Resolves issue where sell proceeds were not immediately available for
subsequent buy orders within the same trading session.
Problem:
- Both buy() and sell() independently queried database for starting position
- Multiple trades within same day all saw pre-trade cash balance
- Agents couldn't rebalance portfolios (sell + buy) in single session
Solution:
- ContextInjector maintains in-memory position state during trading session
- Position updates accumulate after each successful trade
- Position state injected into buy/sell via _current_position parameter
- Reset position state at start of each trading day
Changes:
- agent/context_injector.py: Add position tracking with reset_position()
- agent_tools/tool_trade.py: Accept _current_position in buy/sell functions
- agent/base_agent/base_agent.py: Reset position state daily
- tests: Add 13 comprehensive tests for position tracking
All new tests pass. Backward compatible, no schema changes required.
**Problem:**
Final positions showed empty holdings despite executing 15+ trades.
The issue persisted even after fixing the get_current_position_from_db query.
**Root Cause:**
At end of trading day, base_agent.py line 672 called
_get_current_portfolio_state() which queried the database for current
position. On the FIRST trading day, this query returns empty holdings
because there's no previous day's record.
**Why the Previous Fix Wasn't Enough:**
The previous fix (date < instead of date <=) correctly retrieves
STARTING position for subsequent days, but didn't address END-OF-DAY
position calculation, which needs to account for trades executed
during the current session.
**Solution:**
Added new method _calculate_final_position_from_actions() that:
1. Gets starting holdings from previous day (via get_starting_holdings)
2. Gets all actions from actions table for current trading day
3. Applies each buy/sell to calculate final state:
- Buy: holdings[symbol] += qty, cash -= qty * price
- Sell: holdings[symbol] -= qty, cash += qty * price
4. Returns accurate final holdings and cash
**Impact:**
- First trading day: Correctly saves all executed trades as final holdings
- Subsequent days: Final position reflects all trades from that day
- Holdings now persist correctly across all trading days
**Tests:**
- test_calculate_final_position_first_day_with_trades: 15 trades on first day
- test_calculate_final_position_with_previous_holdings: Multi-day scenario
- test_calculate_final_position_no_trades: No-trade edge case
All tests pass ✅
**Problem:**
Subsequent trading days were not retrieving starting holdings correctly.
The API showed empty starting_position and final_position even after
executing multiple buy trades.
**Root Cause:**
get_current_position_from_db() used `date <= ?` which returned the
CURRENT day's trading_day record instead of the PREVIOUS day's ending.
Since holdings are written at END of trading day, querying the current
day's record would return incomplete/empty holdings.
**Timeline on Day 1 (2025-10-02):**
1. Start: Create trading_day with empty holdings
2. Trade: Execute 8 buy trades (recorded in actions table)
3. End: Call get_current_position_from_db(date='2025-10-02')
- Query: `date <= 2025-10-02` returns TODAY's record
- Holdings: EMPTY (not written yet)
- Saves: Empty holdings to database ❌
**Solution:**
Changed query to use `date < ?` to retrieve PREVIOUS day's ending
position, which becomes the current day's starting position.
**Impact:**
- Day 1: Correctly saves ending holdings after trades
- Day 2+: Correctly retrieves previous day's ending as starting position
- Holdings now persist between trading days as expected
**Tests Added:**
- test_get_position_retrieves_previous_day_not_current: Verifies query
returns previous day when multiple days exist
- Updated existing tests to align with new behavior
Fixes holdings persistence bug identified in API response showing
empty starting_position/final_position despite successful trades.
