Data Retrieval Using LSEG Python Data Library Giving Null Values for OHLCV data

HemagGor

I am retrieving ohlcv data using lseg data library python. I have data from 1st jan 2025, I want to run query every day and just append the last trading day data. I have code for that, but when I am running it on 15-20 stocks then it appends data for some stocks but gives null values for other stocks for last trading data. what is the issue here? Why I am getting nan values for ohlcv data for some of the stocks

Thank you for reaching out to us.

To my understanding, historical data is released according to specific schedules and may not be available immediately after the market closes.

For instance, if the data becomes accessible a few hours later or the following day, this delay is typically due to the designated release times for historical data.
