This is a modified conversion of the RMA ATR Bands which is a directional volatility trend indicator built around a smoothed RMA baseline combined with asymmetric ATR expansion bands.

Unlike traditional symmetric ATR envelopes, the indicator uses independent upper and lower ATR multipliers to create adaptive directional filtering and trend regime detection. This allows the system to respond differently to bullish and bearish volatility conditions while maintaining a smoother baseline structure through RMA smoothing.

Bullish regime:
• Price closes above the upper ATR expansion band

Bearish regime:
• Price closes below the lower ATR expansion band

I added and modified the upper and lower bands along with dots for extreme conditions.

This is a modified conversion of the RMA ATR Bands which is a directional volatility trend indicator built around a smoothed RMA baseline combined with asymmetric ATR expansion bands.

Unlike traditional symmetric ATR envelopes, the indicator uses independent upper and lower ATR multipliers to create adaptive directional filtering and trend regime detection. This allows the system to respond differently to bullish and bearish volatility conditions while maintaining a smoother baseline structure through RMA smoothing.

Bullish regime:
• Price closes above the upper ATR expansion band

Bearish regime:
• Price closes below the lower ATR expansion band

I added and modified the upper and lower bands along with dots for extreme conditions.
