I want to close all open sell trade before opening a buy in the place where I put asterisk sign. Please, can anyone help me with the code? Thank you in advance for your help #include <Trade\Trade.mqh> CTrade trade; input double MyLotSize = 0.01; void OnTick() { double myMovingAverageArray1[],myMovingAverageArray2[]; int movingAverageDefinition1 = iMA (_Symbol,_Period, 20,0,MODE_EMA,PRICE_CLOSE); int movingAverageDefinition2 = iMA (_Symbol,_Period, 50,0,MODE_EMA,PRICE_CLOSE); ArraySetAsSeries(myMovingAverageArray1,true); ArraySetAsSeries(myMovingAverageArray2,true); CopyBuffer(movingAverageDefinition1,0,0,3,myMovingAverageArray1); CopyBuffer(movingAverageDefinition2,0,0,3,myMovingAverageArray2); if((myMovingAverageArray1[0]>myMovingAverageArray2[0])&&(myMovingAverageArray1[1]<myMovingAverageArray2[1])) { double Ask=NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits); Comment ("BUY"); *********************************************************** trade.Buy(MyLotSize,NULL,Ask,0,(Ask+60 * _Point),NULL); } if((myMovingAverageArray1[0]<myMovingAverageArray2[0])&&(myMovingAverageArray1[1]>myMovingAverageArray2[1])) { double Bid=NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_BID),_Digits); Comment ("SELL"); +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ trade.Sell(MyLotSize,NULL,Bid,0,(Bid-60 * _Point),NULL); } }

Try the following - void TryToClose(long type){ if(!PositionSelect(_Symbol))return; if(PositionGetInteger(POSITION_TYPE)!=type)return; trade.PositionClose(_Symbol); } add `TryToClose(POSITION_TYPE_BUY)` before opening a sell order.

You can also use the following: if(PositionsTotal() < PositionsTotals) . PositionsTotal() is a built in mql5 function, and PositionsTotals is a variable you can create and change, so it can be 1, etc. By using this logic, you can only have 1 trade open at a time.
