That’s the ATR value at that swing low (yellow line).
One trade idea is having The bull entry at 1 ATR.
The stop is 3 ATR.
The target is 3 times the stop.
I don’t use stops - I watch them for my stop hunt.
The idea there is...since the average true range is quite high, in order for price to hit the bull stop, it has to be more volatile than the current ATR number.
