Definition
India VIX is a volatility index published by NSE that estimates expected 30-day volatility on NIFTY, derived from NIFTY options prices. High VIX = market expects turbulence. Low VIX = market expects calm.
Range
Historically, India VIX ranges roughly 10–35 in typical regimes. Below 12 signals complacency. Above 20 signals stress. Above 30 is usually a crisis print.
How it's used
Options sellers love high VIX (richer premiums). Options buyers prefer low VIX (cheaper premiums). Directional traders use VIX rises as a warning signal for stop tightening. The Sleeping Trade engine uses VIX as an input into position sizing and strategy selection.
Limitations
VIX is a forward-looking estimate, not a forecast. Markets can have low VIX and still crash (volatility expansion happens quickly). VIX is a context indicator, not a standalone signal.
