What is it? Scenario Trader (ScT) is an ARTIFICIAL BRAIN that learns by himself to trade E-MINI S&P 500 using traders instructions and preferences and must be treated as a PROFESSIONAL BROKER that knows what to do in any KNOWN situation. Trader's interference is necessary if ScT doesn't recognizes new sequence of market development and therefore cannot make any decision. This is ONLY time to interfere and help him out! In order to trade efficiently ScT and Trader must make up a well trained team where ScT is LEADER and a trader is helper, but still brain behind the team! Trader MUST recognize ScT's leadership just because ScT will enter the market only if he 100% sure in the end result of the action that many times he used during the training. So, you MUST trust his decision to enter the market. But during market development the pattern of market conditions sequence may become unknown to ScT and lead to losses. This is a time for trader to act! After end of such trading day Trader should take a time to train manually ScT for this particular day until ScT will achieve a positive result and next time ScT will perform much better! Interactions with ScT we've made as easy as possible: - "Just-In-Time" traders Actions are buttons on the toolbar. - "Generic Instructions" are check boxes on the risk management console. Trader may use Just-In-Time buttons  in critical situations or when he sees some opportunities in the market development. These actions will be executed immediately. Trader may use Generic instructions for ScT's behavior change to help him out. In this case ScT will use new input to make a decision.
