## Deployment Recommendation
|
|
|
|
**Status**: ❌ REJECT - Not Production Ready
|
|
|
|
Model only passes 0/5 production criteria. Performance is insufficient for production deployment.
|
|
|
|
**Critical Issues**:
|
|
- ❌ Negative total return (-3.20%)
|
|
- ❌ Low Sharpe ratio (0.60 < 1.5)
|
|
- ❌ Excessive drawdown (35.40% > 20%)
|
|
- ❌ Poor win rate (38.0% < 50%)
|
|
- ❌ Negative alpha (-2.10%)
|
|
|
|
**Action**: Do not deploy. Retrain model with improved hyperparameters or different architecture.
|
|
|
|
