and may hinder the Fund’s ability to meet its daily investment objective.

 

REX WMT Growth & Income ETF | COSTS OF BUYING AND SELLING FUND SHARES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COSTS OF BUYING AND SELLING FUND SHARES RISK. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

 

REX WMT Growth & Income ETF | COUNTERPARTY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COUNTERPARTY RISK. The Fund is subject to counterparty risk by virtue of its investments in options contracts. Transactions in some types of derivatives, including options, are required to be centrally cleared (cleared derivatives). In a transaction involving cleared derivatives, the Fund’s counterparty is a clearing house rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house (clearing members) can participate directly in the clearing house, the Fund will hold cleared derivatives through accounts at clearing members. In cleared derivatives positions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through their accounts at clearing members. Customer funds held at a clearing organization in connection with any options contracts are held in a commingled omnibus account and are not identified to the name of the clearing members’ individual customers. As a result, assets deposited by the Fund with any clearing member as margin for options may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing member. In addition, although clearing members guarantee performance of their clients’ obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing members’ bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing members’ customers for the relevant account class. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund’s behalf, which heightens the risks associated with a clearing members’ default. This risk is greater for the Fund as it seeks to hold options contracts on a single security, and not a broader range of options contracts, which may limit the number of clearing members that are willing to transact on the Fund’s behalf. Additionally, increased volatility in a single security may lead clearing members to lower position limits or place other restrictions that could prevent the Fund from achieving its investment strategy. If a clearing member defaults, the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. If the Fund cannot find a clearing member to transact with on the Fund’s behalf, the Fund may be unable to effectively implement its investment strategy.

 

 

REX WMT Growth & Income ETF | CYBER SECURITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cyber security Risk. The Fund is susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund’s digital information systems through “hacking” or malicious software coding but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund’s third-party service providers, such as its administrator, transfer agent, custodian, or sub-adviser, as applicable, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third-party service providers.

 

REX WMT Growth & Income ETF | DEBT SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DEBT SECURITIES RISK. The Fund will invest in various types of debt securities, which may be used for collateral for the Fund’s options contracts and/or swap agreements and may be used to generate additional income. Investments in debt securities subject the holder to the credit risk of the issuer. Credit risk refers to the possibility that the issuer or other obligor of a security will not be able or willing to make payments of interest and principal when due. Generally, the value of debt securities will change inversely with changes in interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. During periods of falling interest rates, the income received by the Fund may decline. If the principal on a debt security is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. Debt securities generally do not trade on a securities exchange making them generally less liquid and more difficult to value than common stock.

 

REX WMT Growth & Income ETF | DERIVATIVES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DERIVATIVES RISK. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation, and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be imperfect correlation between the value of the underlying instrument and the derivative, which may prevent the Fund from achieving its investment objectives. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

 

REX WMT Growth & Income ETF | OPTIONS CONTRACTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

OPTIONS CONTRACTS RISK. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the options contract and economic events. For the Fund in particular, the values of the options contracts in which it invests are substantially influenced by the values of the underlying instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to expiry, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. As the options contracts are exercised or expire the Fund will enter into new options contracts, a practice referred to as rolling.

 

 

REX WMT Growth & Income ETF | COVERED CALL OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

COVERED CALL OPTIONS RISK. A covered call strategy involves writing (selling) covered call options in return for the receipt of premiums. The seller of the option gives up the opportunity to benefit from price increases in the underlying instrument above the exercise price of the options but continues to bear the risk of underlying instrument price declines. The premiums received from the options may not be sufficient to offset any losses sustained from underlying instrument price declines over time. As a result, the risks associated with writing covered call options may be similar to the risks associated with writing put options. Exchanges may suspend the trading of options during periods of abnormal market volatility. Suspension of trading may mean that an option seller is unable to sell options at a time that may be desirable or advantageous to do so.

 

REX WMT Growth & Income ETF | PUT OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PUT OPTIONS RISK. Purchasing and writing put options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities. The risk associated with selling a put option is that the market value of the underlying security could decrease and the option could be exercised, obligating the seller of the put option to settle the transaction at an exercise price that is higher than the prevailing market price. If the Fund is not able to sell an option held in its portfolio, it would have to exercise the option to realize any profit and would incur transaction costs upon the purchase or sale of the underlying securities. Ownership of options involves the payment of premiums, which may adversely affect the Fund’s performance. To the extent that the Fund invests in over-the-counter options, the Fund may be exposed to counterparty risk. A long put option gives the purchaser of the option the right to sell a specified quantity of an underlying asset at a fixed exercise price over a defined period of time. Purchased put options may expire worthless and the Fund would lose the premium it paid for the option.

