First half of the eight indicators that fill out the new family taxonomy.
- Rust core: accelerator_oscillator.rs (AcceleratorOscillator — AO minus a
short SMA of itself), balance_of_power.rs (BalanceOfPower — per-bar
(close-open)/(high-low)), choppiness_index.rs (ChoppinessIndex — summed
true range over the high-low span, log-scaled) and
vertical_horizontal_filter.rs (VerticalHorizontalFilter — net move over
total move). Each with a full Indicator impl, runnable doctest and
reference / property / warmup / reset / batch==streaming tests.
- Python / Node / WASM: classes wired through all three bindings
(BalanceOfPower carries an explicit open column; VHF rides the scalar
macros) plus .pyi stubs and __init__.py / __all__ entries.
- Wiki: four new Indicator-*.md pages.
The eight-family taxonomy restructure (Overview / Home / README / folder
layout) lands in F13c once F13b's four indicators are in.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 481 core tests,
25 data tests and 70 doctests green.
Completes the F5 family (Price oscillators) end to end:
- Rust core: ppo.rs (Percentage Price Oscillator — MACD as a percentage
of the slow EMA), dpo.rs (Detrended Price Oscillator — shifted price
minus its SMA), coppock.rs (Coppock Curve — WMA of two summed ROCs).
Each with a full Indicator impl, runnable doctest and reference /
constant-series / warmup / reset / batch==streaming / non-finite tests.
- Python: PyPpo / PyDpo / PyCoppock PyO3 classes + module registration
+ .pyi stubs (defaults PPO=(12,26), DPO=20, Coppock=(14,11,10)).
- Node: DpoNode via the scalar macro, explicit PpoNode and CoppockNode;
index.d.ts and index.js updated.
- WASM: WasmDpo / WasmPpo / WasmCoppock via the scalar macro.
- Wiki: Indicator-Ppo/Dpo/Coppock.md plus rows in Indicators-Overview.md
and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 300 core tests,
25 data tests and 42 doctests green.
Completes the F4 family (Stochastic oscillators) end to end:
- Rust core: stoch_rsi.rs (Stochastic Oscillator applied to the RSI
series, bounded [0,100]) and ultimate_oscillator.rs (Larry Williams'
weighted three-timeframe buying-pressure oscillator). Each with a full
Indicator impl, runnable doctest and reference / saturation / bounds /
warmup / reset / batch==streaming tests.
- Python: PyStochRsi / PyUltimateOscillator PyO3 classes + module
registration + .pyi stubs (defaults StochRSI=(14,14), UO=(7,14,28)).
- Node: explicit StochRsiNode and UltimateOscillatorNode; index.d.ts
and index.js updated.
- WASM: WasmStochRsi via the scalar macro, explicit
WasmUltimateOscillator.
- Wiki: Indicator-StochRsi.md and Indicator-UltimateOscillator.md plus
rows in Indicators-Overview.md and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 278 core tests,
25 data tests and 39 doctests green.
The 33 Markdown files under docs/wiki/ were never tracked. Commit them
into the repository so the documentation is versioned alongside the
code: 8 top-level pages plus 25 per-indicator deep dives under
indicators/{momentum,trend,volatility,volume}/.
The pages are kept in-repo (not pushed to a flat GitHub Wiki), so the
relative indicators/<family>/... links in Home.md resolve correctly
when rendered on GitHub.
