I have an EA, I want to do a back test on it in MetaTrader5, I select my EA in strategy tester section and adjust the settings, when I hit start the back testing begins and the chart starts moving but my EA does not buy and sell automatically, I don't know what the problem is, would you please help me to fix this code? Here is my code: //+------------------------------------------------------------------+ //| Property | //+------------------------------------------------------------------+ #property strict //+------------------------------------------------------------------+ //| Global variables | //+------------------------------------------------------------------+ input int MA_Period = 50;

// Take profit level in points double LotSize; // Position size based on risk int Digits; // Number of decimal places for the symbol double AccountBalance = 10000.0; // Account balance in USD //+------------------------------------------------------------------+ //| Expert initialization function | //+------------------------------------------------------------------+ int OnInit() { Digits = int(SymbolInfoInteger(_Symbol, SYMBOL_DIGITS));
