Struct SupportTestCount 

pub struct SupportTestCount { /* private fields */ }

Rolling count of bars whose low is within 0.5% of the period’s lowest low.

Measures how many times price has tested the support level in the recent window. Higher counts suggest a stronger, well-tested support zone.

Implementations

impl SupportTestCount

pub fn new(period: usize, threshold_pct: Decimal) -> Result<Self, FinError>

Creates a new SupportTestCount with the given rolling period and threshold percentage.

Trait Implementations

impl Signal for SupportTestCount

fn update(&mut self, bar: &BarInput) -> Result<SignalValue, FinError>

Updates the signal with a BarInput and returns the current value.

fn is_ready(&self) -> bool

Returns true if the signal has accumulated enough bars to produce a value.

fn period(&self) -> usize

Returns the number of bars required before the signal produces a value.

fn reset(&mut self)

Resets the signal to its initial state as if no bars had been seen.

fn name(&self) -> &str

Returns the name of this signal (unique within a pipeline).

fn update_bar(&mut self, bar: &OhlcvBar) -> Result<SignalValue, FinError>

Convenience wrapper: converts bar to BarInput and calls Self::update.

fn warm_up(&mut self, bars: &[BarInput]) -> Result<SignalValue, FinError>

Feed a slice of historical bars to prime the indicator in one call.
