This is something that is often talked about, namely about luck in trading. For me, knowledge can invite good luck, without knowledge we cannot even carry out any kind of trading. With the knowledge we have, it will be very helpful and even determine our trading.
I can't force people's views on this, because of course they have their own thoughts about the role of luck in trading. So I'm just giving my view on luck in trading.
I agree with you! Knowledge, patience, and discipline first, luck is totally secondary. Sometimes it does some moves that we like or we don't, but in any case, we shouldn't rely on it.
Well from there we can find out where the position of luck is. For example, I will try to compare it with gambling which is very dependent on luck. In some gambling, we just play, we can't see and predict, even someone who doesn't know gambling when they can play and if they are lucky they will win.
While in trading, we must know what trading is and how to do it, when someone just trades without knowledge then I can say they are gambling.
I understand your position on the trivial answer, "luck" in casinos, but if we are in a forum, where we evaluate ourselves on a certain level of knowledge, that is not a very good position/idea.
When one goes to a casino, if one is a recreational player, all this stuff we say here does not matter, but if you are a regular, you must understand the game, then you understand why poker and BJ allow for a more feasible return away from the thing that everyone calls luck, which in my case I like to call "Dictator", because it exercises the laws of probabilities whenever it feels like it.
So, there are many things that tend to be mixed up in ideas, in this subject, the luck that one has in casinos cannot be compared to commerce, well, as a trivial adjective yes, but from the statistical point of view and how these probabilities are executed it is totally different.
