calcGreeks computes and reports the fair price value and numerous Greek values for vanilla European options, using the Black-Scholes-Merton model, optimized for performance.

No toolbox is required - only basic Matlab.

Any input parameter can be vectorized (examples below). Note that only one parameter can be vectorized (any parameter that you choose).

calcGreeks is used by the IQFeed-Matlab connector (IQML) - https://undocumentedmatlab.com/IQML

Syntax:
[fairValue, greeks] = calcGreeks(spot, strike, rate, yield, volatility, maturity, putCallInd, annualFactor)

Inputs:
- spot - (mandatory) Underlying asset's spot price
- strike - (mandatory) Derivative contract's strike price
- rate - (default: 0) Domestic risk-free interest rate (%)
- yield - (default: 0) Foreign interest rate (Forex) or dividend yield (stock)
- volatility - (default: 0.3) Historic volatility of the underlying asset's price
- maturity - (default: 1.0) Number of years until the option contract expires
- putCallInd - (default: 'Call') Either 1 (Call), -1 (Put), or [1,-1] (both), or as strings. For example: "Call", 'put', 'cp', {'Call',"put"} etc.
- annualFactor - (default: 1) Used to de-annualize Theta, Charm, Veta, Color. Typical values: 1 (report annualized values), 365 (report 1-calendar-day estimates), or 252 (report 1-trading-day estimates)

Usage examples:

% Example 1: vectorized call/put
>> [fairValue, greeks] = calcGreeks(56.8, 60, 5, 2.5, 35, 15/365, {'call',"put"}, 365)
fairValue =
0.5348 3.6700
