Brian,
I want to add a custom metric to compare my total portfolio versus a
selected index. My guess was that I would write the first and last
entry date of my portfolio back test as a (static?)variable and then
take the ROC to compare with the portfolio's return. From there I
could expand to compare drawdown etc. However, I am no sure if that is
the best or most efficient way to compare.
Dingo mentioned a security by security comparison but I want to use
the total portfolio relative to a buy and hold as that is more
appropriate for what I want to measure.
I am open to ideas.
Thanks
DM
