I understand the keen interest towards these because I have been part of a few as well and found out it was bad and left myself but the best educator is actually doing something and realizing why it is bad rather than just hearing about why it is bad from other people.
Realizing how bad they are will make you appreciate that slow growth and process in trading is still the best. You're the one to realize and see the huge gap that it brings if you're learning on your own through your experience, no dictation, no one gives you that doubt to yourself.
We can talk about how that is bad as long as we want and in the end we are going to end up with a big loss no matter what, hence it is not going to be acceptable for OP or anyone who wants to try it out to just hear it from us. Just go join one, and see why we disliked it, but at the very least make sure that you do not spend all of your money on what you hear there so you won't have to start from scratch.
Well for me, they better listen instead of doing the whole thing and joining these so called trading groups. What's must better to be realized is all about learning on their own through trading and understanding it through their made experiences.
