Simulating fills is super-important, are you kidding? In most cases it's enough to count a limit order filled if the price traded above/below it (not at it). I don't see any flaw in such thinking. And of course, directional trading always pays the spread, who else would do it. Models for...

I see what you mean, and i may be misinformed but i'm not sure how the order book would significantly impact trades (eg limit orders only) of an average duration at 1 hour and more on the top 20% most liquid markets (assuming we are allowed to make such a selection). In addition, those problems...

Umm actually, I "think" but I'm not really sure, that certain types of engineers working in medical imaging require working with very large data sets and an ability to analyze them. They also require a high level of knowledge in math an physics (not the technicians that operate machines, the...

Ok, thanks for a approachingly civil response, but i'm still expecting some reasoning that could rebuke my claim in my earlier post to you regarding the theory i mentioned. If you missed the post, go back and read all of it, you'll see i actually agree with you, but there's a "but" in it, and...

Did you not even read my reply to you? You're just calling this guy out on "office views" but when i give you some meat to discuss, you ignore it? Bravo.

Ugh... Reading something like this makes me cringe. You obviously have no idea what "genetic programming" is. It's just a very efficient "search algo", there's no difference in the fact that it's still a "search algo". If they used hill climbing or some older kind of selection algo, it would...

Having a quick look at some job postings from the past 10 days here: http://jobs.phds.org/machine-learning-jobs/quantitative-finance it seems even Goldman Sachs is looking for machine learning experts. Why else would all of them put "Machine Learning Jobs" as one of the tags in the job...

Look i just know, i can't share that info since it's private (not just the email), but trust me he's real. I was the first person who thought he was bogus, he's not.

That right there would be my answer to you. To not re-post my earlier posts i'll say i agree that TSL is being marketed to newbies and that some poor souls end up with a product they don't know how to use - because they lack the knowledge of statistics and a lot of other skills. However, with...

I'm glad someone has finally told me, and with such good arguments, after me posting dozens of posts explaining my opinions and findings. Thanks for that! ; )

My wild guess is he was referring to "Adaptrade builder". You'd have to have a very robust backtesting method for making any of those strats work though, as the fills can often be (as is usual with any advertised strat) unrealistic with such software. It would also take a significant amount of...

You see a website designed as a huge advert, run like hell. Not to mention that in their FAQ they have a Q:"What are futures?" ... lulz... They say they have a hypothetical track record but i'm betting you that if you look at all the Sells they will be on the High of a bar, and all the Buys...

You probably didn't read the whole article. The states of atoms can be entangled but that (the state) is used only for replicating encryption keys which are used for decrypting data sent by conventional means. On the other hand, entaglment can be used for faster than light communication by...

lulz... I was often wondering how many trading desks and "startups" used hackers to get code for successful systems. Since it's "not a crime" why don't we all do it?

I think the reasoning behind selling these machine learning kits is that they are able to create a very wide array of results, since they originate from a random and narrow down to something meaningful with the search process. This means that even if the seller of the software is using it for...

You can scroll down when you click on Forums. It works for me, though, I understand if it doesn't work for a person that refreshes the ET page every 10 minutes, all day, every day. :p Having a 37 items long drop-down menu might also not be practical.

Besides a router with a stronger signal or an improved receiver with your laptop, you might also want to configure the router to broadcast on a wider band of channels. This sometimes helps if there are other WiFis in the area which cause interference.

Not really. Say for example that the comission is 0.03 %. Any spread that is less than that isn't worth it. If you went from lower to higher priced instruments, you'd see the spread is around that value, in my example 0.03%. This in essence means that the size of the spread we get on the markets...

That's because of the spread. If the bid/ask is 1 tick, which is 0.01, for the $20 stock that is a 0.05% per round trip. For the $500 that is 0.002%, and this may not be enough to pay for costs. Obviously, for $500 stocks, the spread is never 1 tick wide due to HFTs, but some larger value like i...

You're very welcome. No, I just researched the subject out of curiosity. Like someone here already said, the barrier to entry for this kind of business is very steep. On the other hand, for a smaller operation, it's possible with lower volume stocks where the bigger HFT firms aren't...
