I am working on this problem for several weeks now and I just can't find a proper way to solve it. I am looking for help. I want the following to happen: Place 2 orders, n and n+1. n has a TP & SL level, n+1 has only SL level. SL levels are the same for both orders. If SL is hit, fine. Both orders are terminated. If TP on order n is hit, modify order n+1 to have its SL moved to the price where order n hit TP. After that I want to execute trailing stop loss and I have already programmed that successfully. How is this done? I tried with magic numbers, iterating over HistoryDealsTotal, HistoryOrdersTotal and a few more approaches but I just never get to the point where I am able to track an order inbetween many open orders and check if it just hit TP, then modify the other order that was initially created right after the first order. I would appreciate any help towards a solution, thanks!

After doing some research, I came up with a solution to the problem above. here is a breakdown. I looped through my order history and recorded the following; OrderOpenTime(); OrderSymbol(); OrderType(); OrderLots(); Note: the data you record is up to you. I then loop through the OrdersTotal with the data I have got for possible matches and then modify the match. Hence; datetime OrderDateTime=0; // variable to store the OrderOpenTime string orderSymbol=""; int orderType=0 ; double orderLot=0.0; int TotalHistoryOrders = OrdersHistoryTotal(),TotalOrders=OrdersTotal(); for(int h = TotalHistoryOrders - 1; h >= 0; h--) { if(OrderSelect(h, SELECT_BY_POS, MODE_HISTORY)) // checking through orderHistory { if(OrderSymbol() == _Symbol) { if(OrderType() == OP_SELL || OrderType() == OP_BUY) { if(OrderProfit() >= 0) // checking if the closed trade was in profit { //saving the needed data from the history data OrderDateTime = OrderOpenTime(); orderSymbol = OrderSymbol(); orderType = OrderType(); orderLot = OrderLots(); } for(int i = TotalOrders - 1; i >= 0; i--) { //checking opened trades for a possible match if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) if(OrderOpenTime() == OrderDateTime|| OrderOpenTime() == OrderDateTime+1) // +1 just incase the second order opens a second later { if(OrderSymbol() == orderSymbol) { if(OrderType() == orderType) { if(OrderLots() == orderLot) { // CHEKING IF STOP LOSS IS BELOW ONBAR_STOPLOSS if(OrderStopLoss() < Onbar_stoploss(OP_BUY)) // Onbar_stoploss is my stoploss function for Buy orders { double stop_loss = Onbar_stoploss(OP_BUY); // setting the stoploss //MODIFYING STOP LOSS bool ORDER_MORDIFY1 = OrderModify(OrderTicket(),OrderOpenPrice(), stop_loss, OrderTakeProfit(),0,clrNONE); } else if(OrderStopLoss() > Onbar_stoploss(OP_SELL))// Onbar_stoploss is my stoploss function for sell orders { double stop_loss = Onbar_stoploss(OP_SELL); // setting the stoploss //MODIFYING STOP LOSS bool ORDER_MORDIFY1 = OrderModify(OrderTicket(),OrderOpenPrice(), stop_loss, OrderTakeProfit(),0,clrNONE); } } } } } } } } } } I hope this helps.
