I agree, and it will add icing on the cake when Graham, and other guru's,
start posting their excellent explanations of AFL directly into the ONLINE
USER MANUAL that can be accessed directly from the user manual while you are
reading the user manual description of a function. I just brought up the
user manual, clicked on Sum() from the ALPHABETICAL listings of AFL
functions. I saw that it has been improved. Now, when I click on "See
Updated/Extended Version Online", I do see a listing of
References:
The SUM function is used in the following formulas in AFL on-line library:
a.. Against all odds
b.. AJDX system
c.. Alpha and Beta and R_Squared Indicator
d.. Auto-Optimization Framework
e.. Bollinger band normalization
f.. CandleStochastics
g.. Chaikin Money Flow
This new functionality is an excellent improvement. However, I still didn't
see the very excellent explanation of SUM() that Graham created. I Tried to
add it myself via the "Comment" box. It then directed me to the
Amibroker Website, but when I got there, I found nothing that looked liike
it would allow me to add a comment to the Updated/Extended Version Online
User manual. I also saw nothing in the member's area that looked like it
might work
FWIW, I posess a very low level computer use skills.
Meanwhile, I am still hoping that somehow, someway, the guru's will start
adding their descriptions to the Updated/Extended Version Online User
manual.
It will be a great day when this happens. Just imagine, all you would have
to do is open the user manual, read the software description, and as usual,
end up really puzzled. Not to worry though, because now you now just click
to go online, and a whole new world of wonderful plain english explanations
of your function will be right in front of you.
Anyway, once again, here is Graham's excellent explanation of the use of
Sum(). Ron D
This is Graham's explanation of Sum();
====================================================
Sum adds up the last "n" number of bars. It sums whatever you put into the
first part of the sum formula.
Cum(1) adds 1 to the previous value of Cum, so the first bar is 1 and it
just keeps adding one to the last bar value of cum(1). You can use Cum to
add anything, like how many times you get rising days in the entire chart
Rise = C>O; //this gives results of 0 or 1
TotalRise = Cum(Rise);
You could limit this as well to time periods, or any other condition
Example would be one for total rise days since 1995
RecentRise = C>O and Year()>=1995; //this gives results of 0 or 1
TotalRise = Cum(RecentRise);
If you wanted to know how many rising days in the last 12 bars you would use
LastRises = Sum(Rise,12);
Hope this helps
Cheers,
Graham
