Recently, I was chatting with friends in the industry, and he shared some data: an initial capital of 100,000 grew to 20 million in three years. My first reaction was not envy, but regret—why didn't I have a firmer resolve to delve into trading logic back then? This guy initially couldn't even understand candlestick charts, and now he has become the person many people privately seek advice from. The key is that his success weapon is actually very "ordinary"—it's the fundamental logic that looks so simple no one believes in it.
