Bollinger band difference indicator...

Does anyone know of (or have the ability to program) an MT4 indicator that calculates the difference between the upper and lower Bolinger bands...

I would like to see the upper and lower boundries plotted ontop of each other in a separate indicator window (to more easily compare slopes) with the Bollinger Spread (difference between boundries) plotted on top of them...

[EDIT]
Actually what I'd like to see is a slope comparison between the boundries...
[/EDIT]

any ideas?

Thanks,

Aaron
