[amibroker] How to get current per bar Equity in CBI

[dmcleod1981]

I am trying out some position weightings but was unable to figure out
how to find the current equity at the point where the trade is done. I
want to add a metric of Percent per equity but when I use Equity() it
gives me to ending total. I thought by using something like:  
for(i=0; i < BarCount; i++)
       {
               CurrentEquity = bo.Equity; etc etc

I would get the number I need but I am obviously not using this
correctly. Any pointers or samples?

Thanks,
DM
