I have been trying to download the Minute candles, however it looks like data is missing for 23rd September 2019. its only returning 361 candles and missing data from 3:15 to 3:29. I tried for Hindalco, Bajaj Finance. Issue seems to be there for pretty much every stock . If there was an issue with you systems during that time, why didn't you guys backfill it ?
We are checking on this.
