Struct EmaCrossConfig 

pub struct EmaCrossConfig {
    pub base: StrategyConfig,
    pub instrument_id: InstrumentId,
    pub trade_size: Quantity,
    pub fast_period: usize,
    pub slow_period: usize,
}

Configuration for the dual-EMA crossover strategy.

Fields

base: StrategyConfig

Base strategy configuration.

instrument_id: InstrumentId

Instrument to subscribe to and trade.

trade_size: Quantity

Order quantity for each crossover signal.

fast_period: usize

Fast EMA period. Shorter periods react faster.

slow_period: usize

Slow EMA period. Longer periods filter noise.

type Layout = <<EmaCrossConfig as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<EmaCrossConfig>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = NoopThreadChecker

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForEmaCrossConfig

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<PyObjectOffset>
