Struct StrategyCore 

pub struct StrategyCore {
    pub config: StrategyConfig,
    /* private fields */
}

The core component of a Strategy, managing data, orders, and state.

This struct is intended to be held as a member within a user’s custom strategy struct. Use the nautilus_strategy! macro to provide the trait accessors required by Strategy, StrategyNative, and DataActor. It does not deref to [DataActorCore]; normal strategy logic should use facade methods on the strategy value.

Fields

config: StrategyConfig

The strategy configuration.

Implementations

impl StrategyCore

pub fn new(config: StrategyConfig) -> Self

Creates a new StrategyCore instance.

pub fn config(&self) -> &StrategyConfig

Returns the strategy configuration.

pub fn change_id(&mut self, strategy_id: StrategyId)

Changes the strategy ID before registration.

pub fn change_order_id_tag(&mut self, order_id_tag: &str)

Changes the order ID tag before registration.

pub fn order_id_tag(&self) -> Option<&str>

Returns the runtime order ID tag.

pub fn strategy_id(&self) -> Option<StrategyId>

Returns the runtime strategy ID.

pub fn register( &mut self, trader_id: TraderId, clock: Rc<RefCell<dyn Clock>>, cache: Rc<RefCell<Cache>>, portfolio: Rc<RefCell<Portfolio>>, ) -> Result<()>

Registers the strategy with the trading engine components.

This is typically called by the framework when the strategy is added to an engine.

Errors

Returns an error if registration with the actor core fails.

pub fn order(&self) -> OrderApi<'_>

Returns the user-facing order creation API.

Panics

Panics if the strategy has not been registered.

pub fn reset_market_exit_state(&mut self)

Resets the market exit state.

Trait Implementations
