+///
+/// ```text
+/// long body = |close − open| >= 0.5 * (high − low) (bar1)
+/// doji = |close − open| <= 0.1 * (high − low) (bar2)
+/// bullish (+1.0): bar1 black, doji body gaps DOWN below it (max(o2,c2) < close1)
+/// bearish (−1.0): bar1 white, doji body gaps UP above it (min(o2,c2) > close1)
+/// ```
+///
+/// Output is `+1.0` (bullish star, after a black bar) or `−1.0` (bearish star,
+/// after a white bar) when the pattern completes, and `0.0` otherwise. The first
+/// bar always returns `0.0` because the two-bar window is not yet filled. Doji

+//! Rickshaw Man candlestick pattern.
+
+use crate::ohlcv::Candle;
+use crate::traits::Indicator;
+
+/// Rickshaw Man — a single-bar indecision signal. A long-legged doji whose tiny
+/// body sits near the *middle* of a wide range, the most balanced form of
+/// indecision: neither side controlled the close and the midpoint pins it.
+///
+/// ```text
+/// range = high − low
+/// doji = |close − open| <= 0.1 * range
+/// long upper = high − max(open, close) >= 0.3 * range
+/// long lower = min(open, close) − low >= 0.3 * range
+/// centred body = body midpoint within the central 40–60 % of the range
+/// ```
+///
+/// Output is `+1.0` when the rickshaw man prints and `0.0` otherwise. This is a
+/// non-directional indecision flag — it never emits `−1.0`. A rickshaw man is a
+/// special case of a long-legged doji (the body additionally sits at the centre),
+/// so both detectors may flag the same bar. Body and shadow thresholds follow the
+/// geometric house style (fixed fractions of the bar range) rather than TA-Lib's
+/// rolling averages. Pattern-shape check only — no trend filter is applied;
+/// combine with a trend indicator for actionable signals.
+///
+/// # Signed ±1 encoding
+///
+/// This detector emits the uniform candlestick sign convention shared across the
+/// pattern family — `+1.0` detected, `0.0` no pattern — so it drops straight into
+/// a machine-learning feature matrix as a single dimension.
+///
+/// # Example
+///
+/// ```
+/// use wickra_core::{Candle, Indicator, RickshawMan};
+///
+/// let mut indicator = RickshawMan::new();
+/// // Tiny body centred in a wide range, long shadows both sides.
+/// let candle = Candle::new(10.0, 12.0, 8.0, 10.0, 1.0, 0).unwrap();
+/// assert_eq!(indicator.update(candle), Some(1.0));
