How to query if Stop Loss has been triggered

[nowayfra]

Hey guys,

im working on a Expert Advisor and need some help. How can i check if a position has been closed by a triggered Stop Loss? Currently i check if positions are open and if not, i want to know if the last position has been successful closed or as said, triggered by Stop Loss. I searched the docs but until now with no luck. 

It would be great if someone could point me into the right direction, thanks.

1. Some (not all) brokers modify the comment, usually adding "[SL]"

2. bool wasBySL = MathAbs( OrderClosePrice() - OrderStopLoss() ) < MathAbs( OrderClosePrice() - OrderTakeProfit() );

   Remember that stops become market orders, and there will be slippage. So OCP < OSL will not work.

Thanks but i guess this will only work for MT4? Found no mql5 reference to commands like OrderClosePrice() ?

Ok digged it out by myself, here some code for the records (a script)

void OnStart()
{

        datetime to = TimeCurrent(); 
        datetime from = to - PeriodSeconds(PERIOD_D1); // check deals for the current day
        ResetLastError(); 
        if(! HistorySelect(from, to))
                Print(__FUNCTION__, " HistorySelect=false. Error code=", GetLastError()); 
        
        unsigned int numOrders = HistoryOrdersTotal();
        unsigned long ticket = HistoryOrderGetTicket(numOrders - 1);
        
        ENUM_ORDER_REASON reason = 0;
        if(HistoryOrderSelect(ticket))
                reason = HistoryOrderGetInteger(ticket, ORDER_REASON);
        
        if(EnumToString(reason) == "ORDER_REASON_SL")
                Print("ticket ", ticket, "  triggered SL");
}

Why is this thread in the MQL4 section, (bottom of the Root page?) Instead of Root / MT5 EA section?
Next time post in the correct place. The moderators will likely move this thread there soon.

You can use this function:

void OnTradeTransaction(const MqlTradeTransaction &trans, const MqlTradeRequest &request, const MqlTradeResult &result)
{
   
}

here documentation :  OnTradeTransaction - Event Handling - MQL5 Reference - Reference on algorithmic/automated trading language for MetaTrader 5
