- Removed 0.7*ATR multiplier from signal_engine and paper_monitor
- risk_distance now stored per-trade in paper_trades table
- paper_monitor/signal_engine read risk_distance from DB (no hardcoded values)
- V5.1 TP/SL: 2.0/1.5/3.0 -> 1.4/1.05/2.1 (same actual distance)
- V5.2 TP/SL: 3.0/2.0/4.5 -> 2.1/1.4/3.15 (same actual distance)
- Fixed V5.2 pnl_r: all historical values corrected by *2/3
- API unrealized_pnl_r also reads from DB risk_distance
- V5.1 paper: signal-history?strategy=v51_baseline
- V5.2 paper: signal-history?strategy=v52_8signals
- API now returns factors in signal-history
- Each signal shows layer score badges below
- signal_indicators table: added strategy column
- Each strategy gets its own row per cycle
- API /api/signals/latest?strategy=v51_baseline|v52_8signals
- API /api/signals/signal-history?strategy=...
- V5.1 page reads v51_baseline data, V5.2 reads v52_8signals
- Now V5.1 and V5.2 show truly independent scores
- Each strategy has its own position count (max 4 each)
- paper_config.enabled_strategies: per-strategy toggle
- is_strategy_enabled() checks both master switch and strategy list
- API: /api/paper/config now supports enabled_strategies array
- Config auto-loads on API startup
Usage: POST /api/paper/config {enabled_strategies: ['v52_8signals']}
- Paper page: prominent strategy tabs (全部/V5.1/V5.2) at top
- Paper trades: strategy column with color-coded badges (blue=V5.1, green=V5.2)
- Paper positions: FR/Liq scores displayed prominently for V5.2
- Signals page: side-by-side V5.1 vs V5.2 score comparison cards
- Signals page title updated to 'V5.1 vs V5.2'
- New API endpoint for strategy comparison data
- Layout: local font fallback for build stability
