For this example I am looking at companies that have a market cap between $150,000 and $10,000,000 (in millions). Doing this gives us a list of stock tickers that we can then analyze one at a time.Ĭurrently, the library supports filtering stocks by their region, sector, market cap, and exchange. The library “ get-all-tickers“, allows us to filter through all of the stocks in the NYSE, NASDAQ, and AMEX.

If you are serious about automating your investing strategies, I would highly recommend checking out their extensive list of courses.įor a limited time, you can use our code HANDSOFF at checkout to get a 10% discount on any course(s)!

Their courses helped me a great deal when I was first learning how to algorithmically trade, even to this day I am still learning from their more advanced courses. Importing the necessary libraries can be done in two simple lines of code.Ī lot of what I know today is because of Quantra. Pull and save historical stock data from Yahoo Finance.Create and delete a file on our local machine (computer) to store the stock data.Filter through all of the stocks in the NYSE, NASDAQ, and AMEX.These libraries are going to help us make quick work of the data importing process. Programming is a skill best acquired by practice rather than from books. And don’t worry, everybody learns how to code through practice.
If this is your first time using Python (or coding in general), I’d recommend reading this article for a simple walk-through of the installation and startup process. Also, I’ve simplified the code by breaking it into sections and giving a description of what each part of the code does.
I figured that since this program is so integral for algorithmic investing, I need to break it down further and make sure that everyone understands how to use it!Īfter running this program you’ll be left with a folder on your device that contains the historical data of any number of stocks.
If you’ve read any of my articles about automating the stock analysis process, you’ve probably seen this code before. Maybe you don’t even know what Python is, and that’s okay! I’ve got you. I’ve created this guide for Python developers of all skill levels. Effortlessly obtain the historical data of over a thousand stocks.
