# Ralph Loop Progress - ib-flex Implementation
**Session**: 2026-01-12
**Task**: Implement plan for ib-flex Rust library
## Current Status
### Completed
- ✅ Phase 0: Project setup (Cargo.toml, README, licenses, directory structure)
- ✅ Initial project structure exists (src/, tests/, examples/, benches/)
- ✅ Basic enum stubs exist in src/types/common.rs
- ✅ Error types defined in src/error.rs
- ✅ Basic type stubs exist in src/types/activity.rs
### In Progress
- 🔄 Finding comprehensive FLEX XML examples for test fixtures
- Searched ibflex Python repo: https://github.com/csingley/ibflex
- Found: Minimal inline XML in tests, no external fixture files
- **Next**: Need to create realistic fixtures manually based on IB docs
### Not Started
- ❌ Complete all 15 enums in common.rs (5/15 done: AssetCategory, BuySell, OpenClose, OrderType, PutCall)
- ❌ Complete Trade struct with all 93 fields (partially done, ~30/93 fields)
- ❌ Complete other v0.1.0 types (OpenPosition, CashTransaction, CorporateAction, SecurityInfo, ConversionRate)
- ❌ Implement XML parser (currently returns unimplemented error)
- ❌ Create test fixtures
- ❌ Write integration tests
- ❌ Create example programs
- ❌ Benchmarks
- ❌ CI/CD setup
## Key Findings
### FLEX XML Examples
- ibflex Python library has minimal test fixtures
- Tests use programmatically generated XML elements
- Need to create fixtures based on:
1. IB FLEX documentation
2. Python ibflex Types.py (41 type definitions)
3. TYPES_ANALYSIS.md (comprehensive field lists)
### Missing Enums (10 more needed)
From TYPES_ANALYSIS.md, still need:
1. TradeType (ExchTrade, BookTrade, FracShare, etc.)
2. CashAction (Deposits, Dividends, Interest, Fees, etc.)
3. Reorg (Merger, Spinoff, Split, etc.)
4. OptionAction (Assignment, Exercise, Expiration, etc.)
5. TransferType (ACATS, ATON, FOP, INTERNAL)
6. Code (A, C, Ex, P, Ca, D, O - transaction codes)
7. ToFrom (To, From)
8. InOut (IN, OUT)
9. DeliveredReceived (Delivered, Received)
10. LongShort (Long, Short)
### Trade Struct Status
- Current: ~30 fields defined
- Target: 93 fields (see PLAN.md lines 479-592)
- Missing categories:
- Security identifiers (CUSIP, ISIN, FIGI, SEDOL, etc.)
- Derivative details
- Position tracking fields
- Commodity fields
- Many miscellaneous fields
## Next Actions (Priority Order)
1. **Create minimal realistic XML fixtures**
- Start with simple Activity FLEX with 1-2 trades
- Include all critical sections for v0.1.0
- Save to tests/fixtures/minimal_activity.xml
2. **Complete enum definitions**
- Add remaining 10 enums to common.rs
- Add comprehensive doc comments
- Add unit tests for each enum
3. **Complete Trade struct**
- Add all 93 fields from PLAN.md
- Ensure proper serde attributes
- Add doc comments for each field
4. **Implement parser**
- Use quick-xml with serde
- Handle XML structure: FlexQueryResponse > FlexStatements > FlexStatement
- Parse each section (Trades, Positions, etc.)
5. **Test-driven development**
- Write tests that parse minimal_activity.xml
- Iterate on types/parser until tests pass

## Files Modified This Session
1. `src/types/common.rs`
- Added more AssetCategory variants (Commodity, Warrant, Fund, Index)
## Notes for Next Session
- **Critical Path**: Need XML fixtures to drive implementation
- **Approach**: Start small (minimal fixture), grow iteratively
- **Testing**: Test-driven development - write tests first, implement to pass
- **Don't Overthink**: Create simple but realistic fixtures, don't need complete real-world data
