How to work correctly in MT5 with OrderSend - page 2

This is already a terminology argument. The bad situation has been described in detail above. Standard libraries don't even take that into account.

No.

But keep persisting. I won't explain it any further.

People write about it on the forum. And more than once. The reaction is just that.

People don't want to think for themselves, but want others to do it for them... Unfortunately this is the case.

Do you want me to help you bypass these mishaps (from personal experience of trading with MT5 robots on a real account)?

Waiting for server response after sending OrderSend()

The function is synchronous, just the history is not updated synchronously with the completion of this function,

I'm doing it this way, I think it's easier than tinkering with OnTrade(), and other stuff:

bool ClosePosition()
{
   if (!PositionSelect(_Symbol))
   {
      return(false);
   }

   bool   b_Result;
   
   b_Result = m_trade.PositionClose(_Symbol,mi_Deviation);
   
   if(!b_Result)
   {
      Print("The PositionClose() method has failed. Return code=",m_trade.ResultRetcode(),
            ". Code description: ",m_trade.ResultRetcodeDescription());
      return(false);
   }
   
   if(b_Result)
   {
      if (m_trade.ResultRetcode() == TRADE_RETCODE_DONE)
      {
         while(PositionSelect(_Symbol))
         {
         }
         
         Print("The PositionClose() has been successfully executed. Return code=",m_trade.ResultRetcode(),
               " (",m_trade.ResultRetcodeDescription(),")");
         return(true);
      }
      if (m_trade.ResultRetcode() != TRADE_RETCODE_DONE)
      {
         Print("The PositionClose() failed. Return code=",m_trade.ResultRetcode(),
               " (",m_trade.ResultRetcodeDescription(),")");
         return(false);
      }
   }
   return(false);
}

People not only think but also share their solutions. The developers are silent on this, unfortunately.

Not a single example in the Documentation on this topic. And this is with the main function.

The example you gave above is, excuse me, complete nonsense.

That's not the place to start!

If an OrderSend is sent, you have to REMEMBER (this is where the potential vulnerability is) that it is done. Then disregard the current history (trading environment) until the appropriate OnTrade message arrives. Once it arrives, REMEMBER to FORGET.

When there is no REMEMBER, you can trust the history as in MT4.

Take advantage.

 
prostotrader:

Use it.

So how is it different from what I wrote above? A good man even sent me a serious bible on the subject.

People are finding solutions. It was about the fact that the developers themselves don't even have it in the SB.

If you don't like it, don't use it.
