Parabolic SAR in a Downtrend (Bearish):
In a downtrend, the SAR is calculated by subtracting from the previous SAR a value which is the product of the acceleration factor (AF) and the difference between the lowest price point (EP) in the current trend and the previous SAR.
Acceleration Factor (AF):
The AF starts…
