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.

Building pandas Series and DataFrames

A Series is a one-dimensional labeled array that can hold any data type, including integers, floats, strings, and objects. The axis labels of a Series are collectively referred to as the index, which allows for easy data manipulation and access. A key feature of the pandas Series is its ability to handle missing data, represented as a NumPy nan (Not a Number).

Important

NumPy’s nan is a special floating-point value. It is commonly used as a marker for missing data in numerical datasets. The nan value being a float is useful because it can be used in numerical computations and included in arrays of numbers without changing their data type, which aids in maintaining consistent data types in numeric datasets. Unlike other values, nan doesn’t equal anything, which is why we need to use functions such as numpy.isnan() to check for nan.

Furthermore, the Series object provides a host of methods for operations such as statistical...
