This module provides a unified interface for interacting with various brokers
(Alpaca, IBKR, Paper) and managing order execution.

    - InvalidOrderError: Invalid order parameters
    - PositionError: Error with position operations
    - RateLimitError: Rate limit exceeded

    Abstract Base Class:
    - BrokerBase: Abstract base class for broker implementations

Example:
    >>> from tradingagents.execution import (
    ...     BrokerBase,
    ...     OrderRequest,
    ...     OrderSide,
    ...     OrderType,
    ... )
    >>>
    >>> # Create a market buy order
    >>> order_request = OrderRequest.market("AAPL", OrderSide.BUY, 100)
    >>>
    >>> # Or with more options
    >>> order_request = OrderRequest.limit(
    ...     symbol="AAPL",
    ...     side=OrderSide.BUY,
    ...     quantity=100,
    ...     limit_price=150.00,
    ... )
