Actual high and chart high can it be different?

Here is the situation.
On May 28 expiry, I had kept an order to sell 19600CE and it got executed at 12.52pm @Rs.25. But if you see the chart high at 12.52 is less than Rs.10.
Is it normal? Why chart doesn’t show the actual high?

There are various ticks in one second and sometimes what happens is chart usually doesn’t capture all the ticks that’s why on some occasions actual high can be different than that printed on charts.

OK. Thank you.
