in fact the coach cannot do anything if students do not give one hundred percent effort. there are many quality resources on the internet on a forex basis and in my opinion the internet is the main forex teacher! if a trader really wants to learn then he can get every facility from the internet. but the big problem of sadness is that most beginners fail! the reason behind their failure is the lack of concentration on forex studies and greed. so I think to be successful it is not mandatory to get a forex teacher, what we need is self motivation. and It's really hard to find a good forex trainer but traders can use the forum as a coach and can take advantage of the presence of other experienced traders in the forum and can use their posts as lessons to learn trading the right way.
