//! # Order Management
//!
//! This module provides comprehensive order management capabilities including
//! order creation, modification, cancellation, and execution tracking.
//! It supports various order types and advanced trading features.
//!
//! ## Features
//!
//! - **Order Placement**: Submit market, limit, stop, and other order types
//! - **Order Modification**: Modify existing orders with new parameters
//! - **Order Cancellation**: Cancel individual orders or all open orders
//! - **Execution Tracking**: Monitor order fills and execution details
//! - **Commission Reports**: Track commission charges for executed trades
//! - **Order Status Updates**: Real-time updates on order state changes
//!
//! ## Order Types
//!
//! The module supports various order types including:
//! - Market orders
//! - Limit orders
//! - Stop orders
//! - Stop-limit orders
//! - Trailing stop orders
//! - VWAP/TWAP algorithmic orders
//! - And many more specialized order types
//!
//! ## Usage
//!
//! Orders are created using the `Order` struct and can be customized with various
//! parameters. The `order_builder` module provides a fluent API for constructing
//! complex orders.
