Delta

ലളിതമായ അർത്ഥം

Option delta is the modelled change in option value for a small change in the underlying, holding other inputs constant.

എന്തുകൊണ്ട് ഉപകാരപ്രദം

Delta 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-ൽ എവിടെ കാണാം

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

കണക്കാക്കുന്ന വിധം അല്ലെങ്കിൽ ഉറവിടം

XMarketRadar calculates Delta locally with Black-Scholes-Merton using spot, strike, years to expiry, NSE-published implied volatility and a fixed 7% risk-free-rate assumption. NSE supplies IV, not the Greek. The implementation has no dividend-yield input; theta is per day and vega per one volatility-percentage-point change.

ഇൻപുട്ടുകൾ, കാലയളവ്, യൂണിറ്റ്

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.

പ്രായോഗിക ഉദാഹരണം

Illustrative only: A call delta of 0.55 implies the model estimates about ₹0.55 option-value change for a small ₹1 underlying move, not a guaranteed ₹0.55 realized gain.

ഉയർന്നതും താഴ്ന്നതും

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

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

എപ്പോൾ ലഭ്യമല്ല

Unavailable (—) means Delta 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.

പരിമിതികളും സാധാരണ പിഴവുകളും

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.

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