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.

Converting a datetime object to a string

This recipe demonstrates the conversion of the datetime objects into strings which finds application in printing and logging. Also, this is helpful while sending timestamps as JSON data over web APIs.

How to do it…

Execute the following steps for this recipe:

  1. Import the necessary modules from the Python standard library:
>>> from datetime import datetime
  1. Fetch the current timestamp along with time zone information. Assign it to now and print it:
>>> now =
  1. Cast now to a string and print it::
>>> print(str(now))

We get the following output. Your output may differ:

2020-08-12 20:55:48.366130+05:30
  1. Convert now to a string with a specific date-time format using strftime() and print it:
>>> print(now.strftime("%d-%m-%Y %H:%M:%S %Z"))

We get the following output. Your output may differ:

12-08-2020 20:55:48 +0530

How it works...

In step 1, you import the datetime class...
