Overview of this book

Discover how Python has made algorithmic trading accessible to non-professionals with unparalleled expertise and practical insights from Jason Strimpel, founder of PyQuant News and a seasoned professional with global experience in trading and risk management. This book guides you through from the basics of quantitative finance and data acquisition to advanced stages of backtesting and live trading. Detailed recipes will help you leverage the cutting-edge OpenBB SDK to gather freely available data for stocks, options, and futures, and build your own research environment using lightning-fast storage techniques like SQLite, HDF5, and ArcticDB. This book shows you how to use SciPy and statsmodels to identify alpha factors and hedge risk, and construct momentum and mean-reversion factors. You’ll optimize strategy parameters with walk-forward optimization using VectorBT and construct a production-ready backtest using Zipline Reloaded. Implementing all that you’ve learned, you’ll set up and deploy your algorithmic trading strategies in a live trading environment using the Interactive Brokers API, allowing you to stream tick-level data, submit orders, and retrieve portfolio details. By the end of this algorithmic trading book, you'll not only have grasped the essential concepts but also the practical skills needed to implement and execute sophisticated trading strategies using Python.

Measuring the volatility of a return series

Volatility plays an integral role in finance, serving as a key indicator of risk linked to a particular asset. A higher degree of volatility suggests a greater risk associated with the asset as it indicates more significant price changes and, therefore, a less predictable investment outcome.

Standard deviation is widely used as the measure of asset return volatility. It statistically quantifies the dispersion of asset returns from their mean, thus providing an effective metric for risk. When asset returns exhibit a larger standard deviation, it signifies more pronounced volatility, pointing to a higher risk level. Conversely, a lower standard deviation implies that the asset returns are more stable and less likely to deviate significantly from their average, indicating a lower risk.

The standard deviation’s value as a risk measure extends beyond its ability to quantify risk alone. It is a common component in calculating risk...
