Position Manager — Manajemen Posisi Cerdas
File:
src/position_manager.pyClass:SmartPositionManager,SmartMarketCloseHandlerFitur: Trailing Stop, Profit Protection, Market Close Handler
Apa Itu Position Manager?
Position Manager mengelola posisi terbuka secara aktif dan cerdas — trailing stop loss, proteksi profit, dan keputusan otomatis saat market mendekati penutupan.
Analogi: Position Manager seperti co-pilot yang mengawasi perjalanan — mengamankan keuntungan saat angin baik, dan mengambil tindakan darurat saat cuaca memburuk.
2 Komponen Utama
A. SmartPositionManager
Mengelola posisi aktif: trailing stop, breakeven, profit protection.
B. SmartMarketCloseHandler
Keputusan cerdas saat market mendekati penutupan (harian/weekend) — market close handler.
SmartPositionManager — 7 Kondisi Aksi
Untuk setiap posisi terbuka, dicek berurutan berdasarkan prioritas:

0. Market Close Check (Prioritas Tertinggi)
Dekat market close?
├── Profit >= $10 + dekat close → CLOSE (amankan profit)
├── Loss + dekat weekend + SL >50% hit → CLOSE (gap risk)
├── Loss + dekat weekend + loss > $100 → CLOSE (gap risk)
└── Loss kecil + dekat weekend → HOLD (bisa recovery Senin)
1. Regime Danger
Regime CRISIS atau HIGH_VOLATILITY + profit > $50:
→ CLOSE (amankan profit dari volatilitas)
2. Opposite Signal
Posisi BUY + sinyal bearish kuat + profit > $25:
→ CLOSE (amankan sebelum reversal)
Posisi SELL + sinyal bullish kuat + profit > $25:
→ CLOSE (amankan sebelum reversal)
3. Drawdown from Peak
Peak profit > $50 DAN drawdown > 30% dari peak:
→ CLOSE (profit sudah turun terlalu banyak)
Contoh: Peak $80, sekarang $50 → drawdown 37.5% → CLOSE
4. High Urgency
Urgency score >= 7 (dari 10) DAN profit > 0:
→ CLOSE (banyak sinyal bahaya bersamaan)
5. Breakeven Protection
Profit >= BE pips (ATR * 2.0, fallback 15 pips):
→ Pindah SL ke breakeven + 0.5*ATR buffer
(tidak bisa rugi lagi)
6. Trailing Stop
Profit >= trail start pips (ATR * 4.0, fallback 25 pips):
→ SL mengikuti harga dengan jarak ATR * 3.0 (fallback 10 pips)
(kunci profit sambil biarkan profit berjalan)
Impulse candle (range > 1.5x ATR):
→ Trail diperketat ke 1.5x ATR
7. Default: HOLD
Tidak ada kondisi terpenuhi → HOLD posisi
SmartMarketCloseHandler

Market Analysis (Urgency Score)
Urgency score menghitung tingkat bahaya pasar pada skala 0-10. Skor tinggi memicu exit otomatis.
Score dimulai dari 0, lalu ditambah:
Regime crisis/high_vol: +3
ML opposite >75% confidence: +2
RSI >75 (overbought): +2
RSI <25 (oversold): +2
Trend + momentum berlawanan: +3
Total max: ~10
Score >= 7 = HIGH URGENCY → tutup jika ada profit
| Komponen | Skor | Kondisi |
|---|---|---|
| Regime berbahaya | +3 | Crisis atau high volatility |
| ML sinyal berlawanan | +2 | Confidence > 75% + arah berlawanan posisi |
| RSI overbought | +2 | RSI > 75 (bahaya untuk posisi BUY) |
| RSI oversold | +2 | RSI < 25 (bahaya untuk posisi SELL) |
| Trend + momentum berlawanan | +3 | Trend dan momentum searah melawan posisi |
| Threshold | >= 7 | Tutup posisi jika ada profit |
