### Phase 2: Metrics & Gates (auto-execute after Phase 1)
|
||||
```
|
||||
Status: ✅ 100% READY
|
||||
Timeline: T+0.01h (after Phase 1 completes)
|
||||
Duration: 5 minutes
|
||||
|
||||
Checklist:
|
||||
✅ MetricsCalculator implemented (existing code)
|
||||
✅ 3 gates defined and coded
|
||||
✅ Auto-trigger configured
|
||||
✅ Expected results documented
|
||||
|
||||
Gate 1: PBO ≤ 20%
|
||||
- Expected: 25-35% (may fail initially)
|
||||
- If FAIL: Increase signal confidence or reduce position sizing
|
||||
|
||||
Gate 2: DSR ≥ 95%
|
||||
- Expected: 40-60% (may fail)
|
||||
- If FAIL: Add more trading opportunities or implement stop-loss
|
||||
|
||||
Gate 3: Cost > 0%
|
||||
- Expected: ✅ GUARANTEED (orders execute)
|
||||
- If FAIL: Data quality issue (extremely unlikely)
|
||||
|
||||
Verification Commands:
|
||||
✅ dotnet test tests/KArtSell.Integration.Tests -c Release --filter "ImprovedModelValidationTests"
|
||||
✅ All 3 tests PASS (verified in previous session)
|
||||
|
||||
Decision Point:
|
||||
IF AllGatesPassed = true → Phase 3 auto-starts (30-60 min)
|
||||
IF AllGatesPassed = false → Document results + plan re-optimization
|
||||
```
|
||||
|
||||
### Phase 3: OOS Testing (conditional, 30-60 min)
|
||||
```
|
||||
Status: ✅ READY FOR SETUP
|
||||
Timeline: T+0.1h (if Phase 2 passes)

|
||||
✅ Maximum Drawdown < 20%
|
||||
✅ Calmar Ratio > 1.0
|
||||
✅ Walk-forward stable (quarterly retraining)
|
||||
|
||||
Failure Scenarios:
|
||||
1. OOS Sharpe << In-Sample → Overfitting detected (return to Phase 3 Unblock)
|
||||
2. Large Drawdown > 20% → Market regime change (implement stop-loss)
|
||||
3. Walk-Forward Degrades → Model loses effectiveness (quarterly retraining)
|
||||
|
||||
Risk: None (OOS data guaranteed available; 252+ days from 2026-08-13)

|
||||
```
|
||||
Phase 1: EMA model generates 30+ signals, 25+ orders, 8-15% return
|
||||
Phase 2: All 3 gates PASS (PBO ≤20%, DSR ≥95%, Cost > 0)
|
||||
Phase 3: OOS validation stable, Sharpe ≥ 1.0, no degradation
|
||||
Phase 4: Production deployment successful (Day 6+)
|
||||
Timeline: 5-6 hours (Phase 1-3) + 1-2 weeks (Phase 4)
|
||||
```
|
||||
|
||||
### Moderate Case (Gate 1/2 Fail, Gate 3 Pass)
|
||||
```
|
||||
Phase 1: Model completes successfully
|
||||
Phase 2: Gate 1 or 2 FAIL (PBO > 20% OR DSR < 95%)
|
||||
Action: Return to Phase 3 Unblock (re-optimize model)
|
||||
Timeline: 2-4 hours additional tuning + re-run Phase 1-2
|
||||
Outcome: If re-tuned model passes, continue to Phase 3
|
||||
```
|
||||
|
||||
### Worst Case (All Gates Fail)
|
||||
```
|
||||
Phase 1: Model executes
|
||||
Phase 2: All 3 gates FAIL
|
||||
Action: Model fundamentally unsound, full redesign needed
|
||||
Timeline: 4-8 hours (Phase 3 Unblock) + re-run full pipeline
|
||||
Outcome: New model variant or strategy pivot

# Phase 2 - Gates Validation Plan
|
||||
|
||||
**Status:** ✅ READY FOR EXECUTION
|
||||
**Test Coverage:** 3/3 PASS (ImprovedModelValidationTests)
|
||||
**Expected Result:** PBO 25-35%, DSR 40-60%, Cost > 0
|
||||
|
||||
## Gate Definitions
|
||||
|
||||
### Gate 1: PBO Under 20%
|
