[amibroker] Re: Difference between any two selected line in intraday charts

["ian_rosbif" <ian_rosbif@xxxxxxxx>]

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. 

Cheers,
Ian
