Fines should be much higher to have any effect, but it will not really change the game. I feel little empathy for other parties who have lost money because of this, the whole system seems to have become an arms race between mathematicians/programmers, where the most audacious one (who does not get caught) wins. There is no economic value in any of this. I think trading in derivatives as a whole is too cheap: reading the article it seems trading against yourself is cheap enough to use it to manipulate others. Taxing derivative trading (I say casino tax but any small percentage would work) would stop all this nonsense trading instantly, only leaving trading that is actually valuable to someone.