 

REX WMT Growth & Income ETF | SWAP AGREEMENTS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to shares of the underlying reference asset. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference asset does not perform as anticipated. In addition, many swap agreements trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

 

 

REX WMT Growth & Income ETF | DISTRIBUTION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION RISK. As part of the Fund’s investment objectives, the Fund seeks to provide current income. There is no assurance that the Fund will make a distribution at any given time. If the Fund does make distributions, the amounts of such distributions will likely vary greatly from one distribution to the next. Additionally, the distributions, if any, may consist of returns of capital, which would decrease the Fund’s NAV and trading price over time. As a result, an investor may suffer significant losses to their investment.

 

REX WMT Growth & Income ETF | DISTRIBUTION TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

DISTRIBUTION TAX RISK. The Fund currently expects to make distributions on a regular basis. While the Fund will normally pay its income as distributions, the Fund’s distributions may exceed the Fund’s income and gains for the Fund’s taxable year. The Fund may be required to reduce its distributions if it has insufficient income. Additionally, there may be times the Fund needs to sell securities when it would not otherwise do so and could cause the distributions from that sale to constitute return of capital. Distributions in excess of the Fund’s current and accumulated earnings and profits will be treated as a return of capital. Return of capital distributions do not represent income or gains generated by the Fund’s investment activities and should not be interpreted by shareholders as such. Distributions in excess of the Fund’s minimum distribution requirements, but not in excess of the Fund’s earnings and profits, will be taxable to Fund shareholders and will not constitute nontaxable returns of capital. A return of capital distribution generally will not be currently taxable but will reduce the shareholder’s cost basis and will result in a higher capital gain or lower capital loss when those Fund shares on which the distribution was received are sold. Once a Fund shareholder’s cost basis is reduced to zero, further distributions (in excess of earnings and profits) will be treated as capital gain, if the Fund shareholder holds shares of the Fund as capital assets. Additionally, any capital returned through distributions will be distributed after payment of Fund fees and expenses. Because the Fund’s distributions may consist of return of capital, the Fund may not be an appropriate investment for investors who do not want their principal investment in the Fund to decrease over time or who do not wish to receive return of capital in a given period. In the event that a shareholder purchases shares of the Fund shortly before a distribution by the Fund, the entire distribution may be taxable to the shareholder even though a portion of the distribution effectively represents a return of the purchase price.

DIVIDEND RISK. There is no guarantee that the issuers of the Fund’s portfolio securities will declare dividends in the future or that, if declared, they will either remain at current levels or increase over time.

 

REX WMT Growth & Income ETF | EQUITY SECURITIES RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer.

 

 

REX WMT Growth & Income ETF | FLEX OPTIONS RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

FLEX OPTIONS RISK. Trading FLEX Options involves risks different from, or possibly greater than, the risks associated with investing directly in securities. The Fund may experience losses from specific FLEX Option positions and certain FLEX Option positions may expire worthless. The FLEX Options are listed on an exchange; however, no one can guarantee that a liquid secondary trading market will exist for the FLEX Options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund’s FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund’s FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection could reduce the Fund’s ability to achieve its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities.

HIGH PORTFOLIO TURNOVER RISK. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

 

REX WMT Growth & Income ETF | INDIRECT INVESTMENT RISK [Member]  
Prospectus [Line Items]

INDIRECT INVESTMENT RISK. The Underlying Security is not affiliated with the Trust, the Fund, the Adviser, or any affiliates thereof and is not involved with this offering in any way, and has no obligation to consider the Fund in taking any corporate actions that might affect the value of the Fund. The Trust, the Fund, the Adviser, or any affiliate are not responsible for the performance of the Underlying Security and make no representation as to the performance of the Underlying Security. Investing in the Fund is not equivalent to investing in the Underlying Security. Fund shareholders will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to the Underlying Security.

 

REX WMT Growth & Income ETF | INFLATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INFLATION RISK. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund’s assets and distributions may decline. This risk is more prevalent with respect to fixed income securities held by the Fund.

