Hey Andrew,

Thanks for the update! I just tried it out and no issues on my end with historical data now.

For anyone wondering, I'm using a demo of Sierra as provided by Sierra, but I had the Login fields set to Real when I downloaded price history, gonna try out what happens if I set it to Demo later tonight and re-download the data.
I personally use CQG and IQFeed, so I'll run it using both data sets to see if I get any issues and report back here.

Also, can't thank Andrew enough, thanks for keeping up with this man, big ups!
