Introduction

Option Pricing Engine using Black Scholes model

The project consists of a simple rest API to price options contracts using the Black Scholes model. The pricing model was built with certain assumption. Including constant market data, rates and volatility.

  • Works only for European options
  • With no dividend pay off
  • With no markups charges included
  • With each contract of 100 units
  • With a constant interest rate
  • With a constant volatility

The system was developed using python version 3.10 and tested on Kubuntu 22.10
