dear nitro: i myself have thrown lots of programming time because of poor design. now i am wiser and i spend more time in the design/prototyping stage. i sure have nothing against throwing code because you learn things on the way, but sometimes people have to throw code because of bad choices...

that's right, a lot of time is spent in idiosyncracies. i guess 30,000 hours is an accurate assessment if you have to figure out all those things and had to trash several versions and start again from scratch. as a fun story, there is an open source C++ application out there (i won't mention...

metooxx: not all so-called "systems" are trivial. the data part and the execution are difficult problems, but any decent programmer can solve them. the problems are basically idiosyncracies in hardware/data provider/broker interface and lack of documentation, not so much because it's an...

I've used Matlab intensively, it has a number of limitations for really big projects, it's not evident at first, and it takes too long to explain. The biggest limitation is that there is no data-management included. But it's very useful for "small" research projects. Don't bother about using it...

vladiator, my 0.02: i) Be patient, arbitrage opportunities will always be there (hey you are a finance phd so you have read grossman and stiglitz, havent ya?), so there is plenty of time to plan carefully your strategy before you actually put money and your reputation on the line, yeah i know...

that webpage was deleted a few days ago. but it's still on google's cache, go to google.com's advanced search, put "charity" in terms to look for and holdbrotherscharity.com in site or domain, search, then just click on google's cache of the pages that come up. take a peek before the hold...

Craig, the last part sounds interesting, does certain firm called A**X-futures offers it?

i am posting this so craig doesn't have to :D yes, it is called j-trader's P.I.G. price injector gun. i think it's in any j-trader manual covering the gold version, sorry no weblinks allowed :D

DblArrow thanks a lot for the info

or not... :D you can always place a tail-event trade a la Nassim Taleb....

Pabst: great advice! you are right! In fact, this is another reason why I still would prefer daytrading margins, to keep as little money as possible tied with my broker... of course I wouldn't keep 100% of my trading capital with ANY broker. Let's do the numbers, let's say I have 100K to...

DblArrow: who's your broker? how much the commish, which software? how about connection reliability, phone backup, etc.? thanks

Pabst: could you expand about the shops giving daytrading margins that you don't like, or at least give clues who are they? is any of them offering J-trader? Does any of them has a "history" at the NFA? I think all futures daytraders present here would appreciate it. Yes, it's not advisable...

Most brokers offering day trading margins revert margins at 4:15 EST. IB, reverting at 3:50, is the exception. Makes you wonder why.

babak: check http://toolkit.taltrade.com/ you need to program your own application (in C++?) to retrieve the data "as realtick does", analyze them any way you want etc.

Brutus: My feeling is that a mechanical trader is just a computer-assisted discretionary trader, nitro said that you have to know how to trade already in order to build mechanical systems, I agree 100%. But there are exceptions, Prediction Company research team built profitable automated...

Baron: we are trying to help. One of the things that made this board so great was unbiasedness. Look for example to the Ziff-Davies example. They try to keep or at least try to give the impression of impartiality, no matter how much sponsors pay. The day PCmagazine or whatever loses its...

Exactly. Another good reason.

It's breaking, this forum is starting to look like some other (very low quality) boards. Sorry but it's not like it used to be. Signal to noise ratio is going down the tubes. I would gladly pay to avoid postings of irrelevant people and to read all opinions negative and positive of all kinds of...

Yes, paying is a good idea. Posting should be free, because the posters' contribution is what makes this board so good, so we shouldn't create a disincentive to contribute to the quality of this forum. I am in favor of memberships. to pay to read/post. Memberships not only would...
