Struct CloseMidpointDiff 

pub struct CloseMidpointDiff { /* private fields */ }

Close-Midpoint Difference — close - (high + low) / 2.

Measures where the close lands relative to the center of the bar’s range:

• Positive: close is above the midpoint (bullish close within the bar).
• Negative: close is below the midpoint (bearish close within the bar).
• Zero: close exactly at the midpoint.

This is a period-1 indicator that emits on every bar.

Example

use fin_primitives::signals::indicators::CloseMidpointDiff;
use fin_primitives::signals::Signal;
let cmd = CloseMidpointDiff::new("cmd");
assert_eq!(cmd.period(), 1);

Implementations

impl CloseMidpointDiff

pub fn new(name: impl Into<String>) -> Self

Constructs a new CloseMidpointDiff.

Trait Implementations

impl Signal for CloseMidpointDiff

fn name(&self) -> &str

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

fn period(&self) -> usize

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

fn is_ready(&self) -> bool

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

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

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

fn reset(&mut self)

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

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.
