Williams VIX Fix Advanced
Synthetic fear gauge (Williams VIX Fix) with dual-direction signals, StdDev and percentile spike bands, stall/absorption context, slow-WVF trend context, divergence wedge, and gradient coloring on a 0–100 bounded panel.
Features
- Bullish WVF core —
(Highest(Close, N) − Low) / Highest(Close, N) × 100: measures how far below the recent high the current low is — high values = fear / potential bottom - Bearish WVF —
(High − Lowest(Close, N)) / Lowest(Close, N) × 100: mirror for top detection (complacency spike) - Dual spike bands — StdDev upper band and percentile threshold; spike detected when WVF crosses either (both toggleable)
- Stall/absorption — when WVF surges but price barely moves (thin wick, not genuine fear), the signal is marked as absorbed/weak; computed independently for the bullish and bearish side
- Spike Quality (0–100) — how far a spike pushed past its own StdDev band and context EMA, penalized when stall/absorption is active
- Reclaim — marks the bar where price reclaims the recent range within N bars of a non-absorbed spike; the actionable signal, versus the spike itself which only flags an extreme
- Context line (D-line) — EMA of the fast WVF; acts as a signal line showing the smoothed fear baseline
- Divergence wedge — fills the gap between fast WVF and the context EMA when they move in opposite directions
- View Mode — Clean / Balanced / Full controls how many layers show at once (Clean: core lines + Reclaim + Sentiment Bar; Balanced: + Context/Bands; Full: + Percentile/Fills/Divergence)
- Gradient coloring — calm (cyan) → fear (pink) between configurable Normal Fear and Elevated Fear levels
- Shadow fills — fear shadow above midline, calm shadow below
- Pluggable smoothing — EMA, SMA, RMA, WMA, SuperSmoother, T3, KAMA, JMA Approx (optional, default off)
- Sentiment bar — live ±100 bull/bear dominance score with a mini bar on the right edge of the panel:
(WVF ÷ its StdDev band − Bear-WVF ÷ its StdDev band) × 100. A graded readout, not a fixed Bullish/Bearish claim - Alerts — Bull Spike, Bear Spike, absorbed variants, and Reclaim Long/Short, all bar-close gated
Scoring
This indicator has no score — it is a pure volatility/fear gauge. Spikes indicate potential exhaustion (fear extremes); they are context signals, not directional triggers.
Bands
| Band | Purpose |
|---|---|
| StdDev Upper Band | SMA(WVF, bbl) + mult × StdDev(WVF, bbl) — dynamic spike threshold |
| Percentile Level | lowest + rangeHigh% × (highest − lowest) over rangeLen bars — percentile baseline |
A spike fires when WVF crosses either band (individual toggles, OR logic). Default: StdDev band only (2σ) — this is the more selective threshold and works across all timeframes. The percentile threshold adapts to the distribution but can fire too often on sub-daily or low-volatility instruments where all WVF values are inherently small.
Stall / Absorption
When WVF − WVF[N] > stallWVFMin AND |price change over N bars| < stallFlatATR × ATR, the spike is marked as absorbed. This catches thin wicks that trigger the fear gauge mechanically without genuine price pressure behind them. The bearish side uses its own Bear-WVF − Bear-WVF[N] change against the same price-flatness check, so a bull-side stall never suppresses a bear spike or vice versa.
Spike Quality
quality = min(100, spikeExcess × 50 + ctxExcess × 25 + (stall ? 0 : 25)), where spikeExcess = max(0, WVF / band − 1) and ctxExcess = max(0, WVF / contextEMA − 1) (mirrored for the bearish side). The quality of the most recent spike is captured and carried into the Reclaim label.
Reclaim
Within Spike Recency Window bars of a non-absorbed spike (spikeStrong/bSpikeStrong), a Reclaim fires the first bar close breaks back above the prior Reclaim Confirmation Length-bar high (long) or below the prior low (short). Min Spike Quality for Reclaim (default 0 = disabled) can require the originating spike to have scored above a threshold before the reclaim is marked.
