Graham,
Your examples and explanations are very good.
Maybe you should write an addendum to the User's Guide in your spare
time.

Subject: RE: [amibroker] Can someone
explain what this is doing?
Sum adds up the last "n" number of bars. It sums whatever
you put into thefirst part of the sum formula.Cum(1) adds 1 to the
previous value of Cum, so the first bar is 1 and itjust keeps adding one
to the last bar value of cum(1). You can use Cum toadd anything, like how
many times you get rising days in the entire chartRise = C>O; //this
gives results of 0 or 1TotalRise = Cum(Rise);You could limit this
as well to time periods, or any other conditionExample would bne for total
rise days since 1995RecentRise = C>O and Year()>=1995; //this gives
results of 0 or 1TotalRise = Cum(RecentRise);If you wanted to know
how many rising days in the last 12 bars you would useLastRises =
Sum(Rise,12);Hope this helpsCheers,Graham<A

returns the number of the last bar. But what is Sum doing and what
