Re: [amibroker] OT: random combinations

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

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?

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 = a + b + Cc + d + e + f;
      if(Summ <= Lowerlimit AND Summ >= upperlimit)
       Ctr= Ctr+1;
     }

 

Filter=1;
AddTextColumn(WriteIf(Ctr >0,"Combination ","")+Ctr,"ctr",1);
AddColumn(a,"a",1);
AddColumn(b,"b",1);
AddColumn(Cc,"c",1);
AddColumn(d,"d",1);
AddColumn(e,"e",1);
AddColumn(f,"f",1);
AddColumn(Summ,"sum",1);

Subject: [amibroker] OT: random combinations

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
