Trend indicator that plots below the price when bullish and above when bearish?

[theLEMband]

I'm looking for an indicator that I've seen in the past that is similar to the yellow lines on the picture below (ADX portion of the CSA study) . However, it plots at the bottom of the chart when bull trending and at the top when bear trending, which makes me think it may have been different than ADX.

I have been searching through the forums and looking through the universe of thinkscript, but haven't been able to find it. Does anyone remember a study like that?
Thanks,

declare lower;

input length = 10;
input overBought = -20;
input overSold = -80;

def hh = Highest(high, length);
def ll = Lowest(low, length);
def result = if hh == ll then -100 else (hh - close) / (hh - ll) * (-100);

plot WR = if result > 0 then 0 else result;
WR.SetDefaultColor(GetColor(1));

plot Over_Sold = overSold;
Over_Sold.SetDefaultColor(GetColor(8));

plot Over_Bought = overBought;
Over_Bought.SetDefaultColor(GetColor(8));

Hope this helps...
