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.
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.
