I am attempting to use the piece of code (see below) to place orders to TWS.? ?it works fine executing the orders on the demo account with confirmation?from TWS as expected...? However when connected to live mode it does not execute successfully although connection to?TWS is confirmed..? The objective is to have this code running?continuously in the background executing trade files from a trade folder....

?

Not a python expert so excuse minor details!..? just concentrating on getting this to work in the live mode

?

Any help appreciated..? thanks

?

regards

ed
