MQL4 Implementation of onTrade Event Handler – EA MetaTrader 4
by
The code keeps track of orders’ tickets in an CArrayInt. Monitoring the changes to the list of tickets in onTimer it triggers these event handlers:
//+------------------------------------------------------------------+//| Event handler when stop loss is hit |//+------------------------------------------------------------------+void onStopLoss(ulong ticket);
//+------------------------------------------------------------------+//| Event handler when take profit is hit |//+------------------------------------------------------------------+void onTakeProfit(ulong ticket);
//+------------------------------------------------------------------+//| Event handler when a new order is opened |//+------------------------------------------------------------------+void onTradeEntry(ulong ticket);
//+------------------------------------------------------------------+//| Event handler when an order is closed(removed) |//+------------------------------------------------------------------+void onTradeExit(ulong ticket);
note: Not all features of the MQL5 onTradeTransaction handler has been implemented here. It is just a basic approach.
