I have placed a BO order for 31 qty of a share at 11:20:00, the order got partially filled(25 qty), when I cancelled(time: 11:21:15) the partially filled order my entire position got exited.
also I found that for the above mentioned order exchange_timestamp differs between orders() and order_trades() api call
Ideally, if you cancel the first leg bracket order after it is partially executed then that shouldn't affect already placed second leg orders.
The exchange timestamp will be updated when you send modify or cancel request so it is ok that there is a mismatch between exchange timestamp of order and trade.
