I have several automated strategies that I am back and forward testing. There is one in particular that relies on morning volatility / reversals. This one was a consistent money loser up until the beginning of August, when the VIX shot up. Since then the consistency of this algorithm over the last 50 days or so is quite amazing. When I plot the profit curve for the year, it is a V shape with consistent losses up until August, then consistent gains since then (of course there are losing days even post August, but the expected value of the algorithm appears to have turned positive). Anybody else seeing something like this?
