This is THE major concern and would cause serious ripples. The bigger HFT players are lobbying hard against it. We've done some sums and can absorb the proposed tax but it's going to hurt. I imagine the rebate boys would really feel it though, but they have friends in the right places so I can't...
I'm glad a few people here get it. Most of the folks on this site seem to be either slightly simple or hopelessly naive.
To be absolutely clear, we (and I can only speak for my firm) don't intentionally front run. We use ISO orders which, due to systemic problems with the way in which Reg NMS...
What the fuck is it with this site? Read what I actually wrote. Using ISO orders does not always result in violating time priority. It is sometimes a side effect. We're not going to stop using ISO orders because we want the behaviour they provide. If the SEC sort out the fiasco that Reg NMS has...
Please show me where it states MMs (in any market) must quote 100% of the time. MMs can shut up shop just the same as anyone else if things get really rough. They aren't going to slit their own throats just so you can puke your position.
Interesting how you decided to edit your post as soon as I posted that Tradeworx doc. What was the point of that?
The ISO issue is something that Tradeworx and others like them have been banging on about for a while now. As I think it says in the doc, a lot of us end up jumping the queue...
That's a bit like asking 'how long is a piece of string?' It varies enormously depending on the firm. Most of them are privately owned so the exact figures aren't generally known. Getco and Citadel are each rumoured to pull in $500m+ p.a. though.
Tradeworx have got a good doc on their site we...
Of course they take losses. No losing days does not equal no losing trades. Explain to me how, now flash orders are out the picture, they are front running?
Anyone, yes even you, can rent a server these days in a data center within 500m of any major exchange for no more than a few hundred...
Hmmmmm, big outside blow offs...is that even legal?
Whatever you choose to call them they indicate the same underlying market dynamics.
But the question is, why use bars at all? Show me a sequence of bars on your chart, I'll change your baseline period or offset and show you a totally...
