Really? Why don't you go back to your job of programming in assembly code before you get fired for spending too much time on forums and let questions about trading systems to more qualified individuals?
Do you think there are people in this forum in a sane state of mind who would spend 60K+ for curve-fitted systems? You know, the type you develop...
I had the same opinion for months after using various search algos, that it's all a pipe dream and that products like TSL are scams. I was really down. It took that much time and patience to learn how to use this type of software. There aren't exactly textbooks filled with statistics on various approaches to selecting input/output values, fitness functions, analysis of market dynamics and suitable patterns/indicators, a range of side-ways and WFO out-of-sample testing, etc. You have to try and learn all by yourself. So i don't blame you for thinking that, a lot of people think so too, even some that have had a lot of experience. In the end, my opinion still holds, that once you learn to use it the curve-fitting disappears and you are able to create good looking diversified portfolios that have a low probability of letting you down. You just sound like you don't have experience doing all of the above with search algos, especially given the low quality of commercial applications that are available out there, so it's pretty expected that you would think so. Maybe, a year from now, i might conclude that my current thoughts were just based on luck and that it really cannot work in the long run, but for now, my attitude doesn't change. I could also repeat my posts from before on how machine learning is just a different form of human learning if done properly, but i'm not sure there's much use of repeating myself. I dont like claiming i'm the smartest guy in the world with my "advanced search algos" and stuff when there are people with far more experience here and elsewhere. The reason i'm not listening to experienced traders when they say "its all a curvefit" is because a very small number of them has had enough experience in this area which is still very very new. The few that i've talked to in detail (with negative opinions) have demonstrated a lack of understanding for the subject and a general dislike for all things new and innovative.
Finally, our new member here can maybe tell us if he has live trading experience with TSL developed systems and what his portfolios look like in general terms. That would help the discussion, i'm sure.
On the other hand, i agree with you that it's silly to spend 60k on such software, especially given the above fact - how much time and effort it takes to learn to use it. Also, TSL makes it hard to test a lot of theories quickly for various reasons, but i won't get into that. An informed buyer should be weary.
Oh and, i can fire myself, but i'm not about to quite yet.
So i invite you to not generalise. Just like all my friends think everyone trading the markets is a billionaire, which is not true, it's also not true to think that every search algo or machine learning in general are bad.
