12 Commits • 2 Features
Mar 1, 2026During March 2026, freqtrade/freqtrade delivered targeted feature enhancements and reliability improvements that directly enhance trading decision support and metric accuracy. CrossMarketPairList was enhanced with tests, a refactor to use pairs_exist_on, documentation updates, refined filter logic (including whitelist behavior), and removal of the obsolete needstickers property. RemotePairList received enhancements enabling optional number_assets, improved startup messaging for accurate pair counts, and clearer string/description representations, along with updated docs. A robustness fix was applied to CAGR calculations to correctly handle zero or negative values in start balance, final balance, or days elapsed, ensuring stable financial metrics. Collectively, these changes improve reliability, observability, and maintainability, while delivering more accurate market data and performance signals.
