Trading Hours in Historical Data

I was wondering in the historical data of a min bar chart from AAPL.
I get trading hours from 9:00-24:00+.
What is that exactly?
Trading time is from 09:30 - 16:00 everything before and beyond is trading data from IEX alone ? or from SEC ?
I know pre market and After Hours but until 24:00 it appears to be a very special feature for the historical data.

I am not able to find any information about that.


Hi Alpaca3000

Where did you find that information?

On the Alpaca Dashboard or TradingView?


the information are stored in the alpaca database which contains historical data to a specific ticker symbol like AAPL.

This is the link to the documentation.

in this data I get datapoints form 09:00 to 24:00:00 o’clock.

So where did the additional data came from ?

The Trading Hours are from 09:30 till 16:00

A shown on this page Alpaca Introduces Stock Trading from 4 am to 8 pm ET
