Re: [amibroker] Re: Accumulate values across symbols

you could try this for the number of up bars in current day up to the selected bar on the chart

upbars = sum( C>O, barssince( datenum()!=ref(datenum(),-1) )+1 );
// I have added the +1 because sum includes the current bar and the barssince starts at zero

to get the total for the entire day selcted you woul need to filter on the last bar of the day, ie
filter = datenum()!=ref(datenum(),1) or barindex()==(barcount-1);

or use this to count the entiire day for any bar selected
upbars = valuewhen( datenum()!=ref(datenum(),1) or barindex()==(barcount-1), sum( C>O, barssince( datenum()!=ref(datenum(),-1) )+1 ), 0 );

Thanks Terry.  I was hoping for an easier way, but I guess this will work.
