Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
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 year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock Investment Research Corporation (the "Adviser") manages the Fund by searching for companies/investments with growth potential that could show faster growth than markets indexes. The Adviser also looks for securities that are considered undervalued or out of favor with investors or are expected to increase in price over time. We use a consistent approach to build the Fund’s security portfolio which is made up primarily of common stocks involved, in at least some way, in the legal cannabis business. In addition to the principal investment strategy, we may also invest in securities convertible into common stock in companies involved, in at least some way, in the legal cannabis business. Examples of companies associated with the legal cannabis industry could include legally registered publicly traded companies in fields such as agriculture, pharmaceutical, hydroponic or tobacco companies or REITs. These securities may be issued by large companies and also small and mid-sized companies, Micro Cap and REITs. Income through dividend payments is a secondary objective. Income also becomes a Fund objective when it is in a temporary, defensive position. The legal cannabis business does not need to be the sole focus point of a company for Series Two to invest in it nor does it need to account for a majority of its overall revenues. For example, Series Two may invest in Company XYZ, a pharmaceutical company developing uses for medical cannabis even if the revenues produced as a result of the sales of medical cannabis is responsible for less than 5% of XYZ’s overall revenue.
Risk [Heading] rr_RiskHeading Principal risks of investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock The primary risks of investing in the Fund are:

General Risk - All investments are subject to inherent risk. Markets can trade in random or cyclical price patterns and prices can fall over time. The value of Series Two can fluctuate as markets fluctuate over long and short periods of time.

Political, Economic and Regulatory Risk - Changes in economic and tax policies, high inflation rates, government instability, and other political or economic actions or factors that may have an adverse effect on Series Two. Governmental and regulatory actions, including law changes, may have unexpected or adverse consequences on particular markets, strategies, or investments. Legislation or regulation may also change the way in which Series Two itself is regulated. Series Two cannot predict the effects of any new governmental regulation or law that may be implemented on the ability of Series Two to invest in certain assets, or the possible effect on our ability to access financial markets, and there can be no assurance that any new governmental regulation will not adversely affect Series Two’s ability to achieve its investment objectives,

Cannabis Industry Risk – The cannabis industry is a very young, fast evolving industry with possible increased exposure to rule changes, changes in laws, increasing regulations, increasing competition which may cause businesses to suddenly close or businesses to shrink as well as the possibility that a company currently operating legally may suddenly find itself exposed to illegal activities.

REITs Risk - Under its modified fundamental investment policies, Series Two may invest in REITs (Real Estate Investment Trust), including Equity REITs and Mortgage REITs. Equity REITs invest directly in property while Mortgage REITs invest in mortgages on real property. REITs may be subject to certain risks associated with the direct ownership of real property including declines in the value of real estate, risks related to general and local economic conditions, over building and increased competition, increase in property taxes and operating expenses, and variations in rental income. REITS are dependent on management skills, are not diversified, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation. REITs (especially mortgage REITs) are also subject to interest rate risk. When interest rates decline, the value of a REIT’s investment in fixed-rate obligations can be expected to rise. Conversely, when interest rate rise, the value of a REIT’s investment in fixed-rate obligations can be expected to decline. Mortgage REITs may be affected by the quality of any credit extended to them,

Stock Market Risk - the value of an investment may fluctuate,

Industry and Security Risk - risks relating to an industry as a whole or a company’s prospects for business success,

Management Risk - risks that the Adviser’s assessment of a company’s growth prospects may not be accurate,

Liquidity Risk - Series Two may face increased liquidity risk which is the risk that a given security or asset may not be readily marketable,

Small Cap Risk - small cap stocks tend to have a high exposure to market fluctuations and failure,

Mid Cap Risk - mid cap stocks tend to have a greater exposure to market fluctuations and failure,

Micro Cap Risk - low-priced stocks issued by the smallest of companies. Many microcap companies do not file financial reports with the SEC, so it’s hard for investors to get the facts about the company’s management, products, services, and finances. Microcap stocks historically have been more volatile and less liquid than the stock of larger companies,

Convertible Security Risk - risk of loss of principal before maturity,

New Issuer Risk - New Issuers have been in the business less than 3 years, may face increased pressures from established companies, new unseasoned management, may be more volatile and may offer less liquidity then larger companies.

Loss of some or all of the money you invest is a risk of investing in Series Two.
Because of the nature of the Fund, you should consider the investment to be a long-term investment that typically provides the best results when held for a number of years.
Please see the Statement of Additional Information for further discussion of risks.
