Strategy League — fixed backtest that feeds the ranking
🤖 FreqAI strategies can't be sandbox-tested for now — they need model libraries, trained model files and (for FreqAI) hours of training compute per run — so this strategy isn't League-ranked. Its code analysis, tags and bias checks above still apply.
Backtests — over a market period
Backtest this strategy over a chosen crypto-cycle period. These don't affect the League ranking, and need that period's candle data downloaded.
🤖 Not available for FreqAI/ML strategies for now — the sandbox has no model libraries or trained model files (see the Strategy League tab).