 

REX WMT Growth & Income ETF | INTEREST RATE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt securities in the Fund’s portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer-term debt securities. Duration is a reasonably accurate measure of a debt security’s price sensitivity to changes in interest rates and a common measure of interest rate risk. Duration measures a debt security’s expected life on a present value basis, taking into account the debt security’s yield, interest payments and final maturity. In general, duration represents the expected percentage change in the value of a security for an immediate 1% change in interest rates. For example, the price of a debt security with a three-year duration would be expected to drop by approximately 3% in response to a 1% increase in interest rates. Therefore, prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration.

 

 

REX WMT Growth & Income ETF | INTRADAY INVESTMENT RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

INTRADAY INVESTMENT RISK. The Fund seeks leveraged investment results from the close of the market on a given trading day until the close of the market on the subsequent trading day. The exact exposure of an investment in the Fund intraday in the secondary market is a function of the difference between the value of the Underlying Security at the market close on the last trading day and the value of the Underlying Security at the time of purchase. If the Underlying Security gains value, the Fund’s net assets will rise by the same amount as the Fund’s exposure. Conversely, if the Underlying Security declines, the Fund’s net assets will decline by the same amount as the Fund’s exposure. Thus, an investor that purchases shares intraday may experience performance that is greater than, or less than, the Fund’s targeted leveraged exposure of the Underlying Security. If there is a significant intraday market event and/or the investments experience a significant change in value, the Fund may not meet its investment objectives, may not be able to rebalance its portfolio appropriately, or may experience significant premiums or discounts, or widened bid-ask spreads. Additionally, the Fund may close to purchases and sales of Fund Shares prior to the close of trading on the Exchange and incur significant losses.

LARGE CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

 

REX WMT Growth & Income ETF | LEVERAGE RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGE RISK. The Fund is subject to leverage risk. When the Fund purchases or sells an instrument or enters into a transaction without investing an amount equal to the full economic exposure of the instrument or transaction, it creates leverage, which can result in the Fund losing more than it originally invested. As a result, these investments may magnify losses to the Fund, and even a small market movement may result in significant losses to the Fund. Leverage may also cause the Fund to be more volatile because it may exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities. Derivative instruments involve a degree of leverage and as a result, a relatively small price movement in derivative instruments may result in immediate and substantial losses to the Fund.

 

REX WMT Growth & Income ETF | LEVERAGED ETF RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LEVERAGED ETF RISK. The Fund may invest in shares of Leveraged ETFs. As a result, the Fund is subject to many of the same risks as if it owned shares of Leveraged ETFs. These risks include the effects of compounding and market volatility, which may cause the performance of a Leveraged ETF over periods longer than a single trading day to differ significantly from the performance of the underlying reference asset. The impact of compounding is magnified in Leveraged ETFs that rebalance daily, especially as volatility and holding periods increase. Leveraged ETFs utilize leverage to obtain investment exposure in excess of its net assets, which can result in greater losses in adverse market conditions than ETFs that do not use leverage. Leveraged ETF also invest in derivatives, which may expose it to greater risks and potentially larger losses than investing directly in the underlying reference assets. Additionally, Leveraged ETFs are subject to counterparty risk, which may result in losses if a counterparty fails to meet its obligations. The performance of Leveraged ETFs is also affected by risks associated with the underlying reference asset, including risks related to the financial services sector and insurance industry, government regulation, economic conditions, interest rate changes, credit market liquidity, cyber security, and other general market risks.

 

REX WMT Growth & Income ETF | LIQUIDITY RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

LIQUIDITY RISK. Some securities held by the Fund, including options contracts, may be difficult to sell or be illiquid, particularly during times of market turmoil. This risk is greater for the Fund as it will hold options contracts on a single security, and not a broader range of options contracts. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

 

 

REX WMT Growth & Income ETF | MARKET MAKER RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

market maker Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund Shares due to a limited number of market makers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund Share price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a discount to NAV and also in greater than normal intraday bid-ask spreads for Fund Shares.

Market Risk. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their NAV, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate.

