Actually, if one knows how to test, it needn't take more than a few weeks, particularly with replay.
Are you saying one can learn to trade in a few weeks?
You lost a ton of money on a "mentor" who didn't know what he was doing. Your take-away from this has been to demand that anyone who claims any sort of success produce "proof" of his claims. But this is appropriate only if you're looking for someone else to follow. Your take-away should have been that the only reliable teacher is the market, at which point you would have spent your time studying it. Instead, you've chosen to waste time wallowing in victimhood.
No, here you're wrong.
I didn't lose a ton of money because of that mentor. I deviated from his path before that. But when I got in touch with him I was clueless and since this guy seemed to REALLY know what he was talking about and his only "occupation" at the moment was as a trader, I trusted in him and that he knew what he was talking about.
What I wasted was the money I spent on useless books and the time I spent on useless studies. It wasn't completely useless though, since that's part of life and learning.
I'm not wallowing in victomhood at all and I take full responsibility for my own losses.
The point is that I would respect you and others a lot more if you were honest about your results or lack of results if that's the case.
