Configuration for the Hurst/VPIN directional strategy.

Combines a rescaled-range Hurst regime filter on dollar bars with a VPIN-derived informed-flow signal, and gates entry timing on the live quote stream.

Fields

base: StrategyConfig

Base strategy configuration.

instrument_id: InstrumentId

Instrument to subscribe to and trade.

bar_type: BarType

Dollar bar type (value aggregation sourced from trades).

trade_size: Quantity

Order quantity for each entry.

hurst_window: usize

Rolling window of dollar bar returns used to estimate the Hurst exponent.

hurst_lags: Vec<usize>

Lag set used for rescaled range regression.

hurst_enter: f64

Hurst threshold for entering a position (trending regime).

hurst_exit: f64

Hurst threshold for exiting an open position (regime decay).

vpin_window: usize

Number of completed volume buckets averaged for VPIN.

vpin_threshold: f64

Minimum VPIN value required to treat a bucket imbalance as informed flow.

max_holding_secs: u64

Maximum time (seconds) a position is held before forced flatten.

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker
