    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??

    @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.
