Saeed Amen has written several open source libraries in Python designed for finance. Over a year ago, Saeed released the pythalesians library. In summer 2016, Saeed split up the library into several more specialised modules, with a rewritten and easier to use API. finmarketpy has over 1000 stars on GitHub and has been forked over 100 times. It is now the second most popular Python trading library on GitHub, measured by number of stars. Cuemacro’s analytics and trading strategies are built on top of these open source libraries.
