Relative Strength Volatility Variable Bands

The Relative Strength Volatility Variable Bands indicator provides an adaptive trend-following framework that adjusts its sensitivity based on RSI-derived volatility to identify dynamic support and resistance levels.

Usage

The Usage section describes how the script can be used to identify trend direction and potential reversal zones. The core of the indicator is the adaptive midline, which changes color based on the prevailing trend (green for bullish, red for bearish).

• Trend Following: Traders can look for price action relative to the midline. When the midline is green and the price is above it, the trend is considered bullish. Conversely, a red midline with price action below it indicates a bearish trend.
• Volatility Bands: The tool plots five levels above and below the midline. These bands expand and contract based on volatility, serving as dynamic overbought and oversold zones or potential targets for trend extensions.
• Bar Coloring: The script includes custom bar colors that reflect both the midline trend and immediate price momentum, helping users quickly identify strength or weakness within a trend.
• Alerts: Built-in alerts notify users when price crosses the midline or when the midline trend direction changes.

Details

This study combines concepts from Giorgos Siligardos's Reverse Engineering RSI and Tushar S. Chande's Variable Moving Average (VMA). The construction follows a multi-step process:

1. Volatility Index: It first calculates the price levels required for the RSI to reach 70 and 30. The difference between these levels is normalized to create a bespoke volatility index.
2. Adaptive VMA: This volatility index is used to modulate the sampling length of an exponential moving average, creating an initial VMA that speeds up during high volatility and slows down during low volatility.
3. Band Construction: Upper and lower VMAs are calculated based on prices specifically above and below the initial VMA. The midline is the median of these two values.
4. Multi-Level Expansion: The final bands are created by projecting multiples (1 through 5) of the distance between the midline and the upper/lower VMAs.

Settings

• Source: Determines the price data used for all calculations (e.g., Close, Open, HL2).
• VMA Period: Sets the base length for the Variable Moving Average calculation.
• Volatility Period: Adjusts the lookback window used for the reverse-engineered RSI levels and volatility normalization.

FAQ

How do I access Relative Strength Volatility Variable Bands?

You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.

What do the different band levels represent?

The levels act as standard deviation-like multipliers. Level 1 is the most immediate reaction zone, while Level 5 represents extreme price extensions relative to the current volatility.

Why does the midline change color?

The midline color is a trend bias indicator. It turns green when the midline is sloping upwards and red when it is sloping downwards, helping to filter trade direction.
