How many people have you seen make half a profit in a contract and then give it all back? Or even lose their principal?

I've seen too many. Most of the time, it's not about misjudging the direction, but simply lacking discipline.

No matter how accurate the technical analysis is, without discipline, it's all useless. Some veterans survive to this day by sticking to these three principles:

**First Trick: Take Profits in Batches**

Don’t expect to ride the entire wave. When the market rises by 10%, be alert. When it hits 20%, lock in half of your position immediately. When it reaches 30%, secure the remaining profits. Honestly, people who live by discipline tend to last longer than those gambling on gut feelings.

**Second Trick: Be Decisive with Losses**

A promising position drops 15% and doesn’t rebound? Don’t wait, don’t hesitate—cut it immediately. Some people regret it afterward—what if it rebounds? But this mindset is the root of doubling losses. No stop-loss means pure gambling, plain and simple.

**Third Trick: Re-enter at Low Points for Greater Gains**

If the price continues to fall after you sell, buy back at the original price. Keep your position structure unchanged, but make your cash flow more efficient. Missed the early rise? As long as it’s still in an upward channel, keep adding without overthinking. Transaction costs are negligible compared to potential gains.

Final words: Don’t chase hot spots blindly in short-term trading, and don’t follow trends blindly either. Those who truly make money share one trait—knowing when to sell. Stick to discipline and control your pace; that’s the secret to surviving the volatility market the longest.