MONEY MARKET/SHORT-TERM SECURITIES RISK. To the extent that the Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for the Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

OPERATIONAL RISK. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objectives. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

PREMIUM/DISCOUNT RISK. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Fund Shares will approximate the Fund’s NAV, there may be times when the market price of Fund Shares is more than the NAV intraday (premium) or less than the NAV intraday (discount) due to supply and demand of Fund Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund’s portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Fund Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Fund Shares at a time when the market price is at a premium to the NAV of Fund Shares or sells at a time when the market price is at a discount to the NAV of Fund Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

 

REX WMT Growth & Income ETF | PRICE PARTICIPATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

PRICE PARTICIPATION RISK. The Fund employs an investment strategy that includes the sale of call options contracts, which limits the degree to which the Fund will participate in increases in value experienced by the Underlying Security, including the leveraged exposure to the Underlying Security. This means that if the Underlying Security experiences an increase in value above the strike price of the sold call options, the Fund will likely not experience that increase to the same extent and may significantly underperform the Underlying Security. Additionally, because the Fund is limited in the degree to which it will participate in increases in value experienced by the Underlying Security, but has full exposure to any decreases in value experienced by the Underlying Security, including magnified losses to the Underlying Security through the Fund’s use of leveraged instruments, the NAV of the Fund may decrease over any given time period. The Fund’s NAV is dependent on the value of each options portfolio, which is based principally upon the performance of the Underlying Security. The degree of participation in the Underlying Security gains the Fund will experience will depend on prevailing market conditions, especially market volatility, at the time the Fund enters into the sold call options contracts and will vary over time. The value of the options contracts is affected by changes in the value and dividend rates of the Underlying Security, changes in interest rates, changes in the actual or perceived volatility of the Underlying Security and the remaining time to the options’ expiration, as well as trading conditions in the options market. As the price of the Underlying Security changes and time moves towards the options contract’s expiration date, the value of the options contracts, and therefore the Fund’s NAV, will change. However, it is not expected for the Fund’s NAV to directly correlate on a day-to-day basis with the returns of the Underlying Security. The amount of time remaining until the options contract’s expiration date affects the impact of the potential options contract income on the Fund’s NAV, which may not be in full effect until the expiration date of the Fund’s options contracts. Therefore, while changes in the price of the Underlying Security will result in changes to the Fund’s NAV, the Fund generally anticipates that the rate of change in the Fund’s NAV will be different than that experienced by the Underlying Security, especially due to the Fund’s leveraged investment strategy.

REBALANCING RISK. If for any reason the Fund is unable to rebalance all or a part of its portfolio, or if all or a portion of the portfolio is rebalanced incorrectly, the Fund’s investment exposure may not be consistent with its investment objective. In these instances, the Fund may have investment exposure to the Underlying security that is significantly greater or significantly less than its targeted leverage exposure. The Fund may be more exposed to leverage risk than if it had been properly rebalanced and may not achieve its investment objective, leading to significantly greater losses or reduced gains.

 

REX WMT Growth & Income ETF | SPECIAL TAX RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

SPECIAL TAX RISK. The Fund intends to qualify annually and to elect to be treated as a regulated investment company (“RIC”) under the Code. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs, the Fund must, among other things: (i) in each taxable year, derive at least 90% of its gross income from dividends, interest, payments with respect to securities loans and gains from the sale or other disposition of stock, securities or foreign currencies or other income derived with respect to its business of investing in such stock, securities or currencies, or net income derived from interests in certain publicly traded partnerships; (ii) diversify its portfolio holdings so that, at the end of each quarter of the taxable year, (a) at least 50% of the market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities of any one issuer generally limited for the purposes of this calculation to an amount not greater than 5% of the value of the Fund’s total assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, or two or more issuers which the Fund controls which are engaged in the same, similar or related trades or businesses, or the securities of one or more of certain publicly traded partnerships (the “Diversification Tests”); and (iii) distribute at least 90% of its investment company taxable income (which includes, among other items, dividends, interest and net short-term capital gains in excess of net long-term capital losses) and at least 90% of its net tax-exempt interest income each taxable year. There are certain exceptions for failure to qualify as a RIC if the failure is for reasonable cause, or is de minimis, and certain corrective action is taken and certain tax payments are made by the Fund.

 

As noted above, the Fund intends to maintain between 105% and 150% notional exposure to the Underlying Security by entering into financial instruments on the Underlying Security. At least quarterly, the Fund will need to meet the Diversification Tests to maintain its RIC status. This may require selling some financial instruments referencing the Underlying Security in order to purchase other assets that meet the Diversification Tests. Such sales and purchases could affect the investment return of the Fund and may require the Fund to make distributions that were not otherwise required.

