QtsApp
QtsApp is a Python library designed to retrieve and analyze option chain data for specified stocks and indices from the QtsApp website in near real-time. It continuously refreshes data at one-second intervals, displaying key metrics including Implied Volatility, Open Interest, and various Greeks such as Delta, Theta, Gamma, and Vega. The library also provides higher-order Greeks like Vanna, Charm, Speed, Zomma, Color, Volga, and Veta, helping users visualize trends and conduct technical analysis. To use the software, users must install the library, clone the repository, and configure authentication credentials via environment files using either a username-password method or manual API key and token setup for Google sign-in. The tool requires a free QtsApp account to access live data for NFO instruments and valid expiries. Users should run the example script during market hours to receive live updates. Please note that access to higher-order Greeks is currently restricted by the source website, and the library
