It will be by the results they have if the person will allow you to see their portfolio of trading or trading history depending the terminology you like to call it, so in there from the first day the first position was open till the very moment you meet them to become your mentor will be seen and you will compare the lost to the wining to make your decision. However we are just saying but I'm not sure if a mentor will allow there client who wants to be taught to already evaluating them of their capabilities of who they said they are and also to expose their total trading funds on the account, so that would be issue on the using results.
