I was not thinking of that, but your
scenario is along the same lines and would be a another important option.
I was actually thinking of the problem from 180 degrees around.
Specifically, for a dataset of, for example, 1000 bars optimize only over
the last 500 and display the equity curve for that range. It is possible
to only consider (and display) the equity for a specified number of bars (e.g.,
the last 500 bars), but I don't see how to restrict optimization to those
bars. Certainly not with the available arguments for
Optimize.
