The figures are correct but I think you're talking at cross-purposes, you from a solo bettor trying to get down perspective and he's looking at total volume traded (which appears to be low), and the inherent risks that implies.
MB Volume will however inevitably be lower because of the moronic commission structure. A fair chunk of the volume traded at BF will be the same people dipping in/out of the market to manufacture prices, arbitrage etc. Those people won't play at MB because a charge on every trade (vs net profit) kills the margin.
