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.

Calculating asset returns using pandas

Returns are integral to understanding the performance of a portfolio. There are two types: simple returns and compound (or log) returns.

Simple returns, which are calculated as the difference in price from one period to the next divided by the price at the beginning of the period, are beneficial in certain circumstances. They aggregate across assets, meaning the simple return of a portfolio is the aggregate of the returns of the individual assets, weighted according to their proportions. This trait makes simple returns practical for comparing assets and evaluating portfolio performance over short-term intervals.

Simple returns are defined as follows:

R t =  P t P t1 _ P t1  =  P t _ P t1  1

On the other hand, compound returns, which are calculated using the natural logarithm of the price-relative change, are additive over...
