#美国核心物价涨幅不及市场预估 The most common pitfall in contracts is taking win rate as a report card.

I've met quite a few people—including myself in the past—who end the month with losses despite an 80% win rate. Why? Because when they’re winning, they only aim for 5% profit; when losing, they stubbornly hold onto 50% of their positions. Winning ten times doesn’t make up for one big loss.

The root cause, frankly, is human nature. When profitable, they’re afraid of profits evaporating and want to lock in gains immediately; when losing, they hold onto hope, fantasizing that a market rebound will save them. And the market is best at exploiting this contradictory psychology.

Turning the situation around relies on changing your thinking: from "Did I win more often?" to "Is my profit-to-loss ratio correct?"

My approach is very straightforward—any trade must have a potential reward at least twice the potential loss (profit-loss ratio ≥ 2:1), otherwise, I don’t take it.

How to implement this? Three tips:

**Calculate before acting.** Set your stop-loss and target levels in advance; your profit potential must be at least twice your risk. If this condition isn’t met, don’t enter.

**Use tools to constrain yourself.** Don’t rely solely on willpower to hold positions during trading; use automatic take-profit and stop-loss orders to execute your plan. Emotions are just noise once you’re in the market.

**Continuously review and record.** Keep track of the actual profit-loss ratio for each trade, and review at the end of the month. Identify where your entry and exit logic failed, and adjust your strategy for the next cycle.

The essence of trading is actually very simple: it’s not about how many times you’re right, but how much you earn when right and how much you lose when wrong. Use discipline to cut losses and let profits grow freely in favorable situations. This is the fundamental logic for surviving long in the market.
