average true range for 1 hour and 4 hour charts

Hello,

can any one make an indicator which can show ATR for 1 hour,4 hour or may be adjustable for different time frame, ATR as a _number_ on the corner(which shud be adjustable) of the screen instead of the typical indicator window type tt comes w MT4?

is this idea workable?

Try this indicator, might be what you are after.
