- 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']}
- Sidebar: 信号/模拟盘 section headers
- Three paper trade entries: 全部持仓, V5.1模拟盘, V5.2模拟盘 (NEW badge)
- Paper page reads strategy from URL query params
- Suspense boundary for useSearchParams
- 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
Before: unrealR = full position × price move (wrong after TP1)
After: unrealR = 0.5×TP1_locked + 0.5×current_float (correct)
This fixes the display showing >1R floating profit that never
materializes in final PnL because only half position remains.
- 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
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.
