Python Algorithmic Trading Cookbook

By: Pushpak Dagade

Overview of this book

If you want to find out how you can build a solid foundation in algorithmic trading using Python, this cookbook is here to help. Starting by setting up the Python environment for trading and connectivity with brokers, you’ll then learn the important aspects of financial markets. As you progress, you’ll learn to fetch financial instruments, query and calculate various types of candles and historical data, and finally, compute and plot technical indicators. Next, you’ll learn how to place various types of orders, such as regular, bracket, and cover orders, and understand their state transitions. Later chapters will cover backtesting, paper trading, and finally real trading for the algorithmic strategies that you've created. You’ll even understand how to automate trading and find the right strategy for making effective decisions that would otherwise be impossible for human traders. By the end of this book, you’ll be able to use Python libraries to conduct key tasks in the algorithmic trading ecosystem. Note: For demonstration, we're using Zerodha, an Indian Stock Market broker. If you're not an Indian resident, you won't be able to use Zerodha and therefore will not be able to test the examples directly. However, you can take inspiration from the book and apply the concepts across your preferred stock market broker of choice.

The recorded highest price of the day of a financial instrument

Often, trading strategies use the current day's highest price of a financial instrument as one of the qualifying conditions before making decisions to place new trades. This data is dynamic in nature as it may change continuously during the live trading hours. This recipe shows how to fetch the current day's highest recorded price of a financial instrument.

Getting ready

Make sure the broker_connection and instrument1 objects are available in your Python namespace. Refer to the Technical requirements section of this chapter to set up broker_connection. Refer to the Attributes of a financial instrument recipe of this chapter to set up instrument1.

How to do it…

Fetch and print the recorded highest price of the day of instrument1:

>>> high_price_day = broker_connection.get_high_price_day(instrument1)
>>> print(f'Highest price today: {high_price_day}')

We get the following output....
