HFT / Fund guy here. This is marketing spiel. If you just want to trade on a bunch of exchanges so no information flows between them, you can easily (TM) write a program that either a) lines up the orders at each exchange to execute at a specific time or b) delays the orders from a central server by the line delay. So say NYC is 13ms from Chicago. You want to hit both at once. As long as you're not 13 ms late, nobody…
Does RenTech still have investors? I thought they worked for themselves now.

It's worth nothing that eating into Renaissance's profits in this way is good for everyone else because it means that accurate prices are reaching the market faster.
You could say the same thing about insider trading. So, the argument that accurate prices reach the market faster is not, in and of itself, an argument that something is good.

#133This reminds me of how Google uses atomic clock and GPS for Spanner [1] Google: "“We can commit data at two different locations — say the West Coast [of the United States] and Europe — and still have some agreed upon ordering between them,” Fikes says, “So, if the West Coast write happens first and then the one in Europe happens, the whole system knows that — and there’s no possibility of them being viewed in a diffe…
It's also the method by which signals from radio telescopes thousands of miles apart have been correlated after the fact at a central location. This has been the case for a couple of decades now. For instance, at the VLBA: https://en.wikipedia.org/wiki/Very_Long_Baseline_Array

> and still have some agreed upon ordering between them Funnily, that works only if the two observers are in rest relative to each other, as relativity theory tells us. :-)

Except that the state of art in HFT is sub-microseconds "London-based trading technology company Fixnetix said Tuesday it has the world’s fastest trading application, a microchip that prepares a trade in 740 billionths of a second, or nanoseconds." (WSJ, 2011) http://blogs.wsj.com/marketbeat/2011/06/14/wall-streets-need... http://stackoverflow.com/questions/17256040/how-fast-is-stat...
Isn't the relevant delay rather that of a signal traveling from one exchange to another?
That said, the Fixnetix stuff is only talking about one aspect of what's involved, and about as representative of reality as Cisco's published WARP speed figures in their Nexus 3500 range.

They do, the famous fund is Medallion, which is internal only. There's other funds that aren't quite as sexy.
Oh, I see. Why are they split up into multiple funds?

> Buy same security faster than rest of buy order can be processed. How? You can't because your competition is already resting orders there (from potentially weeks ago) and any order you put in there will be behind your competitors no matter how fast you are. What does happen is that you all are resting orders up and down the order book. When a big order takes out several levels of your orders, you race as fast as po…
Would eliminating the sub-penny rule remove the need to use this strategy? If there were basically an infinite number of points orders could be resting, you could just get in an epsilon above or below some other fund's order to get ahead in the queue?

What you are describing is an acausal (i.e. physically impossible, since cause effect happens before cause) version of demand anticipation - changing prices in response to market demand. It's impossible because the HFT will only know your order has reached exchange A after exchange A has told him about it. Obviously A can't tell him about it until after your order has arrived. Front running is a strategy where your b…
Did you not read my example? We are talking here about multiple, physically separated exchanges. Example: Vanguard sends a buy order of 1000 shares of AAPL to exchange A. Some HFT firm sees that order on exchange A and knows that it will also be placed on exchange B, and was surely broadcast from Vanguard's trading floor at the exact same moment as the order to exchange A. However, the HFT firm also knows that Vangua…
B) he is reacting specifically to the term front-running which has a known technical definition in trading and cannot happen the way you describe (I've said elsewhere I believe the term has been appropriated and redefined and am not willing to fight that anymore, maybe he is).
C) it's funny that you mention Vanguard as they have been pretty adamant that HFT market makers of the form that use latency are save them money.
