| Portfolio Turnover [Text Block] | rr_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal period, the Fund’s portfolio turnover rate was 50.88% of the average value of its portfolio. |

| Expense Example Narrative [Text Block] | rr_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at those periods. The Example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and that the contractual expense limitation agreement remains in place for the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategies | ||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in the stock of domestic and foreign issuers that are participating in or benefitting from the development of the resources in the Mid-North America area, encompassing the states of Arizona, Arkansas, Colorado, Illinois, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, Texas, Wisconsin, and Wyoming; and the Canadian provinces of Alberta, Manitoba, and Saskatchewan (herein referred to as the “Region”). To pursue this strategy, the Fund invests primarily in companies that are (i) headquartered or maintain their principal place of business in the Region, or (ii) during the issuer’s most recent fiscal year, derived at least 50% of their revenues from goods produced or sold, investments made, or services performed in the Region, or (iii) during the issuer’s most recent fiscal year, have at least 50% of their assets in the Region, each as determined at the time of purchase.
The Fund may invest in companies of any size. The companies in which the Fund invests may include smaller companies that have recently commenced operations and do not have significant revenues. The Fund’s investment adviser, Viking Fund Management, LLC (the “Investment Adviser”), will invest a significant amount of the Fund’s assets (although not exclusively) in companies it believes to have investment potential in the natural resources area (primarily energy and to a lesser extent, agribusiness, precious metals, and metals and mining), as well as in the companies that serve these sectors and/or service the Region. In connection with investing in companies engaged in the energy sector, the Fund may invest in companies that engage in hydraulic fracturing (which involves the injection of water, sand and chemicals under pressure into rock formations to stimulate oil or natural gas production). The Fund will invest primarily in the securities of U.S. issuers, but it may also invest in the securities of foreign issuers. The Fund’s investments in the securities of foreign issuers are typically in the form of depositary receipts, such as American Depositary Receipts (“ADRs”).
The Fund’s portfolio management team considers a variety of factors when choosing investments for the Fund such as: (i) identifying companies and industries that appear to have the potential for above-average long-term performance based on projections of supply and demand of a resource and the state of the market; and/or (ii) identifying companies that are expected to show above-average growth over the long term as well as those that appear to be trading below their true worth. The Fund’s portfolio management team may consider selling a security if, among other considerations, its business fundamentals have deteriorated. |
||||||
| Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings made for investment purposes) in the stock of domestic and foreign issuers that are participating in or benefitting from the development of the resources in the Mid-North America area, encompassing the states of Arizona, Arkansas, Colorado, Illinois, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, Texas, Wisconsin, and Wyoming; and the Canadian provinces of Alberta, Manitoba, and Saskatchewan (herein referred to as the “Region”).

| Integrity Mid-North American Resources Fund | Risk Lose Money [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | As with all mutual funds, there is the risk that you could lose money through your investment in the Fund. | ||||||
| Integrity Mid-North American Resources Fund | Risk Not Insured Depository Institution [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. | ||||||
| Integrity Mid-North American Resources Fund | Risks of the Energy Sector [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of the Energy Sector: The Fund may invest significantly in securities of companies in the energy sector. The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector are affected by a variety of factors related to worldwide energy prices, exploration costs, energy conservation efforts and production spending. The performance of these companies and the prices of these securities are subject to changes in currency exchange rates, government regulation, world events and weather, depletion of natural resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. The price of oil, natural gas and other fossil fuels could decline significantly and experience significant volatility, and adversely impact companies operating in the energy sector. Further, companies in the energy sector may be at an increased risk of civil liability and environmental damage claims, and are also subject to the risk of loss from terrorism. | ||||||
| Integrity Mid-North American Resources Fund | Geographic or Regional Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Geographic or Regional Risk: The Fund is managed to take advantage of what the Investment Adviser views as unique opportunities within the Region. The geographic limitations of such an approach pose special risks that should be understood by investors. Geographic limitations prevent the Fund from investing in other places where the opportunities may be greater. The economy of the Region may underperform that of other areas, creating a drag on performance relative to more geographically diverse funds. Moreover, the Fund will be more susceptible to events negatively affecting the Region than more geographically diverse funds. The geographic limitation may limit the degree of business diversification of the Fund, thus making returns more volatile than in more geographically diversified investments. | ||||||
| Integrity Mid-North American Resources Fund | Regulatory Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Regulatory Risk: The Fund may invest in companies that are subject to significant federal, state, and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained, and operated, environmental and safety controls, and the prices they may charge for the products and services they provide. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them, and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions, or both. Stricter laws, regulations, or enforcement policies could be enacted in the future which would likely increase compliance costs and may adversely affect the operations and financial performance of a significant number of the companies in which the Fund invests. | ||||||
