How to read it. Mark IV is the implied volatility behind each exchange's option mark price. The smile uses the out-of-the-money option at each strike (puts below the forward, calls above); on the delta axis 0.25 is the 25-delta put, 0.5 at the money and 0.75 the 25-delta call. ATM IV is interpolated at the forward. The 30-day figures interpolate between the expiries either side of 30 days. Realized vol is the 30-day standard deviation of daily log returns of the Binance USDT perp, annualized with √365, as on the volatility screener.

Solana implied volatility FAQ

What is Solana implied volatility?

Implied volatility (IV) is the annualized volatility that makes an option's model price match its market price. It is the market's price for future movement, not a forecast. On this page it is each exchange's mark IV, the volatility behind its mark price.

What is 25-delta skew (the risk reversal)?

The 25-delta risk reversal (RR25) is the implied vol of the 25-delta call minus that of the 25-delta put. Negative means puts are bid: traders pay more for downside protection than for upside. Put skew is the same number with the opposite sign. The 30-day series interpolates between listed expiries in total variance.

Why is implied volatility different from realized volatility?

Realized vol measures how much the price actually moved (here the 30-day standard deviation of daily log returns, annualized with √365, as on the volatility screener). Implied vol is what options charge for the next 30 days. IV above RV means options are rich relative to recent moves; below means they are cheap. Nothing here is financial advice.

Which exchanges are covered?

Bybit options only, from their public market-data APIs, recorded every 5 minutes. That is not the whole crypto options market, so these IVs can differ from volatility indices built on other venues.
