Most of it is sub-penny "price improvement" on the part of payment-for-order-flow "wholesalers" (who are in fact the largest of the HFT's, such as...
I agree with most of your sentiments, but IEX has "broker preferencing" (queue jumping for the "right participants"), if IEX is approved as an...
There are an infinite number of possibilities. You will have to decide for yourself. It gets a lot trickier the wider the spread and the less...
I'm not sure if many individuals do this, but I'm sure the quant hedge funds do. The dollar amounts applied to these longer-term quant strategies...
I am not totally sure, but it sounds to me like you probably would need to decouple your strategies from NinjaTrader, which would require...
I've used lots of distros and there seems little difference from my point of view. I have used many versions of Wine as well, and I don't think I...
I've been running NxCore for years under Linux in full production; I just rebooted a server that ran NxCore uninterrupted since December 2013 (the...
There's nothing inherently difficult running mixed-OS systems as such. Wine, VMWare, and multiple servers are all feasible for this; there may be...
In any event, I think it would certainly make sense for the SEC to figure out exactly who it was who made those trades, and what connection they...
At least the new microcap pilot program will banish sub-pennying for one portion of the test....
If you're talking about US markets, Nanex NxCore can do this with ease, but will cost you something in the low $1000's per month (requiring a 1...
It's not surprising to me, given that dark pools are now executing lots of small trades, rather than the blocks they were supposedly created to...
NxCore can do this but is significantly more expensive than IQFeed (at least the default IQFeed). It is a strictly API type of system that gives...
I don't know what the microstructure of the markets you traded in the past, but I am pretty sure it's very different than that of US equities. If...
IEX allows for queue jumping -- my guess is that that's the "carrot" they used to get major B/D's to support them. (Why would large B/D's support...
"except for quote updates from market makers" -- how convenient for IB; IB's Timber Hill is a market maker and an HFT. So he's proposing a rule...
"The game" of trading more effectively is fine by me, but I don't much like the practice of manipulating the rules of "the game" in order to gain...
"broker preferencing" (which is really queue jumping) looks really bad to me. As if we didn't have enough to deal with, with internalization,...
I'd guess the ban is due to the fact that an ETN can track pretty much anything, so giving a client a large amount of margin to buy one could...
If you're talking about trades going through your hidden orders in general, then the largest culprit is probably...
