Vanna AI Streamlit App

Web server for chatting with your database

The Python Library For QtsApp which displays the option chain in near real-time. This program retrieves this data from the QtsApp site and then generates useful analysis of the Option Chain for the specified Index or Stock. It also continuously refreshes the Option Chain along with Implied Volatatlity (IV), Open Interest (OI), Delta, Theta, Vega, Gamma, Vanna, Charm, Speed, Zomma, Color, Volga, Veta at an interval of a second and visually displays the trend in various indicators useful for Technical Analysis.

A python application using Dash library and Mathematical functions to create GEX/VEX levels from the options chain. Supplied by Tradier.

Options are an integral part of hedging strategies, portfolio management and many other facets of the finance industry. And Greeks of an option are used to assess different dimensions of risk involved in taking an options position. Each risk variable is a result of an imperfect assumption or relationship of the option with an underlying variable. Hence, calculation of Greeks is of utmost importance. In our report, we have implemented techniques called Kernel smoothing and Kernel differentiation, using Monte Carlo simulations, to calculate the following Greeks: Delta, Vega, Gamma, Vomma and Vanna, of a European Digital option.
