After reading some articles I removed the SL and TP. But still I am getting same error #4756.
MqlTick last_tick; SymbolInfoTick(_Symbol,last_tick); double Ask = last_tick.ask; double Bid = last_tick.bid; MqlTradeRequest request; MqlTradeResult result; int Total_Trades = 1; double TakeProfit = 0.01; i++; request.action = TRADE_ACTION_DEAL; request.magic = 1; request.order = i; request.price = NormalizeDouble(Ask,4); //request.sl = 0;//NormalizeDouble(Ask-0.02,4); //request.tp = 0;//NormalizeDouble(Ask+TakeProfit,4); request.deviation = 3; request.type = ORDER_TYPE_BUY; request.type_filling = ORDER_FILLING_RETURN; request.comment = "First_Order"; Print("Entry = ",request.price, ", TP = ", request.tp, ", SL =",request.sl); if(OrderSend(request, result)) Print("OrderSent");

- You don't have to set request.order for a BUY. Not sure if it's your problem.
- Can you print the result.retcode when you have an error :
{ Print("OrderSend failed with error #",GetLastError(), " Retcode = ", result.retcode); //return(0); }
- If you can provide code that compiles, it would be more easy to help you.

Please check the code.
You have to modify this line :
MqlTradeRequest request;
to
MqlTradeRequest request = {0};
