You are obviously not a "software engineer"... Since you imagine that processing terabytes of data... In real-time to be somehow trivial. Myself... I've been trading full time for 15 years... So parsing data feeds is not my idea of a good time. And if I needed this level of...

This.

NxCore is a classic example of "Artificial Stupidity"... I trade about 300 stocks and require << 5% of Consolidated NYSE messages... But these Clowns can only send the whole thing. Adding simple throttles... Like a list of symbols required... Needing updates only X times/second, etc...

Don't worry. Obama will say all the right things.

Dude, Mailwasher is so 2003... I had it 100 years ago... it's laughably hopeless. This may be hard for you to believe... But GMail virtually eliminates spam... Which proves that spam is an ISP conspiracy... To charge you extra for this or that. Really, read the link... and just get a...

That's EXACTLY what I said... This would only matter to black boxes. Last year I traded 37,000,000 shares... And netted slightly > $1 million... (The record volatility more than doubled my normal margins)... So if I got an extra 1/10 of a cent/share... That's only $37,000... Not enough...

This is virtually meaningless... They are talking amounts on the order of 1/10 of one cent. If you are doing ultra-high volume AUTOMATED algo trading... $0.001 may make a difference... But any core, HUMAN managed trading operation... Must have profit margins in the $0.01 to $0.02 per...

You guys should read some professional magazines... If you cannot follow your own order executions: The last line in this analisys of Reg NMS: "If I have a prediction for NMS, or the trade-through rule," Selway says, "it will continue to be whittled away by exemptions until it's...

Why would you just assume that? Everytime SMART routes me to ISE I cringe... Because it definitely affects my fill quality... Orders get hung up for even minutes, etc. For high volume scalping... You want maximum executions NEAR the NBBO... Not orders sent to Siberia in the hopes of...

The market is pricing both correctly... Any bond yielding > 40% is a much better indicator of impending bankruptcy... Than common trading as a penny stock. Sophisticated bond market traders... Are basically saying that in the inevitable GM reorganization... Which will really be a US...

Nice post... But it would be MUCH better if this was your 100th post. Also your co-ordinates are very important... Because nothing serious will be built long distance. And speaking as a software engineer... Professional level Quant System design excellence... Or in other words...

You will never be a successful trader... Because a great trader develops over MANY years... ONLY by learning from 100s of mistakes. You may as well quit right now... Or go join some crooked firm and run sleazy scams.

Clubber knows what he is talking about. If you don't have > 50% margins paying $0.003/share... At a first class broker... Then it DOES NOT MATTER how low it goes... Because you do not have a viable business model. If you business model depends on sub $0.003/share rates... You may as...

For trading you really have to buy a dock. For a measly $200-300... You can have a mouse, external keyboard, and 2 external monitors... And any half-decent graphics card will support two 1900 x 1200 monitors. It's not as if your gonna trade while skate-boarding. With such a simple...

These securities are too efficient... To trade profitably using infrastructure... That is as simplistic as yours. Your competition has: (1) Sub one millisecond latency. (2) Inside information. So you have no chance. Poker Pros always look for the softest game... But it never...

I get complete blackouts at least once a month... And have 3 PCs and 5 monitors... And several modems and routers... On 8 APC 1500 equivalent... Which gives me > 60 minutes of battery power. I have the Peplink 30 Triple WAN router... With cable and 2 DSL services... AND MY INTERNET HAS...

There is no where else to go... For Canadian Pro Traders... Because if you do 100,000 stock trades/year... NOTHING can compete with the lowest fees. If the OP doesn't like TWS... Then build a custom FIX platform you do... And if you that's out of your league... Then it really doesn't...

Oh, I see... You've "invented" a new way to manipulate the market... Or evade an NASD regulation... Something no one has EVER thought of before.

It's called "short against the box"... And it's still useful for VERY HARD TO BORROW securities. You never actually close your short position... Instead you buy long stock to offset it. When you sell the long you are short again. And no... IB does not allow this in one account.

I have 2 laptops that support Dual 24" 1920x1200 resolution... So the 2 laptops side-by-side drive 4 x 24" 1920x1200 resolution... Which is what I need in a portable system. The first is a ThinkPad T61p with Advanced Dock and Nvidia 570m graphics... The second is an HP 8530w with the 2008...
