Using a Volatility Rank to Distinguish Trend and Choppy Regimes

Summary

The Volatility Switch indicator ranks recent realized volatility against its own recent history and scales the result from zero to one. In the supplied version, volatility is estimated from normalized price changes over a rolling period, then the current estimate is compared with prior estimates to form a relative rank. The midpoint, 0.5, separates readings that indicate volatility is relatively elevated from those that indicate it is easing.

The suggested interpretation is that readings above the midpoint warn of a high-volatility, potentially choppy market, where RSI overbought or oversold levels may help frame trades. A decline below the midpoint after higher readings is presented as a possible sign of trend formation. This is a regime filter rather than a fully specified entry, exit, or risk-management system. The page gives no backtest, market examples, or evidence that either regime interpretation predicts returns, so the threshold and lookback should be validated for the instrument and timeframe being traded.

Key ideas

• The indicator compares current realized volatility with its recent history and expresses the result on a zero-to-one scale.
• Readings above the midpoint are described as a high-volatility regime that may be choppy.
• A drop below the midpoint after elevated readings is suggested as a possible trend-formation signal.
• The suggested use of RSI in choppy conditions does not define complete trade rules.
• The document provides no backtest evidence, so the regime interpretation requires validation.
