missing data and uncorrect historical data
-
Again I have Fetch data of HCL Tech to get 1 min data from 2021-01-14 09:15 to 2021-02-13 15:30.
There are some data is missing and When I compared with my previous 1 min data it is mismatching in that, Does it mean the data which angle one provides is not correct??
this is angle one data missing and wrong

@sujeetboran It is always recommended to verify the candle interval before saving in database or csv. You can try fetching data in batches and then can verify each batch before saving. In case of missing OHLCV, you can try to re-fetch the complete batch. Verification may add delay in processing but is always worth it.
