On: Is the U.S. stock market rigged? [video]

Uhh ignorant HNer here. What is your tick to trade latency? What are your fill rates like? Are you doing primarily add or take? Which contracts do you trade? :-)

*I'm not going to answer these questions for the system I currently work on as it would violate IP agreements.

Tick to Trade Latency: Are you asking about my average times, my median times, my 2 9s or my 4 9s;)? Basically call it tens of mikes.

Fill rates: I've worked on systems that fill on nearly every order they place and other systems that skirt with getting banned.

Adding/Taking liquidity: Mostly adding liquidity in my experience, but I have worked on strategies that only take.

Contracts: All the ones that make money, none of the ones that don't.

> other systems that skirt with getting banned.

That sounds a lot like the "price discovery" flavor of securities fraud.

[kasey_junk → judk]

Not to be flippant, but price discovery is not a fraudulent issue in the markets I trade. That said, the exchanges I trade on, are much, much, much more diligent than the relevant governmental agencies.

I won't pass a value judgement on that.
