This one is pretty simple so I’ll just post the full code. I’ve taken the source code from the built in study and append a few lines that will run your scan. If you need further explanation just post a comment below this answer. Don’t forget to up-vote any answers that best solve your question.

input length = 10;
input value = -20;
def hh = Highest(high, length);
def ll = Lowest(low, length);
def result = if hh == ll then -100 else (hh - close) / (hh - ll) * (-100);
def WR = if result > 0 then 0 else result;
#first scan is for finding a cross back above over sold condition
plot scan = WR[1] < -80 and WR > -80;
#secon scan is for finding a cross back below over bought condition
#plot scan = WR[1] > -20 and WR < -20;

Good morning Pete. First thanks for responding so quickly.  Okay I really like the code that you sent. I can use it, but I was looking for sort of the opposite.  I wanted to scan for a cross above the over bought condition (greater than -20) and a scan below  the over sold condition ( less than -80).  I apologize for not being clear about my request.

Also, while using the code you posted I only got results for the cross going back above the over sold conditions.  I pasted the code in the scanner custom filter, but I’m wondering did I forget a step.  Do I need to take an additional step to trigger over bought scans?  Thanks in advance Fuzzy

Okay I’ll check out the videos.  Thanks again.
