Struct EmaCrossConfigBuilder 

pub struct EmaCrossConfigBuilder<S: State = Empty> { /* private fields */ }

Use builder syntax to set the inputs and finish with build().

Implementations

impl<S: State> EmaCrossConfigBuilder<S>

pub fn build(self) -> EmaCrossConfig

where S: IsComplete,

Finish building and return the requested object

pub fn base(self, value: StrategyConfig) -> EmaCrossConfigBuilder<SetBase<S>>

where S::Base: IsUnset,

Optional (Some / Option setters). Default:

StrategyConfig {
    strategy_id: Some(StrategyId::from("EMA_CROSS-001")),
    order_id_tag: Some("001".to_string()),
    ..Default::default()
}

Base strategy configuration.

pub fn maybe_base( self, value: Option<StrategyConfig>, ) -> EmaCrossConfigBuilder<SetBase<S>>

where S::Base: IsUnset,

Optional (Some / Option setters). Default:

StrategyConfig {
    strategy_id: Some(StrategyId::from("EMA_CROSS-001")),
    order_id_tag: Some("001".to_string()),
    ..Default::default()
}

Base strategy configuration.

pub fn instrument_id( self, value: InstrumentId, ) -> EmaCrossConfigBuilder<SetInstrumentId<S>>

where S::InstrumentId: IsUnset,

Required.

Instrument to subscribe to and trade.

pub fn trade_size( self, value: Quantity, ) -> EmaCrossConfigBuilder<SetTradeSize<S>>

where S::TradeSize: IsUnset,

Required.

Order quantity for each crossover signal.

pub fn fast_period( self, value: usize, ) -> EmaCrossConfigBuilder<SetFastPeriod<S>>

where S::FastPeriod: IsUnset,

Optional (Some / Option setters). Default: 10.

Fast EMA period. Shorter periods react faster.

pub fn maybe_fast_period( self, value: Option<usize>, ) -> EmaCrossConfigBuilder<SetFastPeriod<S>>

where S::FastPeriod: IsUnset,

Optional (Some / Option setters). Default: 10.

Fast EMA period. Shorter periods react faster.

pub fn slow_period( self, value: usize, ) -> EmaCrossConfigBuilder<SetSlowPeriod<S>>

where S::SlowPeriod: IsUnset,

Optional (Some / Option setters). Default: 50.

Slow EMA period. Longer periods filter noise.

pub fn maybe_slow_period( self, value: Option<usize>, ) -> EmaCrossConfigBuilder<SetSlowPeriod<S>>

where S::SlowPeriod: IsUnset,

Optional (Some / Option setters). Default: 50.

Slow EMA period. Longer periods filter noise.
