You could watch someone compete/perform at a very high level on TV, but seeing how it's done does not make you successful.
But perhaps what you see is what won't work. Its all about watching good habits be executed over and over. Imagine wanting to play tennis, and you think you're doing good because you know how to hit the ball, but for some reason you never win matches. Then after watching a pro play, you learn that they not only hit the ball, but they have to always run towards the ball because the other player hardly ever hits the ball back to where you are. It might sound stupid since we all know how tennis works, but watching just this one profound change can make all the difference to your game. Everyone might say just hit the ball, and you're already hitting it when it comes to you, but nobody ever says how aggressively you have to run after it as well.
So, I have to strongly disagree that mentoring someone is ridiculously easy. Showing someone how to trade successfully may be, but that's not the same thing.
I'm just honestly so sick of people saying they will help other traders work on their own method. Fuck, each one of us that have been here for years can help someone else. All we do is look at their stats, look at their trades, see where the losses are, and magically come up with a set of rules that would turn those losses into wins. Then we sound so smart! We can throw out catches phrases like "here you chased the price, and now your stop had to be too big", which is always obvious after you know what happened. Or "here you used a tight stop when you're clearly trading in chop", which is once again only ever apparent in hindsight. It all sounds brilliant when someone wants to mentor you because they have the advantage of stating the obvious after the fact.
If I was to ever have a mentor, I would say let me watch you trade for one week so I get a feel for your trading style and stats. Then for the second week let me follow your trades. If of course I find that I can't even blindly follow a winning trader and match his performance, then its a big clue about where the problem is. Third week I would want to start anticipating the setups and make suggestions in advance to see if he would agree. Like here comes a double bottom and it looks oversold, do you think a long here would work? Its not about him teaching me anything, its about me asking questions and picking his brain. I don't expect him to have a curriculum planned.
He probably doesn't even know how to teach, as is the case with most professions. To be an excellent teacher is an even higher skill than to excel at that activity, assuming of course that you excel at said activity. To do it well and be able to teach it is extraordinary. So why are we looking for such a person? There really are only three combinations.
1. You're not really that good at trading, but you've studied so much and do such great analysis that you probably have lots of great insight to share. And since you're never making live calls or can prove you're trading, its easy to demonstrate how vast your trading knowledge is. This is where most people fall into.
2. You're a great trader, but can't quite explain how you do what you do. You get hunches, based on tons of screen time, but its not something that you can really put down on paper, and obviously don't even care to. You have your rules, but know how to break them because each day really is different. So you're willing to take the risk to put on an aggressive trade because you understand why you did it and how you will manage it. You simply journal for yourself, or maybe not even anymore as what you're doing is essentially the same day after day, and so your main focus is on proper execution and counting your profits. This is the type of guy who would make a great mentor of the type I am describing.
3. This guy is not only an excellent trader, but an excellent teacher. He has a way of making concepts easy to understand, but most importantly, can asses where the student is lacking. Its like if you're teaching another language and the dumb teacher would just get students to repeat works after them hoping they catch onto the accent. The excellent teacher would understand that for some languages, tongue position is of utmost importance, and yet in other languages, sounds don't come from exact positions of the tongue. The teacher would know that even before we practice the sounds, we first need to make sure the tongue is in the right place of the mouth. This type of ability, to not only perhaps the task with a high degree of proficiency, but also identify where others are failing at it is truly unique.
With regards to trading, this teacher, as an example, would be able to assess that the student cannot process information as quickly as others, so its critical for this student to develop more of a swing trading strategy vs. having to make decisions in seconds. Or perhaps another student is extremely fearful of losses, so its perhaps best to look for a strategy without long hold times, focusing on high win rate vs. a strategy with huge wins, but lots of little losses along the way.
So this type of teacher is not only just showing a student how they make money, but able to asses the failings of the student with regards to their own trading, and put them back on the road of the path that they are on. Its like they are the world's best coder and can not only code themselves, but fix other people's coding deficiencies, which I hear is extremely difficult to do if you are tasked with fixing the bugs in what someone else wrote without the luxury of starting from scratch and just doing it how you would want to.
Clearly finding a teacher like this is an impossible endeavor. But striving to find someone in the second category is I think vastly superior to picking up someone from the first. We have tons of people here at ET who fall into category 1. Category 3 we can all just forget about.
