Why was my SL order executed even though the price did not breach my trigger?

There are a few potential reasons for this:

1. Market volatility: If the market was particularly volatile when your order was executed, the price may have briefly touched or passed your trigger price, even if it quickly rebounded.

2. Slippage: If your broker couldn't find a buyer or seller at your specified price, they may have executed the order at a slightly different price.
