Trading contracts, the biggest fear is making a profit and then giving it all back. Today I want to share some personal practical experiences.

**Tip 1: Lock in profits once you make money**

When the coin price rises more than 10%, you should start to be cautious. This is a critical point—if it returns to your buy-in price afterward, don’t hesitate, just sell. Don’t be greedy, because often a simple pullback can wipe out your previous gains.

If you’ve gained 20%, set a rule for yourself—at least lock in 10% profit before selling. Of course, if you’re sure this is a local high, then it’s a different story. But most of the time, we’re not experts, so playing it safe is the right choice.

If you’ve gained 30%, similarly, 15% profit should be your bottom line. This approach might seem like you’re not maximizing profits, but in reality, you’re letting your profits compound automatically. Even if you don’t hit the exact high, over the long term, you won’t suffer too much loss.

**Tip 2: Cut losses decisively when losing money**

This is the hardest to do but also the most important. If the coin you bought drops 15%—you can adjust this percentage yourself, but 15% is a reasonable reference—sell immediately, don’t delay.

Some say, “I’ll wait a bit, it will rebound eventually,” but that mindset is dangerous. Once the loss widens, your mentality gets shaky. Setting a stop-loss is like installing a fuse—it helps you prevent the worst-case scenario. If it really rises afterward, it means you entered at the wrong point; accepting some loss is just paying tuition. Remember, every position must have a pre-set stop-loss. This isn’t being timid; it’s professional.

**Tip 3: Rebuy at the original price if the coin you sold drops**

Sometimes, after selling, the coin price pulls back, and if you still believe in the project, buy back the same amount. This way, the total coin amount remains the same, but your cash in the account increases.

Another situation is if the price doesn’t drop much after selling, but then it rises back to your sell price. At this point, you should buy back unconditionally. Although it costs a bit more in fees, it helps avoid missing out. This principle works best when combined with stop-loss rules—if it rises back to your cost, buy back; if it drops further, stop-loss.

After doing this several times, if you find a coin is constantly fluctuating within a certain price range, then change your approach and look for new entry points. Frequent volatility indicates short-term instability of that asset.

**Final words**

Short-term trading emphasizes rhythm; quick in and out is about controlling risk, not reckless gambling. Chasing hot spots requires judgment; don’t just rush in blindly. Taking profits when the time is right is rational, not cowardly. Sitting on the sidelines is also part of a strategy—it doesn’t mean giving up on trading.

Instead of obsessing over the lowest and highest prices, it’s better to develop a trading discipline you can follow. That’s the key to long-term survival.
