Why was the stop-loss order executed even though the price did not breach the trigger?

In some instances, the stop loss order might activate even if the trigger price doesn’t appear to be reached on the charts. This discrepancy is attributed to the constraints of trading and charting platforms, which usually show only one transaction (buy/sell) per second on the chart. It’s important to note that within that one second, multiple transactions may occur. As a result, the execution of the stop loss or limit price could happen within a tick that isn’t visible on the chart, irrespective of the platform being used. To confirm executed trades, verification can be done directly on the exchange.
