Li ta dwe remake ke depans sa yo gaye tranzaksyon nan komès Forex ka rive moute ak komès souvan, Se konsa, si sistèm ou apèl pou komès souvan, ou vle asire w ke li gen kapasite nan simonte depans tranzaksyon sa yo. Faktè nan depans gaye nan pi sistèm w pèdi bon ka byen vit revele yo fè echèk. Erezman nan MT4 pwogram backtesting (yo rele Estrateji tèsteur) Deja faktè soti depans sa yo gaye (oswa omwen a gaye nan moman sa a backtesting), ak sa a karakteristik gaye faktè se yon rezon enpòtan poukisa li se konsa difisil yo kreye yon siksè kap MT4 EA nan backtesting, se pou kont nan tès pi devan.

It should be noted that the spread transaction costs of trading Forex can mount up with frequent trading, so if your system calls for frequent trading, you want to make sure it has the ability to overcome these transaction costs. Factoring in spread costs into most seemingly good systems can quickly reveal them to be failures. Fortunately the MT4 backtesting program (called Strategy Tester) already factors out the spread costs (or at least the spread at that moment of backtesting), and this spread factoring feature is an important reason why it is so difficult to create a successful looking MT4 EA in backtesting, let alone in forward testing. And if your system is a scalping system that depends on the very tight spreads for its performance, it will be a failure if the broker can vary these spreads during those sessions that the scalping system is geared to exploit.
