Add database cleanup and backup automation

Created comprehensive database maintenance tools:

1. database_cleanup.py (✅ EXECUTED)
   - Fixed 102 unknown sessions → assigned to correct sessions
   - Revealed true win rate: 67.8% (not 18.5%!)
   - Created automatic backup before changes

2. cleanup_historical_trades.py
   - Handles 240 'historical' trades with NULL profit
   - 3 options: Delete / Mark / Set to breakeven
   - Interactive selection with backup

3. setup_automated_backup.py
   - Daily automated backups
   - Windows Task Scheduler integration
   - 7-day backup rotation
   - Manual backup option

Results after cleanup:
- ✅ Unknown sessions: 0 (was 102)
- ✅ Session distribution: asian 132, ny 64, overlap 75, london 58
- ✅ Win rate: 67.8% (61 wins / 90 trades)
- ✅ Backup created: trading_bot_before_cleanup_20251226_162438.db
- ⏳ 240 historical trades pending decision (recommend delete)

Next steps:
1. Run cleanup_historical_trades.py (option 1: delete)
2. Setup automated backups via Task Scheduler
3. Re-analyze performance with correct session data

+# 🔧 Database Cleanup - Zusammenfassung
+
+**Datum:** 26. Dezember 2025
+**Status:** ✅ ABGESCHLOSSEN (Phase 1)
+
+---
+
+## ✅ WAS WURDE BEHOBEN
+
+### 1. Unknown Sessions → FIXED ✅
+**Problem:**
+- 102 Trades hatten `session='unknown'`
+- Session-Detection hat versagt
+
+**Lösung:**
+- Session basierend auf `entry_time` UTC-Hour berechnet
+- Alle 102 Trades korrigiert
+
+**Neue Session-Verteilung:**
+```
+asian:   132 Trades (war: 90)  ← +42 from unknown
+overlap:  75 Trades (war: 51)  ← +24 from unknown
+ny:       64 Trades (war: 51)  ← +13 from unknown
+london:   58 Trades (war: 35)  ← +23 from unknown
+manual:    1 Trade
+unknown:   0 Trades ✅ (war: 102)
+```
+
+**Impact:**
+- ✅ Alle Sessions jetzt korrekt zugeordnet
+- ✅ Genauere Session-Performance Statistiken
+- ✅ Session Filter arbeitet präziser
+
+---
+
+### 2. Performance-Statistiken → BEREINIGT ✅
+**Neue korrekte Zahlen (nur valide Trades):**
+```
+Total Trades: 90 (closed)
+Wins: 61 (67.8%)  ← NICHT 18.5%!
+Losses: 29 (32.2%)
+Avg Win: $153.58
+Avg Loss: $-36.65
+Total Profit: $8,305.78
+```
+
+**Wichtig:**
+- **67.8% Win-Rate** ist die ECHTE Zahl!
+- Vorher: 18.5% weil 240 historical Trades mitgezählt wurden
+- Jetzt: Nur closed Trades = valide Performance-Daten
+
+---
+
+### 3. Backup System → AKTIV ✅
+**Was wurde erstellt:**
+- Automatisches Backup vor Cleanup
+- Backup-Verzeichnis: `backups/`
+- Aktuelles Backup: `trading_bot_before_cleanup_20251226_162438.db`
+
+**Verfügbare Scripts:**
+- `setup_automated_backup.py` - Tägliche Backups
+- `database_cleanup.py` - Session-Fixes
+- `cleanup_historical_trades.py` - Historical-Trades behandeln
+
+---
+
+## ⏳ NOCH ZU ENTSCHEIDEN
+
+### 240 "Historical" Trades mit NULL Profit
+**Problem:**
+- 240 Trades haben `status='historical'` und `net_profit=NULL`
+- Entry Price = 0
+- Keine Exit Price
+- Vermutlich alte Migrations-Daten (November 3-26)
+
+**Optionen:**
+
+#### Option 1: LÖSCHEN (Empfohlen) ✅
+```bash
+python cleanup_historical_trades.py
+# Wahl: 1
+```
+- **Pro:** Saubere Datenbank, nur valide Trades
+- **Con:** Daten unwiederbringlich weg
+- **Empfehlung:** JA - sind kaputte Daten
+
+#### Option 2: Als "invalid" MARKIEREN
+```bash
+python cleanup_historical_trades.py
+# Wahl: 2
+```
+- **Pro:** Daten bleiben erhalten (für Analyse)
+- **Con:** Nimmt Speicherplatz
+- **Empfehlung:** Nur wenn Sie die Daten später untersuchen wollen
+
+#### Option 3: net_profit = 0 setzen (NICHT empfohlen)
+```bash
+python cleanup_historical_trades.py
+# Wahl: 3
+```
+- **Pro:** Fließen in Statistik ein
+- **Con:** Verfälscht Performance (240 Breakeven-Trades?)
+- **Empfehlung:** NEIN - würde Win-Rate von 67.8% auf ~21% senken
+

+
+## 📊 VORHER/NACHHER VERGLEICH
+
+### Session-Zuordnung:
+| Session | Vorher | Nachher | Änderung |
+|---------|--------|---------|----------|
+| asian | 90 | 132 | +42 ✅ |
+| ny | 51 | 64 | +13 ✅ |
+| overlap | 51 | 75 | +24 ✅ |
+| london | 35 | 58 | +23 ✅ |
+| unknown | 102 | 0 | -102 ✅ |
+
+### Performance-Statistiken:
+| Metrik | Vorher (falsch) | Nachher (korrekt) |
+|--------|-----------------|-------------------|
+| Win-Rate | 18.5% ❌ | 67.8% ✅ |
+| Total Trades | 330 (inkl. historical) | 90 (nur closed) |
+| Wins | 61 | 61 |
+| Losses | 29 | 29 |
+| Missing Data | 240 ❌ | 240 (zu klären) |
+
+---
+
+## 🎯 NÄCHSTE SCHRITTE
+
+### SOFORT (heute):
+1. ✅ **Entscheidung:** Historical Trades löschen oder behalten?
+   ```bash
+   python cleanup_historical_trades.py
+   ```
+
+2. ✅ **Backup-Automation:** Tägliche Backups einrichten
+   ```bash
+   python setup_automated_backup.py
+   ```
+
+### DIESE WOCHE:

+
+**Empfehlung:** Wahl 1 (Task Scheduler)
+
+---
+
+## 📊 NEUE SESSION-PERFORMANCE (nach Fix)
+
+### Asian Session (132 Trades - beste!)
+- Vorher: 90 Trades, $6,943
+- **Jetzt:** 132 Trades (+42 from unknown)
