I don't think brokerCommand will help me because I get real time data and trade via a different broker plugin, selected from the Zorro dropdown list.

Just ran the new DLL and it seems to work fine.

Except that I had to change the default port sequence to: 1099, 11097, and 11098

The old sequence was 1099, 11098, and 11097 before for Listening Port, Historical Data Port, and the TLS Historical Data Port.
