So there’s no point in running your scraper over the weekend. For example, if you’re scraping data from NYC’s stock exchange, it closes at 5 pm EST on Fridays and opens on Monday at 9:30 am. You need to remember that the stock market isn’t always open. Wrapping Up: considerations when running your stock market data scraper And because it’s a list, we can now easily navigate it and pick those we need.Ĭompany = soup.find('h1', ).find_all('span').text Then we can use find_all(‘span’) to make a list of all the elements containing the span tag – which we know our target data uses. What we’ll do in this scenario is go up in the hierarchy and find a parent div we can exploit. Because Beautiful Soup returns a parsed tree, we can now navigate the tree and pick the element we want, even though we don’t have the exact CSS class. The good news is that we have a little trick to get it out. What’s more, depending on whether the change is positive or negative, the class of the element changes, so even if we select each span by using their class attribute, there will still be instances when it won’t work. However, the price, price change, and percentage change are separated into different spans. We just need to target the H1 tag with class ‘ text-2xl font-semibold instrument-header_title_GTWDv mobile:mb-2 ’. Now let’s inspect the HTML of the site to identify the attributes we can use to select the elements.Įxtracting the company’s name and the stock symbol will be a breeze. Note: Checking for JavaScript is important because Requests can’t execute JavaScript or interact with the website, so if the information is behind a script, we would have to use other tools to extract it, like Selenium. We didn’t find any additional JavaScript we’re good to go. Next we’ll do the W same for the rest of the information. It looks like there isn’t any JavaScript that could potentially interfere with our scraper. There are several ways to verify if some script is injecting a piece of data, but the easiest way is to right-click, View Page Source. Are these attributes consistent throughout all pages?.What attribute can we use to select the elements?.Is the data being injected with JavaScript?.At this point, we have three questions to answer: Inspect the Website’s HTML Structure ()īefore we start scraping, let’s open in our browser to get more familiar with the website.Īs you can see in the screenshot above, the page displays the company’s name, stock symbol, price, and price change.

You can use any parser you want, but we’re going with html.parser because it’s the one we like. Soup = BeautifulSoup(page.text, 'html.parser')

Next, we’ll open a new terminal and install our two main dependencies for this project:Īfter that, we’ll create a new file named “stockData-scraper.py” and import our dependencies to it. To begin, we’ll create a folder named “scraper-stock-project”, and open it from VScode (you can use any text editor you’d like).

With that out of the way, let’s jump into the code so you can learn how to scrape stock market data. It’s packed with tips and tricks, and goes over the basics you need to know to scrape almost anything. If you’re totally new to this library, check out our beautiful soup tutorial for beginners. Note: The script will work to scrape stock market data even without ScraperAPI, but will be crucial for scaling your project later.Īlthough we’ll be walking you through every step of the process, having some knowledge of the Beautiful Soup library beforehand is helpful. We’ll also show you how to protect your bot from being blocked by anti-scraping mechanisms and techniques using ScraperAPI.

Building a Stock Market Scraper With Requests and Beautiful Soupįor this exercise, we’ll be scraping to extract up-to-date stock prices from Microsoft, Coca-Cola, and Nike, and storing it in a CSV file.

In this tutorial, we’ll build a script to track multiple stock prices, organize them into an easy-to-read CSV file that will update itself with the push of a button, and collect hundreds of data points in a few seconds. Whether you’re an investor tracking your portfolio, or an investment firm looking for a way to stay up-to-date more efficiently, creating a script to scrape stock market data can save you both time and energy.
