Broker configurations are managed through the central config system: +//! +//! ```toml +//! [data.interactive_brokers] +//! host = "127.0.0.1" +//! port = 7497 +//! client_id = 1 +//! timeout_seconds = 30 +//! +//! [data.icmarkets] +//! host = "fix-demo.icmarkets.com" +//! port = 9880 +//! username = "${ICMARKETS_USERNAME}" +//! password = "${ICMARKETS_PASSWORD}" +//! ``` +//! +//! ## Error Handling +//! +//! All broker operations return `Result` for consistent error +//! handling across different broker implementations. +//! +//! ## Performance Considerations +//! +//! - **Connection Pooling**: Reuse connections where possible +//! - **Async Operations**: All I/O is non-blocking +//! - **Batching**: Group related operations to reduce latency +//! - **Circuit Breakers**: Automatic failover and recovery +//! +//! ## Architecture Note +//! +//!
