timestrader-preprocessing 1.0.3

Data preprocessing pipeline for TimeStrader AI trading system - Google Colab optimized

TimeStrader Preprocessing

A pip-installable package providing TimeStrader data processing capabilities optimized for Google Colab training and retraining workflows.

🚀 Quick Start

Installation

For Google Colab (Recommended)

pip install timestrader-preprocessing[colab]

Basic Installation

pip install timestrader-preprocessing

Production Environment

pip install timestrader-preprocessing[production]

Basic Usage

import timestrader_preprocessing as tsp

# Check environment
print(f"Running in Colab: {tsp.is_colab_environment()}")
print(f"Environment info: {tsp.ENVIRONMENT_INFO}")

# Load and process historical data
processor = tsp.HistoricalProcessor()
data = processor.load_from_csv("mnq_historical.csv")
indicators = processor.calculate_indicators(data)
normalized, params = processor.normalize_data(indicators)

print(f"Processed {len(data)} candles")
print(f"Data quality: {processor.get_quality_metrics()}")

📋 Features

Historical Data Processing

• OHLCV Data Loading: CSV and pandas DataFrame support
• Technical Indicators: VWAP, RSI, ATR, EMA9, EMA21, Stochastic
• Data Validation: Comprehensive outlier detection and quality scoring
• Normalization: Z-score normalization with rolling windows
• Parameter Export: Export normalization parameters for production consistency

Google Colab Optimization

• Fast Installation: < 2 minutes in Colab environment
• Quick Import: < 10 seconds package initialization
• CPU-Only Dependencies: No CUDA/GPU requirements for basic functionality
• Memory Efficient: < 100MB package overhead after import
• Environment Detection: Automatic Colab/Jupyter detection

Real-time Components (Production)

• Streaming Normalization: Real-time data processing with exported parameters
• Production Integration: Compatible with TimeStrader VPS deployment

📖 Detailed Documentation

Historical Processor API

from timestrader_preprocessing import HistoricalProcessor

# Initialize processor
processor = HistoricalProcessor(config_path="config.yaml")

# Load data (supports file paths, StringIO for Colab)
data = processor.load_from_csv(
    file_path="data.csv",
    progress_bar=True  # Show progress for large files
)

# Calculate technical indicators
indicators = processor.calculate_indicators(
    data=data,
    indicators=['vwap', 'rsi', 'atr', 'ema9', 'ema21', 'stoch']
)

# Normalize data with rolling window
normalized, params = processor.normalize_data(
    data=indicators,
    window_size=288,  # 24 hours for 5-min candles
    method='zscore'
)

# Export parameters for production
processor.export_normalization_parameters(
    params=params,
    output_path="normalization_params.json"
)

# Get data quality metrics
quality = processor.get_quality_metrics()
print(f"Quality score: {quality.score:.2%}")

Environment Detection

import timestrader_preprocessing as tsp

# Check environment
if tsp.is_colab_environment():
    print("Running in Google Colab")
    # Colab-specific optimizations
elif tsp.is_jupyter_environment():
    print("Running in Jupyter notebook")
else:
    print("Running in standard Python environment")

# Access environment information
info = tsp.ENVIRONMENT_INFO
print(f"Python version: {info['python_version']}")
print(f"Package version: {info['package_version']}")

Configuration Management

from timestrader_preprocessing.config import get_default_config

# Get default configuration for current environment
config = get_default_config()

# Colab-specific configuration
colab_config = get_default_config(environment='colab')

# Production configuration  
prod_config = get_default_config(environment='production')

🧪 Testing

# Run all tests
pytest

# Run specific test categories
pytest -m unit          # Fast unit tests
pytest -m integration   # Integration tests  
pytest -m colab        # Colab-specific tests
pytest -m package      # Package installation tests
