many daily bars of this date are bad. (sip,splitsonly)
see bac,baba,bmy and probably many more 
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 
Hi 
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.
I manually checked the following tickers: AAPL, AMD, F, NIO, TSLA, they all look fine. Can you please provide some examples?

You’re right, the issue is this time with the 2024-11-19 bars for exotic symbols with low trading volume. The root cause I found is that the trades with the official closing prices are missing. Actually this is related to the issue I mentioned in my previous message and unfortunately, I cannot easily fix it. But I’m going to, and will get back to you on this thread once it’s done.
