}Expand description
Core interface for all streaming technical indicators.
Implementations should be stateful and cheap to next(). The default
calculate helper performs a streaming pass over a slice of candles.

Required Methods§
Sourcefn next(&mut self, candle: &Candle) -> Option<Self::Output>
fn next(&mut self, candle: &Candle) -> Option<Self::Output>
Feed one candle; returns Some(output) once warmup is satisfied, otherwise None.
Sourcefn warmup_period(&self) -> usize
fn warmup_period(&self) -> usize
Number of candles required before the first valid output.
Sourcefn clone_boxed(&self) -> Box<dyn Indicator<Output = Self::Output>>
fn clone_boxed(&self) -> Box<dyn Indicator<Output = Self::Output>>
Clone into a boxed trait object.
Provided Methods§
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
