im looking toi write a scan for trending stocks or an indicator that is rising

tks in advance  marty

Bruce, I mis understood your answer.  I can do a smaller period.  The 76 is where I want the ranking to start.   I can use 50 or any time frame. If 50 doesn't work. Try 40

thanks again. Marty

Bruce, I asked tech support and they said i should ask a trainer

i'm trying to get this to work. it can either plot as an indicator or i can rank  any ideas where my error is  tks in advance   marty

input price = close; 
input length = 76; 
input RiskFreeReturn = 4; 
 
def ROC = if price[length] != 0 then (price / price[length] - 1) * 100 
else 0; 
 
def Ri = 100*(price - Highest(price,length))/Highest(price,length); 
 
def UlcerX = sqrt(average( (Ri*Ri), length)); 
 
# plot RiskFree = RiskFreeReturn; 
 
plot UPI = round((ROC - RiskFreeReturn)/sqrt(average( (Ri*Ri), length)),1);
