I would like to suggest the addition of a Price Alert event schema to the Proactive Events catalog. That would be especially useful for anyone building informational/financial skills for stock market price alerts, for instance.
Now, since this type of schema does not yet exist, do you have any suggestion for what schema is best to use for a price alert? AMAZON.MessageAlert looks like it's the closest thing, but I still have some doubts on whether this might actually work. I'm going to do some testing, but I'm open to new ideas as well.
