Good til date - update time - order priority

    I place a buy order on future with a good till time of 10:00am.

    At the time of my order there are 99 orders ahead of me at this price.

    Some orders are hit and some new orders come in. I assume I am moving up the list.

    For sake of argument I am now 50 on the list and it is almost 10:00am.

    I update my time till 10:30am. I don't cancel the order but just update it with the new time.

    My question is does this action move me to the back of the line or do I stay in my current postion?

  2. Good question!

    Are you trading a CME Group product?

    I looked in here ( ) but pg. 12 doesn't mention "modifying" GTC orders (just "execution", "cancelation" and "expiry")

    Thanks for the reply. It is on Vix Futures (CFE)

    I have seen the same info that you mention and as you point out it doesn't seem to address what I was looking for.

    I posed the question to my broker and got a cryptic answer. All they said was that I was sending another message to the exchange. I agree with that but that didn't answer if it was treated as a new order or if I kept my time priority.

    Again, thanks for the feedback.
