India VIX is the fear gauge for Nifty. Absolute level matters less than regime: the z-score versus a 60-day mean tells you if volatility is calm (z below minus one), normal (minus one to one), or stressed (above two).
Models trained in calm regimes fail in stressed ones. The filter blocks new entries when VIX z exceeds two (crowd panic, gap risk) and when VIX z is below minus 1.5 with a shrinking range (complacency). Feature vix_india equals (VIX minus mean60) divided by std60. The goal is not to predict VIX but to know which regime your model was trained for.
Q: What is a good VIX z-score to trade?
A: Between about minus one and plus one is normal; beyond plus two or below minus 1.5 the filter steps aside.
Q: Why block trades in high VIX?
A: Extreme VIX means gap risk and crowd panic; models calibrated on calm data mislead.
Q: Is VIX a directional signal?
A: No — it is a regime context dial, used to gate entries, not to predict direction.
Q: How is vix_india computed?
A: As a 60-day z-score of India VIX: (current minus mean) divided by standard deviation.