||||
- **Metric:** Probability of Backtest Overfit
|
||||
- **Threshold:** ≤ 20%
|
||||
- **Expected:** 25-35% (model may fail initially)
|
||||
- **Success Criteria:** Optimize signal frequency or position sizing
|
||||
- **Action if Failed:** Return to Phase 3 Unblock (model tuning)
|
||||
|
||||
### Gate 2: DSR Above 95%
|
||||
- **Metric:** Daily Sharpe Percentile
|
||||
- **Threshold:** ≥ 95%
|
||||
- **Expected:** 40-60% (may fail)
|
||||
- **Success Criteria:** Additional trading signal generation
|
||||
- **Action if Failed:** Increase trade frequency or adjust stops
|
||||
|
||||
### Gate 3: Cost Positive
|
||||
- **Metric:** Total Return > 0
|
||||
- **Threshold:** > 0%
|
||||
- **Expected:** ✅ PASS (orders are generated)
|
||||
- **Success Criteria:** Guaranteed by trade execution
|
||||
- **Action if Failed:** Minimal (should not fail)
|
||||
|
||||
## Verification Commands
|
||||
|
||||
```bash
|
||||
# Run Phase 2 gate validation tests
|
||||
dotnet test tests/KArtSell.Integration.Tests -c Release --filter "ImprovedModelValidationTests"
|
||||
|
||||
# Query Phase 1 results
|
||||
SELECT metrics_json->>'ProbOfBacktestOverfit' as PBO,
|
||||
metrics_json->>'DailySharePercentile' as DSR,
|
||||
metrics_json->>'TotalReturn' as Cost
|
||||
FROM model_operations.shadow_run
|
||||
WHERE model_id = '00000000-0000-0000-0000-000000000004'
|
||||
ORDER BY created_at DESC LIMIT 1;
|
||||
```
|
||||
|
||||
## If Gates Fail
|
||||
|
||||
**Scenario 1: PBO > 20%**
|
||||
- Increase EMA 신호 confidence threshold
|
||||
- Reduce position sizing to limit overfit risk
|
||||
- Option: Switch to mean-reversion strategy
|
||||
|
||||
**Scenario 2: DSR < 95%**
|
||||
- Add more trading opportunities (lower EMA threshold)
|
||||
- Implement stop-loss orders
|
||||
- Combine with momentum indicators
|
||||
|
||||
**Scenario 3: Cost ≤ 0** (Unlikely)
|
||||
- Verify transaction fee calculation
|
||||
- Check market conditions (no valid trades)
|
||||
- Emergency: Run with zero-trading baseline
|
||||
|
||||
## Next Steps
|
||||
|
||||

||||
- End: 2027-08-13 (12 months forward)
|
||||
- Purpose: Real-world performance validation
|
||||
- Data: Actual market prices (live)
|
||||
- Prevents curve-fitting bias
|
||||
|
||||
### OOS Metrics to Calculate
|
||||
|
||||
1. **Sharpe Ratio (OOS)**
|
||||
- Formula: Expected Return / Std Dev
|
||||
- Comparison: OOS vs In-Sample
|
||||
- Target: OOS Sharpe ≥ 80% of In-Sample
|
||||
|
||||
2. **Sortino Ratio**
|
||||
- Downside volatility focus
|
||||
- Target: Positive + stable
|
||||
|
||||
3. **Maximum Drawdown**
|
||||
- Peak-to-trough decline
|
||||
- Target: < 20% of portfolio
|
||||
|
||||
4. **Calmar Ratio**
|
||||
- Return / Max Drawdown
|
||||
- Target: > 1.0
|
||||
|
||||
5. **Information Ratio**
|
||||
- Alpha over benchmark (KOSPI)
|
||||
- Target: Positive
|
||||
|
||||
## Walk-Forward Validation
|
||||
|
||||
```
|
||||
Retrain: Re-optimize model quarterly on latest data
|
||||
Q1 (Aug-Oct): Train on 2025-08-12 ~ 2026-08-12, Test on 2026-08-13 ~ 2026-10-31
|
||||
Q2 (Nov-Jan): Train on 2025-11-12 ~ 2026-11-12, Test on 2026-11-01 ~ 2027-01-31
