ATTACHED 2x .TXT-files + 4x .GIF-files.

With reference to George(Equis Support)'s excellent reply (att.)
and "working out" on your info as well, ( me+EqSup) have
managed to come to the BB's masterpiece(see .GIFs), ahumm!!.

I hope you will find them to 'wealthen' your use and that they're able
to give you the 'clear' pic you'ld expect them to return.

Please, can you keep me+List informed on your 'achieving' 
the BB and its extended accessories?

See the attached formula 'BBAcc' - file and the .gifs for results.

For best results, John Bollinger 'sticks' to '2' and '20' and
Jan van Gemeren to '1 + 1.5' ,
but here too, see the attachements for results and/or
like your "concocted one" keep distilling the brew.

B%B is a "square"(inner window) version of the Bollinger Bands.
B%B shows where the Price resides in the Band Width(range),
with the OB-OS levels 0 and 100  as horizontal lines:
Above 100 = Price is above the BB-Upper band/Overbought
Below    0   = Price is below the BB-Lower band/Oversold.
(Produces quite often early ob-os zone arrivals, start/end of a trend).

Williams%R I am not familiar with (enclosed on -3.gif for comparissing).
Note that all -x.gif's have the same "underlay/time-span".

A plot that shows % of the BB Width(range) is formula #116.
The same over 70-period is #117.
Note again that John Bollinger's time-span of 20 is the underlay.  
'Yours' over 70-period with time-span 70 is #123 + #124.

Another note, the 'Equis' Band Width formula #114 is the BB-Ratio.
Widening Bands = High Ratio
Narrowing Bands= Low Ratio.

I received Equis George's reply when finishing the #xxx formulas,
but managed to make them visable in the 'last' .gif-file.
