    Hi @anneraghu,
    There was an issue at OMS today. It should be fine now.

    @sujith Thanks,
    What is this error mean "16388 : Unmatched orders cancelled by the system" ?
  • sujith
    I think this is a status message of the IOC order wherein it will either execute immediately if there is any match(seller at the same price) or it gets canceled.

    @anneraghu , @sujith

    Regarding "16388 : Unmatched orders cancelled by the system" -

    Understand that this is for IOC orders. Is it an exception thrown by kite.place_order() or is it received by the on_order_update() callback? Or somewhere else?

    If it is received by the callback, then what is the order status in the postback message? Is it "CANCEL" / "UPDATE" / "COMPLETE" / "REJECTED"?

  • sujith
    The order will be canceled and you will receive an order update for this.
    But place order will return 200 response with order id.

    Sorry, I've to ask for more details as I can't test it myself.

    Say I place an order for 100 shares with validity=IOC. What will be the postback status (CANCEL / UPDATE / COMPLETE / REJECTED) in the following 3 cases?
    Case 1: 40 got filled, remaining 60 got cancelled.
    Case 2: All 100 got filled.
    Case 3: 0 filled, all cancelled.
