Trading

The trading subpackage groups all trading domain specific components and tooling.

This is a top-level package where the majority of users will interface with the framework. Custom trading strategies can be implemented by inheriting from the Strategy base class.

class Controller

The base class for all trader controllers.

Parameters:
- trader (Trader) – The reference to the trader instance to control.
- config (ActorConfig , optional) – The configuration for the controller

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.

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.

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

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.
