Hi Anthony,
Sorry for the delay in responding - I got caught up
in the new beta. It appears that you are trying to find the combos that fit
between your upper and lower limits? If that is the case, I think I see 2
problems:
1. I don't think you can do this by
selecting n=10. The code will execute start to finish for each of the 10
days, yeilding the same results for each day in your case. I think you could do
it by putting your Addcolumns inside a loop (if you really like
scrolling 8 - ) but it would probably be better to use the
interpretation window - I have used it in the past to create tables of
statistics and it worked pretty good.
2. Either way, code would need to be modified
- I might be able to work with you a bit in my spare time
- let me know if you are interested in pursuing it.
Steve

combinations
Steve,
Thanks for taking a look...
The output should look like this:
combination 1........
1...2...22...34...35...36
combination
2.........1...2...23...33...35...36
combination
3.........1...2...24...32...35...36
combination
4.........1...2...24...33...34...36
combination
5.........1...2...25...31...35...36
combination
6.........1...2...25...32...34...36
combination
7.........1...2...25...33...34...35
combination
8.........1...2...26...30...35...36
combination
9.........1...2...26...31...34...36
etc......
the looping is controlled / referencing the size
parameter....each of the combinations are controlled by the upper and lower
limits...in this case I set the upper and lower limit to 130...so each
combination will add up to 130...

Hi again Anthony,
I got interested in your code so I popped it
into AB. I haven't figured out what you are trying to do, but I tweaked
the syntax to make it like I *think* you intended it. I don't
think it will give the results you are expecting though - since you don't
reference any type of data, it just behaves the same for each of the 10
days. Could you provide a little more detail?
Steve
upperlimit=Param("upperlimit
sum",130,75,130,1);
Lowerlimit=Param("lowerlimit
sum",130,75,130,1);
size=Param("size",36,36,55,1);
a=0;b=0;Cc=0;d=0;e=0;f=0;Ctr=0;
for (a = 1; a < size-5; a++)
for (b
= a+1; b < size -4; b++)
for (Cc = b+1; Cc < size -3;
Cc++)
for (d = Cc+1; d < size -2;
d++)
for (e = d+1; e < size -1;
e++)
for (f = e+1; f < size;
f++)
{
Summ

if(Summ
<= Lowerlimit AND Summ >=
upperlimit)
Ctr=
Ctr+1;
}

AddTextColumn(WriteIf(Ctr

AddColumn(a,"a",1);

AddColumn(d,"d",1);

AddColumn(f,"f",1);
AddColumn(Summ,"sum",1);

Could someone look at this ....
my settings in AA window are as
follows:
current ticker
n last quotations
n=10
When I click explore I am expecting the
output to have 10 different combinations with the combinations equaling
130 ...
Thank you in advance
Anthony
