Hi have a simple question I'm using the TWS API java and I find if I enter a OCA order and try to up date one of the orders the API always tries to update the last order of the two. e.g if I have a OCA with a STP order id 342 and LMT order 343 if I then send a request to update 342 TWS tries to update 343 Anyone seen this b4 ?
