Indicators-Overview.md listed RollingVwap as its own row in the Volume
table (count = 9, total = 72), but Home.md and README.md treat it as
a sub-variant of Vwap (count = 8, total = 71). Drop the standalone row
in Indicators-Overview and fold the rolling variant into the Vwap row.
Warmup-Periods.md keeps both constructors (Vwap::new() and
RollingVwap::new(n) have different warmup periods, which is the whole
purpose of that page) but adds a note explaining that the row count
exceeds the 71 canonical indicators by one.
The Quickstart-Node API-surface table claimed `warmupPeriod()` was
"not exposed on every multi-output class". After the B-series fixes
in `todo-detailed.md` and the R3/R8 pass on this branch, every Node
indicator class — single- and multi-output, scalar- and candle-input —
exposes `warmupPeriod()`. Updated the note accordingly.
The Quickstart-WASM page only mentioned `MACD` and `BollingerBands` as
multi-output indicators. After R3 (this branch) every candle-input
WASM class also exposes a structured `update`: `Stochastic`, `ADX`,
`Keltner`, `Donchian`, `Aroon` (plus `SuperTrend`, which has always
been there).
The "Multi-output indicators" section now lists every multi-output
shape in a table, and a short note at the end calls out the 0.1.5
parity: every candle-input indicator ships `update` / `batch` /
`reset` / `isReady` / `warmupPeriod`, so browser code doesn't need
to replay `batch` on each tick anymore.
Three indicator pages get a short follow-up paragraph that surfaces an
internal implementation detail the audit findings made user-visible:
- `Indicator-LinearRegression.md` gains a "Complexity" section explaining
the O(1) update (precomputed `Σx`, `Σxx`; incrementally slid `Σy`,
`Σxy` via the closed-form sliding identity), and the existing
"Reset" bullet mentions the additional running accumulators. The same
story applies to `LinRegSlope` and `LinRegAngle` (the page now links
to both rather than repeating the derivation three times).
- `Indicator-Sma.md` and `Indicator-BollingerBands.md` mention the
periodic reseed (`16 · period` updates) that caps floating-point
drift on long-running streams. Amortised cost is still O(1) and the
user-facing behaviour on benign inputs is unchanged.
No behavioural claim, no API claim, no example changes — just narrative
catching up with the implementation.
Versions bumped to 0.1.5 in every authoritative location:
- workspace `Cargo.toml` (`[workspace.package].version`, the
`wickra-core` path dependency pin).
- `bindings/python/pyproject.toml`.
- `bindings/node/package.json` (main + all six `optionalDependencies`
pins).
- All six per-platform `bindings/node/npm/<target>/package.json`
templates.
CHANGELOG: the accumulated `[Unreleased]` block is promoted to
`[0.1.5] - TBD` (date left for the user to set at tag time); the new
`[Unreleased]` header sits empty above it; the compare link table is
extended with `[0.1.5]: …compare/v0.1.4...v0.1.5` and the
`[Unreleased]` link is repointed to `…compare/v0.1.5...HEAD`.
Wiki refresh for 0.1.5 (R20 + Z2):
- `Home.md` version pin table updated; the Quickstart-Node hint replaces
the "spam filter holding back Windows" caveat with "0.1.5 is the
first release in which `npm install wickra` works end-to-end on
Windows" (npm Support released the name on 2026-05-22).
- `Quickstart-Node.md`'s Windows caveat is rewritten to explain the
history (`0.1.1`–`0.1.4` of `wickra-win32-x64-msvc` are burned) and
the resolution (0.1.5+ installs cleanly).
- `Quickstart-Rust.md` version mention bumped.
- `Warmup-Periods.md` note bumped + corrected: every Node and WASM
class — single- and multi-output — now exposes `warmupPeriod()` after
R3 (this branch), not only the single-output ones.
`release.yml` `publish_dir` no longer silently swallows a
second-attempt platform-package publish failure with a `::warning::`
and `return 0`. A real failure (after the existing 30s retry) now
emits an `::error::` and fails the job. The original mask is exactly
what allowed the `wickra-win32-x64-msvc@0.1.1–0.1.4` spam-filter
rejections to land four times in a row without anyone noticing (audit
finding R20). Failing loud means the next regression of this shape is
caught at the release run, not by a Windows user trying to
`require('wickra')`.
This commit does NOT push, tag, or trigger a release — the user
publishes the 0.1.5 tag themselves once the manual npm-republish
smoke test confirms `wickra-win32-x64-msvc@0.1.5` accepts publish on
the freshly-released name.
PSAR — the wiki page still claimed "Node streaming. Not exposed in the
Node binding." That was true for an early release but is no longer:
the Node binding has exposed `psar.update(high, low, close)` since the
B1 fix in todo-detailed.md, and the WASM binding now exposes the same
streaming surface (audit finding R3, this branch). The page lists all
three streaming + batch shapes and adds a paragraph on the new
`is_ready` convention (audit finding R6 — flips on the first non-None
SAR, not on the seed candle).
