Post From: Autotrader live order modification fails

The code is detecting the orders, however to cancel an order sierra sends the cancelation to rithmic. The setup has 2 OCO groups, target 1 and target 2. If T1 is hit, Rithimc automatically cancels the SL (oco1). However, it doesn't send a cancelation notification to sierra. So when sierra gets the response that T1 is filled, Sierra wants to cancel the order and sends the cancelation to rithmic. Rithmic then sends a rejection / error in return because it doesn't recognise the order. Sierra gets the error / rejection and keeps the order kinda like a ghost order, because it is not canceled on the broker side..

Thanks again,
