Struct BacktestEngine 

pub struct BacktestEngine<S: Signal> { /* private fields */ }

Builder for configuring and executing a backtest simulation. Encapsulates the configuration, database connection, operator, and time range for the backtest. The simulation is started when start is called, returning a BacktestController for monitoring progress.

Implementations

impl<S: Signal> BacktestEngine<S>

pub async fn with_signal_operator( config: BacktestConfig, db: Arc<Database>, evaluators: Vec<Box<dyn SignalEvaluator<S>>>, signal_operator: Box<dyn SignalOperator<S>>, start_time: DateTime<Utc>, start_balance: u64, end_time: DateTime<Utc>, ) -> Result<Self, BacktestError>

Creates a new backtest engine using signal-based evaluation. Signal evaluators generate trading signals that are processed by the signal operator to execute trading actions.

The generic parameter S ensures type safety between evaluators and operator. They must produce and consume the same signal type.

pub fn start_time(&self) -> DateTime<Utc>

Returns the start time of the backtest simulation period.

pub fn start_balance(&self) -> u64

Returns the starting balance (in satoshis) for the backtest simulation.

pub fn end_time(&self) -> DateTime<Utc>

Returns the end time of the backtest simulation period.

pub fn receiver(&self) -> BacktestReceiver

Creates a new receiver for subscribing to backtest status and trading state updates.

pub fn start(self) -> Arc<BacktestController>

Starts the backtest simulation and returns a BacktestController for managing it. This consumes the engine and spawns the backtest task in the background.

impl BacktestEngine<Raw>

pub async fn with_raw_operator( config: BacktestConfig, db: Arc<Database>, raw_operator: Box<dyn RawOperator>, start_time: DateTime<Utc>, start_balance: u64, end_time: DateTime<Utc>, ) -> Result<Self, BacktestError>

Creates a new backtest engine using a raw operator. The raw operator directly implements trading logic without intermediate signal generation.
