First thing I always do is check Alexa traffic: http://www.alexa.com/data/details/traffic_details/cqg.com?q= Obviously based in Latvia... 25-30% of traffic from Eastern Europe. Not a bad traffic profile actually... But when you click on the "3y" graph... You see a big dropoff in...

It's not DTN... It's just one guy with an idea and a website. Unfortunately... The the product is so "sophisticated"... That you can either get 100% of the data for an exchange or 0%... Nice binary decision. Like I really wanna process 20,000 ticks/second from the NYSE... When I need...

It's nothing to be concerned about... Just "some trades that went awry"... So reports the lapdog financial media.

(1) Assume >>> 90% random walk. (2) Flat cost/trade sub-optimal in today's fragmented market. (3) If you are such a poor trader that you have bid-ask "slippage"... quit right now. You must profit from the spread to be competitive... That means > 90% limit orders. (4) Focus on a...

Nice try... but this is VERY faulty logic. Also, using one example is too simplistic. (So 2 big problems). REALITY If you employ market orders... Your additional cost will be... 50% of the average spread for that stock... PLUS brokers and market makers will ** cheat ** for $0.01 or...

Let me explain. If the markets were perfectly "efficient"... It would be impossible for anyone to profit... (without cheating). But the markets have countless "inefficiencies"... And 1000s of trading operations are consistently profitable. ALL profitable operations exploit a specific...

Yes... that is the correct order. (1) "Find an edge"... Usually something creative... Something relatively few people are doing... By definition... this means exploiting a market inefficiency. (2) Trade profitably using your "edge" for months or years... Becoming a great trader over...

It's an interesting article... But what journalists think is of absolutely no importance. One has to look at typical INVESTMENT GRADE corporate debt... And see how MBIA or AMBAC insured debt is trading: These are rough figures last several months: US 10 Year Note: UP 6-7% MBIA...

Custom data structures... Are always much faster than any off-the-shelf database.

The thread title is ludicrous. Ron Paul has nothing new to say... It's just the laissez faire Party Line. Bernanke is bored to freaking death with Paul... Because he simply disagrees with Paul.

You are limiting your search to low budget Tier II data providers. It's oxymoronic to care about latency... But be unwilling to pay for expensive low latency infrastructure. You have to go with Reuters or Thomson and off-the-shelf products such as this one...

This is called "backing away"... and is totally freaking illegal... But it happens all the time... And you have to live with it. I'm sure that just about anything goes after hours. Countless forms of market manipulation happen all the time... And nobody cares... So your business model...

Agree with this. I have yet to see any legit performance numbers for these algo systems... It's really nothing that you cannot read about in 15 year old AI papers. I flat out do not believe the story: "I'm not an experienced trader... But I'm a software genius... Blah, blah, blah"...

Exactly. Early November has been an almost exact replay of mid-August. Since we are talking ** Zero Sum Game **, a lot of people made windfall profits in August. The same people cleaned up last week. If you lost money in August - you should have evolved enough to be making money in November.

I was talking about the NYSE... Which has a specific regulation that kicks in at 10:1... And is enforced on a discretionary basis... Against idiots that abuse the system. But never mind... You have nothing to worry about in terms of your "imaginary strategies".

This has got to be a new low for ET. Some ass clown in a Third World Hell Hole claims he is not a "criminal"... But pulls a dozen regulatory "facts" out of his ass... For the sole purpose of EVADING TAXATION. And then someone who should clearly have better things to do... Actually...

This is an outrageous amount... Something on the order of $0.01 might be what exchanges could get away with charging. I have never been charged a cancellation fee... But on the NYSE one must approach a 10:1 ratio of cancels vs fills to for anyone to flag you. Generally... Only ** very...

Thank you, Rockfish. One basic problem that I have... Is the standard, predictable IB position that a basic service = "frill"... And it is out of the question to make "low costs" possible. FACT IB profits $700 million/year with OBSCENE margins roughly 50%... Probably more than double...

Thank you for pointing this out. IB was asked for a link in this thread. Def did not provide one... But just acidly stated that IB does not provide "frills", etc. So it was left to you to provide a link. As for the "securing a network" part... A non-engineer would have no clue... As...

This is a completely naive and irresponsible statement. It is not possible for a non-engineer to "secure" a computer network. Even an engineer... Could not positively "secure" a network against a determined, targeted attack. IB has 500 employees... Of whom probably 50 have access to all...
