Hey Jerry, I notice that QCharts won't go back more than one day. I think you mentioned at one time that we'll have to leave it open if we want to get all the data, unlike, say, Prophet.net's feed where you can instantly backfill for ten days.
Am I correct? Does the QCharts backfill have a bug or something that won't let you backfill for ten?
Sorry for asking so many questions lately. I just started backtesting and I've been doing it nonstop last couple of weeks, and I'm trying to figure out all my options, including good data feeds -- I'm noticing some distinct discrepencies with different data feeds within QT, so...
