Because NT DLL is the bridge between eSignal EFS and NT, and it involves much network communication between NT DLL and NT API server(though on local machine), which function calls in NT DLL are blocking and which are unblocking calls?
When I trade three IB TWS accounts, I may see noticable delay from the time the orders are sent out and the orders shown in all three IB TWS. In some case the delay between the time the order shown in the first IB TWS to the time the oder shown in the third IB TWS window may reach half to one second. Among the foue entities (eSignal, NT DLL, NT and IB TWS), which one contributes to the most delay?
