""" Async order tracking and real-time monitoring for ProjectX. Author: @TexasCoding Date: 2025-08-02 Overview: Implements mixin logic for tracking order status, maintaining local state and cache, and handling real-time updates from websocket events. Supports callback registration for fills/cancels, cache queries, and system health validation. Key Features: - Real-time tracking via websocket/callbacks and local cache - Order-to-position relationship mapping - Async event/callback system for fills, cancels, rejections - Cache clearing, health/status reporting, and metrics - Integrates with OrderManager main class - WebSocket-based order status updates - Local caching for performance optimization - Comprehensive order lifecycle monitoring Real-time Tracking Capabilities: - Immediate order status change detection - Fill and cancellation event processing - Order-to-position relationship tracking - Custom callback registration for events - Cache-based performance optimization - Health monitoring and validation Example Usage: ```python # Assuming om is an instance of OrderManager await om.initialize(realtime_client) tracked = await om.get_tracked_order_status("12345") # Register callback for order events def on_order_fill(order_data): print(f"Order {order_data['id']} filled!") om.add_callback("order_fill", on_order_fill) ``` See Also: - `order_manager.core.OrderManager` - `order_manager.position_orders` - `order_manager.utils` """ import asyncio import logging import time from collections import defaultdict, deque from collections.abc import Callable, Coroutine from typing import TYPE_CHECKING, Any, cast from cachetools import TTLCache from project_x_py.types.trading import OrderStatus from project_x_py.utils.deprecation import deprecated if TYPE_CHECKING: from project_x_py.event_bus import EventBus from project_x_py.types import OrderManagerProtocol logger = logging.getLogger(__name__) class OrderTrackingMixin: """ Mixin for order tracking and real-time monitoring functionality.
