[DEM] Parabolic SAR Moving Average (PSARMA)

[DEM] Parabolic SAR Moving Average is a smoothed trend-following indicator that applies a moving average filter to traditional Parabolic SAR values to create a more stable directional signal with reduced whipsaws. The indicator calculates standard Parabolic SAR using customizable acceleration parameters (start, increment, and maximum values), then applies a 200-period RMA smoothing to eliminate the frequent reversals that can occur with raw SAR signals in sideways or volatile markets. This smoothed approach transforms the typically jagged SAR plot into a flowing yellow line that better represents the underlying trend direction while maintaining the SAR's inherent ability to accelerate during strong trending moves. The result is a hybrid indicator that combines the trend-following characteristics of moving averages with the acceleration-based logic of Parabolic SAR, making it particularly useful for identifying major trend changes and providing cleaner entry and exit signals in trending markets.
