If you’re a regular on Twitter, you may have seen cashtags come up while scrolling through your feed. And that’s because the service uses them to track a tweet’s price. But that price isn’t limited by the value of the actual asset; it can be whatever the company says it is. And because companies are starting to use these things more frequently, it’s also making it easier to spot when a company’s price is up or down.

The extension provides price info for all cashtags. This means you’ll never have to memorize ticker symbols, you’ll just see the company name. Simply open the extension and then tap on any cashtag to see a complete list of prices for the last five days, along with how they’ve changed.
