Multiple feeds first order is rejected when live with IB

  • H

    I implemented a live version of the 'Multi Example' using IB.

    I had to add the following to the notify_order function due receiving a ValueError (Something to do with indexing an order that didn't exist in the if not order.alive(): statement):

            if order.status == order.Completed:
            return

    It appears that whenever an order is submitted to the broker, the order is initially rejected before being accepted and completed.

2018-12-11T23:53:00 GBP.AUD-CASH-IDEALPRO Order 3 Status Completed

    Although this issue is not affecting performance yet, I was wondering if anyone had an insight as to what was causing it?

    I assume it is the code modification I added above; however, without that modification I am unsure how to manage multiple orders.

    You should activate the _debug parameter of the IBStore. See: Docs - Live Trading - Interactive Brokers

    The most likely explanation is that an error code is being returned, which the code has no provisions for. The default behavior in such a case is to assume the order has been rejected.

    The error codes

            # 100-199 Order/Data/Historical related
        # 200-203 tickerId and Order Related
        # 300-399 A mix of things: orders, connectivity, tickers, misc errors
        # 400-449 Seem order related again
        # 500-531 Connectivity/Communication Errors
        # 10000-100027 Mix of special orders/routing
        # 1100-1102 TWS connectivy to the outside
        # 1300- Socket dropped in client-TWS communication
        # 2100-2110 Informative about Data Farm status (id=-1)

    The documentation from IB is lacking and the error codes were probably added on a "Needed by Institutional Customer X" basis, with some of those codes later gaining ground into the realm of regular customers but with no documentation as to what, how, when and why.

    @backtrader Thank you for that! Feeling stupid for not realising there was a _debug parameter.

    It appears that it was an issue with the order size being below the 20000 IdealPro minimum, resulting in a 399 error code. After amending the order size to meet the minimum criteria, the code which was previously added can be removed:

            if order.status == order.Completed:
            return
    0
