Re: [amibroker] OT: random combinations

Hi Anthony,

 

Your For statements are not doing anything. If you mean to nest them, you need to remove the semicolen after each For statement, as AB interprets that as the end of the statement.

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

 

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);
