7d2bb9f392 fix: FR/Liq scoring bugs + compact UI 
Backend:
- FR threshold: 0.001→0.0003 (extreme), 0.0003→0.00005 (moderate)
- Liquidation SQL: side='SELL'/'BUY' → 'LONG'/'SHORT' (was never matching!)

Frontend:
- FR/Liq scores now inline in score column (compact)
- Removed bulky green badge buttons from position cards

58c72b4d90 fix: V5.2 TP/SL parameters - wider stops for better risk/reward 
V5.2: SL=3.0×ATR, TP1=2.0×ATR, TP2=4.5×ATR
V5.1: SL=2.0×ATR, TP1=1.5×ATR, TP2=3.0×ATR (unchanged)

Expected improvement: win/loss ratio 0.72→0.84, breakeven winrate 58%→54%

a9c3523a24 feat: independent strategy paper trading controls 
- 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']}

778cf8cce1 feat: V5.2 frontend differentiation - strategy tabs, side-by-side scores, visual badges 
- 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

2f9dce483c fix: simulate limit orders for TP/SL (match real trading) 
- TP/SL now exit at order price (limit order), not market price
- SL exits at sl_price, TP1 at tp1_price, TP2 at tp2_price
- Only timeout and signal_flip use market price (current price)
- Updated fix_historical_pnl.py to also correct exit_price
- This eliminates fake slippage in paper trading stats

45bad25156 fix(P0): pnl_r calculation + cooldown bypass + partition month bug 
P0-1: Reverse signal now bypasses cooldown - evaluate_signal always
      outputs direction, main loop checks direction+score>=60 for
      closing positions against trend (not blocked by COOLDOWN_MS)

P0-2: pnl_r unified to (exit-entry)/risk_distance across all exit
      scenarios (tp, sl, sl_be, timeout) in both paper_monitor.py
      and signal_engine.py. Old hardcoded values (1.5R/2.25R) were
      ~2x too high vs actual risk_distance basis.

P1-1: ensure_partitions month calculation fixed from timedelta(30d)
      to proper month arithmetic. Also fixed UTC timezone for
      partition boundaries.

9528d69a42 fix: deduplicate recent_large_trades to prevent memory bloat 
Each evaluate cycle was re-appending all qualifying trades from
win_fast, causing duplicates. Added seen-set dedup.

- collector: psycopg2 + execute_values批量写入
- signal-engine: psycopg2同步读写
- backfill: psycopg2 + ON CONFLICT DO NOTHING
