IB API : Excel ‘103 Duplicate order id’ error

Discussion in 'Automated Trading' started by betcashrun, Feb 16, 2010.

  1. After having operated successfully with the TwsDde.xls, I have problems with it now. I am not able to send orders from the spreadsheet: the error is ‘103 Duplicate order id’.
    The environment is: IB API 9.62, MS Excel 2003, Windows XP

    I read somewhere that when sending an order via the spreadsheet the tws applet reads from a database the highest id number from the last activity and ignores any orders with id numbers lower than this as ‘possible duplicates’.

    Do you know where/how to get this last id number or how to fix this error?

    Depending on your tws version, there should a "reset API order id sequence" button in tws, "configure", "API", "all API settings"...

    Otherwise, go to the jts folder in C:, open dglfh...vv or dglfh..vn folders( I don't remember which one it is), open Tws.xml and search for "ddeidmap" in that document. There will a number , reset it to 0.
  3. Thank you very much Tradator. It works now.:D
