New comment
 
Hi guys, please help. i am getting OrderSend Error 138 on strategy tester, what can be the reason, and how can i fix this. I do call the Refreshrates() function before any Ordersend() and i have a wide enough slippage of about 100 pips, but still get error 138 when testing, what can possibly be wrong and how can i fix it. I'm using the M1 chart.

You need to fix your code.

GetLastError() - the function that returns codes of error. Code constants of errors are determined in stderror.mqh file. To draw the text messages use the ErrorDescription() function described in the stdlib.mqh file. Error codes returned from a trade server or client...

    Next time post in the correct place. The moderators will likely move this thread there soon.

  2. Zero means no error. Do not look at _LastError unless there is an error. Check your return codes for errors and report them.

    Only those functions that return a value (e.g. iClose, MarketInfo, etc.) must you call ResetLastError before in order to check after.

  3. Mthokozisi Gumede:  still get error 138 when testing, what can possibly be wrong and how can i fix it.
    Do you really expect an answer?  We can't see your broken code.  There are no mind readers here and our crystal balls are cracked.