- Removed test files for old schema (reasoning_e2e, position_tracking_bugs)
- Updated test_database.py to reference new tables (trading_days, holdings, actions)
- Updated conftest.py to clean new schema tables
- Fixed index name assertions to match new schema
- Updated table count expectations (9 tables in new schema)
Known issues:
- Some cascade delete tests fail (trading_days FK doesn't have ON DELETE CASCADE)
- Database locking issues in some test scenarios
- These will be addressed in future cleanup
- Created migration script to drop old tables
- Removed old table creation from database.py
- Added tests to verify old tables are removed and new tables exist
- Migration script can be run standalone with: PYTHONPATH=. python api/migrations/002_drop_old_schema.py
- Delete Pydantic models: ReasoningMessage, PositionSummary, TradingSessionResponse, ReasoningResponse
- Delete /reasoning endpoint from api/main.py
- Remove /reasoning documentation from API_REFERENCE.md
- Delete old endpoint tests (test_api_reasoning_endpoint.py)
- Add integration tests verifying /results replaces /reasoning
The /reasoning endpoint has been replaced by /results with reasoning parameter:
- GET /reasoning?job_id=X -> GET /results?job_id=X&reasoning=summary
- GET /reasoning?job_id=X&include_full_conversation=true -> GET /results?job_id=X&reasoning=full
Benefits of new endpoint:
- Day-centric structure (easier to understand portfolio progression)
- Daily P&L metrics included
- AI-generated reasoning summaries
- Unified data model (trading_days, actions, holdings)
Changes:
- Write TRADING_DAY_ID to runtime config after creating trading_day record in BaseAgent
- Fix datetime deprecation warnings by replacing datetime.utcnow() with datetime.now(timezone.utc)
- Add test for trading_day_id=None fallback path to verify runtime config lookup works correctly
This ensures trade tools can access trading_day_id from runtime config when not explicitly passed.
This commit implements Task 1 from the schema migration plan:
- Trade tools (buy/sell) now write to actions table instead of old positions table
- Added trading_day_id parameter to buy/sell functions
- Updated ContextInjector to inject trading_day_id
- Updated RuntimeConfigManager to include TRADING_DAY_ID in config
- Removed P&L calculation from trade functions (now done at trading_days level)
- Added tests verifying correct behavior with new schema
Changes:
- agent_tools/tool_trade.py: Modified _buy_impl and _sell_impl to write to actions table
- agent/context_injector.py: Added trading_day_id parameter and injection logic
- api/model_day_executor.py: Updated to read trading_day_id from runtime config
- api/runtime_manager.py: Added trading_day_id to config initialization
- tests/unit/test_trade_tools_new_schema.py: New tests for new schema compliance
All tests passing.

process for local development, CI/CD, and pull request workflows.
- Updated create_mock_agent() to remove references to deleted methods (get_positions, get_last_trade, get_current_prices)
- Replaced position/holdings write tests with initial position creation test
- Added set_context AsyncMock to properly test async agent flow
- Skipped deprecated tests that verified removed _write_results_to_db() and _calculate_portfolio_value() methods
- All model_day_executor tests now pass (11 passed, 3 skipped)
- Create tests/unit/test_position_tracking_bugs.py with three test cases
- test_cash_not_reset_between_days: Tests that cash carries over between days
- test_positions_persist_over_weekend: Tests that positions persist across non-trading days
- test_profit_calculation_accuracy: Tests that profit calculations are accurate
Note: These tests currently PASS, which indicates either:
1. The bugs described in the plan don't manifest through direct _buy_impl calls
2. The bugs only occur when going through ModelDayExecutor._write_results_to_db()
3. The trade tools are working correctly, but ModelDayExecutor creates corrupt records
The tests validate the CORRECT behavior. They need to be expanded to test
the full ModelDayExecutor flow to actually demonstrate the bugs.

All 11 tests passing.
Fix two failing unit tests by making mock executors properly simulate
the job detail status updates that real ModelDayExecutor performs:
- test_run_updates_job_status_to_completed
- test_run_handles_partial_failure
Root cause: Tests mocked ModelDayExecutor but didn't simulate the
update_job_detail_status() calls. The implementation relies on these
calls to automatically transition job status from pending to
completed/partial/failed.
Solution: Mock executors now call manager.update_job_detail_status()
to properly simulate the status update lifecycle:
1. Update to "running" when execution starts
2. Update to "completed" or "failed" when execution finishes
This matches the real ModelDayExecutor behavior and allows the
automatic job status transition logic in JobManager to work correctly.
Update existing simulation_worker unit tests to account for new _prepare_data integration:
- Mock _prepare_data to return available dates
- Update mock executors to return proper result dicts with model/date fields
Note: Some tests need additional work to properly verify job status updates.
