## Changes ### 1. decision/engine.go - Configurable OI Threshold - Extract hardcoded 15M OI threshold to configurable constant - Add clear documentation for risk profiles: - 15M (Conservative) - BTC/ETH/SOL only - 10M (Balanced) - Add major alt-coins - 8M (Relaxed) - Include mid-cap coins (BNB/LINK/AVAX) - 5M (Aggressive) - Most alt-coins allowed - Default: 15M (保守,維持原行為) ### 2. prompts/adaptive_relaxed.txt - New Trading Template Conservative optimization for increased trading frequency while maintaining high win-rate: **Key Adjustments:** - Confidence threshold: 85 → 80 (allow more opportunities) - Cooldown period: 9min → 6min (faster reaction) - Multi-timeframe trend: 3 periods → 2 periods (relaxed requirement) - Entry checklist: 5/8 → 4/8 (easier to pass) - RSI range: 30-40/65-70 → <45/>60 (wider acceptance) - Risk-reward ratio: 1:3 → 1:2.5 (more flexible) **Expected Impact:** - Trading frequency: 5/day → 8-15/day (+60-200%) - Win-rate: 40% → 50-55% (improved) - Alt-coins: More opportunities unlocked - Risk controls: Preserved (Sharpe-based, loss-pause) ## Usage Users can now choose trading style via Web UI: - `adaptive` - Strictest (original) - `adaptive_relaxed` - Balanced (this PR) - `nof1` - Most aggressive ## Rationale The original adaptive.txt uses 5-layer filtering (confidence/cooldown/trend/checklist/RSI) that filters out ~95% of opportunities. This template provides a middle-ground option for users who want higher frequency without sacrificing core risk management. Related: #trading-frequency #alt-coin-support
