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.
Completes the F2 family (Advanced MAs) end to end:
- Rust core: zlema.rs (Zero-Lag EMA over the de-lagged series
2·price − price[lag]), t3.rs (Tillson's six-EMA cascade with the
volume-factor polynomial), vwma.rs (volume-weighted rolling mean with
a zero-volume fallback to the unweighted mean). Each with a full
Indicator impl, runnable doctest and reference-value / warmup /
reset / batch==streaming / non-finite tests.
- Python: PyZlema / PyT3 / PyVwma PyO3 classes + module registration
+ .pyi stubs (T3 defaults v=0.7).
- Node: ZlemaNode via the scalar macro, explicit T3Node and VwmaNode
classes; index.d.ts and index.js updated.
- WASM: WasmZlema / WasmT3 via the scalar macro, explicit WasmVwma.
- Wiki: Indicator-Zlema.md, Indicator-T3.md, Indicator-Vwma.md plus
rows in Indicators-Overview.md and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 232 core tests,
25 data tests and 33 doctests green.
Completes the F1 family (Simple & Weighted MAs). The Rust core for both
SMMA (Wilder's RMA) and TRIMA (triangular MA) already landed; this adds
the remaining Definition-of-Done steps:
- Python: PySmma / PyTrima PyO3 classes + module registration + .pyi stubs.
- Node: SmmaNode / TrimaNode via the scalar-indicator macro; index.d.ts
and index.js updated for the two new classes.
- WASM: WasmSmma / WasmTrima via the scalar-indicator macro.
- Wiki: Indicator-Smma.md and Indicator-Trima.md (full pages) plus rows
in Indicators-Overview.md and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 208 core tests,
25 data tests and 31 doctests green.
RollingVwap is a separate public type (pub struct RollingVwap in
vwap.rs) and Indicator-Vwap.md already documents it in a full
"## RollingVwap (finite window)" section, but it was not directly
reachable: the Overview row added in E12 pointed at a #rollingvwap
anchor that does not exist.
Fix the Overview link to the real #rollingvwap-finite-window anchor and
add a jump-to note at the top of Indicator-Vwap.md so both public types
are reachable in one click.
A5 changed Keltner and HMA to feed their sibling sub-indicators
unconditionally, so warmup_period() is now the exact first-emission
index for every indicator. The wiki still described the old
?-starvation behavior as correct.
- Indicator-Keltner.md: the Warmup section, the worked example output
(first emission now at i=2, not i=4), the summary table row, and the
"reported warmup understates" pitfall now state that warmup_period()
is exact. Example output regenerated by running the code.
- Indicator-Hma.md: the Warmup section, all three language examples
(first Some at index 10, not 13), the table row, and the chaining
pitfall corrected. Outputs regenerated.
- Indicators-Overview.md: dropped the claim that Hma and Kama lag their
reported warmup — both were verified exact.
Indicators-Overview.md referenced the absolute author-machine paths
D:\Coding\Wickra\crates\... and D:\Coding\Wickra\bindings\... in its
"Source-of-truth files" section, and seven trend-indicator pages had
Node examples that did require('D:/Coding/Wickra/bindings/node').
Replace the overview paths with repo-relative GitHub links and change
the Node examples to require('wickra'), the published npm package name
a reader would actually use. No D:/Coding path remains anywhere in docs.
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.
