After months of work, we've created something we think the HN community might find interesting: a spreadsheet interface that connects to 600+ exchanges with 1000+ built-in analysis tools. The core idea: if you already know spreadsheets, you shouldn't need to learn Python/R or set up complex infrastructure to do serious quantitative analysis. What's inside:

Portfolio optimization (including Dalio's risk parity approach) Monte Carlo simulations for backtesting Sharpe ratio, Black-Scholes, and risk analysis Real-time data from 10,000+ sources via connectors Direct execution to platforms like Robinhood AI assistants that can explain concepts and analyze your positions

The AI layer is particularly useful for learning - it can walk you through why certain strategies work, explain the math behind models, or help debug your analysis. We're offering a free tier to start, and we'd genuinely love feedback from folks here who've built their own trading systems or struggled with existing tools.
