And something more:
Even "the teacher" is no willing to show you his account claiming does not want to show his money (because of tax problems or kidnappers or whatever ) you can still can ask for:
1. A MyFxBook account where money are not shown but pips are
2. Accounts from his former students...
The story is over and over again, the same.
Some guys asking a lot of money for teaching FX and proving them self with Excel like charts about how profitable they are.
My advice for anyone wanting to buy a course, a signal or a trading room is to ask for a proper certified account statement done...
