Hi everyone. I have just come across this thread in my search for a solution to the error code 10036. [The https://www.mql5.com/en/docs/constants/errorswarnings/enum_trade_return_codes] referred to above points to error constants that will aid in understanding the errors output by the system, but it does not explain the reason for its occurrence in cases where one can see that there is an open order as in my case.  The code below shows a snippet from my EA to open a long position. Opens an order, then modifies it for stop and profit target.

void open_long()
  {
   buy_placed=_trade.buy(_Symbol,lot_size());

   if(buy_placed==true)
     {
      do(Sleep(100));
      while(PositionSelect(_Symbol)==false);
      double open_price=position_open_price(_Symbol);

      Print("open price: ",open_price);

      double buy_stop=buy_stop_loss(_Symbol,StopLoss,open_price);
      if(buy_stop>0) adjust_below_stop_level(_Symbol,buy_stop);

      double buy_profit=buy_take_profit(_Symbol,TakeProfit,open_price);
      if(buy_profit>0) adjust_above_stop_level(_Symbol,buy_profit);

      if(buy_stop>0 || buy_profit>0)
         _trade.modify_market(_Symbol,buy_stop,buy_profit);
     }
  }

Due to the delay between order placement and response from the server, and the update of positions, I make use of the while statement. On running the back tester bar by bar, I can see the order opened by first line in above function, but the error code 10036 soon shows it's ugly head. As you can see in the log snippet below, there are no messages of the order being closed from its opening, confirmation and to the modification attempt.

I am sure as you can see, there is nowhere in the log where the order is closed, and as of this instance, I am looking at the backtest screen the order is most definitely still open. Please see the screen shot image;

I have gone round with this issue and I am just baffled.  Where am I going wrong. As you can see,the error is systemic, since I cannot act on an order unless if I cannot find it. Here, it's leaving the position exposed without a stop or profit target. I can trail or anything related to order management.  Please help!

You are probably using an hedge account with a code done for netting account only.

Show all relevant code if you need help.

Thanks Alain for your response and advice. Attached are two files, MfsSARMAExpert.mq5 and supporting file MfsTrade.mqh. I have also just checked on whether the account is a hedging account, YES it is. So what does this mean, with regards to my problem please. Thanks

I think I understand why having a hedge account is a problem with my current code.  I have just read this article: https://www.mql5.com/en/articles/2299, and now need to start working on making the changes to my code or switch to the MQL5 Trade Library.

On an hedge account, if you want to modify or close an existing position you always have to specify a ticket number.

Thanks for that Alain. I have been reading a few from here that have helped. Thanks once again.
