Historical data API

Sometimes SL are hit beyond the candle high. But the historical data API also do not capture such high.
For e.g.
Data: 14-Nov-2022
Instrument: BANKNIFTY 17th w NOV 42400 CE
Execution time: 9:19:16
Execution price: 207.8
Candle high: 201.7

This creates big difference in backtesting the strategy. Is there any way out.
