co-location at the exchanhe sounds good, but what if you want to reach more than one exchange? what if you want INET, ARCA, NYSE, BATS, and more? How would you go about co-loing and managing that whole thing? I don't necessarily thin that co-lo at the exchange is best. There are brokers...

he is looking for data feed as well as executions. There are plenty of places that claim to offe rlow latency data. The question was about data and trading, or execution. It's a good thread, let's keep it on track, shall we?? There is a lot of places that do this, but few do it well, and...

quick, what do they have in the pipeline? and also, how long does 100 mil last if you don't have anything in the pipeline? how many biottech companies are in this space? Why would you now enter in here as a LT investor when you can find someone else who does have something in Phase 2 or...

so your telling me a failed drug trial that is the entire basis of the valuation of this stock isn't important? No? Wow. Remind me to chime in more often....have fun with your candlesticks. I really hope the Elliott Wave can explain your next biotech blow up. Egads. Your factors may...

fundamentals may have something to do with this, I'm amazed no one either cares or has chimed in. This stock is based entirely on a binary event. Lots of work done to figure out that this thing was a likely dog, but if the bibnary event/trial was YES, it blows up on you as well, to the...

PM me, as I have someone that helps me out. Thanks.

You guys must drive really bad cars....some of the products mentioned here are so clunky, so second rate, and so slow, I'm amazed they even hit this thread. Maybe you've mentioned two or so places/products used by institutions or people looking for high speeds, low latencies, relaibe...

volume high and size low is gaming? It's stat-arb flow. Large difference.....focus on the "alrge volume part"....

.0025 fee to take away, .0023 rebate to post liquidity. Yes, it's an ECN.

ping isn't half the story. Yourt order needs ot come across the water, and then internally STOP at the broker for checks vs. easy to borrow, margin,and maybe disaster recovery, and then be sent to the ECN or exchange. then, the latency per exchange varies wildly by their matching technology...

how do you all plan to use this type of data in an Reg NMS trade through scenario? Effectively, if you're looking for NBBO, how do you plan on this method of data dissemination to be useful if not detrimental to your trading?? Don't slander away, it's a great question to think about....

if you need latency data, and that being for data as well as round trip for internal processing time as well as round trip of your order from server through brokerage, off to trading venue/ECN/exchange and back, your broker or most savvy brokers would be HAPPY to provide that. If not, or the...

they're mostly automated, all in house, and probabyl trade closer to 2 bil shares a month than one. Getco LLC. I'm sure they're up there in terms of liquidity providers, but not at the top. Nasdaq website now releasing a monthly list of leading liquidity providers, an interesting list...

It depends what you want out of the quotes, but there are some differences/advantages, and you also have to drag NQDS intot he comparison. TotalView provides different depth levels and includes some ECN data (BRUT, SUMO, TRAC) beyond the top bid or ask. Level2 and NQDS provide similar...

isolating the brokers part of the equation for latency is what programmers want to do. They don't want to be told that the broker's smart router is nifty. They want to isolate exchange latencies, broker latencies, and overall latencies contributed by where servers are, etc. It's up to the...

there is no criticism, I'm saying that "smart routing", if I'm to believe what is writtn, and what you say, introduces latency into the equation. That's my point. Anything any broker ever (including the infallable IB and others just as great) does to "try to help" slows thigs down. Again...

If you choose to detract from the fact that direct routing is $1.75, feel free. That semed to be the original question posted here. All "smart" routing on anything, anywhere, any time, adds latency.

my post states nothing of the sort. the decision where to route should only take an instant, yes, but I believe it is your website that mentions 10 seconds. I think most of us here are aware to check all the regionals, etc, it can take time. If you're just going to best of book, maybe, sure...

milliseconds in options trading, checking all the regionals? I'd like to see those figures...... It's more in the order of seconds, I'm sure. $1.75 direct, though, right, no tiers?

Interactive brokers charges $1.75 a contract for direct routing, yes? That other .75 is for "smart routing", yes? If you want to go direct, it seems to be a lot more. Am I missing something here? Smart routing can take up to 10 seconds, right?
