Hi! We didn’t see any tools for sending percentage based notifications on stock dips. So we decided to build our own app.
Basically we allow for easily tracking a large group of stocks eg. by index. Then setup percentage based notifications that applies for each stock in the watchlist.
A lot of other tools have price drop notifications per stock, but this requires constant attention and time to setup for eg. 100 stocks. As well as the hefty price tag that comes with most financial tools...