HistoricalVolatility — the "Non-positive prices" edge-case note still
described the old behaviour ("that return is treated as 0"). The new
behaviour skips the bad tick entirely (audit finding R13): the
indicator's state is left untouched, the previous valid value is
returned, and the next real tick re-anchors against the previous
*valid* price. Updated the note to describe the new behaviour and
explain why (silently treating bad ticks as "no movement" underreports
realised volatility).
The rolling-window VWAP indicator (`wickra_core::RollingVwap`) was only
available in the Rust crate, even though the README's Volume-family
table already advertised "VWAP (cumulative + rolling)" as a cross-
language feature. Users on Python, Node or in the browser had to fall
back to the cumulative `VWAP` or re-implement the rolling variant
themselves.
This commit closes the gap end-to-end:
- Python: `wickra.RollingVWAP(period)` — same constructor / `update` /
`batch` / `reset` / `is_ready` / `warmup_period` surface as `VWAP`,
plus a `period` property and a typed `__repr__`. The `__init__.py`
re-exports it and `__all__` lists it; the `.pyi` stub matches.
- Node: `RollingVWAP(period)` — napi class with the same lifecycle,
exported from `index.js` and declared in `index.d.ts`.
- WASM: `RollingVWAP(period)` — wasm-bindgen class with the same
`Float64Array` I/O as `VWAP`.
Tests added:
- Python: `test_rolling_vwap_streaming_matches_batch` — exercises
`update == batch` plus the full lifecycle on the shared OHLC fixture.
- Node: `RollingVWAP` row in the `candleScalar` parity table — covered
by the generic streaming-vs-batch + lifecycle harness.
- WASM: dedicated `wasm-bindgen-test` mirrors the Python test.
The wiki page `Indicator-Vwap.md` drops the "Rust-only" caveat and
gains Python / Node / WASM examples.
The README and Streaming-vs-Batch benchmark tables were a stale snapshot
("5 000-bar series", numbers from an older machine). Re-run
`python -m benchmarks.compare_libraries` on the current hardware against
the same peer set (finta + talipp; TA-Lib and pandas-ta stay excluded on
Windows) and replace the tables with the fresh numbers.
The new run uses the script's current defaults: a 20 000-bar batch series
and a 5 000-bar seed + 15 000-bar live streaming workload — both more
representative of real backtests than the previous 5 000 / 2 000-bar
sizes. Wickra still wins every batch row outright (3.5× to 1 244× faster
than the nearest peer) and the streaming RSI is ~13.8× faster than
talipp's incremental implementation.
Three content gaps in the wiki: there was no migration story for users
porting from TA-Lib, no strategy cookbook, and no FAQ. Add all three as
self-contained pages and link them from Home.md's "Wiki contents".
* docs/wiki/TA-Lib-Migration.md — full one-to-one mapping table from
every common talib.X(...) call to the equivalent Wickra expression,
plus a "what Wickra has that TA-Lib does not" / "what TA-Lib has that
Wickra does not (yet)" delta.
* docs/wiki/Cookbook.md — seven concrete strategy recipes (RSI mean
reversion, MACD histogram crossover, Bollinger breakout, ADX-gated
trend, multi-timeframe confirmation, SuperTrend trailing stop,
Chain<EMA, RSI>) with Rust or Python snippets.
* docs/wiki/FAQ.md — common questions on warmup, NaN handling, thread
safety, installation, performance and comparing Wickra to TA-Lib /
pandas-ta / talipp / finta.
Also extend the [Unreleased] CHANGELOG entry that records the
examples/<lang>/ restructure with the wiki additions; Home.md gains
three new bullets under "Wiki contents".
Finish the per-language `examples/<lang>/` restructure by relocating the
WASM browser demo from bindings/wasm/examples/ to examples/wasm/.
* `examples/wasm/index.html` is the moved file; its WASM module import
becomes `../../bindings/wasm/pkg/wickra_wasm.js` so the demo still loads
the wasm-pack output without copying it.
* bindings/wasm/README.md, Quickstart-WASM.md, examples/README.md and the
root README "Languages" + project-layout block all point at the new
path. The serve command in the docs now says "serve the repository root
and open examples/wasm/index.html".
`bindings/wasm/examples/` is empty after the move; the now-empty
directory is removed.
The three Rust examples (backtest, fetch_btcusdt, live_binance) used to
live each in their own crate's examples/ dir, splitting the example set
across crates and burying it inside the source tree. Move them into a new
workspace member crate at `examples/rust/` (package `wickra-examples`,
`publish = false`) so all language examples sit under one top-level
`examples/<lang>/` tree.
* `examples/rust/Cargo.toml` declares the per-binary deps (wickra,
wickra-data with the `live-binance` feature always on, serde_json, tokio
for the macro and current-thread runtime).
* `examples/rust/src/bin/{backtest,fetch_btcusdt,live_binance}.rs` are the
three migrated binaries; their doc-comments and the fetch_btcusdt output
path are updated for the new location and run command
(`cargo run -p wickra-examples --bin <name>`).
* Workspace `Cargo.toml` lists the new member; the now-empty
`[dev-dependencies]` extras (`wickra`, `tokio` in wickra-data and
`serde_json` in wickra) that existed only for these examples are dropped.
* The `[[example]] live_binance` table is removed from wickra-data's
manifest since the file moved out.
* README "Languages" + project-layout, examples/README.md, Quickstart-Rust
and Data-Layer are pointed at the new paths and commands.
`cargo build -p wickra-examples` and `cargo run --release -p wickra-examples
--bin backtest -- examples/data/btcusdt-1d.csv` both succeed; the rest of
the workspace (core, data, wickra) builds, clippies (`--all-targets -D
warnings`) and tests (508 core + 28 data + 1 integration + 74+3+1
doctests) all stay green.
The seven BTCUSDT OHLCV datasets used to live under
crates/wickra/examples/data/, which buried them inside a Rust crate even
though the Node backtest example and the upcoming Rust/Node/WASM example
restructure need to reach them too. Move them to the workspace-level
examples/data/ so every language's examples can resolve the same path.
The bench (crates/wickra/benches/indicators.rs), the example_data
integration test, fetch_btcusdt.rs and the Node backtest example all take
the new ../../examples/data/ path; Data-Layer.md, examples/README.md and
the CHANGELOG entry are updated to match. No data file content changes.
Timeframe gained new/millis/seconds/one_minute_ms; add minutes, hours and
days alongside them. Each builds on seconds (minutes(5) -> a 300-second
bucket), consistent with Timeframe::seconds, and guards the multiplication
with checked_mul so an oversized n yields Error::InvalidTimeframe instead
of an overflow panic. A non-positive n is rejected by Timeframe::new.
Each method carries a runnable doctest, and unit tests cover the known
bucket sizes, non-positive rejection and overflow rejection.
Add seven OHLCV datasets under crates/wickra/examples/data/, one per
timeframe (1m/5m/15m/1h/12h/1d/1month), holding real BTCUSDT spot klines
fetched from the Binance REST API. The new fetch_btcusdt example
regenerates them: it paginates the klines endpoint through the system
curl, parses with serde_json, validates every candle via Candle::new and
keeps only fully closed buckets.
The indicator benchmarks now run against the 1m dataset instead of a
synthetic series, and a new example_data integration test checks that
every file parses and carries evenly spaced, monotonic timestamps.
The monthly file is named btcusdt-1month.csv rather than btcusdt-1M.csv
so it does not collide with btcusdt-1m.csv on case-insensitive
filesystems (Windows, default macOS).
The original taxonomy was four classical families plus a statistics group,
with the F1-F12 expansion slotted in as sub-categories. This regroups the
whole 71-indicator catalogue into eight top-level families, each with at
least five members:
Moving Averages (12), Momentum Oscillators (13), Trend & Directional (9),
Price Oscillators (5), Volatility & Bands (12), Trailing Stops (5),
Volume (9), Price Statistics (7).
- Wiki: docs/wiki/indicators/ reorganised into eight family folders; all 71
indicator pages moved with `git mv`. Every internal cross-link is
normalised to `../<family>/Indicator-X.md`, each page's `Family` field is
set to its new family, and two pre-existing `../Indicator-Chaining.md`
links (should have been `../../`) are corrected. A link check confirms
every relative wiki link resolves.
- Indicators-Overview.md fully rewritten around the eight families;
Home.md indicator reference and the README family table follow suit.
- Warmup-Periods.md gains the eight F13 indicators; CHANGELOG records the
46-indicator expansion (25 -> 71) and the eight-family taxonomy.
- Tests: Node indicators.test.js and Python test_new_indicators.py cover
all eight new indicators (Node 91/91, Python 117/117 green).
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 508 core tests,
25 data tests and 74 doctests green.
Second half of the eight indicators that fill out the new family taxonomy.
- Rust core: true_range.rs (TrueRange — the raw single-bar volatility ATR
averages), chaikin_volatility.rs (ChaikinVolatility — rate of change of a
smoothed high-low spread), z_score.rs (ZScore — price normalised against
its rolling mean and standard deviation) and linreg_angle.rs (LinRegAngle
— the rolling regression slope as a degree angle). 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 (ZScore
and LinRegAngle ride the scalar macros where possible) 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 next in F13c.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 508 core tests,
25 data tests and 74 doctests green.
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.
