Struct hftbacktest::backtest::MultiAssetSingleExchangeBacktest

pub struct MultiAssetSingleExchangeBacktest<MD, Local, Exchange> { /* private fields */ }

Available on crate feature backtest only.

This backtester provides multi-asset and single-exchange model backtesting, meaning all assets have the same setups for models such as asset type or queue model. However, this can be slightly faster than Backtest. If you need to configure different models for each asset, use Backtest.

where MD: MarketDepth, Local: LocalProcessor<MD, Event>, Exchange: Processor,

pub fn builder() -> MultiAssetSingleExchangeBacktestBuilder<Local, Exchange>

pub fn new(local: Vec<Local>, exch: Vec<Exchange>) -> Self

Trait Implementations

impl<MD, Local, Exchange> Bot<MD> for MultiAssetSingleExchangeBacktest<MD, Local, Exchange>

where MD: MarketDepth, Local: LocalProcessor<MD, Event>, Exchange: Processor,

type Error = BacktestError

fn current_timestamp(&self) -> i64

In backtesting, this timestamp reflects the time at which the backtesting is conducted within the provided data. In a live bot, it’s literally the current local timestamp.

fn num_assets(&self) -> usize

Returns the number of assets.

fn position(&self, asset_no: usize) -> f64

Returns the position you currently hold.

fn state_values(&self, asset_no: usize) -> &StateValues

Returns the state’s values such as balance, fee, and so on.

fn depth(&self, asset_no: usize) -> &MD

Returns the MarketDepth.

fn last_trades(&self, asset_no: usize) -> &[Event]

Returns the last market trades.

fn clear_last_trades(&mut self, asset_no: Option<usize>)

Clears the last market trades from the buffer.

fn orders(&self, asset_no: usize) -> &HashMap<OrderId, Order>

Returns a hash map of order IDs and their corresponding Orders.

fn submit_buy_order( &mut self, asset_no: usize, order_id: OrderId, price: f64, qty: f64, time_in_force: TimeInForce, order_type: OrdType, wait: bool, ) -> Result<bool, Self::Error>

Places a buy order.

fn submit_sell_order( &mut self, asset_no: usize, order_id: OrderId, price: f64, qty: f64, time_in_force: TimeInForce, order_type: OrdType, wait: bool, ) -> Result<bool, Self::Error>

Places a sell order.

fn submit_order( &mut self, asset_no: usize, order: OrderRequest, wait: bool, ) -> Result<bool, Self::Error>

Places an order.

fn cancel( &mut self, asset_no: usize, order_id: OrderId, wait: bool, ) -> Result<bool, Self::Error>

Cancels the specified order.

fn clear_inactive_orders(&mut self, asset_no: Option<usize>)

Clears inactive orders from the local orders whose status is neither Status::New nor Status::PartiallyFilled.

fn wait_order_response( &mut self, asset_no: usize, order_id: OrderId, timeout: i64, ) -> Result<bool, BacktestError>

Waits for the response of the order with the given order ID until timeout.

fn wait_next_feed( &mut self, include_order_resp: bool, timeout: i64, ) -> Result<bool, Self::Error>

Wait until the next feed is received, or until timeout.

fn elapse(&mut self, duration: i64) -> Result<bool, Self::Error>

Elapses the specified duration.

fn elapse_bt(&mut self, duration: i64) -> Result<bool, Self::Error>

Elapses time only in backtesting. In live mode, it is ignored.

fn close(&mut self) -> Result<(), Self::Error>

Closes this backtester or bot.

fn feed_latency(&self, asset_no: usize) -> Option<(i64, i64)>

Returns the last feed’s exchange timestamp and local receipt timestamp.

fn order_latency(&self, asset_no: usize) -> Option<(i64, i64, i64)>

Returns the last order’s request timestamp, exchange timestamp, and response receipt timestamp.
