Option Vega
Vega is how much an option's premium changes when implied volatility moves by one point. A vega of 9 on a NIFTY option means about ₹585 per lot for every one-point rise in IV.
Volatility moves premiums too
An option can lose money even when the underlying moves your way, if implied volatility falls enough. Around results, budgets and RBI meetings, IV often rises before the event and drops right after it (the IV crush).
Which options have the most vega
Vega is largest for at-the-money options with more time to expiry. Weekly options close to expiry carry little vega and a lot of gamma; monthly options carry more vega.
Long and short vega
Option buyers are long vega and gain when IV rises; sellers are short vega. A calendar spread is a way to be long vega while keeping time decay in your favour.

What if…
What-if values and the chart use the Black-76 model on the future (rate as set, calendar days), so they can differ slightly from the app's live Greeks.
