Agent M19: Backtesting CI/CD Quick Reference

Mission: Verify backtesting in CI/CD pipeline and data usage strategy Status: COMPLETE (546-line comprehensive report) Production Readiness: 75% (gaps identified with actionable fixes)

---

Key Findings at a Glance

Question 1: Are backtest tests part of CI pipeline?

YES - Partially Integrated

• 19+ backtesting service test files
• 100+ individual backtest tests
• Tests run on every PR, push, and scheduled nightly (2 AM UTC)
• Coverage: DBN loading, multi-symbol validation, strategy execution, ML integration

Where: .github/workflows/ci.yml + 6 additional workflows

Question 2: Do CI tests use real DBN data or mocks?

REAL DATA FOR INTEGRATION + MOCKS FOR SPEED

• Integration tests: Real Databento (.dbn) files
• Unit tests: Mock in-memory repositories
• Data sources: ES.FUT, NQ.FUT, 6E.FUT, ZN.FUT, CL.FUT, GC.FUT
• 90+ days training data available (Jan-Apr 2024 Q1)
• Daily quality validation (minimum score 70/100)

Performance: 0.70ms per file (14.3x faster than 10ms target)

Question 3: What's the CI test pass rate for backtesting?

98.3% OVERALL (1,403/1,427 tests passing)

• Backtesting Service: ~98%+ passing
• Service Integration: 22/22 tests passing
• DBN Integration: All validation tests passing
• E2E Ensemble: 0/22 (proto schema issues blocking)

Key Tests:

• Start Backtest: 6 tests
• Get Results: 3 tests
• Multi-symbol validation: 5 tests
• Strategy execution: 8 tests
• ML integration: 4 tests
• Service workflow: 1 comprehensive test

Question 4: Are there nightly regression backtest runs?

NO - MAJOR GAP IDENTIFIED

• Data validation runs nightly (2 AM UTC)
• Performance benchmarking runs on main branch
• MISSING: Full backtest regression comparing Wave C vs Wave D
• MISSING: Sharpe/Win Rate/Drawdown metric comparison
• MISSING: All 225 features end-to-end validation

CI Pipeline Architecture

PR/PUSH → Quick Checks → Test Suite → Integration → Benchmarks → Success
  (2-3m)      (10-15m)      (5-10m)      (varies)     (25-40m total)

NIGHTLY (2 AM UTC) → 8-phase comprehensive + data quality validation
  Phase 1: Unit tests
  Phase 2: Property-based tests
  Phase 3: Integration tests
  Phase 4: E2E tests
  Phase 5: ML model tests
  Phase 6: Risk management
  Phase 7: Coverage (95%+ target)
  Phase 8: Performance benchmarks

Critical Gaps

Gap	Impact	Priority	Fix Time
No regression suite	225 features untested	HIGH	4-6 hours
E2E tests failing	Service validation blocked	HIGH	2-4 hours
Wave D not continuous	Regime features not validated	MEDIUM	2-3 hours
No performance dashboard	Metrics not tracked	MEDIUM	4-6 hours

---

Immediate Action Items (1-2 weeks)

1. Fix E2E Tests (2-4 hours)

   • Resolve proto schema mismatches
   • Enable five-service orchestration validation
   • File: .github/workflows/e2e-ensemble-tests.yml

2. Add Nightly Regression Backtest (4-6 hours)

   • Create: .github/workflows/nightly-backtest-regression.yml
   • Wave C (201 features) vs Wave D (225 features)
   • Alert if >5% regression
   • Runtime: 4-6 hours execution

3. Enable Feature Validation (2-3 hours)

   • Add all 225 features to backtest
   • Verify regime detection integration (Wave D)
   • Add to comprehensive testing job
