StockBarsRequest updated data

Getting Started with Alpaca

Hi,

I used StockBarsRequest to get yesterday’s stock in date data at night. And I got them again today.
I see some differences.
When the most accurate bar data is present?

Thanks

@huseyin Typically, the bar data is ‘finalized’ at midnight ET for the day but it can at times be as late as 8:00 or 8:30 ET the following day. The reason is trade ‘corrections’ and late trades are constantly being received from the Securities Information Providers (SIP). The pre-market data is notoriously susceptible to updates.
