Struct RangeMidpointPosition 

pub struct RangeMidpointPosition { /* private fields */ }

Range Midpoint Position — (close - midpoint) / half_range normalized to [-1, 1].

Computes the N-period high/low midpoint and measures where the close sits:

• +1.0: close at the period high.
• 0.0: close at the midpoint of the period range.
• -1.0: close at the period low.

Returns SignalValue::Unavailable until period bars have been accumulated, or when high == low (zero range).

Errors

Returns FinError::InvalidPeriod if period == 0.

Example

use fin_primitives::signals::indicators::RangeMidpointPosition;
use fin_primitives::signals::Signal;
let rmp = RangeMidpointPosition::new("rmp_20", 20).unwrap();
assert_eq!(rmp.period(), 20);

Implementations

impl RangeMidpointPosition

pub fn new(name: impl Into<String>, period: usize) -> Result<Self, FinError>

Constructs a new RangeMidpointPosition.

Errors

Returns FinError::InvalidPeriod if period == 0.

Trait Implementations

impl Signal for RangeMidpointPosition

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.
