* feat: add hikkake-modified, homing-pigeon and neck-line candlestick patterns Five patterns, all `Input = Candle`, `Output = f64`: - Modified Hikkake (CDLHIKKAKEMOD) — a close-confirmed Hikkake: an inside bar then a breakout that closes back inside the inside-bar range; bullish +1, bearish -1. - Homing Pigeon (CDLHOMINGPIGEON) — two black candles, the second a small body inside the first, a bullish reversal; +1. - On-Neck (CDLONNECK) — long black bar then a white bar closing at its low (the neckline), a bearish continuation; -1. - In-Neck (CDLINNECK) — long black bar then a white bar closing just into its body, a bearish continuation; -1. - Thrusting (CDLTHRUSTING) — long black bar then a white bar closing well into but below the midpoint of its body, a bearish continuation; -1. Counter 264 -> 269 (mod-count == lib counted block; FAMILIES total 259 -> 264). * chore: sync indicator count to 269 --------- Co-authored-by: wickra-bot <wickra-bot@users.noreply.github.com>
Wickra — Python
Streaming-first technical indicators for Python. pip install wickra — no
system dependencies, no C build tooling.
Wickra is a multi-language technical-analysis library with a Rust core and bindings for Python, Node.js, and WebAssembly. Every indicator is an O(1) streaming state machine, so live trading bots and historical backtests share the exact same implementation. This package is the Python binding (PyO3); it exposes 200+ streaming-first indicators across sixteen families.
Install
pip install wickra
Pre-built wheels ship for Linux, macOS, and Windows — there is nothing to compile and no C library to track down.
Quick start
import numpy as np
import wickra as ta
# Batch: classic TA-Lib-style usage over a whole array.
prices = np.linspace(100, 200, 1000)
rsi = ta.RSI(14)
values = rsi.batch(prices) # numpy array, NaN during warmup
# Streaming: the same indicator, fed tick by tick in O(1).
rsi = ta.RSI(14)
for price in live_feed:
value = rsi.update(price) # no recomputation over history
if value is not None and value > 70:
print("overbought")
batch(prices) and feeding the same prices through update() produce
identical values — the equivalence is enforced by the test suite.
Documentation
The full indicator catalogue, guides, quickstarts, and API reference live in the main repository and documentation site:
- Repository & full indicator list: https://github.com/wickra-lib/wickra
- Docs (quickstarts, cookbook, TA-Lib migration): https://docs.wickra.org
- Runnable examples:

Wickra ships four bindings — Python, Node.js, WebAssembly, and Rust — that all
expose the same indicators from the shared, unsafe-forbidden Rust core.
Disclaimer
Wickra is an indicator toolkit, not a trading system. The values it computes are deterministic transforms of the input data — they are not financial advice and do not predict the market. Any use in a live trading context is at your own risk. The library is provided as is, without warranty of any kind.
