Why there is a high-low difference between Daily & Intraday charts?

Sometimes when we see daily chart & intraday chart of same instrument for same day, there is a considerable difference in High / Low point between them. This lack of accuracy on data side disturbs intraday analysis & back-testing results. One such instance was recently observed in Bank Nifty December Future contract on 20/12/19. Where day high as per NSE & Daily candle in Kite is 32440 where as intraday high was seen up to 32412.90 only. Snapshot is attached for your ref. Request you to take this thing in priority with your tech team and do confirm earliest once resolved.

Can check this, explained there.

Thanks…!!
