Implied volatility

सरल भाषा में अर्थ

Implied volatility is the volatility input that makes an option-pricing model match a stated option price.

यह उपयोगी क्यों है

Implied volatility 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.

XMarketRadar में कहाँ दिखता है

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

गणना या स्रोत

Solve the selected option-pricing model for the volatility input that reproduces the observed option price using spot, strike, time, rates and other required inputs.

इनपुट, अवधि और इकाई

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.

व्यावहारिक उदाहरण

Illustrative only: If an option trades at ₹12, the model may require 24% annualized volatility to reproduce ₹12 with the stated spot, strike, time and rate; changing those inputs changes IV.

ऊँचे और नीचे का अर्थ

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

धनात्मक, ऋणात्मक और वास्तविक शून्य

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

यह कब अनुपलब्ध है

Unavailable (—) means Implied volatility 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.

सीमाएँ और सामान्य गलतियाँ

Greeks and IV are model estimates, not guaranteed realized changes. XMarketRadar's Black-Scholes-Merton calculation assumes a fixed 7% risk-free rate and has no dividend-yield input; exercise style, carry, stale quotes or a different rate can materially change the result.

बाजार-विशिष्ट अंतर

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