About VolatilityGyan

A permanent reference library on volatility — built to be understood, not followed.

Our mission

Volatility is the least-understood word in trading, partly because it is nine different quantities wearing one name. VolatilityGyan exists to take those quantities apart and explain each one properly: what it measures, what it is computed from, the formula with every symbol defined, where it is genuinely useful, and the precise conditions under which it stops being true. We document 68 concepts across 8 sections, 68 of them with a full formula, 10 client-side calculators and 106 glossary terms.

What makes this different

  • A reference, not a blog. Nothing here is dated commentary. Every page is written to be as true in five years as it is today. There are no posts, no news and no market calls.
  • The diagrams are computed, not drawn. Every smile, skew, surface, term structure and regime chart on this site is inline SVG generated at build time by the site's own Black–Scholes and statistics engine. The illustrative series come from a seeded generator, so the build is byte-reproducible.
  • The calculators share that engine. The browser tools call the identical functions the build called, so a tool here cannot disagree with a page here.
  • Limitations before applications. Every page has a section on where the concept breaks down, because a measure you cannot criticise is a measure you cannot use.
  • India-specific. Worked examples use NIFTY and BANKNIFTY, Indian lot sizes, India VIX, and the Indian event calendar — RBI policy, the Union Budget, election counting days.

What we will never do

We will never say implied volatility is high and therefore options should be sold. We will never publish a trade call, a target, a stop-loss, a win rate or a backtest. We will never claim any strategy on this site is profitable. Volatility analysis tells you what the market is charging for uncertainty; it does not tell you whether that price is wrong, and it never tells you what to do about it.

Who it is for

Retail traders who keep reading "IV crush" and want to know what actually happens; options traders who need the skew and the term structure straight; quantitative traders and risk managers who want a clean, internally consistent reference; and derivatives students who need the mathematics explained rather than asserted. Start with What is Volatility?, or jump to the cheat sheet.

What we are not

VolatilityGyan is an educational platform only. We are not a SEBI-registered investment adviser, research analyst or stockbroker, we do not manage money, and we never give buy or sell recommendations. See our SEBI Disclaimer and Editorial Policy.
