Parabolic RSI: Applying Parabolic SAR to RSI for Reversal Signals

Summary

The Parabolic RSI adapts the Parabolic Stop and Reverse calculation to an RSI series instead of applying it to price. It tracks RSI extremes and updates a stop level using an acceleration factor that increases as the move extends, subject to a cap. A change in direction is signaled when RSI crosses that calculated level, giving a view of shifts in relative strength.

The described rules mark a bullish reversal when direction turns upward and the SAR value is at or below the oversold threshold; a bearish signal requires a downward turn with the SAR at or above the overbought threshold. The document supplies default RSI, threshold, and acceleration settings and explains that they can be adjusted. It presents the indicator as a source of potential entries and exits, but gives no backtest, comparative evidence, or performance data. Signals may therefore need testing across instruments and conditions, especially where indicator sensitivity can generate false reversals.

Key ideas

• The indicator computes a Parabolic SAR using RSI values rather than prices.
• Its acceleration factor rises when RSI reaches new directional extremes and is capped by a maximum.
• A bullish signal combines an upward direction change with an SAR value at or below the oversold threshold.
• A bearish signal combines a downward direction change with an SAR value at or above the overbought threshold.
• The document describes settings and signal logic but provides no backtest or performance evidence.
