timestrader-preprocessing 1.0.11

TimeStrader Preprocessing Package for Historical Data Processing and Normalization

TimeStrader Preprocessing Package

A comprehensive data preprocessing package optimized for TimesNet and PPO model training in financial trading systems. This package provides historical data processing, normalization, and technical indicator calculation for financial time series data.

Features

• Historical Data Processing: Efficient processing of financial time series data
• Advanced Normalization: Multiple normalization methods including z-score with customizable scalers
• Technical Indicators: Built-in technical analysis indicators
• Data Leakage Prevention: Proper train/validation/test splitting with scaler management
• Performance Optimized: Designed for high-frequency trading applications

Installation

pip install timestrader-preprocessing

Quick Start

import pandas as pd
from timestrader_preprocessing import HistoricalProcessor

# Initialize processor
processor = HistoricalProcessor()

# Process your financial data
data = pd.DataFrame({
    'open': [100, 101, 102, 103, 104],
    'high': [101, 102, 103, 104, 105],
    'low': [99, 100, 101, 102, 103],
    'close': [100.5, 101.5, 102.5, 103.5, 104.5],
    'volume': [1000, 1100, 1200, 1300, 1400]
})

# Normalize data with proper train/validation/test splitting
train_data, scaler = processor.normalize_data(train_data, return_scaler=True)
val_data = processor.normalize_data(val_data, scaler=scaler)
test_data = processor.normalize_data(test_data, scaler=scaler)

Advanced Usage

Data Leakage Prevention

The package provides robust data leakage prevention for machine learning pipelines:

from sklearn.preprocessing import StandardScaler
from timestrader_preprocessing import HistoricalProcessor

processor = HistoricalProcessor()

# Training phase - fit scaler on training data only
train_normalized, scaler = processor.normalize_data(
    training_data,
    return_scaler=True,
    method='zscore'
)

# Validation phase - use existing scaler
val_normalized = processor.normalize_data(
    validation_data,
    scaler=scaler
)

# Test phase - use existing scaler
test_normalized = processor.normalize_data(
    test_data,
    scaler=scaler
)

Technical Indicators

# Calculate technical indicators
processed_data = processor.calculate_technical_indicators(data)

# Available indicators include:
# - Moving Averages (SMA, EMA)
# - RSI (Relative Strength Index)
# - MACD (Moving Average Convergence Divergence)
# - Bollinger Bands
# - And many more...

Requirements

• Python 3.9+
• pandas>=2.0.0
• numpy>=1.26.0
