#美国核心物价涨幅不及市场预估 The most heartbreaking lesson in trading contracts:

You have to think the other way around — set your loss limit first, then consider how to make money. Many people do it the wrong way.

In the short-term contract game, it seems to be about selecting coins and judging trends, but actually it boils down to two things: discipline in stop-loss and emotional stability. Win rate doesn't need to be very high; even 60% can be very comfortable as long as each loss is within the plan. The problem is that most people can't withstand days of consecutive losses; when emotions collapse, they start recklessly adding positions. One out-of-control order can wipe out three months of profits.

That's why some traders double their accounts annually, while others keep getting liquidated repeatedly. Good technical skills are actually secondary; the real test is whether you can mechanically execute stop-loss orders when your account is in the red and signals are chaotic. This is more difficult than any technical analysis.
