Struct Rsi 

pub struct Rsi { /* private fields */ }

Relative Strength Index with a smoothed line, a signal line and a slower context line.

The raw RSI averages the up and down moves of the close over rsi_len changes — Wilder’s way by default, exponentially under RsiSmoothing::Ema — and is 100 - 100 / (1 + up / down), with 50 when nothing moved, 100 without down moves and 0 without up moves.

value is not that raw RSI. It is the line: an Ema(avg_len) over the raw RSI with the first-sample seed of the shared Ema, clamped to 0..=100. With the registry default avg_len = 3 the published RSI lags and deviates from the raw figure; avg_len = 1 gives the raw RSI itself.

extra["signal"]: Ema(sig_len) over the line. extra["ctx"]: the same construction over ctx_len changes (default 100), present once that many changes exist; divergences are judged between line and context. Alerts fire on line/signal crosses (inside the extreme zones when require_extreme_zone is set), on crosses of mid_line and on divergences.

First output: once rsi_len changes exist, i.e. with the rsi_len + 1-th bar. Indicator::reset clears all averages.

Implementations

impl Rsi

pub fn new( rsi_len: usize, avg_len: usize, sig_len: usize, mid_line: f64, overbought: f64, oversold: f64, lookback_extreme: usize, require_extreme_zone: bool, ctx_len: usize, div_len: usize, div_min: f64, ) -> Self

pub fn with_defaults() -> Self

pub fn with_period(rsi_len: usize) -> Self

pub fn with_smoothing(self, method: RsiSmoothing) -> Self

Selects how the up/down moves are smoothed; see RsiSmoothing.

Additive to the existing constructors, which keep the Wilder default. The choice applies to the main line and the context line — each with its own period (rsi_len/ctx_len) — so the divergence comparison is never between two differently smoothed series.

Resets the smoothing state, so this belongs before the first bar, not mid-series.
