Hi, I noticed that when I buy a position of say, 2000 shares, and set a stop order for those 2000 shares; if I sell 1000 shares, the Stop Order doesn't automatically update. Can this be done automatically? I also noticed that if I set a Sell order, but it is never reached and it crashes out to the Stop Order trigger, the original Sell Order remains. Can I have this automatically removed?
I don't know the answer to your first question. About your second question: you can combine multiple orders in a so-called One Cancels All group (OCA group). When one of the orders in the group is triggered then all other orders in the group get cancelled. I'm sure the TWS user manual has instructions on how to assign an OCA group to a couple of orders.
