This article will be a short one but it might help you out when going through the coins on coinmarketcap.

Nothing too fancy; just a simple userscript I have created to compare 24H volume to the current marketcap of a particular coin. The script is open-source and needs to be imported manually.

An extra column on the right is added with a VOLUME : MARKETCAP ratio indicator

The userscript

(scroll down for installation guide)

Chrome users can use Tampermonkey. Firefox users can use Greasemonkey.

Both extensions will give you the ability to manually add scripts which will be executed automatically on the targeted website.

Because scripts being executed on targeted websites poses a security risk I will explain the code in detail below. I didn’t put a lot of effort in this userscript but it works and that’s what matters.

The userscript can be found here:

The first part of the code consists of some variables required by the extension. Such as the name of the script, the author and so forth.

Underneath the webpages are declared where the code will be executed and no extra permissions are requested/granted.

The second part of the code will create a function, append a field to each row and perform the calculation necessary to display the percentage.

That’s all there’s to it. Yes. Really.

Installing the userscript

Once you have installed the extension, click on the icon and select ‘Dashboard’.

The next step is to create a new userscript and copy the code into it.

Click on the little [+] icon in the dashboard.

Delete everything in the text field and paste the code in.

Click on [File] -> [Save].

That’s all. You can now navigate to coinmarketcap.com and enjoy the extra indicator!

See you soon
