 # Volatility Decay Visualizations with Streamlit (and Dash)
 
+[![Streamlit App Build](https://github.com/MarcoHuebner/volatility_decay_app/actions/workflows/run-tests.yaml/badge.svg)](https://github.com/MarcoHuebner/volatility_decay_app/actions/workflows/run-tests.yaml)

 This project contains visualizations of the volatility decay phenomenon as well as calculations regarding the Kelly criterion to deal with volatility decay. It is based on the [volatility decay equation](https://www.reddit.com/r/HFEA/comments/tue7n6/the_volatility_decay_equation_with_verification/) as well as a [paper](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1664823) and corresponding [blogpost](https://www.afrugaldoctor.com/home/leveraged-etfs-and-volatility-decay-part-2) dealing with leveraged (ETF) investing and in the light of the [Kelly criterion](https://rhsfinancial.com/2017/06/20/line-aggressive-crazy-leverage/). The project is built with and hosted on [Streamlit](https://volatilitydecayapp.streamlit.app/) and was initially built with Dash.
