In the following sequence
day(-1):99
day(0) :100
day(1) :95 [above 90]
day(2) :91 [above 90]
day(3) :89 [below 90]
day(0) is the peak(H,10) and it is recognized as a peak after day(3)
Note that a peak may be recognized after MANY bars, the stock may
stay for weeks in the [100,90] range. The first happy day it will
fall BELOW 90, then the peak(H,10) function will name day(0) as a
peak.
It is not far from the common sense, if you are is sales and if you
want the best day of the month, you will know it by the end of the
month. If the Feb13 is your top day, you never know it on Feb13.

10% lower than the most recent high. Most likely, this latest bar
will not be a new peak high level of the high, so I am wondering why
it is referred to as a new peak.

Thanks again for the explanation. Ron D

me check it out. I ran the example in the user manual and I had
the timespan set FROM 1/27/1995 and TO 1/27/2004. When I clicked on
SHOW CURRENT , there was a buy arrow at 2/1/2000 and the close price
was $71.00. This compares to the close price of $33.91 on 1/27/04.
I am unable to understand what CHANGE means in Peak(array,CHANGE,1).
