How to make sure the PositionClosePartial() method is executed correctly?

[Freeexplorer]

Hi guys

My question is which return code are expected after executing ResultRetcode() method When the PositionClosePartial(...) method had been run before that .

as mentioned in the MQL5 document successful completion of the PositionClosePartial(...) method does not always mean a successful execution of a trading operation. after executing  PositionClosePartial(...) we should call the ResultRetcode() method to check the result of a trade request (Return Codes of the Trade Server).

I think ,  checking of  "TRADE_RETCODE_PLACED" or "TRADE_RETCODE_DONE" return values are enough. what do you think?

Thanks for your answer in advance.

                        EA_Trade.PositionClosePartial(PosTicket,PartialExitVolume,ULONG_MAX);
                        int RetCode = EA_Trade.ResultRetcode();
                        if(RetCode==TRADE_RETCODE_DONE || RetCode== TRADE_RETCODE_PLACED) //Request is completed or order placed)

I checked it out with the strategy tester, PositionClosePartial function returns "10009" or TRADE_RETCODE_DONE value if the function completed successfully.

I have a problem where PositionClosePartial returns false but the retcode is 10009. I don't see how that should be possible. The return of false seems correct since the position does not get partially closed.

I tried to trace where this happens in the function, and where it returns false is near the start where it does

/--- check stopped

   if(IsStopped(__FUNCTION__))

      return(false);

I don't know why it would be stopped. I am running the backtest, nothing is stopped. 

Thanks to anyone who has seen this and knows what is causing it.

An update in case anyone sees this one.

I found out to my surprise that my broker only services Forex for customers outside the US. This could explain why I am getting some odd results from the EA.

I can't be sure. But on one other error I was getting it was because of this.

It seems US Forex brokers who allow US customers only support MT4. I will have to try to get a copy from one of them. Or else go back to futures.
