How to Test Your Internet Connection Speed for Stock Trading

Helpful advice & tips for traders to ensure they’re maximizing the internet speed they’re paying for.

Test your internet speed for trading

You’re paying an ISP (internet service provider) for an internet connection rated at a certain speed. There are endless tests available to determine your connection speed. It’s important to know that you’re getting the speed you’re paying for.

You shouldn’t rely on one single test/tool or website to gauge your speed. It’s best to confirm with many different sources to get a really good idea of where you’re at. Also, testing at different times of the day and making sure you’re testing under the same circumstances is key. If you’re uploading a bunch of YouTube videos or streaming a movie it would alter the test results.

Use a Hard Wired Connection

Traders need all the advantages they can get. The speed of your computer (CPU, RAM, SSD) is important, as well as the rated speed of the ethernet ports on your motherboard.

This could be the best piece of advice you’ll ever get. For trading, always use a hard wired ethernet port for your internet connection, avoid WiFi if you can! We’ll go into further detail on this in future articles, but a hard-wired connection is always the preferred method of connecting your computer to your router.

Preparation for Testing Internet Speed

Before running any testing, make sure to do the following:

  • To start with, give your system a reboot.
  • Update Windows – run the Windows update tool and reboot the computer to apply the updates when prompted to. You don’t want Windows trying to download or install updates while testing your internet connection.
  • As mentioned earlier, use a hard-wired LAN connection. It’s ok to test with wireless later to get an idea of how fast your wireless connection is on various devices. But to get the best results for determining how fast your connection actually is through your ISP hard wired is the way to go.

Download Speed vs Upload Speed

In the simplest sense, download is receiving data to your computer and upload is sending data. The data transferred is measured in megabits. Typical downloading activities are watching YouTube videos, listening to music, browsing the web and watching movies on streaming services like Netflix.

Uploading is sending data from your computer to another device or server. Sending email, uploading videos to a YouTube account or sending your audio/video through skype or zoom requires uploading. It’s normal that your upload speed is significantly slower than download speed.

Google Internet Speed Test

Let’s start with the easiest test. Go to google and type in “speed test”. You should get a box at the top of your search results that looks similar to this:

Google internet speed test.

The test should finish up fairly quickly, usually under a minute. Then the results will pop up.

Your results will, of course, be much different than this. Your speed could be significantly faster or slower.

OOkla Speedtest

When testing internet speed, the first go-to site we think of is

OOkla Speedtest claims they have over ten million unique tests every day. They’ve been around since 2006 and have completed over 45 billion tests according to their website.

What’s nice about Speedtest has always been its simplicity. Just go to the site and click the big “Go” button and the test begins! Just be careful not to click any of the ads surrounding the “Go” button. We understand they need to make money, but it does make the site look a little unpolished with all the ad placements.

Below the “Go” button you can change the server. Usually, it’s ok just to leave the default server that’s set. We recommend running the test 2 to 3 times for each server you select so the results can be compared. measures your network connection in real-time so tests done at different times can vary based on network congestion and other factors. Also, testing over WiFi can provide mixed results that are impacted by the type of wireless router you own and the device you’re testing from. To get a real feel of what your internet connection is capable of, it’s best to test with a wired internet connection. You should have the newest appropriate hardware (wireless router, cable modem) that can take advantage of the advertised speed you’re paying for.

Multi vs Single Connection

You’ll see below the “Go” button another option – Multi & Single. By default, it should be set to Multi. “Multi” means that multiple connections are used for the test. The speed is measured across all of them to determine the results.

What can impact Speedtest results?

Servers used during testing can perform differently. Typically, servers closer to you will perform faster. That’s why testing with several different servers will give you a better picture of your speed. Also, different web browsers can product different results, we recommend using Google Chrome or Microsoft Edge.

Testing your internet connection couldn’t be simpler than going to The test begins automatically, you don’t need to even click a “Go” button like with OOkla. was developed by Netflix. Being the largest streaming service in the world, they have a vested interest in making sure their customers are informed about the speed of their connection.
