How to change the remaining quantity of a Bracket Entry Order to Zero when it is partially filled


 

Hi All,

I searched TWSAPI and couldn't find this exactly.? If I missed a post please point me there.

How can I change the quantity of the Bracket Entry Order when it is partially filled?? Thru TWS will be preferred, doesn't have to thru API, since I have to do manual intervention anyway.? I tried setting changing the Order Ticket Outstanding Quantity to ZERO and IBKR wouldn't allow it, says it can't be Zero.? I think it would allow "1".? Maybe I missed something ...

I had a Bracket order this morning (in the paper system) for OSTK Long with the Entry being a STPLMT.? The initial order was for 3900 shrs and it partially filled 1200 shrs.? I wanted to keep the OCOs at 1200 shrs.

How can I alter the Entry order (without disturbing the OCOs) to be 1200 shrs, instead of 3900?? The OCOs were showing 1,200 shrs after the partial fill.

Thanks, as always, and Be Well,
Lou Dudka
