A few basic understandings:

1. Can you make big money by relying on technology? No, it's about the market, or rather, about the big trends, along with a trading system that can set clear goals, maintain a good mindset, and firmly execute rules during the fluctuations of these big trends.

2. The larger the market trend, the less it relates to technology, and the greater the tolerance for operational errors. The money earned is like a windfall, but the requirements for mindset are higher; as long as you avoid greed, it’s just a matter of making more or less.

3. The smaller the market trend, the higher the technical requirements, the smaller the tolerance for operational errors, and the higher the trading costs, making it more difficult to make money. Volatile periods are the easiest times for erratic operations.

4. Trading profit-loss ratio, trading win rate, and trading frequency; you can choose at most two of the three.

5. The core of trading is not how many trades you got right, but how much you grasp this particular trade. Leverage is used to amplify profits; if you don’t have a good grasp, don’t use it.
