The sliding window feature gives you a much better idea of whether a search is good or just had a statistical outlier (got lucky). This feature would be of tremendous value in VV 7 or in the simulator. Rather than just giving you a return from point A to point B, it tells you the average of all trading periods that you can adjust (i.e. 10 day 20 day etc) at will. This is far more useful than just the return from point A to point B. This would make back testing far more reliable for any time period.