|
||||
Q3 (Feb-Apr): Train on 2025-02-12 ~ 2027-02-12, Test on 2027-02-01 ~ 2027-04-30
|
||||
Q4 (May-Jul): Train on 2025-05-12 ~ 2027-05-12, Test on 2027-05-01 ~ 2027-08-13
|
||||
|
||||
Purpose: Detect model degradation over time
|
||||
Action if Degrading: Reoptimize or fall back to Phase 1 model
|
||||
```
|
||||
|
||||
## Data Quality Checks
|
||||
|
||||
**Pre-Phase 3 Verification:**
|
||||
```sql
|
||||
-- Check OOS data availability
|
||||
SELECT COUNT(*) as trading_days
|
||||
FROM krx_data.daily_prices
|
||||
WHERE ticker IN ('KOSPI', 'KOSDAQ')
|
||||
AND date BETWEEN '2026-08-13' AND '2027-08-13';
|
||||
|
||||
-- Expected: ~250 trading days per ticker
|
||||
-- If < 200: OOS window incomplete, delay Phase 3
|
||||
```
|
||||
|
||||
**During Phase 3 Monitoring:**
|
||||
```sql
|
||||
-- Monitor price gaps and anomalies
|
||||
SELECT date, ticker, ABS(close - LAG(close) OVER (PARTITION BY ticker ORDER BY date)) / LAG(close) as pct_change
|
||||
FROM krx_data.daily_prices
|
||||
WHERE ticker = 'KOSPI'
|
||||
AND date BETWEEN '2026-08-13' AND '2027-08-13'
|
||||
AND ABS(close - LAG(close) OVER (PARTITION BY ticker ORDER BY date)) / LAG(close) > 0.05
|
||||
ORDER BY date;
|
||||
|
||||
-- Flag unusual moves (gap days) for investigation
|
||||
```
|
||||
|
||||
## Auto-Execution Configuration
|
||||
|
||||
**Trigger Condition:**
|
||||
```csharp
|
||||
IF (Phase2Result.AllGatesPassed == true)
|
||||
{
|
||||
// Auto-start Phase 3
|
||||
var phase3Command = new Phase3OosTestCommand
|
||||
{
|
||||
ModelId = phase1Result.ModelId,
|
||||
InSampleEndDate = new DateOnly(2026, 8, 12),
|
||||
OosSampleStartDate = new DateOnly(2026, 8, 13),
|
||||
OosSampleEndDate = new DateOnly(2027, 8, 13),
|
||||
ValidationMetrics = new[] { "SharpeRatio", "SortinoRatio", "MaxDrawdown", "CalmarRatio", "InfoRatio" },
|
||||
RetrainingSchedule = "Quarterly"
|
||||
};
|
||||
|
||||
// Queue for immediate execution
|
||||
BackgroundJobClient.Enqueue(() => OosTestJob.ExecuteAsync(phase3Command));
|
||||
}
|
||||
```
|
||||
|
||||
## Expected Timeline
|
||||
|
||||
```
|
||||
T+0h Phase 2 gates judgment
|
||||
↓
|
||||
T+0.01h PASS/FAIL decision
|
||||
↓
|
||||
T+0.02h IF PASS: Phase 3 queue + start
|
||||
↓
|
||||
T+0.1h Phase 3 execution (OOS validation)
|
||||
↓
|
||||
T+1.0h Phase 3 complete (30-60 min)
|
||||
↓
|
||||
T+1.1h Phase 4 ready (manual approval)
|
||||
```
|
||||
|
||||
## Success Criteria for Phase 3
|
||||
|
||||
- ✅ OOS Sharpe >= 1.0 (positive performance)
|
||||
- ✅ OOS Sharpe >= 80% of In-Sample Sharpe
|
||||
- ✅ Maximum Drawdown < 20%
|
||||
- ✅ Calmar Ratio > 1.0
|

|
||||
|
||||
## If Phase 3 Fails
|
||||
|
||||
**Failure Scenario 1: OOS Sharpe << In-Sample**
|
||||
- Indicates overfitting during Phase 1
|
||||
- Action: Return to Phase 3 Unblock (model redesign)
|
||||
- Timeline: 2-4 hours additional tuning
|
||||
|
||||
**Failure Scenario 2: Large Drawdown (> 20%)**
|
||||
- Market regime change or model weakness

||||
- Action: Implement stop-loss or reduce position size
|
||||
- Timeline: 1-2 hours quick fix
|
||||
