Well put, you've hit the nail on the head. I started my trading journey by signing up with a trainer. While I have no doubt about his sincerity, after a year of training under him, I began to observe that his technical system was flawed. It had to do with MA cross-overs and other indicators. When questioned about it by students, he would get a little riled up and give many reasons for why their trades failed.
You have to bear in mind that some of his students were engineers who could design and build a petroleum refinery from scratch, much less read a chart. The sad thing is that there were also less analytical folk, moms and pops that would basically have to rely solely in his guidance in this unforgiving industry.
I picked up mql4 and after a while, coded his system. It did not work. I spent another 3 weeks refining the code, trying to improve the entries/exits, built filters, etc... and got the win-loss ratio to 1:1. After that I was pretty much disillusioned.
I went back to his gatherings to see what I might have missed. Then I realised that he would always be describing entry setups using historical periods, where it is patently obvious that an entry condition was fulfilled. This is flawed because you can find as many scenarios where the same setup fails. And you must always test your system at the leading edge of the market, not on a historical period.
When questioned about the failed setups, he would go into defence mode and brush you off with a witty quip. Tragic thing is that I truly believe he is not a fraud, but that he could not see the flaws in his own system.
His system delivered no edge.
I reckon this also applies to what PipGnostic is saying, that if you get a mentor that leads you down the wrong path, you waste a lot of time and money.
I suppose also if Ezekiel did not sign off with 'Asia #1 Forex Mentor', he would just be expressing an opinion rather than implying he teaches this stuff to his mentorees. His post on the Oanda forum is also just positive psychology on taking affirmative action, I don't see the scam angle. The WSO marketing stuff is a little strange though. Granted, with the little that is known, I don't think he is qualified to teach, but let's give him the benefit of the doubt and let him prove himself.
