After finishing the previous main text, I thought about my conversation with my former supervisor, which greatly influenced my view on short-term trading.
I am a conservative person who only likes long-term trading. People around me have lost all their assets playing stocks, so I always have a piece in my heart that doesn't understand why so many people take risks to do short-term trading.
Many of my former colleagues liked to do short-term trading. One day I asked my supervisor, why do you all love short-term trading so much?
"Because we are poor, we have to fight for turnover rate, that's the only way to have high capital efficiency"
I think this reason is sufficient.
It's not because of greed, nor the gambling nature, it's just because I know that my supervisor has really been poor, and just wants to live a slightly better life, which is why he chose the short-term market. The person I saw was already middle-aged, but he succeeded through short-term trading. I also agree with him.
