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

## 🎯 NÄCHSTE SCHRITTE
|
||||
|
||||
### SOFORT (heute):
|
||||
1. ✅ **Entscheidung:** Historical Trades löschen oder behalten?
|
||||
```bash
|
||||
python cleanup_historical_trades.py
|
||||
```
|
||||
|
||||
2. ✅ **Backup-Automation:** Tägliche Backups einrichten

||||
python setup_automated_backup.py
|
||||
```
|
||||
|
||||
### DIESE WOCHE:
