Volatility Switch Indicator

The Volatility Switch Indicator tool estimates current volatility relative to historical data to help traders determine whether the market is in a trending phase or a mean-reversion (choppy) phase.

Usage

The indicator oscillates between 0 and 1, with the 0.5 level acting as the primary threshold for determining the market regime:

• Trending Regime: When the Volatility Switch falls below the 0.5 level, it suggests that volatility is decreasing or stable, which is often a sign of trend formation. Traders may look for trend-following opportunities in this environment.
• Mean Reversion Regime: When the indicator rises above the 0.5 level, it indicates that current volatility is high relative to the past. This often leads to "choppy" price action or abrupt moves. In this environment, traders might favor mean-reversion strategies or use oscillators like the RSI to identify overbought/oversold levels.

Details

The Volatility Switch (VOLSWITCH) was introduced by Ron McEwan in Technical Analysis of Stocks & Commodities (Feb 2013). The calculation involves:

1. Calculating the daily rate of change (ROC) of price normalized by a simple moving average.
2. Calculating the Standard Deviation of this value over a specific lookback period.
3. Determining the "switch" value by comparing the current standard deviation against its historical values within the lookback window.

This implementation allows users to toggle between two standard lengths (14 and 21) to observe short-term and medium-term volatility shifts.

Settings

• Show Length 21: Toggles the visibility of the 21-period Volatility Switch line.
• Show Length 14: Toggles the visibility of the 14-period Volatility Switch line.

FAQ

How do I interpret the 0.5 level?

Values below 0.5 suggest a low-volatility environment conducive to trending, while values above 0.5 suggest a high-volatility environment where price action is likely to be range-bound or erratic.

Can I use both lengths simultaneously?

Yes, you can enable both the 14 and 21 lengths in the settings to see how different lookback periods confirm volatility shifts.
