Is my order execution is guaranteed in case of Smart order trigger?

The Market Protection Percentage (MPP) smartly executes the triggered GTT stop-loss order at the best available market price.

Once your stop-loss leg gets triggered, a limit order is placed at 3% (considering MPP is set as 3%) of the trigger price. The order will be executed at the next best available bid or offer within 3% of the trigger price, provided enough depth is available.