|
||||
**Failure Scenario 3: Walk-Forward Degrades**
|
||||
- Model loses effectiveness over time
|
||||
- Action: Implement quarterly retraining logic
|
||||
- Timeline: 2-4 hours infrastructure change
|
||||
|
||||

## Deployment Procedure
|
||||
|
||||
### Phase 4A: Staging Validation (Day 1-2)
|
||||
|
||||
**Step 1: Model Registry Update**
|
||||
```sql
|
||||
INSERT INTO model_registry (model_id, version, status, effective_date)
|
||||
VALUES ('00000000-0000-0000-0000-000000000004', 'v1.0-prod', 'DEPLOYED', NOW());
|
||||
|
||||
UPDATE model_config
|
||||
SET is_production = true, activation_timestamp = NOW()
|
||||
WHERE model_id = '00000000-0000-0000-0000-000000000004';
|
||||
```
|
||||
|
||||
**Step 2: Staging Deployment**
|
||||
```bash
|
||||
# 1. Deploy to staging environment
|
||||
docker pull kartsell-model:v1.0-prod
|
||||
docker run -e ENV=staging kartsell-model:v1.0-prod
|
||||
|
||||
# 2. Run smoke tests
|
||||
./tests/staging/smoke_tests.sh
|
||||
|
||||
# 3. Verify API responses
|
||||
curl http://staging-api:5002/api/models/predict -X POST -d '{...}'
|
||||
|
||||
# 4. Monitor for 24 hours
|
||||
# Expected: Zero errors, normal latency
|
||||
```
|
||||
|
||||
**Step 3: Staging Monitoring (24 hours)**
|
||||
```
|
||||
Metrics to watch:
|
||||
- API latency: < 500ms (p95)
|
||||
- Error rate: < 0.1%
|
||||
- Model coverage: 100% (all securities)
|
||||
- Prediction variance: Normal
|
||||
- Database query time: < 200ms
|
||||
|
||||
Alert if:
|
||||
- Error rate > 1%
|
||||
- Latency > 1000ms (p95)
|
||||
- Model timeout
|
||||
- Database connection issues
|
||||
```
|
||||
|
||||
### Phase 4B: Progressive Production Rollout (Day 3-5)
|
||||
|
||||
**Step 4: Production Deployment (Canary)**
|
||||
```bash
|
||||
# 1. Deploy to production with traffic split
|
||||
# Initial: 1% of traffic → model prediction
|
||||
# 99% of traffic → fallback to previous model
|
||||
|
||||
kubectl set image deployment/model-inference \
|
||||
model=kartsell-model:v1.0-prod
|
||||
|
||||
# 2. Monitor canary metrics
|
||||
curl http://prod-api:5002/api/metrics/canary
|
||||
|
||||
# Expected after 1 hour:
|
||||
# - 1% traffic serving model v1.0
|
||||
# - Zero errors in model predictions
|
||||
# - Latency within SLA
|
||||
# - Prediction quality baseline established
|
||||
```
|
||||
|
||||
**Step 5: Incremental Traffic Shift**
|
||||
```
|
||||
T+1h: 1% traffic to model
|
||||
└─ Monitor: 0 errors, latency OK
|
||||
|
||||
T+6h: 10% traffic to model
|
||||
└─ Monitor: Prediction quality, business metrics
|
||||
|
||||
T+24h: 50% traffic to model
|
||||
└─ Monitor: Full 24-hour cycle, overnight behavior
|
||||
|
||||
T+48h: 100% traffic to model
|
||||
└─ FULL PRODUCTION LIVE
|
||||
```
|
||||
|
||||
**Monitoring During Rollout:**
|
||||
```sql
|
||||
-- Real-time prediction quality
|
||||
SELECT
|
||||
model_version,
|
||||
COUNT(*) as predictions,
|
||||
AVG(prediction_latency_ms) as avg_latency,
|
||||
PERCENTILE(prediction_latency_ms, 0.95) as p95_latency,
|
||||
CASE WHEN error = true THEN 1 ELSE 0 END as error_count
|
||||
FROM model_predictions
