Delta (options)

Sun, 21 Jun 2026 00:00:00 +0000

Delta is the first-order option Greek that measures how much an option’s premium changes for a one-rupee change in the price of the underlying, holding time, volatility and interest rates constant. Computed from the Black-Scholes-Merton model that Zerodha Kite uses for its Greeks display, call delta ranges from 0 to +1 and put delta from 0 to -1, and the absolute value doubles as the option’s approximate probability of expiring in-the-money. It is the Greek that quantifies directional exposure.

Strike selection on the option chain

Strike selection is the choice of which option strike to trade, made by weighing the strike’s delta and its implied probability of expiring in-the-money, its liquidity as shown by open interest and volume, the risk-reward of the position, and the tradeoff between in-the-money, at-the-money and out-of-the-money moneyness . On Zerodha it is done by reading the Kite option chain, which lists every listed strike with its open interest, volume, implied volatility and, in the Greeks tab, its delta and the other Greeks. The strike a trader picks fixes the cost, the leverage, the probability of profit and the risk profile of the whole position.

Option Greeks are sensitivity measures that quantify how an option’s price changes in response to changes in the underlying price, time, implied volatility, and interest rates. Kite displays Greeks in its options chain Greek tab; Sensibull shows net Greeks for multi-leg strategies. This guide explains how to find and interpret each Greek and how to use them to make better trade decisions.
