Two unrelated newer-toolchain breakages bundled because they hit on the
same CI run and have the same shape (newer Rust got stricter about
patterns we used):
1. clippy 1.95 added the manual_midpoint lint which fires on every
instance of (a + b) / 2.0 with a help suggesting f64::midpoint.
CI runs with -D warnings so it became a hard error. Twelve sites
were affected — three real call sites in src/ohlcv.rs (median_price),
src/indicators/donchian.rs (DonchianOutput.middle),
src/indicators/ease_of_movement.rs (mid), and
src/indicators/super_trend.rs (hl2); plus eight test-helper
Candle::new constructions across accelerator_oscillator,
atr_trailing_stop, chaikin_volatility, chandelier_exit,
chande_kroll_stop, choppiness_index, super_trend, true_range.
All twelve switched to f64::midpoint (stable since Rust 1.85,
our workspace MSRV).
2. usize::is_multiple_of is still unstable (rust-lang/rust#128101) and
only stabilizes in Rust 1.87, but the MSRV CI job uses 1.85. The
two call sites in bollinger.rs and sma.rs (added with the R7
periodic-reseed tests) switched back to i % 2 == 0.
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.
