Trading is actually very simple. It's called trading, but it's really just gambling.
Everyone can gamble; the key is where to open positions and where to take profits.
Opening a position is easy. When the major trend is still in place, just buy when it drops. When you judge that a major trend is coming, don't be afraid to chase it even if it means buying at the peak.
Taking profits is very difficult. This requires overcoming one's own nature. Can you accept that after taking profits, it still goes up several times?
You must approach it with the mindset that winning is my destiny, losing is my fortune, and then gamble and operate.
