pub struct PlaybookEngine { /* private fields */ }

Implementations

impl PlaybookEngine

pub fn new( symbol: String, strategy_group: StrategyGroup, executor: Box<dyn OrderExecutor>, ) -> Self

pub fn new_with_risk_config( symbol: String, strategy_group: StrategyGroup, executor: Box<dyn OrderExecutor>, risk_config: Option<RiskConfig>, ) -> Self

Create an engine that wraps the executor with risk checks.

If risk_config is Some, the executor is wrapped in a RiskCheckedOrderExecutor so every order goes through pre-trade risk validation. If None, the inner executor is used directly (identical to Self::new).

pub fn fsm_state(&self) -> &PlaybookState

Return current FSM state (for external inspection / tests).

pub async fn tick_snapshot( &mut self, snapshot: &TaSnapshot, now: u64, ) -> TickResult

Tick with a TaSnapshot (new API). Converts to TechnicalIndicators internally via snapshot_to_indicators.

pub async fn tick( &mut self, indicators: &TechnicalIndicators, now: u64, ) -> TickResult

Core tick — called once per interval.
