Not everyone has an access to this so in a way it's not really a mistake on the newbie trader side, some people just started trading and they just gained their own experience through continuous losses and gains and even if they try and find a school that does this exact thing, they're going to get nothing out of that because the market is volatile and they might not even use a lot of the stuff that they've learned in that school when the actual trading happens, mentors are expensive especially if you don't have a connection.
