I am looking for a web application, that can compare financial market values for specific stocks and email alert if they change within some defined range (ie. lower than specific value given for one piece of stock).
I can imagine such application running locally, however for usage across more devices the web service is more usable. As a result I would like to use something similar to Huginn as described in this topic but I would like to subscribe to a web service, that can host this solution. I would appreciate a free solution, though it is not a condition. My condition is to be tweaked for stock-oriented problematics.
