Recently, I found that many people tend to fall into a common misconception when trading cryptocurrencies: they make a little profit and then want to wait and see if they can make more, but end up losing everything as the price keeps falling. In fact, this is when take-profit and stop-loss come into play.

Simply put, take-profit and stop-loss are two straightforward concepts: take-profit is deciding when to lock in your gains, and stop-loss is setting a bottom line; once the loss reaches that point, you exit to cut losses. It sounds simple, but implementing them can change your entire trading mindset.

My own experience is that without setting take-profit and stop-loss, watching the candlestick movements causes my mood to fluctuate, making it very easy to make wrong decisions. But once I set the take-profit and stop-loss levels, the system automatically executes them, allowing me to detach from emotional interference. More importantly, by practicing take-profit and stop-loss, you can truly evaluate whether your trading strategy is effective, and over the long term, whether you're making a profit or a loss.

How exactly to set them? Suppose you buy a coin at 1,000 yuan and hope to make 200 yuan profit, then set the take-profit price at 1,200. Conversely, if you can only tolerate a maximum loss of 100 yuan, set the stop-loss at 900. But here’s a trick: placing a sell order directly at 900 will execute immediately because the current price is still 1,000. Instead, you should set a trigger price—when the price drops to 900, the system will automatically place a sell order at 890.

There’s also an advanced method called trailing take-profit and stop-loss, which uses relative ratios instead of fixed prices. For example, setting a trailing stop-loss of -200 means if the price rises to 2,000, the stop-loss becomes 1,800. When the price pulls back, you can still earn 800. This concept is like adjusting your protective range as the price moves, avoiding being limited by rigid numbers.

Many trading platforms have built-in take-profit and stop-loss functions. When placing an order, you can set them simultaneously, saving the trouble of manual adjustments later. Experienced investors often calculate their risk-reward ratio beforehand—for example, a 80% chance to earn 10%, and a 20% chance to lose 30%. Since 80×10 > 20×30, it’s worth entering the trade. This quantitative thinking combined with take-profit and stop-loss is key to stable profits.

Honestly, the main role of take-profit and stop-loss is risk management. They ensure you don’t see your original gains evaporate, nor do you hold on endlessly out of greed until liquidation. Everyone’s acceptable profit and loss levels are different. My advice is to set take-profit at a point where you feel satisfied with your gains, and stop-loss at a point where the loss would make you feel distressed.

In the long run, consistently applying take-profit and stop-loss not only protects your capital but also helps you find truly effective trading strategies. Those seemingly missed gains are actually protections for your existing profits—that’s the mindset of a professional trader.
