# NSE Options Open Interest Analysis using Python
The aim of this project is to able to fetch the Option chain data available from NSE API and use it to plot open interest data for analysis.

**Why do this when there are so many alternatives ?**

1. Showcase my python skills learnt during sabbatical
2. Opstra free account OI data is 15 mins delayed
3. Didnot want to pay :) for this service
4. Work with slowest internet connection
5. Provides ability to use and make data as per my usage
