Hi, I am building a Risk Management utility for IB TWS and am facing the following issue: i) I have to disable the IB software once a drawdown limit is reached. The issue I am having is this: The user will be using IB manually - meaning will transmit the order manually. At this point, I have to either allow or deny the order to be transmitted based the dollar amount of the order. To be able to do this I either need to override the IB Transmit method; or have access to an event that will be fired BEFORE the system actually transmits the order. In the latter case, I will write some messaging code to transmit the event back to my Risk Management system. M problem is that I am unable to find any relevant event or find a way to override the Transmit method. Am I in the right direction? Is there a way to achieve this? Any help on this will be greatly appreciated. I look forward to your help.
