Dear mladen im trying to call the arrows of this indicator with iCustom function but not luck. What im doing wrong?

Thanks a lot.

double HA(int i)
{
double up = iCustom(NULL,0,"Heiken Ashi Ma T3 new 2",4,i)!=0;
double dn = iCustom(NULL,0,"Heiken Ashi Ma T3 new 2",5,i)!=0;

if(up)
{
return(1);
}
if(dn)
{
return(-1);
}

return(0);
}
