Price dint reach SL but position got squared off

[maddy_Des]

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?

I was long Banknifty at 14900 and had placed a stoploss at14812. The stop loss got executed, but when I look at the chart be it on NEST, NSE, Yahoo or anywhere else, I don’t see that price of 14812. How is this possible? Is it a problem with the platform?
