I could not find a way to get %B from stock fetcher (I may have over looked it) so here is a version that I have come up with that uses Bollingers preffered method of "Typical Price" rather than the usual close price:

Fetcher[
set{sumRange, high + low}
set{sumRange2, sumRange + close}
set{typicalPrice, sumRange2 / 3}

set{b1, typicalPrice - upper bollinger(20)}
set{b2, upper bollinger(20) - lower bollinger(20)}
set{prctB, b1 / b2}

prctB is above 0
AND add column trueVal
AND add column prctB
AND draw prctB
]



Does anyone know how to calculate multiple values in a single set method? I would like to do something like "set{TP, (close + high + low) / 3}"...

Did I miss the stock fetcher version of %B?

Here is a variation of %B that is recommended as a buy signal by Bollinger. I must admit it does yeild some very interesting results on the little bit of back testing I have done.

Fetcher[
set{sumRange, high + low}
set{sumRange2, sumRange + close}
set{typicalPrice, sumRange2 / 3}

set{b1, typicalPrice - upper bollinger(20)}
set{b2, upper bollinger(20) - lower bollinger(20)}
set{prctB, b1 / b2}

prctB is above 0.8
AND MFI(10) is above 80

AND add column trueVal
AND add column MFI(10)
AND add column prctB
AND draw prctB
]



Here is more information for Bollinger method II: http://www.bollingeronbollingerbands.com/methods/?method=2

Intro from web page:
Our second Bollinger Band demonstration method relies upon the idea that strong price action accompanied by strong indicator action is a good thing. It is a confirmation approach that waits for these two conditions to be met before giving an entry signal. Of course, the opposite, weakness confirmed by weak indicators, generates a sell signal.

Ooops! the astute reader will have noticed I messed up the %B calculation. Here is the correct form (I hope :)

Fetcher[
set{sumRange, high + low}
set{sumRange2, sumRange + close}
set{typicalPrice, sumRange2 / 3}
set{b1, typicalPrice - lower bollinger(20) }
set{b2, upper bollinger(20) - lower bollinger(20)}
set{prctB, b1 / b2} prctB is above 0.8
AND MFI(10) is above 80
AND add column trueVal
]




Although the previous filter does yeild some interesting short prospects.

darn still messed it up (I wish I could edit the original post). Having Copy & Paste problems :(

Fetcher[
set{sumRange, high + low}
set{sumRange2, sumRange + close}
set{typicalPrice, sumRange2 / 3}

set{b1, typicalPrice - lower bollinger(20)}
set{b2, upper bollinger(20) - lower bollinger(20)}
set{prctB, b1 / b2}

prctB is above 0.8
AND MFI(10) is above 80

AND add column trueVal
AND add column MFI(10)
AND add column prctB
AND draw prctB
