Hi I have EA with code structure like this, void OnTick() { resetCounterVar(); //there's for loop CloseOrders(); //there's for loop UpdateAllOpenOrders(); //there's for loop SetSLTP(); //there's for loop CheckPendOrder(); //there's for loop if(IsNewCandle() && pendingOrderCount<MaxPendingOrder) OpenOrders(); } I want to make the for loop instead for every function into like this, for(int i = OrdersTotal() - 1; i >= 0; i--) { if(OrderSelect(i,SELECT_BY_POS) && OrderSymbol() == Symbol() { resetCounterVar(); CloseOrders(); UpdateAllOpenOrders(); SetSLTP(); CheckPendOrder(); if(IsNewCandle() && pendingOrderCount<MaxPendingOrder) OpenOrders(); What I want to ask does the second code structure more efficient then the first one?
