Calculation Methods తేడా 🧮

VIX Calculation:

Input: Multiple Nifty options (calls & puts)
Method: Weighted average of option IVs
Output: Single market volatility number
Formula: Complex mathematical model

VIX = √(Σ weighted option contributions)

IV Calculation:

Input: Individual option price
Method: Black-Scholes reverse calculation
Output: Option-specific volatility
Formula: Market price → implied volatility

Black-Scholes: Option Price = f(S,K,T,r,IV)
Given Price, solve for IV

Trading Applications వ్యత్యాసం 📊

VIX-based Trading:

Purpose: Market timing decisions
Strategy: Portfolio allocation based on VIX
Implementation: Asset allocation changes

Example:
VIX > 25: Increase equity allocation (oversold)
VIX < 15: Reduce equity allocation (complacent)

IV-based Trading:

Purpose: Option strategy selection
Strategy: Buy low IV, sell high IV options
Implementation: Strike-specific decisions

Example:
20,000 Call IV = 14% (Low): Buy this call
22,000 Call IV = 22% (High): Sell this call

19,000 Put IV: 15%
20,000 Put IV: 16% 
21,000 ATM IV: 16% (≈ VIX)
22,000 Call IV: 17%
23,000 Call IV: 19%

VIX Impact on IV Smile:
