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.

## [Unreleased]
|
|
|
|
### Added
|
|
- 38 new technical indicators, taking the library from 25 to 63. Each is
|
|
implemented once in the Rust core and wired through the Python, Node and
|
|
WASM bindings, with reference-value tests and a dedicated wiki page:
|
|
- Trend: `Smma`, `Trima`, `Zlema`, `T3`, `Vwma`.
|
|
- Momentum: `Mom`, `Cmo`, `Tsi`, `Pmo`, `StochRsi`, `UltimateOscillator`,
|
|
`Ppo`, `Dpo`, `Coppock`, `AroonOscillator`, `Vortex`, `MassIndex`.
|
|
- Volatility: `Natr`, `StdDev`, `UlcerIndex`, `HistoricalVolatility`,
|
|
`BollingerBandwidth`, `PercentB`, `SuperTrend`, `ChandelierExit`,
|
|
`ChandeKrollStop`, `AtrTrailingStop`.
|
|
- Volume: `Adl`, `VolumePriceTrend`, `ChaikinMoneyFlow`,
|
|
`ChaikinOscillator`, `ForceIndex`, `EaseOfMovement`.
|
|
- Statistics: `TypicalPrice`, `MedianPrice`, `WeightedClose`,
|
|
`LinearRegression`, `LinRegSlope`.
|
|
- `TickAggregator::with_gap_fill` — opt-in mode that emits a flat placeholder
|
|
candle for every empty bucket between two ticks, keeping the candle series
|
|
evenly spaced for downstream indicators.
|
|
- CSV reader: a leading UTF-8 byte-order mark is stripped, fields are trimmed,
|
|
and the header is validated against the required OHLCV columns.
|
|
- CI: an `msrv` job that builds and tests the workspace on Rust 1.75 and the
|
|
node binding on Rust 1.77.
|
|
- Community health files: `CONTRIBUTING.md`, `SECURITY.md`,
|
|
`CODE_OF_CONDUCT.md`, issue / pull-request templates, `CODEOWNERS`, and a
|
|
Dependabot configuration.
|
|
|
|
### Changed
|
|
- `TickAggregator::push` returns `Result<Vec<Candle>>` (was
|
|
`Result<Option<Candle>>`) so a single tick can yield a closed bar plus gap
|
|
fillers.
|
|
- `Resampler::push` returns `Result<Option<Candle>>`: a candle in a bucket
|
|
earlier than the open bar is now rejected as out of order.
|
|
- Aggregated candles are finalised through the validating `Candle::new`, so a
|
|
volume that overflows to a non-finite value is surfaced as an error instead
|
|
of producing a poisoned candle.
|
|
- All GitHub Actions are pinned to commit SHAs; the four publish jobs run in a
|
|
protected `release` environment.
|
|
|
|
### Fixed
|
|
- `Timeframe::floor` no longer overflows for timestamps near `i64::MIN`.
|
|
- The aggregator rejects same-bucket ticks that arrive out of order instead of
|
|
silently overwriting the bar's close with a stale price.
|
|
- The Binance live stream reconnects with exponential backoff, skips non-kline
|
|
frames, applies a read timeout and message-size limits, and tracks a closed
|
|
flag.
|
|
- Example scripts: `live_trading.py` skips non-kline frames and validates the
|
|
symbol/interval; `backtest.py` and `multi_timeframe.py` report clear errors
|
|
for malformed CSV input.

|
## [0.1.4] - 2026-05-21
|
|
|
|
### Added
|
|
- GitHub Release runs now attach every built artefact (wheels, sdist, native
|
|
Node binaries, npm-pack tarballs, cargo `.crate` files) to the tag's
|
|
release page.
|
|
|
|
## [0.1.3] - 2026-05-21
|
|
|
|
### Fixed
|
|
- npm package ships the napi-generated loader and is built with `--platform`
|
|
so the per-platform binary is resolved correctly.
|
|
|
|
## [0.1.2] - 2026-05-21
|
|
|
|
### Fixed
|
|
- Release pipeline: per-platform idempotent npm publishing with a spam-filter
|
|
retry, and committed `npm/<platform>/` package templates.
|
|
|
|
## [0.1.1] - 2026-05-21
|
|
|
|
### Fixed
|
|
- Node publish step and coordinated version bump across all bindings.
|
|
|
|
## [0.1.0] - 2026-05-21
|
|
|
|
### Added
|
|
- Initial release: a streaming-first technical-analysis library with 25
|
|
indicators (SMA, EMA, WMA, DEMA, TEMA, HMA, KAMA, RSI, MACD, ROC, Stochastic,
|
|
CCI, Williams %R, ADX, MFI, TRIX, Aroon, Awesome Oscillator, Bollinger Bands,
|
|
ATR, Keltner Channels, Donchian Channels, Parabolic SAR, OBV, VWAP).
|
|
- Rust core (`wickra-core`), umbrella crate (`wickra`), and a data layer
|
|
(`wickra-data`) with a CSV reader, tick aggregator, resampler, and an
|
|
optional Binance live feed.
|
|
- Bindings for Python, Node.js, and WebAssembly.
