SENSEX Vega Analysis | Live Call & Put Vega
Vega Analysis for SENSEX plots total Call Vega and total Put Vega across a band of strikes around the money. For every minute it solves implied volatility from each option's traded price, reads the vega, and sums the calls into one line and the puts into another — so you can see how SENSEX volatility exposure builds and unwinds through the session.
Because each SENSEX call and put trades at its own implied volatility, the two vega lines diverge with the skew. A put-vega line above call-vega reflects downside-fear skew; call-vega leading points to upside-volatility demand. Live mode streams every selected SENSEX strike in real time.

BSE Sensex (SENSEX) Vega: Why Calls and Puts Diverge
Shouldn't a call and put have the same vega?
In the textbook Black-Scholes model, a call and a put at the same strike and the same implied volatility have identical vega. In the live SENSEX market they do not, because the call and put at a strike trade at different implied volatilities — the volatility skew. Vega is derived from each option's own market price, so the call-side and put-side vega lines for BSE Sensex separate exactly to the degree the skew is present.
What a widening gap tells you on SENSEX
When put vega pulls away from call vega, demand for downside protection is bidding up put implied volatility — a defensive, risk-off tone. When call vega leads, upside-volatility demand is dominating, which can accompany momentum or short-covering. Tracking the gap intraday on BSE Sensex gives an early, price-independent read on positioning.
Combining vega with skew tools
Pair Vega Analysis with the Volatility Skew and IV Chart views for SENSEX. Skew shows the IV shape across strikes at a moment; Vega Analysis shows how the aggregate call/put volatility exposure built up and unwound through the session. Together they explain both the level and the time dynamics of BSE Sensex volatility.
BSE Sensex (SENSEX) Vega Analysis: Live and Historical Modes

Putting it to work
