Vix Fix Linear Regression Signals for Market Bottoms

Summary

This strategy combines the Williams Vix Fix, which estimates unusually high downside volatility, with a linear regression of that measure. A green regression histogram as it turns upward, together with a green Vix Fix reading, signals a long entry. A red histogram indicates declining regression values and is described as an exit cue, though the supplied implementation makes that exit conditional on a separate setting. It also uses an ATR-based stop and an initial low-price stop rule.

The document explains the signal logic and lists configurable indicator and stop parameters, but provides no reported performance results beyond a short Bitcoin futures backtest configuration. It cautions that the method targets broad market lows rather than individual stocks, that regression cannot eliminate false signals, and that parameters may need adjustment across changing conditions. The strategy is therefore a heuristic for studying potential bottoms, not evidence of reliable turning-point prediction.

Key ideas

• Williams Vix Fix readings are regressed to help identify changes in downside-volatility conditions.
• A rising regression histogram combined with a high Vix Fix state triggers long entries.
• The strategy uses ATR and recent lows in its stop logic.
• The described sell cue and the implemented exit behavior differ because indicator-based closing is conditional on a setting.
• False signals and market-specific parameter sensitivity remain limitations.
