MT5 OrderSelect() doesn't work - Order not found - Error Code: 4754

[LiMEntal]

Dear Coders,

I'm working on an MT5 Expert Advisor. I would like to use the OrderSelect() function, but it doesn't work for me. Every time I get "Order not fouund" error message.

Here is my code:

int ot = (int)OrderTicket();
if ( OrderSelect(ot) ){
   Print("OrderSelect done.");    // pr() function is for Print
}
else{
   error_code = GetLastError();
   Print("OrderSelect Error on Ticket #",is(ot),". ",ErrorDescription(error_code),". EC: ",IntegerToString(error_code));
}

Toolbox\Experts output:

"OrderSelect Error on Ticket #280472054. Order not found. EC: 4754"

The position (Ticket #280472054) existed. It was open. But the EA couldn't select it. What can be the problem? What can I try to do?

Thank you in advance.

1. "MT5 OrderSelect() doesn't work." Do you really believe that no one in 10+ years has ever realized this? Or is it more likely that it is you that doesn't understand?

2. The order has opened. It doesn't exist. Select the position.

I still do not understand. But thank you for you answer.

I think, I opened a simple Buy market order (not pending order). It was a deal. Really,, I still don't know exactly what 'deal' means. I'll be back on Monday, and test it again...

You must understand all the concepts and inner workings of an EA, otherwise you will get screwed with unwanted behavior in the future...

Unlike the MQL4, to select an open order in MQL5, you should use PositionSelect(), or PositionSelectByTicket() function to select open orders.