| Integrity Mid-North American Resources Fund | Risks of Legislation and Regulatory Initiatives Relating to Hydraulic Fracturing [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of Legislation and Regulatory Initiatives Relating to Hydraulic Fracturing: The Fund may invest in companies that engage in hydraulic fracturing. Federal, state, and local legislation and regulatory initiatives relating to hydraulic fracturing (also referred to as “fracking”) could result in increased costs and additional operating restrictions or delays affecting a significant portion of the companies in which the Fund invests. Any federal, state or local laws, implementing regulations or other legal requirements imposing disclosure, regulatory or reporting obligations on, or otherwise limiting, the hydraulic fracturing process, may make it more difficult and expensive to perform hydraulic fracturing, which, for affected companies, could result in limitations on the productive capability of certain oil and gas wells, operational delays, and increased costs of compliance and doing business and, in addition, could adversely affect the value of such companies’ securities. | ||||||
| Integrity Mid-North American Resources Fund | Risks of the Agribusiness Sector [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of the Agribusiness Sector: The Fund may invest in companies involved in agribusiness. Companies involved in agribusiness are subject to numerous risks, including cyclicality of revenues and earnings, economic recession, currency fluctuations, changing consumer tastes, extensive competition, weather conditions, quotas, product liability litigation, and governmental policies, regulation and subsidies. Generally, agribusiness is affected by the economic health of consumers. A weak economy and its effect on consumer spending would adversely affect agribusiness companies. Other risks of the agribusiness sector include consolidation, domestic and international politics, and excess capacity. In addition, agribusiness companies may be significantly affected by volatility of commodity prices, import controls, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices. | ||||||
| Integrity Mid-North American Resources Fund | General Market Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | General Market Risk: There is no assurance that the Fund will meet its investment objective. The prices of the securities in which the Fund invests may fluctuate as a result of market factors such as interest rates, credit spreads, or commodity prices, and the Fund’s share price and the value of your investment may change. Since the value of the Fund’s shares can go up or down, it is possible to lose money by investing in the Fund. | ||||||
| Integrity Mid-North American Resources Fund | Style Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Style Risk: The Fund is managed according to an investment strategy that at times reflects either growth or value style investing, and therefore is subject to the risks associated with these styles. One risk is that a growth investing style may fall out of favor with investors for a period of time during which the Fund may underperform other funds that employ a different style. In addition, growth stocks typically are more volatile than value stocks due to their relatively high valuations and sensitivity to investor perceptions of the issuer’s growth potential. As a result, the price of a growth stock may experience a larger decline on a forecast of lower earnings or other negative development, than would a value stock. Furthermore, because the value of growth companies is a function of their expected earnings growth, there is a risk that such earnings growth may not occur or cannot be sustained. Value stocks may continue to be undervalued by the market for extended periods, including the entire period during which the stock is held by the Fund. Additionally, the events that the Investment Adviser believed would cause the stock price to increase may not occur as anticipated or at all. Moreover, a stock judged to be undervalued actually may be appropriately priced at a low level. | ||||||
| Integrity Mid-North American Resources Fund | Sector and Sector Weightings Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Sector and Sector Weightings Risk: Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single sector and the securities of companies in that sector could react similarly to these or other developments. Since the Fund invests significantly in relatively few sectors, primarily the energy sector, it has more exposure to the price movements of this sector than funds that diversify their investments among many sectors. | ||||||
| Integrity Mid-North American Resources Fund | Risks of Foreign Securities (including Depositary Receipts) [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of Foreign Securities (including Depositary Receipts): The Fund may invest in securities of non- U.S. issuers, which have special risks. These risks include international economic and political developments, foreign government actions including restrictions on payments to non-domestic persons such as the Fund, less regulation, less information, currency fluctuations, and interruptions in currency flow. The Fund’s investments in foreign securities are typically in the form of sponsored or unsponsored depositary receipts, such as ADRs, which are subject to risks similar to those associated with other foreign securities. In addition, ownership of unsponsored depositary receipts may not entitle the Fund to financial and other reports from the issuer of the underlying security and certain costs related to the receipts that would otherwise be borne by the issuer of a sponsored depositary receipt may be passed through, in whole or in part, to holders of unsponsored receipts. Moreover, investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. | ||||||
| Integrity Mid-North American Resources Fund | Liquidity Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Liquidity Risk: Certain securities in which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities. These features may make it more difficult to sell or buy a security at a favorable price or time. | ||||||
| Integrity Mid-North American Resources Fund | Risks of Investments in Smaller Companies [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Risks of Investments in Smaller Companies: The securities of mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Both mid-capitalization and small-capitalization companies often have narrower markets and more limited managerial and financial resources than more established companies. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund’s portfolio. Generally, the smaller the company size, the greater these risks become. | ||||||
| Integrity Mid-North American Resources Fund | Valuation Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk: The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. | ||||||
| Integrity Mid-North American Resources Fund | Cybersecurity Risk [Member] | ||||||||
| Risk/Return: | rr_RiskReturnAbstract | |||||||
| Risk [Text Block] | rr_RiskTextBlock | Cybersecurity Risk: Cybersecurity breaches may allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause the Fund and/or its service providers to suffer data corruption or lose operational functionality. The Fund’s share price may decline as a result of unauthorized actions taken during a security breach or subsequent market activity in response to the security breach. | ||||||
