Quote from garchbrooks:
In all seriousness, in modern automated trading, the execution performance is worth more than the strategy. The platform facilitates models, the models don't facilitate the platform. The business types try to maintain the mystique, but this is changing.
My suspicion is that the real reason the industry is fighting so hard against the automated guys is because they know that once the government steps in, it goes away from being a meritocracy back to the "good ol' boys" club, where profits are a function of deal-making more so than raw quantitative and computational elegance. Automated trading was the best thing that ever happened to the markets, and as you know, government has a habit of ruining things in this country (the US.)
In terms of market insight, it's really a question of whether the programmer has the drive or not. The job of "trader" is done for, unless that trader has some special quantitative ability or programming ability that can work magic with simple ideas.
