Recently, many people have been losing money in cryptocurrency trading. The main reason is that they haven't clearly understood the meaning of stop-loss, nor have they established a complete take-profit and stop-loss mechanism.

I have to say, take-profit and stop-loss are truly the most important defensive lines in trading. Take-profit means decisively selling when you reach your target profit, and stop-loss simply means cutting losses to prevent losing all your capital. Many people get stuck in their mindset, watching prices rise and wanting to earn more, only to get trapped or stubbornly hold onto losing positions, hoping for a rebound, which ultimately results in greater losses.

From my own experience, once you set up your take-profit and stop-loss, your trading mindset becomes much more stable. Because once the price hits your preset conditions, the system automatically executes the trade for you, completely avoiding human interference. You no longer need to watch the market anxiously or make impulsive decisions based on short-term fluctuations.

How exactly to operate? Suppose you buy a coin at 1000 and want to sell at a 200 profit, so you set the take-profit price at 1200. Conversely, if you can tolerate a maximum loss of 100, you set the stop-loss at 900. But there's a detail: since the current market price is 1000, placing a sell order at 900 will execute immediately. So, you need to use trigger prices to set it up. For example, set the trigger price at 900 and the stop-loss at 890. When the price drops to 900, the system will then place a sell order at 890, preventing an immediate execution.

There's also an advanced method called trailing stop-loss. It’s not fixed at a certain price but moves proportionally. For example, if you set a trailing stop-loss of -200 at 1000, when the price rises to 2000, the stop-loss will automatically move to 1800. This way, when the price pulls back, you can still preserve most of your profits, making it very flexible.

Experienced traders always evaluate the risk-reward ratio in advance to decide whether to enter a trade. For example, a 80% chance to earn 10% versus a 20% chance to lose 30%. Since 80×10 is greater than 20×30, this trade is worth taking. This is the practical application of the stop-loss concept — not to avoid losses at all costs, but to make data-driven decisions.

Mainstream exchanges have built-in take-profit and stop-loss functions, supporting both spot and futures trading. Spot trading is more straightforward: just set trigger prices and execution prices. For futures, you can set them all at once when opening a position. After execution, the system automatically creates take-profit and stop-loss orders, saving you the hassle of manual operation.

Finally, I want to say that the ratio of take-profit to stop-loss has no absolute standard; it depends on how much loss you can tolerate. Some traders refer to support and resistance levels, others look at moving averages, but the core logic is the same: set take-profit where you feel satisfied with your gains, and set stop-loss where the loss would make you feel painful.

In summary, take-profit and stop-loss are about replacing emotions with discipline and intuition with data. Persisting with this system over the long term will help you survive longer in this market.
