1. first loop of the test not always gives the errors. If you run several loops, then it is more likelly to repeat the issue
Program_get_bid.py -f symbols.csv -m REALTIME --data-lines 75 --loops 5 --port 4001
2. "I noticed that I don't have any output files from this script." if you scroll in this discussions, the very first message has the app which outputs much more?
3. "I am on TWS 10.30.1, did you recently update to 10.30 or have you been fighting with this for a while?" I had this issue for more than 2 months now. Ever since 10.30 was promoted to "stable". I updated and immidiatelly run into this.
