did anyone was able to submit OCA group orders ?

[Victor]

this is important to make for hedging and strategies implementation.

i was trying to submit OCA (one cancels all) group orders: for example
a bracket order with two orders.

after checking TWS API, i have set all the relevant for this contract/
order parameters i could find there, like parent ID and oca group. i
tried first to place the two orders and then transmit, and also to
place and transmit at the same time. the result was the same - no
complaints from TWS, orders transmitted, but TWS doesn't show the OCA
field set, so the orders are still individual, not as OCA group.

anyone, tried this before ? appreciate some comment.

Not quite the same, but I have successfully placed bracket orders.  The only thing required was to set the parentID on the LMT and STP orders to be the orderID of the parent order.  They automatically formed an OCA group ensuring that if either side of the bracket triggered, the other side of the bracket would be canceled.
