Price within % of Bollinger Band

BLUF: Scanner to find when close is within x% of Upper Bollinger Band
Looking for a scanning script to scan for when the close of a stock is within say 2% of the Upper Bollinger Band. Any help? Based off that script, I can then reverse it to find the same thing but with Lower Bollinger Bands. This strategy can help with trading with reversion to the mean sort of setups.
Thank you.

Thank you.

here is a lower test study, that i think should work for a scan.
it plots a value of 0 or 1, depending if close is near the upper bb line.

i copied the code from BollingerBands
replaced plots with def
added an input to select a desired percent

load this as a lower study and load BollingerBands in upper chart, and test it with different %'s.

declare lower;

input price = close;
input displace = 0;

input averageType = AverageType.Simple;

def sDev = stdev(data = price[-displace], length = length);

def MidLine = MovingAverage(averageType, data = price[-displace], length = length);
def LowerBand = MidLine + num_Dev_Dn * sDev;
def UpperBand = MidLine + num_Dev_Up * sDev;

#LowerBand.SetDefaultColor(GetColor(0));
#MidLine.SetDefaultColor(GetColor(1));
#UpperBand.SetDefaultColor(GetColor(5));


# positive above upper , negative below upper
def diffper = (100*(close - UpperBand)/UpperBand);
def nearupper = (absvalue(diffper) <= upper_line_near_percent);

plot zu = nearupper;

#-----------------------
input test1 = no;
addchartbubble(test1, 0.5, diffper, color.yellow, yes);

Thank you so much! This is exactly what I was looking for. I wish I had your skills. Thank you again.
