I built a portfolio optimization and backtest tool supporting 36,000 securities

I've built a free portfolio optimization and backtesting tool that I wanted to share with the community. I created it to scratch my own itch: powerful investment tools without the paywall.

Website: https://investest.io/ Demo: https://youtu.be/eTD-f8AHs1o

Key Features: * Portfolio optimization (Maximum Sharpe Ratio, Minimum Volatility) * Support for 36,000+ securities (stocks, ETFs, mutual funds) * Multiple portfolio creation, management and sharing * Daily-updated market data

Future Development Plans: * Scaling the infrastructure * Adding AI-powered chatbot and advisor * Implementing advanced portfolio insights

This is a side project, so updates might not be frequent. I'd love to get feedback from the community. What features would you find most useful? Any suggestions for improvement?
