Williams Vix Fix for Identifying Volatility Extremes at Market Tops and Bottoms

Summary

The Williams Vix Fix estimates panic or exuberance from price data, making it usable on instruments without their own volatility index. Its bottom mode measures the current low against the highest close in a recent window; a mirrored top mode measures the current high against the lowest close. Readings are flagged as extreme when they exceed either a Bollinger upper band calculated on the indicator or a threshold based on its recent range. An optional mode chooses which side to monitor according to price relative to a long trend average.

The document describes extreme readings as context for possible capitulation lows or upside exhaustion, and advises waiting for price confirmation rather than treating them as automatic trades. It also provides an additional filtered signal based on the end of an extreme reading and price-action conditions. No backtest or empirical performance evidence is presented, so the indicator’s predictive value is not established.

Key ideas

• The indicator derives volatility extremes from price rather than requiring a market volatility index.
• Bottom and top modes measure price dislocation in opposite directions relative to recent closes.
• Bollinger and recent-range thresholds identify unusually high indicator readings.
• The automatic mode selects the side to monitor based on price relative to a trend average.
• Extreme readings are context signals that require confirmation, and the document provides no performance validation.
