You can (untested) probably use the ZoomToIndex() function.
The BI for the last bar is Lastvalue( barIndex())
If you want then blank bars you can make that
LastValue( ref(BarIndex(),-10);
If you want a zoomwidth of 50 bars then the BI for the first bar in
the Zoom range would be LastValue( ref(BarIndex(),-10-50);
To zoom all windows at the same time use a staticvar counter for
each chart. If the chart counter is less then the master zoom chart
counter execute the zoom function and increment it the counter.
gotta go...
