Missing Data

[sujeetboran]

I Have ran a query to get data for HDFC bank. From 2021-01-14 09:15 to 2021-02-13 15:30. which is 1 min candle data I saw multiple data is missing
2021-01-19T09:45:00+05:30,735.55,735.55,733.5,734.28,154056
2021-01-19T09:46:00+05:30,734.13,735.03,734.13,734.88,43096
2021-01-19T09:57:00+05:30,737.45,737.5,736.5,736.83,440126
2021-01-19T09:58:00+05:30,736.85,737.63,736.63,737.28,55804

it is highly impossible that HDFC bank is not got traded for straight 10 min from 46-57 min.
Is it correct data?? or am i missing something??
