ARTICLE : 
RINA Systems is charging for $299 p.a. for this.

Code from Stocks & Commodities, July '97, p.47:
SellZone = DZSell(Par1,Par2,Par3,Par4,Par5,StartPrS,N);

Par1 = length for %R
Par2 = smoothing for %R

StartPrS = sell probability factor
N = number of bars to consider when creating the historical 
probability
distribution function for the indicator.

The description in the article makes the indicator sound fairly 
simple--
all except for the mysterious three "extra parameters" do? (Par3, 
Par4,
Par5)

Any users know what they do? Are they really worth $300 a year?
END OF ARTICLE

Best regards,
