Struct IncrementalRsi 

pub struct IncrementalRsi { /* private fields */ }

Incremental RSI — O(1) per-tick, EMA-smoothed gains/losses.

Mirrors the batch rsi: the average gain and loss are tracked with an IncrementalEma of the given period and combined as 100 - 100 / (1 + avg_gain / avg_loss) (RSI is 100 when the average loss is zero). Like the other incremental structs it seeds from the first sample (vs. the batch SMA warm-up), so warm-up values differ slightly from rsi but converge — both are valid.

Implementations

impl IncrementalRsi

pub fn new(period: usize) -> Self

Create an incremental RSI for the given period.

pub fn update(&mut self, price: f64) -> Option<f64>

Feed the next price; returns the updated RSI, or None for the very first sample (RSI needs a prior price to form the first change).
