This series explains how you can implement a pair trading system with Python. We will use jugaad-data for extracting data and pandas for analysis. This implementation is based on Zerodha’s varsity article. I will keep reffering back to the varsity article so I can’t stress enough how important it is to read that article is to understand the python implementation discussed here.
I’m summarizing the process in these easy steps, you can click on the each step to follow the code.
Varsity article on which this implementation is based, it discusses a lot of options but ultimately chooses just one for approach and even this implementation will follow the same approach, so please keep in mind that there are multiple ways to approach this problem. Once you understand the process, I encourage you to play with different steps and see the results.
Also if you find any mistakes in the implementation, do report them on the github issues page.
