[amibroker] Re: CLOSE value can it be change via a afl scan. if so how i would i do it

["nickhere" <nickhere@xxxxxxxxxxx>]

I was going to use it as value in a composite ticker then after the 
run use the new single field in a commentary.
i did  fiqure out how to do it in ole
but notice that there is a bug
volume and openint are int values 
not single as stated.
also when using this and when trying the add to composite method 
(which i couldnt get working) the open and close must be equal or 
between the high and low value(make sense). Also why is the volume 
from yahoo trunicated by 100

here the way to update the composite database

st=Status("barinrange");
b=SetForeign("~nick");
if (b==0)
{
AddToComposite(0 ,"~nick", "X",16);  //set composite
}
Filter=Close>=0;
b=SetForeign("~nick");
if (b=1)
{
for( i = 0; i < BarCount; i++ )
{
if (Filter[i]==1 AND st[i]==1)
{
AB = CreateObject("Broker.Application"); 
AA = AB.Stocks();                         //aa.count=numberof tickers
stocklast=AA.item(AA.Count-1);            //last stock is now the 
object usually your composite
loc1=stocklast.Quotations(BarCount-1);    //quote location of where 
you want to change
loc2=stocklast.Quotations(BarCount-2);    //quote location of where 
you want to change
loc3=stocklast.Quotations(BarCount-3);    //quote location of where 
you want to change
loc4=stocklast.Quotations(BarCount-4);    //quote location of where 
you want to change
loc1.OpenInt=loc1.OpenInt+1;
loc2.volume=90.10;
loc3.low=900.1;
loc4.high=8.90;
}
}
}

NumColumns=1;
