I'm facing problems in backtesting my strategies due to gaps in historical data. I have checked the Zerodha charts also and the same mismatch exists. Let me give some examples here:
1) ACC - data missing for candle at 2020-11-02 15:12:00+05:30 (1min interval)
Historical download screenshot
Same missing on charts also 15:11:00 candle
2.) PFC - found missing data (5 min candle) from 2015-12-22 10:20:00+05:30 to 2015-12-22 10:45:00+05:30 (highlighted potion) in all scripts downloaded (PFC shown here). In 1 min data is available upto 10:22 & then from 10:47 only.
Same missing on charts also
5 min charts 22-12-15 10:20 candle
22-12-15 10:45 candle
Please see and help in resolving the problem. I'm having difficulty in backtesting my strategy.
