Thanks @kzhao.

I was using the Polygon data via the user input described. With Alpaca's change, I figured I'd try the Basic IEX data and see if it's good enough...

Over the weekend, I've searched Alpaca's forum & seen a few posts of users complaining that all the data coming over the API now is messed up since their changeover. Presumably they're working to resolve...

Regards, & thanks!
