I’d like to customize the way posts are rendered on my hosted Discourse instance. For example, if I wanted to link stock symbols that start with a dollar sign (“cashtags”) like $AAPL, how would I do this?
You would need to write a plugin that would scan the post content for /\$(\w+)\b/ and replace it with a link to the corresponding stock.
Note: if you are hosted with us, we only allow custom plugin on the enterprise data plan.

Where would they link to?
Interesting…
Best would be just yahoo finance?
Perhaps finfiz.com or barchart.com?
I would love a plugin with this functionality.

Is there a way of adding a live price after a symbol has been typed? Possibly with conditional formatting for green or red depending on its movement.
ie
$APPL $148.70
It would be possible with a custom theme component using decorateCookedElement from the Discourse API. You’d have to make a request to a third-party service to get the stock information, and then pull that in.

Take a look at: Custom Mentionables - plugin - Discourse Meta as a starting point (you’d have to create the dataset though).
