In a uptrend stop losses are often placed just below the higher low. The problem is we don't know whether the current pullback has formed a higher low or whether the pullback will continue.
This script places a yellow dot below the current candle at the stop loss level only when the higher low has been confirmed, allowing you to place your new stop loss at the earliest possible time.
Works in the opposite way when shorting the pair.
My trend analysis is based on significant swings requiring two candles either side of the low/high that confirm the swing. You can change this if you like.
