Question 1

What is implied volatility (IV) and why does it matter for options traders?

Accepted Answer

Implied volatility is the market's expectation of future price movement, derived from current option prices. High IV means the market expects large moves — options are expensive. Low IV means the market expects calm — options are cheap. For option sellers, high IV means more premium collected. For option buyers, low IV means lower entry cost. Trading without reading IV is trading blind on whether the price you're paying is fair.

Question 2

What does the volatility smile (Vol Curve) tell me?

Accepted Answer

The Vol Curve shows how IV is distributed across all strikes for a given expiry. The classic 'smile' shape means OTM options on both sides have higher IV than ATM. In Indian index options, you typically see a 'skew' — OTM puts have significantly higher IV than OTM calls, reflecting the market's tendency to price in downside risk more aggressively than upside. Identifying which strikes are richly priced helps you decide where to sell or hedge.

Question 3

How do I use the IV Term Structure for calendar spreads?

Accepted Answer

Look for expiries where near-term IV is significantly higher than far-term IV — a steep downward-sloping term structure. This creates a calendar spread opportunity: sell the near-expiry option (high IV, higher premium) and buy the far-expiry option (lower IV, cheaper premium). The position profits when near-expiry IV collapses after an event while far-expiry IV remains stable.

Question 4

What is IV skew and how do I interpret positive vs negative skew?

Accepted Answer

IV skew is the difference between put IV and call IV at equidistant strikes from ATM. Positive skew means puts are more expensive than calls — the market is pricing in downside risk (bearish hedging). Negative skew means calls are more expensive — bullish positioning or speculation. Use the Live Skew chart to track how this sentiment shifts during the session, especially around news events.

Question 5

When is the best time to sell options based on IV Charts?

Accepted Answer

The best time to sell options is when ATM IV is elevated relative to its recent range — not at its session low. Use the Live ATM IV chart to see where IV is in its intraday range. If IV has been expanding all morning into an event, wait for the event to pass and the crush to begin before closing. If IV is near a session or weekly high, that is generally a better entry for premium sellers.

Question 6

Which indices and segments does IV Charts support?

Accepted Answer

IV Charts works for all major indices on NSE and BSE — Nifty 50, BankNifty, FinNifty, MidcapNifty, Sensex, Bankex — and MCX commodity underlyings. Select your index, segment, and exchange in the widget header. All four tabs update in real time for the selected underlying.
