Hey there, fellow traders! Today, we’re diving into a crucial aspect of MQL4 programming: implementing the onTrade event handler. This handy little feature helps us keep tabs on our active orders, making our trading experience much smoother.
To kick things off, we’re using a CArrayInt to track order tickets. By monitoring changes to this list in the onTimer function, we can trigger specific event handlers whenever certain actions take place. Here’s a quick rundown:
//+------------------------------------------------------------------+//| 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: This implementation doesn’t cover all the bells and whistles of the MQL5 onTradeTransaction handler. Think of it as a solid starting point!

So there you have it! With these event handlers in your toolkit, you’ll be better equipped to manage your trades effectively. Happy trading!
