pytafast 0.2.1

Python wrapper for ta-lib using nanobind

pytafast

A high-performance Python wrapper for TA-Lib built with nanobind. Provides 150+ technical analysis functions with pandas/numpy support and async capabilities.

Features

• 🚀 High Performance — C++ bindings via nanobind with GIL release for true parallelism
• 📊 Full TA-Lib Coverage — 150+ indicators including overlaps, momentum, volatility, volume, statistics, cycle indicators, and 61 candlestick patterns
• 🐼 Pandas Native — Seamless support for both numpy.ndarray and pandas.Series (preserves index and name)
• ⚡ Async Support — All functions available as async via pytafast.aio
• 🔒 Memory Safe — Zero-copy data access with proper ownership management

Installation

pip install pytafast

Build from Source

git clone --recursive https://github.com/twn39/pytafast.git
cd pytafast
pip install -v -e .

Quick Start

import numpy as np
import pytafast

# Using numpy arrays
close = np.random.random(100) * 100

sma = pytafast.SMA(close, timeperiod=20)
rsi = pytafast.RSI(close, timeperiod=14)
upper, middle, lower = pytafast.BBANDS(close, timeperiod=20)
macd, signal, hist = pytafast.MACD(close)

# Using pandas Series
import pandas as pd

close = pd.Series(np.random.random(100) * 100, name="close")
sma = pytafast.SMA(close, timeperiod=20)  # Returns pd.Series with preserved index

# Async support
import pytafast.aio as aio

async def compute():
    sma = await aio.SMA(close, timeperiod=20)
    rsi = await aio.RSI(close, timeperiod=14)
