Basically in their rulebook it says that all prop (as opposed to agency) flow must be passive, and if they find aggressive prop flow from a member they can terminate the membership. The tie in to IEX is tenuous at best.

One big factor in the success of these ETFs is automation (aka HFT). You don't get SPY quoted in size at a penny spread without the massive investments in research and technology on the part of the ETF market makers.

Yeah for a given price, fully hidden and the non-displayed portion of iceberg orders will be ranked (generally by time priority) behind any displayed shares. Most of the rules are meant to incentivize displayed size.

1) A U.S. equities exchange has to be registered with and approved by the SEC. There are currently 12 of them. As a registered exchange you have to play by certain rules, and in exchange your displayed top of of book is subject to the order

This is almost right. NYSE and Arca are two separate exchanges (both owned by NYSE). Both exchanges offer FIX and binary gateway protocols. Annoyingly, the Arca binary protocol and the NYSE binary protocol are not the same protocol. NYSE do

The pay in these sorts of articles is always overhyped. As with any business, the people making the most money at these kinds of firms are the owners of the firms. Consider this line “As a trader, if you do well, you will retire before you

I think the other thing that changed is that branch predictors are roughly infinitely times better than they were in 1980. The is-this-subscript-ok check should be easily predictable and I wonder if these checks even cost anything in a hot

The rate difference only benefits hedge funds if USDJPY also plays along. That trade has fx risk and you're making it sound like a sure thing. If USDJPY goes the wrong way, the trade loses money and the average joe whose savings accoun

A leveraged fx position and an interest bearing savings account have very different risk profiles and it seems silly to compare the two.

It kind of sounds like Zenefits is looking at some heavy (multi million dollar) fines, and they're trying to drive the narrative before fines and regulatory actions are announced.

Yes. It's because of the idiotic way the Dow formula works. The Dow is a price weighted index. To compute the value of the Dow, you sum the per-share prices of the constituents and divide by a magic divisor. So a $50 move in GOOG (~6.6

Do you think there are monopolies in electronic market making? I think there are tons of firms out there trying to be good at it in different asset classes, and a few that are really good at it in lots of asset classes. I'm not sure

I thought you were making the argument that reducing tick sizes would reduce the amount of effort put into reducing latency (or reducing the overall amount of prop HFT volume), but I guess I was wrong about that. The idea that reducing tick

I think a better way to change exchanges is to dramatically decimalize the price levels. The idea that reduced tick sizes would force traders to compete on price rather than time is a popular HN market microstructure solution, but it'

According to the Stephan Brumme website you linked to, the slice-by-8 lookup table is 8K and the slice-by-16 table is 16K, so your combo version of crc32 needs 24K of L1 cache to run at full speed. Modern server class CPUs typically have 32

I read more about the slice-by-N algorithms because they sounded really interesting. The way they work is by using a set of lookup tables that are 4k to 16k in size (larger lookup table for larger N). The reason they are fast is because the
