SymFlex Band - RSI-MAD Asymmetric

🔮 SymFlex Band – RSI-MAD Asymmetric Band by Kwang Il Lee
Source: surirang.com

The SymFlex Band is a unique asymmetric envelope built on a hybrid concept that fuses RSI momentum dynamics with MAD (Mean Absolute Deviation). Unlike traditional symmetric bands (like Bollinger Bands or Keltner Channels), this band expands and contracts asymmetrically, reflecting the directional momentum of the market.

🎯 Core Innovation
🔸 RSI-Based Asymmetry
This band is not centered merely on price volatility. Instead, it uses the RSI's deviation from the neutral line (50) to determine whether bullish or bearish pressure is dominating — dynamically expanding or compressing the upper/lower bands accordingly.

🔸 MAD-Weighted Scaling
To ensure the band responds accurately to real price deviation, MAD is used instead of standard deviation or ATR. It provides a more robust and median-sensitive envelope for noisy or volatile markets.

🔸 Dynamic Adaptation
The band is adaptive in both direction and width:

When RSI rises above 50, the upper band stretches wider.

When RSI falls below 50, the lower band stretches instead.

A minimum width threshold ensures stability.

📈 How to Use
Use breakouts from the band as potential trend signals.

Confirm market strength via table: Check if price is “In Range” or breaking out.

Monitor the correlation between MAD and RSI in the dynamic table to detect momentum sync.

🔍 Technical Notes
Supports multiple MA types (SMA, EMA, TEMA, DEMA, Zerolag, etc.) as the band basis.

Designed for both trend-following and range-trading interpretations.

Fully responsive to different market conditions through minimal user inputs.

🚨 Note: This is not a combination of unrelated indicators. The RSI-MAD structure is purpose-built to represent a new type of envelope based on directional momentum and deviation sensitivity.
