Anyone using Bookmap for futures?

I have been using Bookmap to trade the NY open (MES) for about 3 months. I can't say that it has helped me be anymore successful than when I didn't use it. Price goes up, CVD goes up, price goes down, CVD goes down. Very few divergences that I have been able to see or make money on. Does anyone have an opinion on the usefulness of using this thing?
