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.

Executing orders with the IB API

In Chapter 10, Set Up the Interactive Brokers Python API, we created contract and order objects. Using these, we can use the IB API to execute trades. But before we can execute trades, we have to understand the concept of the next order ID.

The next order ID (nextValidOrderId) is a unique identifier for each order. Since up to 32 instances of a trading app can run in parallel, this identifier makes sure individual orders are traceable within the trading system. nextValidOrderId is used to preserve order integrity and prevent overlap between multiple orders submitted simultaneously or in rapid succession. When our trading app connects to the IB API, it receives an integer variable called nextValidOrderId from the server that is unique to each client connection to TWS. This ID must be used for the first order submission. Subsequently, we are responsible for incrementing this identifier for each new order.
