Order execution related

Hi all, so yesterday i.e 30th June I tried to short KOTAKBANK, I placed an order at 1836.1/1836.15 around 10:41 AM. My SL order is at 1839.15/1839.2. I heard a pop notification stating that the SL is hit at 10:51 AM. But when I see the candle at that time, it didn’t even reach the 1839 level, the high of that candle is 1838.35. The 1839 level was later reached around 11:40 AM. I have checked other platforms like upstox, tradingview to check if the issue is with zerodha but the same thing is observed in upstox and tradingview as well. Can someone explain how this happened and whether this is common or not??
I am attaching the images here pls check


The price of your stoploss order will sometimes not show on the charts due to the unavailability of tick by tick data. This post explains it in detail: I placed a stop loss order which got executed, but I don't see my stop loss price on any charts be it on NEST, NSE, Amibroker or any other chart?

Thanks @ShubhS9. Does this occur often ? should one be worried about this?
