They can be described in a single sentence, but detecting the difference between spoofing and legitimate activity can be very difficult, especially when some participants are trading cross-border and cross-asset; their orders are reacting t

I know that ISE had some sort of automatic cancellation feature from the beginning or very close to the beginning, so not sure if PHLX was the originator of this idea. Also, nearly all electronic options exchanges have a "mass quote&q

I've worked in automated option market making in the past; if I were on a jury hearing this case, there's no way I would convict these guys of spoofing. They are taking advantage of a feature built in to the market for purposes s

Author has things reversed. Automation is affecting jobs with higher wages and higher productivity first, turning those markets into winner take all or eliminating labor altogether. The remaining workers are forced to crowd into lower pro

Fortunately, tax law has been made so complex that the Supreme Court eventually decided that ignorance is a defense: https://en.wikipedia.org/wiki/Cheek_v._United_States So you may end up with penalties and interest, b

You have to assume that the brokerage must retain and report the information, otherwise you can lie all you want about your cost basis without any way for the IRS to cross check at scale. If caught in an audit, you can just claim a bookkee

Frankly, we ended up with the cure AND the disease. Special purpose entities were used by Enron to muddy up its accounting so nobody could tell that it was doing stupid deals to hit its quarterly numbers and wasn't really making any m

I use a Happy Hacker keyboard in a customized emacs environment, but I'm pretty much Linux only, so no issues with transition between laptop and desktop, although I do have an older Thinkpad and the layout is slightly different, but no

I think we will start to see less use of GCs in mobile going forward, especially now that Apple has deprecated GC in favor of automatic reference counting. The issues caused by the interaction between the memory hierarchy and the fragmenta

"You're never going to see a power tool or a tractor or whatever designed in OpenSCAD." I beg to differ on this, I've been using OpenSCAD for a couple of years now, and the two most complicated designs I have done were f

I've met some of the guys from Ufora and seen a demo of their technology; very impressive. I've always been leery of the claim that you can create smart software to make the problems of writing parallel code magically disappear,

I believe 100% in proactive error prevention as a means of building robust programs but, as you say, there are failures that cannot be handled this way; when the kernel fails (as in this case) or when the hardware fails (e.g. spontaneous bi

All kinds of badness here. Bug #2 really reduces the level of comfort I would have with using ZooKeeper as a tool. First of all, the default Java policy of terminating the thread, instead of the process, when a runtime exception is not han

What you are describing is manipulation of what I've seen called "book" or "depth" micro price; the sort of thing that got Trillium in trouble ( http://www.reuters.com/article/2010/09/1

What is the definition of "layering" here? I've seen this label applied to a technique that is used to ensure that orders are at or near the front of the queue on a price/time priority exchange as the market is moving.

You are ignoring the temporal element of the market; in the short term, prices are set by supply and demand, and trading to match supply and demand is exactly how market makers earn profits. The true value of a security can only be determi

This is exactly the case, and it's why "painting the tape" has rightfully been illegal for quite some time.

Actually, what they've really got him on is him explaining the scheme in detail to a broker-dealer, describing it as, essentially, a conspiracy to manipulate the market and defraud other investors. This is much different than a case w

Amazon should clearly buy this company and mount an attack on the PBMs; automatic delivery of this sort of product would fit well with their core competencies. They could also come out with their own versions of store-brand generic over-th

More like the Saudis are driving the price down partly in order to inflict damage on the Iranians, with whom they are engaged in something close to a cold war, but mostly to choke out the high cost producers in the US and make future invest

Fudging the inflation numbers has been coming on for a while now; I call it the "screw the old people and the foreigners" strategy. As for the issues with GAAP, I can't understand why the holes in off-balance-sheet accounting
