Hi,

I'm interested in DoubleStrike (NASDAQ 100) trading system with WealthSignals subscription. How can I subscribe to this system ? How can I contact the author of the system ? I would have some questions before subscription. Is there a trial period for this system, how long ?

All new systems published in WealthSignals undergo a 30-day probationary period before subscriptions are accepted. (See the Status block.) During this period the author must demonstrate consistent signal entry without violating the "2-day rule", i.e., if they miss entering signals for 2 consecutive market sessions, the probationary period starts over.

This period also allows a minimal build up of out-of-sample testing data. We encourage all potential subscribers to watch how an out-of-sample test develops to judge whether or not it is within the parameters of the in-sample test. How long you watch is up to you. As a rule of thumb, you can expect that an out-of-sample test have twice as much drawdown and half the profit of an in-sample test.

When the probation period ends, a "Subscribe" button will appear on the system details page.

Use the forum on the system page.

For now, WealthSignals supports only 30-day trial periods.

Note: you can contact a system author only after subscribing to his system (I think that a free trial also counts).

Sorry but I don't understand what does an out-of-sample test and an in-sample test mean. Could you explain it ?
