I downloaded a few 1Minute charts. In many of them, I see a jump from 2023-12-01T00:59:00Z to 2023-11-30T09:00:00Z
Examples include PFE on 2023-12-01 (see a copy here) and PATH on 2023-11-30 (see a copy here)
You can also download them yourself:
api.get_bars(symbol="PFE", timeframe=timeframe, start="2023-12-01, end="2023-12-01, adjustment="split")
api.get_bars(symbol="PATH", timeframe=timeframe, start="2023-11-30, end="2023-11-30, adjustment="split")
Could Support please take a look? Thank you.
