This is the reason why most of the newbie traders losses a lot of money in trading, because of this kind of perception.
A certain strategy won't make you profitable in a very short period of time, it takes years to polish, and if you don't have the patient and discipline, I can say your funds will always gonna wiped out. And about the winning percentage, I can say that don't focus on it too much, what's important is your PnL.
No, he didn't say that trading is easy but he forget to realize that 7 months of experience is already a lot. And you said you only start futures trading on March 28. We don't know what if you also/already have a long experience on doing normal trades or in spot trading? So that shouldn't surprised us anymore on why you are now doing well.
I think patience and discipline are not far from each other and then apart from them, there might still be others that are also needed. It's crazy that there are still people who continue even if they lack on it.
I think it was their greed or temptation that gets them. They aren't even contented that even if they already fail, they repeat the same sh*t again. Oh well, they already treated trading like a gambling even before because they only rely on their luck, so why not?
The same thing why gamblers keeps on coming back in the gambling field. They think that one day, they will hit it but they did not realize the losses that they incurred before getting it. What they are doing is not worth it and does not make any sense. If we have a good PnL ratio in trading, then that means we are doing better and so as our winning percentage.
