PythonPine v2.0 - High-Performance Technical Indicators

Vectorized Pine Script indicators for machine learning and algorithmic trading. 10-100x faster than loop-based implementations.

Features

• ⚡ NumPy/Pandas Vectorization - Millions of bars in seconds
• 🧠 ML Alpha Module - Z-score, percentile rank, fractional differentiation
• 📊 50+ Indicators - RSI, MACD, ATR, Bollinger, SuperTrend, Ichimoku...
• 🔄 Pine Script Parity - Same signatures, same math
• 📈 Price Action - Vectorized pattern detection

Installation

pip install pythonpine

Quick Start

import numpy as np
from pythonpine import rsi, macd, atr, zscore

# Your price data
close = np.random.randn(10000).cumsum() + 100
high = close + np.abs(np.random.randn(10000)) * 0.5
low = close - np.abs(np.random.randn(10000)) * 0.5

# Calculate indicators (returns NumPy arrays)
rsi_values = rsi(close, 14)
macd_line, signal, hist = macd(close)
atr_values = atr(high, low, close, 14)

# ML preprocessing
rsi_zscore = zscore(rsi_values, 20)  # Normalized for ML

ML Alpha Module

from pythonpine import zscore, percentile_rank, log_returns, fractional_diff

# Stationarity transforms
returns = log_returns(close)
frac_diff = fractional_diff(close, d=0.4)  # López de Prado method

# Feature engineering
rsi_z = zscore(rsi(close), 50)  # Z-score normalized RSI
rsi_rank = percentile_rank(rsi(close), 100)  # Percentile rank
