IQFeed - Error: Index 1 out of bounds for length 1

This message indicates there might be Logitech hardware running on your device. Logitech's software updater that runs in the background on your PC uses the same data port that IQFeed does for its history connection. This might create conflicts with IQFeed.

What to do in this case is to end the task for the GHUB Updater process by opening Task Manager > Processes > Search for any LGHUB software that is running > End task.
