Works with:


  • The item's lowest price and price trend is displayed below its name, with extra information if the price is hovered.

    Item price displayed under name - Dota2

    Item price displayed under name - CSGO

    • Price trend shows the diference between the lowest price and the median price and it can be:
      • Ascending (↗) if the lowest price is bigger than the median price

        Price trend: Ascending (↗)

      • Stagnating (→) if the lowest price equals the median price

        Price trend: Stagnating (→)

      • Descending (↘) if the lowest price is lower than the median price

        Price trend: Descending (↘)

    • Price safety (the price's color) gets better with the more popular an item is (i.e. the more daily transactions the item has on the market) and it can be:
      • Green: over 50 daily transaction

        Price safety: Safe (Green)

      • Orange: less than 50 daily transactions

        Price safety: Warning (Orange)

      • Red: less than 10 daily transactions

        Price safety: Unsafe (Red)

  • "Not Marketable" is displayed for items that can not be sold on the Steam community market.

    Not Marketable items are also displayed

  • A 'Refresh' button is added to re-fetch the latest price for the item from the Steam market.

    Refresh price button available

  • A currency selector that allows you to choose the currency for which you want to see prices displayed...

    • ...from the list of currencies supported by the Steam Market

      List of available currencies

    • Your selected currency is remembered across page reloads

  • A popup with the selectable item's name is displayed if the item's name panel is clicked. This helps copy the item's name if needed.

Hope you like it ;)


Google Chrome: You will need to install this script using the Tampermonkey extension. This way the script should be able to run nicely and you will also benefit from automatic updates when new version are available.

Firefox: You will obviously need the Greasemonkey addon to be able to install and use this script. If you are using Firefox 30+ you need to make sure you use Greasemonkey version 2.2+ or the script won't work.


This script is initially inspired by the Steam Market Price Matcher script by the user tomatolicious.

A special shout out to people that helped out so far:

  • @joturako for suggesting a better and clever way of retrieving prices from the Steam Market
  • Enhanced Steam project for inspiration and reference on building a nice mapping of the available currencies on the Steam Market
  • for being awesome :)

  • Published on
  • Fixed minor bugs that managed to slip my sight during testing :)

Version 3.0! - Early Christmas present! :)

  • Addded the ability to select the currency you want to see prices displayed in
    • Offering a currency selector and remember the choice across page reloads
    • Refreshing all previously retrieved prices so they are now displayed in the new currency
  • Added a non-intrusive 'Donate' button at the end of the supported currencies list for generous people to find and use
  • Rewrote the way prices are retrieved and displayed:
    • Lowest price (default)
    • Median price (on price hover)
    • Price trend (default) can be:
      • Ascending (↗) if the lowest price is bigger than the median price
      • Stagnating (→) if the lowest price equals the median price
      • Descending (↘) if the lowest price is lower than the median price
    • Daily transactions (on price hover): Number of transactions that were made in the past 24 hours period
    • Price safety (the price's color)
      • Red: less than 10 daily transactions
      • Orange: less than 50 transactions
      • Green: over 50 transaction
    • This method should be much faster than the previous one because it uses a specialized JSON API instead of scraping the market listing page and extracting the value from there
  • Displaying an "Error" message instead of a missleading "Not Marketable" when the price can not be retrieved due to a network error or to Steam's servers going crazy

October 13, 2014

  • Updated the script to run with the recent changes done by the and websites.
  • Accepting donations through the published Steam Trade link in the "Donations" section above.
  • Removed the 'Show listings' custom button, since this feature is provided by the website by default through the new "Market" link.

Accepting donations! The script seems to have caught on. I am very happy with that and, if anyone is interested in donating, it is now possible. Thank you for your support!

Mar 17, 2014 is now supported!

  • Fixed the "Remove item" behavior when clicked that was causing the copy-item-name popup to also show.
  • Skipping the d2l generic items ("Any Common", "Any Rare", etc.) since they don't exist on the Steam Market and should not be handled by the script.

Mar 16, 2014

Version 2.0

  • Rewrote the way items are augmented with price information and extra buttons and, as a result:
    • The script now works for all views of the site, including backpack, profile, etc.
    • No more problems with the script not loading and having to refresh the page.
    • The script is more responsive, not having to wait for the page to fully load as before.
  • Added a refresh button for the price of an item, in case the user wants to get the latest price or if the item wrongly displays as Not Marketable and the user knows otherwise.
  • Added a button to open the Steam market listings in a new tab for an item, so that the user can quickly consult other price offers and price variations over time.
  • Fixed script not loading if the website is opened with "www"
