It doesn't mean anything for Chicago. "NYSE Chicago" is an electronic exchange hosted in New Jersey. It has Chicago in the name because NYSE bought the old Chicago Stock Exchange in 2018 (which was partially hosted in Chicago

Your description of market making is backwards. If you're buying the ask and selling the bid, you're paying the spread not collecting it.

It doesn't happen. All the exchanges have a "Day" order type that you can send before 9:30 that will be live on the book when it opens at 9:30 (or transitions to the "core" session at 9:30, most US exchanges have a

> The NYSE runs out of a public data centre (called NY4) which is run by Equinix. No. NY4 is in Secaucus. NYSE operates out of an ICE (NYSE parent co) owned facility in Mahwah about 25 miles north of there. They managed to pick out the o

Yes, exactly. Fidelity is a private company just like Reddit and Discord are. There are still shares in the private company held by various owners, but the shares aren't traded publicly, which is what it means to be a public company.

Why did you feel the need to support trading of non-LTSE listed names on the LTSE? Are there novel order types or other trading mechanics coming down the pipe?

You can't really "front run" a retail order. Front running means you (assuming you are an agency broker) get a big market moving order from a customer, do a trade in your own account first (in the same direction as the custom

Can anyone suggest a good book that would serve as an introduction to finite field arithmetic? I keep randomly running into it (e.g. this post), but don't understand it well enough to follow the discussion.

All the transactions detailed in the SEC order are outright sales of stock (not options). He was both selling stock he already owned to avoid losses and selling short to generate additional profit. Before it was acquired, AFOP never had a v

The XIV is (was) meant to track the daily inverse of (roughly) the same underlying index as VXX. So a 10% up day for the index should be 10% up for VXX and 10% down for XIV. Now we can plug in rough approximations for Monday 2/5 and

Lots of people trade physically settled commodities futures contracts without handling the underlying products. You just have to make sure you close or roll your position before it settles.

The article isn't about trade throughs. It's an unconvincing argument that rebates bad and that IEX is good because it does not use rebates (while failing to mention any other exchanges that don't pay rebates).

How is that a fix? A market with huge displayed sizes but no trading (because nobody wants to pay the massive take penalty) is not a "liquid" market.

0.5% on equities was the Bernie proposal. Here I'm assuming that both sides pay 0.5% but even if it's half that (each side paying 0.25% or only one side pays) the numbers are crazy.

Here are some numbers. 0.5% of a $50 stock is $0.25. So to break even on the tax alone you need to sell $.50 higher than you buy. That alone will blow out the spread any market maker is able to quote at. The other problem is that now scratc

The real reason the article is unserious is because IEX is basically purpose built to game the execution quality metric they're looking at (effective spread... trade price vs NBBO midpoint). Imagine you built a dark pool that only exec

I think that's about half right. A 0.5% tax on all equities trades, which is what Bernie was proposing, would put a bunch of HFTs out of business basically overnight and at the same time dramatically increase costs for investors via 1)

Any reasonably good optimizing compiler will implement that switch statement as a jump table so it's really just one conditional branch even though it doesn't look like it.

My understanding is that nothing serious has gone wrong, so far, in nearly two years. GBTC is a bad way to trade bitcoin and the chart in reference [2] you posted shows exactly why. A good BTC tracking ETF would have NAV = market cap, but
