2. **Line Movement**: Most books hide historical odds
3. **Disagreement Detection**: Automated value finder
4. **Sharp Money**: Professional betting signals
5. **Consensus**: True market price calculation
6. **Arbitrage**: Guaranteed profit opportunities
7. **Correlation**: Parlay mistake prevention
8. **Hedging**: Optimal hedge calculator

### Target Users
- **Casual Bettors**: Education + value detection
- **Serious Bettors**: Advanced analytics + CLV tracking
- **Professional Bettors**: Arbitrage + sharp money indicators
- **Sports Bettors**: All sports covered (NFL, NBA, NHL, MLB, NCAAF, NCAAB, Soccer)

## Next Steps

### Immediate Actions
1. **Review Issue Templates**: Validate technical approach
2. **Prioritize Features**: Confirm Phase 1 > Phase 2 > Phase 3 order
3. **Assign Team Members**: Backend, Frontend, QA leads
4. **Create Sprint Plan**: Break Phase 1 into 2-week sprints
5. **Set Up Project Board**: GitHub Projects for tracking

### Sprint 1 Recommendations (Start with CLV)
**Why CLV First?**
- Highest user value ("Am I beating closing odds?")
- Simplest to implement (just store closing odds)
- Foundation for other features (sharp money, disagreement)
- Immediate competitive advantage

**Sprint 1 Tasks**:
1. Create `CLVSnapshot` database model
2. Implement closing line capture service
3. Build CLV calculation algorithm
4. Create API endpoints (`/api/clv/*`)
5. Design CLV dashboard component
6. Add CLV to bet history page
7. Write unit tests
8. Deploy to staging

**Estimated Duration**: 6 days (2 weeks with testing)

### Long-term Roadmap
- **Month 1**: Phase 1 features (CLV, Line Movement, Disagreement)
- **Month 2**: Phase 2 features (Sharp Money, Consensus, Bookmaker Analytics)
- **Month 3**: Phase 3 features (Arbitrage, Correlation)
- **Month 4**: Polish, optimization, beta testing
