+
+## Comandos para Probar la Migración
+
+### 1. Instalación de Dependencias
+```bash
+cd /home/isem/workspace/projects/trading-platform/apps/ml-engine
+pip install -r requirements.txt
+```
+
+### 2. Verificar GPU (XGBoost CUDA)
+```bash
+python -c "import torch; print(f'CUDA Available: {torch.cuda.is_available()}')"
+python -c "import xgboost as xgb; print(f'XGBoost Version: {xgb.__version__}')"
+```
+
+### 3. Ejecutar Tests
+```bash
+# Tests de AMD Detector
+pytest tests/test_amd_detector.py -v
+
+# Tests de API
+pytest tests/test_api.py -v
+
+# Todos los tests
+pytest tests/ -v
+```
+
+### 4. Iniciar API
+```bash
+# Modo desarrollo
+uvicorn src.api.main:app --reload --port 8001
+
+# Modo producción
+uvicorn src.api.main:app --host 0.0.0.0 --port 8001 --workers 4
+```
+
+### 5. Probar Endpoints
+
+**Health Check:**
+```bash
+curl http://localhost:8001/health
+```
+
+**AMD Detection:**
+```bash
+curl -X POST "http://localhost:8001/api/amd/XAUUSD?timeframe=15m" \
+  -H "Content-Type: application/json"
+```
+
+**Backtest:**
+```bash
+curl -X POST "http://localhost:8001/api/backtest" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "symbol": "XAUUSD",
+    "start_date": "2024-01-01T00:00:00",
+    "end_date": "2024-02-01T00:00:00",
+    "initial_capital": 10000.0,
+    "risk_per_trade": 0.02
+  }'
+```
+
+**WebSocket (usando websocat o similar):**
+```bash
+websocat ws://localhost:8001/ws/signals
+```
+

+

+
+## Problemas Potenciales y Soluciones
+
+### Issue 1: Archivos Backtesting No Migrados Completamente
+**Problema:** Los archivos `engine.py`, `metrics.py`, `rr_backtester.py` requieren copia manual.
+
+**Solución:**
+```bash
+cd [LEGACY: apps/ml-engine - migrado desde TradingAgent]/src/backtesting/
+cp engine.py metrics.py rr_backtester.py \
+   /home/isem/workspace/projects/trading-platform/apps/ml-engine/src/backtesting/
+```
+
+### Issue 2: Phase2Pipeline Requiere Imports Adicionales
+**Problema:** Pipeline depende de módulos que pueden no estar migrados.
+
+**Solución:**
+- Verificar imports en `phase2_pipeline.py`
+- Migrar componentes faltantes de `data/` si es necesario
+- Adaptar rutas de imports si hay cambios en estructura
+
+### Issue 3: GPU No Disponible
+**Problema:** RTX 5060 Ti no detectada.
+
+**Solución:**
+```bash
+# Verificar drivers NVIDIA
+nvidia-smi
+
+# Reinstalar PyTorch con CUDA
+pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121
+```
+
+### Issue 4: Dependencias Faltantes
+**Problema:** Algunas librerías no instaladas.
+
+**Solución:**
+```bash
+# Instalar dependencias opcionales
+pip install ta  # Technical Analysis library
+pip install tables  # Para HDF5 support
+```
+
+---
+
+## Dependencias Críticas Faltantes
+
+Las siguientes pueden requerir migración adicional si no están en el proyecto:
+
+1. **`data/validators.py`** - Para DataLeakageValidator, WalkForwardValidator
+2. **`data/targets.py`** - Para Phase2TargetBuilder, RRConfig, HorizonConfig
+3. **`data/features.py`** - Para feature engineering
+4. **`data/indicators.py`** - Para indicadores técnicos
+5. **`utils/audit.py`** - Para Phase1Auditor
+
+**Acción Recomendada:**
+```bash
+# Verificar si existen
+ls -la apps/ml-engine/src/data/
+
+# Si faltan, migrar desde TradingAgent
+cp [LEGACY: apps/ml-engine - migrado desde TradingAgent]/src/data/*.py \
+   /home/isem/workspace/projects/trading-platform/apps/ml-engine/src/data/
+```
+
+---
+
+## Configuración GPU
+
+El sistema está configurado para usar automáticamente la RTX 5060 Ti (16GB VRAM):
+
+**XGBoost:**
+```python
+params = {
+    'tree_method': 'hist',
+    'device': 'cuda',  # Usa GPU automáticamente
+}
+```
+
+**PyTorch:**
+```python
+device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
+model = model.to(device)
+```
+
+**Verificación:**
+```python
+import torch
+print(f"GPU: {torch.cuda.get_device_name(0)}")
+print(f"Memory: {torch.cuda.get_device_properties(0).total_memory / 1e9:.2f} GB")
+```
+
+---
+
+## Próximos Pasos Recomendados
+
+### Corto Plazo (1-2 días)
+1. ✅ Migrar componentes faltantes de `data/` si es necesario
+2. ✅ Cargar modelos pre-entrenados en startup de API
+3. ✅ Implementar carga de datos OHLCV real
+4. ✅ Conectar AMD detector con datos reales
+
+### Mediano Plazo (1 semana)
+1. Entrenar modelos con datos históricos completos
+2. Implementar walk-forward validation en producción
+3. Configurar logging y monitoring
+4. Integrar con base de datos (MongoDB/PostgreSQL)
+
+### Largo Plazo (1 mes)
+1. Fine-tuning de LLM con señales históricas
+2. Dashboard de monitoreo real-time
+3. Sistema de alertas y notificaciones
+4. Optimización de hiperparámetros
+
