//! Real Broker Integration Tests //! //! This module implements REAL integration tests with actual market data providers: //! - **Databento**: Real-time market data via WebSocket //! - **Benzinga**: Real-time news and sentiment data //! - **ICMarkets**: FIX protocol broker integration (demo account) //! - **Interactive Brokers**: TWS API integration (paper trading) //! //! ## Test Coverage: //! 1. **Connection Establishment**: Real authentication and connection setup //! 2. **Real-time Data Streams**: Market data, news, and execution feeds //! 3. **Order Management**: Submit, modify, cancel orders via real brokers //! 4. **Failover Scenarios**: Handle disconnections and reconnections //! 5. **Rate Limiting**: Respect API limits and implement backoff //! 6. **Data Quality**: Validate incoming data for completeness and accuracy //! 7. **Latency Measurement**: Real network latency to production systems //! 8. **Error Handling**: Robust error recovery and logging //! //! ## Environment Variables Required: //! - `DATABENTO_API_KEY`: Databento API key for market data //! - `BENZINGA_API_KEY`: Benzinga API key for news data //! - `ICMARKETS_DEMO_LOGIN`: ICMarkets demo account credentials //! - `INTERACTIVE_BROKERS_PAPER_ACCOUNT`: IB paper trading account //! - `ENABLE_REAL_BROKERS=true`: Enable actual broker connections //! //! ## Safety Features: //! - All orders use demo/paper trading accounts only //! - Strict position limits to prevent accidental large trades //! - Automatic cleanup of test positions //! - Rate limiting to respect broker API limits #![warn(missing_docs)] #![warn(clippy::all)] #![allow(clippy::too_many_arguments)] use std::collections::HashMap;
