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.
