My supposition has always been that if you are really good at trading, then there is no need to sell your system. There is no need to put up with those headaches if you are already an excellent trader.
I've always asked, "How many people does anyone know that has bought a system from a vendor, put it in use, and is still a successful trader?" Hardly, without an exception, ones that sell a system do not know how to trade themselves, but they are good salesman. So good-intentioned people are duped into paying for those services.
If someone is a scammer, then there will be inconsistencies in what they do and what they say. There will also be contradictions. I think the thing to do in order to expose them as frauds (provided that is the case) is to confront them one-on-one with facts as it pertains to their fradulent behavior. As an example, I knew Hustlerscreed (Just the name says a lot.) was a king-size fraud, and so I just presented facts over and over to him with regards to all his lies. It has been quite awhile since he has been on this site. Plain and simple, he got exposed. Thus, embarassed.
I didn't read every post in this thread, however, I read a good amount. I don't know anything about fradualent activity with regards to DT ( Did I get the acronym right?). If his activites are fradulent, he will not come to this thread to defend himself. He will hope it all goes away, and everything goes hush. The object is to confront him personally. My supposition is also confront him with facts only--not opinion.
I'm all for having a wholesome site to have good dialogue. I'm also in favor of seeing any fraud fully exposed and ran down the road. I believe LordF has accomplished one thing in getting this thread started, and that is to start dialogues, and possibly make newbies aware of fradulent activity. However, there needs to more offense if they are sent packing.
BTW, if that is not the object, then I stand corrected. I believed that was the ultimate intent, which is the reason for my specific comments.
It may be cynical, but why should somebody sell their profitable system. Most likely they would sell you an obsolete system and teach you some basic staff you can find for free. In that case their charges could be justified as they make it easier for lazy traders who can't be bothered to do a bit of research. With some clever marketing (playing on greed) they are winners.
And then there are failed traders who know a bit about trading, but not quite enough to make profit on consistent bases. So they may see an opportunity in making money by 'educating' general public how trading should be done. They can't spend that much on advertising, so they need help from the forum. And some of them are quite successful (not as traders, but more like entrepreneurs).
