How to prevent EA open new trade when previous trade hit sl?

My ea code :

    double D110RecentBarHighest;
    double D110RecentBarLowest;
    D110RecentBarHighest = iHigh(Symbol(),0,iHighest(NULL,0,MODE_HIGH,110,5));
    D110RecentBarLowest = iLow(Symbol(),0,iLowest(NULL,0,MODE_LOW,110,5));
    
    if (Close[1] > D110RecentBarHighest && buytotal==0 ){
        openBuyTrade();
    }
    
    if (Close[1] > D110RecentBarLowest && selltotal==0){
        openSellTrade();
    }

My ea code :

Trades hitting stoploss would normally have "sl" in trade history comment, maybe you can check that before opening new trade ?

   Some brokers do not put SL in the comment. Not a good idea to use comments, brokers can change comments, including complete replacement.

       if (Close[1] > D110RecentBarHighest && buytotal==0 ){

   You are looking at a signal. Act on a change of signal.

Iterate through all closed trades (OrdersHistoryTotal()), get the most recent one (OrderCloseTime()), check it's close price (OrderClosePrice()) against open price (OrderOpenPrice()) to determine whether it was stopped out by stop loss, then pass this information on to supplement the trade opening conditions in your existing EA code.
