Alpaca Minute Bar Data

Hi!

The minute bars from Alpaca Data API do not match with the minute bars I see on say Yahoo charts or thinkorswim or Fidelity charts.

Is it because the alpaca data is not NBBO consolidated and is from five exchanges only?

SO, what do I need to do to get the same bar data as the others? Is Polygon the answer?

Thanks!

@hitoshi Any response to this?

If this is how slow the response is, I am wondering whether this is the right platform for me to sign up for live trading.

I’ve experienced the same issue but when I compare 1-min bar of the same timeframe Alpaca vs Polygon. Wanted to find out why the info is different too.
