[amibroker] basic question

[trdrync]

Hi,

I am trying to run explore with a set of conditions .. something like

for (...)
{
   Filter = cond1 and cond2;
   if (Filter)
       break;
}

As Filter is an array I cannot use the above code and I cannot use
selectedvalue(Filter) as I discovered that it always returns the last
value in the array. How do I determine the barnumber that is being
processed at present so that I can use Filter[presentBar]?  For ex: if
I set the value of 'n last quotations' to 2, how do I determine if the
code is evaluating n or n-1 bar? Am I missing something basic?

Thanks,

Naveen
