This module defines a trading strategy class which allows users to implement their own customized trading strategies

A user can inherit from Strategy and optionally override any of the “on” named event methods. The class is not entirely initialized in a stand-alone way, the intended usage is to pass strategies to a Trader so that they can be fully “wired” into the platform. Exceptions will be raised if a Strategy attempts to operate without a managing Trader instance.

class Strategy

Bases: Actor

Strategy(config: StrategyConfig | None = None)

The base class for all trading strategies.

This class allows traders to implement their own customized trading strategies. A trading strategy can configure its own order management system type, which determines how positions are handled by the ExecutionEngine.

Strategy OMS (Order Management System) types: : - UNSPECIFIED: No specific type has been configured, will therefore default to the native OMS type for each venue.

• HEDGING: A position ID will be assigned for each new position which is opened per instrument.
• NETTING: There will only be a single position for the strategy per instrument. The position ID naming convention is {instrument_id}-{strategy_id}.

• Parameters: config (StrategyConfig , optional) – The trading strategy configuration.
• Raises: TypeError – If config is not of type StrategyConfig.

WARNING

• This class should not be used directly, but through a concrete subclass.
• Do not call components such as clock and logger in the __init__ prior to registration.
