Udo,

Markus said in his post among other things:
      " I want to buy when the high is higher than the highest high of
the last 25 days and sell and the low is lower then
       the last 10 days."

So, Isn't he actually saying that if Today's high is... greater than...
the Highest High value of the High from the Preceeding 25 days.....which
to me is:... Buy=High ( todays high ) > Ref(HHV(H,25),-1);....we are
looking for the Highest High from the preceeding 25 days...starting
yesterday....


Please explain to me how you read your formula.....
buy = HHV(high, 25) == high;


Thank you
Anthony
