Hi! I'm Łukasz Wojtów, a software developer and stock market trader from Poland. To help with my day-to-day trading, I created Alis Studio - a software to manage portfolios, research stock market ideas, and do algo-trading analytics. It's an MVP but perfectly usable. It has a number of features that I couldn't find anywhere else:

- Parameter optimization with a genetic algorithm - Fuzzy optimization: randomly remove trades or whole markets and see what happens - Data mining: find rules how to exit trades sooner for better profit - Compare strategy results to random trading - Check current drawdown for statistical significance

and standard stuff like backtesting, trading signals and so on...

Of course, it's open-source. A GitHub star is much appreciated. Thanks!
