If you’re into Options trading, you understand the vital role played by ‘Option Greeks.’ According to Investopedia, trading options without grasping the Greeks is like flying a plane without reading its instruments. Option Greeks, represented by Greek alphabets, determine how option prices change with factors like time, volatility, and the underlying stock price.

These Greeks are computed using the Black and Scholes options pricing model, named after its creators Fisher Black and Myron Scholes, dating back to 1973. In this article, we’ll explore an Option Greeks Calculator that provides real-time updates and calculates Greek values for all option strike prices traded on NSE.
