Sure, you could say that the pragmatism behind that belief is a little off, but I am convinced that there is too much money involved in
the game of high frequency trading to see its growth slow down or taper off now.
There are 2 Issues I see that the article makes: 1 > Negative - Sum -
Game: Isn't someone who's an intra-day trader or even a
high frequency trader doing the same thing in Equity markets 2 > Leverage: The Idea
of options is based on leverage, and apparently option
trading has shown to reduce volatility.
