Thank you Andrew for your explanation.

I've still problems connection to IB TWS. In attached image are my settings.
TWS: Port 7497 because it's a demo. Accounts name starts "D"... ActiveX is enabled.
Zorro: Account "Demo" .. "IB (demo)". Login 101, password free.

With tradedesk script I got the error "Can't connect". Check login & TWS port 7496.
Port 7496 is for real accounts, not demo. IB demo is 7497. As I saw Zorro free has no access to accounts.csv. Where can I set the IB port in Zorro?

regards
Chris
