Struct FlagPennant 

pub struct FlagPennant { /* private fields */ }

Flag / Pennant — a brief consolidation against a sharp prior move (the “pole”), resolving in the pole’s direction.

Built on confirmed swing pivots ([SWING_THRESHOLD] = 5%); evaluated from the last three pivots pole_start → pole_end → consolidation:

pole      = |pole_end − pole_start|     (the sharp impulse)
pullback  = |consolidation − pole_end|  (the shallow counter-move)
qualifies when pullback < 0.5 · pole
bull flag : pole_end is a swing high → +1 (up-pole, continuation up)
bear flag : pole_end is a swing low  → -1 (down-pole, continuation down)

The detector fires on the bar that confirms the consolidation pivot (the flag is complete; the breakout is expected to follow). Output is +1.0 / -1.0 / 0.0; never None.

Implementations

impl FlagPennant

pub const fn new() -> Self

Construct a new Flag / Pennant detector.

Trait Implementations

impl Clone for FlagPennant

fn clone(&self) -> FlagPennant

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlagPennant

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FlagPennant

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for FlagPennant

type Input = Candle

Type of one input data point (typically f64 for a price, or Candle / Tick).

type Output = f64

Type of one output value.

fn update(&mut self, candle: Candle) -> Option<f64>

Feed one new data point into the indicator and return the freshly computed output, or None if the indicator is still warming up.

fn reset(&mut self)

Reset all internal state, leaving the indicator equivalent to a freshly constructed instance with the same parameters.

fn warmup_period(&self) -> usize

Number of inputs required before the first non-None output can be produced.

fn is_ready(&self) -> bool

Whether the indicator has emitted at least one value since the last reset.

fn name(&self) -> &'static str

Stable, human-readable indicator name. Used by chaining and diagnostics.
