trader.strategies.registry module

Build strategy instances from configuration.

The registry is the extension point: adding a strategy is one class plus one entry here, so the set of strategies stays a configuration concern rather than a code-structure one.

trader.strategies.registry.build_all(configs, *, llm=None, news_provider=None, decision_memory=None)

Instantiate every configured strategy, keyed by id.

Parameters:

• configs (Sequence[StrategyConfig])

• llm (object | None)

• news_provider (object | None)

• decision_memory (object | None)

Return type:

dict[str, Strategy]

trader.strategies.registry.build_strategy(config, *, llm=None, news_provider=None, decision_memory=None, alias_resolver=None, analyst_provider=None, earnings_provider=None)

Instantiate one configured strategy.

decision_memory is optional and only ever reaches an llm entry: a strategy built without one calls the model every cycle, which is the behaviour that existed before the news-fingerprint gate. Passing None is a valid, conservative configuration, not a degraded one.

Raises:

ConfigError – unknown type, a parameter the strategy does not accept, or an llm/trailing_stop_floor entry with no provider supplied.

Parameters:

• config (StrategyConfig)

• llm (object | None)

• news_provider (object | None)

• decision_memory (object | None)

• alias_resolver (object | None)

• analyst_provider (object | None)

• earnings_provider (object | None)

Return type:

Strategy
