Two new indicators in a brand-new "Ichimoku & alternative charts"
family:
- `Ichimoku` (Ichimoku Kinko Hyo): the full five-line cloud system
(Tenkan-sen, Kijun-sen, Senkou Span A/B, Chikou Span). Classic
(9, 26, 52, 26) defaults; configurable. Forward displacement is
handled in an O(1) ring buffer so the visible Senkou A/B at bar n
are the values computed at bar n-displacement.
- `HeikinAshi`: recursive candle smoothing transform emitting a
four-field synthetic candle. Seeds ha_open from (open+close)/2 on
the first bar.
Touchpoints: core + unit tests, mod.rs/lib.rs re-exports, Python +
Node + WASM bindings (multi-output via PyArray2 / interleaved Vec<f64>
/ Object+Float64Array), Python tests across smoke/new-indicators/
input-validation, Node parity tests, fuzz target (Candle), benches,
README family table + counter (71 -> 73, 8 -> 9 families), CHANGELOG.
Note: Renko, Kagi, and Point & Figure from the family-13 ideas list
are intentionally skipped. They are bar generators (the bar boundary
is defined by price moves, not by a fixed time interval) rather than
indicators that consume a candle stream, and belong in wickra-data
as candle/tick transforms alongside the existing tick-to-candle
aggregator and resampler.