Finalises the F1-F12 indicator expansion (25 -> 63 indicators).
- Python `wickra/__init__.py`: import and re-export all 63 indicators,
grouped by family, with a matching `__all__`. The package previously
exposed only the original 25 even though the compiled module and the
`.pyi` stubs already carried the rest.
- Docs: `Home.md` and `README.md` indicator counts and family tables
updated to 63; `Indicators-Overview.md` already restructured per family
in F10-F12; `Warmup-Periods.md` gains all 38 new indicators across the
single- and multi-output tables (and the stale two-arg `Psar::new`
example is corrected to three args); `CHANGELOG.md` `[Unreleased]` lists
every new indicator by family.
- Tests: `bindings/node/__tests__/indicators.test.js` covers all 63
indicators (streaming==batch plus four new reference-value checks),
80/80 green; new `bindings/python/tests/test_new_indicators.py` covers
the 38 additions (streaming==batch, shapes, reference values,
lifecycle), Python suite 105/105 green.
- `bindings/node/index.js` regenerated by `napi build`.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 454 core tests,
25 data tests, 66 doctests, 80 Node tests and 105 Python tests green;
`cargo check -p wickra-wasm --tests` green.

summed volume, bounded to [-1, +1]), chaikin_oscillator.rs (Chaikin
Oscillator — the MACD of the ADL, EMA(ADL, fast) - EMA(ADL, slow)),
force_index.rs (Elder's Force Index — EMA of price change scaled by
volume), ease_of_movement.rs (Arms' Ease of Movement — SMA of distance
travelled per unit of volume). Each with a full Indicator impl,
runnable doctest and reference / property / warmup / reset /
batch==streaming tests.

Indicators-Overview.md and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 402 core tests,
25 data tests and 57 doctests green.
Completes the F9 family (Cumulative volume) end to end:
- Rust core: adl.rs (Accumulation/Distribution Line — cumulative
range-weighted volume) and vpt.rs (Volume-Price Trend — cumulative
volume scaled by percentage price change). Each with a full Indicator
impl, runnable doctest and reference / cumulative-property / warmup /
reset / batch==streaming tests.
- Python: PyAdl / PyVolumePriceTrend PyO3 classes + module registration
+ .pyi stubs (no parameters, like OBV/VWAP).
- Node: explicit AdlNode and VolumePriceTrendNode; index.d.ts and
index.js updated.
- WASM: WasmAdl and WasmVolumePriceTrend.
- Wiki: Indicator-Adl.md and Indicator-VolumePriceTrend.md plus rows in
Indicators-Overview.md and entries in Home.md.
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 373 core tests,
25 data tests and 53 doctests green.
Completes the F7 family (Volatility) end to end:
- Rust core: natr.rs (ATR as a percentage of close), std_dev.rs
(rolling population standard deviation), ulcer_index.rs (RMS of
trailing-high drawdowns — downside-only risk), historical_volatility.rs
(annualised sample stddev of log returns). Each with a full Indicator
impl, runnable doctest and reference / constant-series / warmup /
reset / batch==streaming tests.
- Python: PyNatr / PyStdDev / PyUlcerIndex / PyHistoricalVolatility
PyO3 classes + module registration + .pyi stubs.
- Node: StdDevNode / UlcerIndexNode via the scalar macro, explicit
NatrNode and HistoricalVolatilityNode; index.d.ts and index.js updated.

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 /

25 data tests and 31 doctests green.
The wiki had quickstarts for Python, Rust, and Node but none for the
WebAssembly binding, and the wickra-data crate (CSV reader, tick
aggregator, resampler, Binance feed) was not documented anywhere.
- Quickstart-WASM.md: install via npm, building with wasm-pack, and
streaming/batch/multi-output usage in a browser or bundler.
- Data-Layer.md: the wickra-data crate — CandleReader, TickAggregator
(including the opt-in gap fill), Resampler/resample_all, and the
feature-gated Binance live feed.
- Home.md links both from the wiki contents list.
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.
Indicators-Overview.md only had a "Deep dive" column in the Trend
tables; the Momentum, Volatility and Volume tables left readers without
a path to the per-indicator pages.
Add a "Deep dive" column to all eight remaining tables, linking each of
the 18 rows to its indicators/<family>/Indicator-*.md page. RollingVwap
points at the RollingVwap section of Indicator-Vwap.md (added in E18).
All link targets verified to exist.
Indicators-Overview.md listed Trix in the Trend section's EMA-family
table, while the README and the docs folder layout
(indicators/momentum/Indicator-Trix.md) place it under Momentum.
Move the Trix row into the Momentum "Unbounded oscillators" table — it
emits a rate of change, not a price-scale trend line — and leave a note
in the Trend section pointing there. Momentum is now the single
canonical family across the README, the folder layout, and the
overview.
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.