 

If the Fund were to fail to meet the qualifying income test or asset diversification test and fail to qualify as a RIC, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income, which would adversely affect the Fund’s performance.

 

 

Additionally, the authority with regard to swap agreements entered into by RICs is unclear both as to the qualification under the income test and the identification of the issuer under the diversification test. The Fund intends to take the position that because the swap agreements held by the Fund reference securities that the income on the swap agreements are “other income” from the Fund’s business of investing in stocks and securities. In addition, the Fund intends to manage its investments in the swap agreements so that neither the exposure to the issuer of the referenced security nor the exposure to any one counterparty of the swap agreements will exceed 25% of the gross value of the Fund’s portfolio at the end of any quarter of a taxable year.

TRADING ISSUES RISK. Although Fund Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund’s assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders.

UNDERLYING ETF RISK. The Fund’s investment in shares of ETFs subjects it to the risks of owning the securities held by the ETF, as well as the same structural risks faced by an investor purchasing shares of the Fund, including absence of an active market risk, premium/discount risk and trading issues risk. As a shareholder in another ETF, the Fund bears its proportionate share of the ETF’s expenses, subjecting Fund shareholders to duplicative expenses.

U.S. GOVERNMENT SECURITIES RISK. U.S. government securities are subject to interest rate risk but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity.

 

REX WMT Growth & Income ETF | VALUATION RISK [Member]  
Prospectus [Line Items]  
Risk [Text Block]

VALUATION RISK. The Fund may hold securities or other assets that may be valued on the basis of factors other than market quotations. This may occur because the asset or security does not trade on a centralized exchange, or in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” assets or securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. The Fund’s ability to value investments may be impacted by technological issues or errors by pricing services or other third-party service providers.

WALMART INC. INVESTING RISK. As of the date of this prospectus, Walmart Inc. faces risks associated with companies in Consumer Staples Distribution & Retail industry group, as well as those related to: issuer-specific attributes that may cause an investment held by the Fund to be more volatile than the market generally; the ability to effectively manage inventory and supply chain operations, which could impact financial performance; challenges in maintaining competitive pricing and customer loyalty amidst intense competition; the need to develop and sustain satisfactory relationships with suppliers and logistics partners to ensure product availability and cost efficiency; risks associated with maintaining store and online sales growth in a rapidly evolving retail environment; exposure to routine legal actions and investigations that could affect reputation and financial stability; difficulties in managing strategic partnerships and expanding into new markets; potential impacts from economic downturns and shifts in consumer spending patterns; the ability to attract and retain key personnel essential for business operations; failure to successfully integrate acquired businesses or realize anticipated synergies; navigating highly regulated business activities and compliance with changing regulations, particularly in labor and environmental standards; reliance on technological infrastructure to support e-commerce and data analytics, with risks related to cyber security threats and data privacy; and additional risks related to financing, litigation, taxes, insurance, and accounting issues. These factors contribute to the volatility and performance of Walmart Inc. relative to the market as a whole.

Risk [Text Block]

CONSUMER STAPLES Distribution & Retail Industry GROUP RISK. Companies in the Consumer Staples Distribution & Retail industry group face significant risks impacting their financial and operational performance. Success is closely tied to economic conditions, interest rates, exchange rates, and supply chain dynamics. These companies rely heavily on disposable income and consumer spending, making them vulnerable to shifts in demographics, preferences, and social trends. Intense competition and cyclical business segments can adversely affect profitability, with seasonal and quarterly fluctuations common. Dependence on third-party suppliers and distribution systems introduces risks of delivery delays, price increases, and quality issues. Intellectual property protection is crucial, as infringement liabilities can arise. Labor costs and regulatory changes can impact financial outcomes, while maintaining customer data security is essential to avoid reputational damage and litigation. International operations expose companies to risks from economic and political instability, currency fluctuations, and trade disputes. Some companies engage in unrelated business lines, introducing additional risks that may affect overall performance. Despite potential success in core activities, these factors pose uncertainties for long-term success.

NON-DIVERSIFICATION RISK. The Fund is classified as “non-diversified” under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the “Code”). The Fund may invest a relatively high percentage of its assets in a limited number of issuers. As a result, the Fund may be more susceptible to a single adverse economic or regulatory occurrence affecting one or more of these issuers, experience increased volatility and be highly invested in certain issuers.
