A veteran programmer explains how the stock market became “rigged”

So its good for the trader who wants to do that. Is there any benefits to the market overall that he wants to do that?

Edit: Can someone explain to me why I am being down voted from asking a question? It seems like every time I get into a discussion with yummyfajitas I am being down voted?

Allowing a trader to make large trades makes price discovery happen faster and more accurately. I've written a more detailed explanation on my blog - read HFT apology 1 and 2.

As for the downvotes, I lead a small cult of traders, rationalists and scala programmers - tptacek is my #2 sycophant.

So again the trader not the market/society.

Whats the benefit outside the stock market to society in general? I.e. how is HFT a net profit to other than those involved in HFT?

You are asking people to be specific, can you you?

You must be able to give examples.

An example is provided in part 2 of the tutorial. Are you demanding I copy&paste it here?

o.O

Amusingly: this comment was downvoted 8 minutes after I posted it, despite the thread being 6 days off the front page. :)

Yes: limit orders provide liquidity, and market orders sap it.
