feat: add opt-in validate_symbol parameter to order creation#467
Merged
Conversation
Add validate_symbol parameter (default False) to create_limit_order and create_order in Context and TradingStrategy. When enabled, validates the target_symbol against registered data sources and portfolio positions, raising OperationalException for unknown symbols. Closes #247
Remove symbol format construction from _validate_target_symbol. Validation now does a simple direct comparison of target_symbol against registered data source symbols. The framework should not guess or construct symbol formats. Updates tests to use exact data source symbols.
…mbol (#247) validate_symbol now only prevents nonsensical orders where target_symbol equals trading_symbol (e.g. EUR/EUR). No data source lookups or symbol format construction needed.
validate_symbol now checks two things: 1. target_symbol != trading_symbol (prevents EUR/EUR) 2. A data source is registered for the target_symbol/trading_symbol combination (e.g. BTC/EUR) to ensure price history tracking
