Dynamic Zones

Re: TASC, July 1997, p.42, "Dynamic Zones" by Zamansky & Stendahl.

This article offers an idea for flexible buy/sell trigger levels for
oscillators, instead of fixed values.  It is based on the frequency of
occurrence of values within a look-back period.  The only code given was
for TradeStation.  Equis tell me that the calculations cannot be done in
MetaStock.

Would any mathematically literate person tell me how to implement it in
Excel?  It would be much appreciated.
