| I've built a cryptocurrency screener that handles 400+ spot cryptocurrencies with plans to scale to 10K+ by integrating top exchanges. Key technical features - Server-side filtering/sorting to handle massive datasets without browser limitations - Flexible multi-condition screening with AND/OR operators - Technical indicator calculations (RSI, moving averages, performance metrics) - Search history persistence Architecture The architecture uses F# for the filtering backend and TypeScript/Angular frontend. All filtering logic runs server-side, so users can screen across the entire crypto universe instantly. The screener is part of a larger no-code backtesting platform I've been building as a solo developer (former portfolio manager). Feedback Looking for feedback on the filtering UX and any additional screening criteria that would be valuable. Try it: https://cryptoquant.dev/instruments/screener |
