Hi i programming EA and it is work correctly in demo account, But when i want run it on real account i get the error 10004 and 10021.

I read this link "https://www.mql5.com/en/docs/constants/errorswarnings/enum_trade_return_codes" But the definition of some error is not clear and i do not understand what is the problem here exactly.

Please help and explain why these errors are displayed.thank you.

Error 10004 and 10021 are related to wrong price used in your trading request. You always need to use the last available price.

Show the relevant code if you need help.

thank you. this is my open trade function:

You answered partly inside the quote, I have fixed it.

If you are not used with mql I would recommend you to use the Standard Library <Trade.mqh>.

Anyway. What is the value of "ESID" ?

justlink 2023.03.29 04:58 #4

ESID is the Open of current candle and The OpenTrade is called immediately after the current candle is opened.

this is the parameter I pass to opentrade function:

OpenTrade(ORDER_TYPE_SELL,OpenArray[0],vol,myStopLossPoint,ResSup_line,myDeviation_point,3,per,roham3_Time);

So let my try trade.mql too.

You should use symbol last price, not candle open price … we buy at ask and sell at bid

I know that why i MTRquest.deviation parameter.

and i use <Trade.mqh> now. this is my code:

void OpenTrade(ENUM_ORDER_TYPE ENType,double ESID,
               double Volume, double SL, double roham_line, int roham_deviation
               ,int witch_roham,int witch_per, ENUM_TIMEFRAMES witch_timeframe)
  {
   bool resultOrder;
   uint retcodeOrder;
   ulong  dealticketOrder;

   if(ENType == ORDER_TYPE_BUY)
     {
      resultOrder = CT.Buy(Volume,NULL,ESID,roham_line - (SL *_Point) - (SYMBOL_SPREAD * _Point),0.0,NULL);
     }
   else
      if(ENType == ORDER_TYPE_SELL)
        {
         resultOrder = CT.Sell(Volume,NULL,ESID,roham_line + (SL *_Point) + (SYMBOL_SPREAD * _Point),0.0,NULL);
        }
   Sleep(1000);
   retcodeOrder = CT.ResultRetcode();
   dealticketOrder = CT.ResultDeal();

   Alert("retcode:    ", retcodeOrder);
   Alert("ticket:   ", dealticketOrder);
}

the Retcode return correctly and show 10009 in alert too. so the position open. But the ResultDeal always return 0. how can i get the ticket value?

PositionClosePartial returns false but Experts: MA Trend BuyLimit gives invalid price

I asked you to show the relevant code, still you didn't.

ESID is the Open of current candle and The OpenTrade is called immediately after the current candle is opened.

Error 10004 and 10021 are related to wrong price used in your trading request. You always need to use the last available price.

This error is about the price used, show all the relevant code and which price you are using.
