About

Williams VIX Fix panic-buy strategy: long when the VIX Fix formula (100×(highest-low)/highest) spikes above a percentile of its own recent highs.

Designed to mark capitulation spikes and mean-reversion entries.
Lower Percentile (e.g. 0.7) for more frequent signals.
Combine with an oversold RSI or volume spike for confirmation.
