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.

  • Raises:
    • ValueError – If depth is negative (< 0).
    • ValueError – If interval_ms is not positive (> 0).

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.
