Alpaca daily bars for 2024-11-18 not good

Alpaca Market Data
1

many daily bars of this date are bad. (sip,splitsonly)
see bac,baba,bmy and probably many more :wink:
example for BAC
{“o”:46.72,“c”:46.72,“l”:46.72,“h”:46.72,“v”:10466.0,“t”:“2024-11-18T05:00:00Z”,“vw”:0.0,“n”:119}
Actual real data that actually yes do really happened in the real world:

{
    "status": "OK",
    "from": "2024-11-18",
    "symbol": "BAC",
    "open": 46.75,
    "high": 47.02,
    "low": 46.485,
    "close": 46.72,
    "volume": 29400366,
    "afterHours": 46.72,
    "preMarket": 46.7
}

btw these daily bars WERE OK on 11.19 but magically sometime after they were edited in alpaca and now we get shit data. yay :slight_smile:

Hi :wave:

Thank you for reporting this issue. You’re right, we had a small issue on 2024-11-19 (in after hours) and when we tried to fix that we made a mistake that messed up the 2024-11-18 daily bars.

I fixed them now:

{"c":46.72,"h":47.02,"l":46.485,"n":130925,"o":46.75,"t":"2024-11-18T05:00:00Z","v":32371771,"vw":46.778426}

We’re honestly sorry for the inconvenience. I’m taking steps to make sure this won’t happen again in the future.

Best regards,
Gergely Novák

This still happens for something like 300 tickers for this dates (11/19/2024,11/18/2024).

Could you please maybe run a script checking for them and fixing? if you want I can help.
