Option Greeks overview

Plain-language meaning

Option Greeks measure the sensitivity of option prices to underlying price, volatility, time decay and interest rates.

Why it is useful

Option Greeks overview is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.

Where it appears in XMarketRadar

Look for Option Greeks overview in Futures, Option Chain, Options Screener and derivative study tables for a selected underlying and contract.

How it is calculated or sourced

First- and second-order partial derivatives of option price: Delta = ∂V/∂S, Gamma = ∂²V/∂S², Theta = −∂V/∂t, Vega = ∂V/∂σ, Rho = ∂V/∂r under Black-Scholes-Merton. XMarketRadar computes Delta, Gamma, Theta and Vega assuming a fixed 7% risk-free rate.

Inputs, period and unit

Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.

Worked example

Illustrative only: With an at-the-money call option priced at ₹25 with spot at ₹500, Delta = 0.50, Gamma = 0.02, Theta = −₹1.20/day, and Vega = ₹0.80 per 1% IV. If spot moves to ₹501, estimated price is ₹25.50; if one day elapses with no spot or IV change, estimated value is ₹23.80.

What high and low mean

A higher or lower Option Greeks overview value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

Positive, negative and genuine zero

Positive and negative Option Greeks overview values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

When it is unavailable

Unavailable (—) means Option Greeks overview is absent, unsupported, stale under the screen's rules or not computable from verified inputs. It must never be converted to zero or a neutral signal.

Limitations and common mistakes

Option Greeks overview may differ by provider definition, observation time, instrument and venue. Common mistakes are dropping units or dates, comparing unlike scopes, and treating a missing value as zero.

Market-specific differences

Contract size, exercise style, expiry, settlement, price unit and trading rules vary across all supported markets. Always use the selected contract specification.
