Many people lose money trading contracts, but it's not because they see the wrong direction; it's because their trading logic is a mess. Today, I want to discuss three trading principles that can truly help you survive.

**The Art of Taking Profits**

When the price increases by more than 10%, be prepared to act—take profits decisively when it falls back to the cost basis. If it reaches 20%, don’t be greedy; set a safety line at 10% profit and exit. When the gain hits 30%, at least secure 15% profit before considering selling. The benefit of this approach is that you don’t have to gamble on the peak every time; profits will accumulate naturally.

**The Bottom Line for Stop-Loss**

Set a 15% stop-loss level (adjustable based on your risk tolerance), and cut immediately if it drops below. I know this can be uncomfortable, but it’s not about giving up; it’s about protecting your principal and having a chance to turn things around. Those who don’t set stop-losses will eventually be wiped out by a market move. This is the most basic requirement for opening a position.

**Remedies After a Sudden Drop**

If you sell a coin you believe in and the price drops afterward, it’s okay—buy back the same amount. You haven’t lost the coins and can profit from the price difference. Even if there’s no significant retracement, buying back when it returns to your sell price is worthwhile—the trading fees are minor, but missing out on a move is the real big risk.

Short-term trading is never about luck; it’s about execution. Enter and exit quickly, take profits when the time is right, and holding cash is also a strategy. These seemingly simple principles, if adhered to, can help you establish a foothold in the crypto world.
