Acceleration Factor vs Trailing Stop

A multiplier in the Parabolic SAR indicator that increases the rate at which the trailing stop accelerates toward price, starting at 0.02 and typically capping at 0.20, controlling how aggressively stops move as trends strengthen.

A dynamic stop-loss that automatically moves in the direction of a profitable trade as price advances, locking in accumulated gains while allowing the position to continue benefiting from ongoing price movement.