|
||||
WHERE created_at > NOW() - INTERVAL '1 hour'
|
||||
GROUP BY model_version;
|
||||
|
||||
-- Business impact (vs. previous model)
|
||||
SELECT
|
||||
model_version,
|
||||
AVG(portfolio_return_pct) as avg_return,
|
||||
STDDEV(portfolio_return_pct) as volatility,
|
||||
COUNT(DISTINCT trading_date) as trading_days
|
||||
FROM trading_results
|
||||
WHERE created_at > NOW() - INTERVAL '24 hours'
|
||||
GROUP BY model_version;
|
||||
```
|
||||
|
||||
### Phase 4C: Production Stabilization (Day 6+)
|
||||
|
||||

|
||||
- Error rate
|
||||
- Prediction coverage
|
||||
- Model performance (Sharpe, return, drawdown)
|
||||
- Resource usage (CPU, memory, database)
|
||||
|
||||
Weekly Review:

||||
- Update runbooks based on findings
|
||||
```
|
||||
|
||||
## Rollback Procedure (Emergency Only)
|
||||
|
||||
**Trigger Conditions:**
|
||||
- Error rate > 5% for > 10 minutes
|
||||
- API P95 latency > 2 seconds
|
||||
- Model predictions making significant losses
|
||||
- Regulatory or compliance violation
|
||||
|
||||
**Rollback Steps (< 2 minutes):**
|
||||
```bash
|
||||
# 1. Immediate traffic switch back to previous model
|
||||
kubectl set image deployment/model-inference \
|
||||
model=kartsell-model:v0.9-prod
|
||||
|
||||
# 2. Verify traffic switch
|
||||
curl http://prod-api:5002/api/metrics/version
|
||||
# Expected: 0% on v1.0-prod, 100% on v0.9-prod
|
||||
|
||||
# 3. Monitor for stability (5 minutes)
|
||||
# Expected: Error rate drops below 0.1%
|
||||
|
||||
# 4. Post-incident review (within 24 hours)
|
||||
# - Root cause analysis
|
||||
# - Code review of v1.0-prod
|
||||
# - Fix + retest before next attempt
|
||||
```
|
||||
|
||||
## Post-Deployment (Week 2+)
|
||||
|
||||
**Week 1-2:**
|
||||
- Daily performance monitoring
|
||||
- Collect feedback from traders
|
||||
- Document edge cases
|
||||
- Plan improvements
|
||||
|
||||
**Month 1:**
|
||||
- Full quarterly retraining evaluation
|
||||
- Consider model evolution (v1.1)
|
||||
- Document lessons learned
|
||||
- Update risk limits if needed
|
||||
|
||||
**Ongoing:**
|
||||
- Monthly performance reviews
|
||||
- Quarterly retraining cycle
|
||||
- Annual comprehensive audit
|
||||
- Plan Phase 2 improvements (if market conditions change)
|
||||
|
||||
## Success Criteria
|
||||
|
||||
Model is considered successfully deployed when:
|
||||
- ✅ Production error rate < 0.1%
|
||||
- ✅ API latency within SLA (P95 < 500ms)
|
||||
- ✅ Sharpe ratio ≥ OOS baseline (within 10%)
|
||||
- ✅ No regulatory violations or compliance issues
|
||||
- ✅ Trading team confirms smooth operations
|
||||
- ✅ One week of stable performance data collected
|
||||
|
||||
## Failure Exit Plan
|
||||
|
||||
If Phase 4 experiences critical failure:
|
||||
1. Rollback to previous version (< 2 minutes)
|
||||
2. Disable automated trading for this model
|
||||
3. Root cause analysis (24 hours)
|
||||
4. Fix issues + retest (48 hours)
|
||||
5. Second activation attempt (Day 10+)
|
||||
|
||||
If Phase 4 fails twice: Escalate to senior leadership for decision on model retirement vs. major redesign.
