An important concept for index traders that's often overlooked: how to read the VIX practically. The VIX (Volatility Index) measures the 30-day expected volatility of the S&P 500. **Practical VIX levels:** - VIX 10–15: Complacency. Often precedes sudden volatility events. - VIX 15–20: Normal. Trends are tradeable. - VIX 20–30: Elevated fear. Expect larger daily swings and more false breakouts. - VIX 30+: Panic. Huge intraday ranges. **How to use it:** - When VIX spikes above 25 and you're long indices, reduce size by 50% - When VIX is below 13, be cautious adding new longs — complacency often precedes corrections - VIX declining from a spike = "fear fading" = often a buy signal for indices Do you monitor the VIX in your index trading?
