I wanted to quickly understand the market scenerio, so for I have developed this option chain analysis page. This page fetch data from official NSE website and analyse the option chain then displays the result. This project was developed for education purpose only, it has no commercial use.
You can also select expiry date, the data will be filtered and shown for that expiry only.
NSE India upgraded their API security. I have fixed the code in private repository. If your project is dependent on this library, I can give the code at cost.
The data is being fetched in realtime when a user visits the webpage via server. The data is accurate and unmodified version of NSE option chain. I have used CURL for scrapping option chain data which I found was working, NodeJs Request and Native HTTPs library was not working.
I have mentioned below the conditions, I have implemented in analysis of call options on the webpage.
Here, I am checking the price change and OI change and figuring out what is happening in the market.

| Positive | Positive | Long Buildup | BULLISH |
| Negative | Positive | Short Buildup | BEARISH |
