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.
