Filtering in StockFinder is done using Rules, so you will have to make at least one in order to do so. One option would be to create the following RealCode Rule:

If 5 <= Price.Last AndAlso Price.Last <= 60 Then Pass

Another option would be to right-click on Price History and select Create Rule | Greater Than Value: 5, right-click on Price History and select Create Rule | Less Than Value: 60 and then Drag and Drop these Rules onto each other and select Create New Combo Rule.

Either the RealCode Rule or the Combo Rule can be Dragged and Dropped to the Filter to limit the Stocks listed for the Watchlist to those meeting your conditions.
