* test(rsi): cover period/value accessors, name, naive flat-series branch
Codecov flagged 7 lines in indicators/rsi.rs (file at 96.42%): const
accessors period (60-62), value (65-67), Indicator-impl name (145-147),
and line 167 in the test-helper rsi_naive's ag==0 fallback. The
proptest reference never lands on a fully flat series so the helper's
50.0 branch was dead.
Add accessors_and_metadata covering period/value/name and
naive_helper_flat_series_yields_50 driving rsi_naive on [42.0; 20] —
both avg_gain and avg_loss converge to 0, hitting the 50.0 branch.
rsi.rs now at 196/196.
* test(accelerator_oscillator): cover params accessor + name metadata
Codecov flagged 6 lines in indicators/accelerator_oscillator.rs (file
at 93.68%): const accessor params (69-71) and Indicator-impl name
(99-101). ac.rs now at 95/95.
* test(aroon): cover period accessor + name metadata
Codecov flagged 6 lines in indicators/aroon.rs (file at 94.28%): const
accessor period (56-58) and Indicator-impl name (104-106). aroon.rs
now at 105/105.
* test(atr_trailing_stop): cover params accessor + name metadata
Codecov flagged 6 lines in indicators/atr_trailing_stop.rs (file at
95.91%): const accessor params (77-79) and Indicator-impl name
(130-132). atr_trailing_stop.rs now at 147/147.
* test(chaikin_oscillator): cover periods accessor + name metadata
Codecov flagged 6 lines in indicators/chaikin_oscillator.rs (file at
95.27%): const accessor periods (76-78) and Indicator-impl name
(109-111). chaikin_oscillator.rs now at 127/127.
Only two doctests existed in wickra-core; none of the 25 indicator
types carried a runnable rustdoc example.
Add an "# Example" doctest to every public indicator type (all 26,
including RollingVwap): construct the indicator and stream 80 inputs
through update, asserting a value is produced. The candle-input
indicators build valid OHLCV candles inline. cargo test --doc
-p wickra-core now runs 28 doctests, all passing; fmt and clippy clean.
Adds the reset tests the audit named as missing (aroon, awesome
oscillator, donchian, keltner, williams_r, and both VWAP variants),
non-finite-input tests for every scalar indicator that guards is_finite
(WMA, RSI, MACD, Bollinger, KAMA), and naive-reference proptests for EMA,
RSI and ATR. 189 core tests pass.
A multi-language technical analysis library: 25 indicators across trend,
momentum, volatility, and volume families, every one a state machine with
O(1) per-tick updates. Batch evaluation is provided by a blanket extension
trait over the streaming primitive, so live trading bots and historical
backtests run the same code path.
What ships in this initial drop:
crates/wickra-core - 25 indicators, Indicator/BatchExt/Chain traits,
OHLCV types with validation; 171 unit tests,
property tests, Wilder/Bollinger textbook tests.
crates/wickra - top-level facade + criterion benches for every
indicator at 1K/10K/100K series sizes.
crates/wickra-data - streaming CSV reader, tick-to-candle aggregator,
multi-timeframe resampler, Binance Spot kline
WebSocket adapter behind feature live-binance;
11 unit + 1 doctest.
bindings/python - PyO3 + maturin, NumPy I/O, type stubs (.pyi),
56 pytest tests including streaming==batch
equivalence, Wilder reference values, lifecycle.
bindings/node - napi-rs native module, TypeScript .d.ts
auto-generated, 7 node --test cases.
bindings/wasm - wasm-bindgen ES module for browser/bundler/Node;
interactive HTML demo at examples/index.html.
examples/ - Python and Rust scripts: backtest, live trading,
parallel multi-asset, multi-timeframe, Binance.
benchmarks/ - cross-library comparison against TA-Lib,
pandas-ta, finta, talipp; Wickra wins every
category by 11-1030x (batch) and 17x+ streaming.
.github/workflows/ - CI matrix (Rust + Python + Node + WASM on
Linux/macOS/Windows), release pipeline for
PyPI wheels and npm.
