Bobby, Use: StartIndex = Max(BeginValue(BarIndex()), 0); EndIndex = Max(EndValue(BarIndex()), 0);
Double-click on the chart to choose your start bar (will highlight green) & do the same to pick your end bar (highlights red). You can then use something like: Difference = Close[StartIndex] - Close[EndIndex]; The MAX... when determining the index sets 0 for both indexes when you have no bars selected, otherwise you'll get an error trying to use the indexes.
