Recently, a friend asked me about the most headache-inducing issue in trading—when you should stop loss or take profit. Honestly, this is indeed one of the hardest decisions in trading. Fixed stop-loss points might seem simple, but you often end up running into an awkward situation: the price almost immediately reverses and returns to your stop-loss point, turning what would have been a win into a loss, and you lose for no clear reason.

Actually, there’s a more flexible approach called “trailing take profit” or trailing stop. I’ve used it for so many years, and it really helps solve a lot of problems. Simply put, it automatically adjusts your take-profit and stop-loss levels based on the market price. When the market moves in your favor, the profit keeps climbing, helping you lock in the portion you’ve already earned while also reducing risk.

Let’s give an example. You buy Tesla at $200, expecting it to rise by about 20%. Instead of setting a fixed stop loss at 190, you set “exit if it gives back $10.” When the stock price rises to 237, your stop-loss level automatically adjusts to 227. That way, even if the price later drops back to 227, you can still keep most of your profit. This is the core logic behind trailing take profit.

Why is this method more effective? Because market volatility is the norm, fixed levels often can’t keep up with the market’s pace. And a trailing stop take-profit/stop-loss can automatically adjust according to real-time price changes—expanding your profit potential when the market turns favorable, and also cutting losses in time when the trend reverses. This is especially useful for swing trading.

That said, let’s be clear: trailing take profit is not a cure-all. It works best for assets with a clearly defined trend and continuous volatility. If the market is moving sideways with tight range movement and extremely small swings, or if volatility is too severe, then this method can end up triggering stop losses too frequently, hurting the strategy’s effectiveness. So before using it, you still need to understand the asset’s movement characteristics.

One strategy I often use is ladder-style position adding combined with trailing stops. For example, you buy 1 unit at 11890 points, then add 1 more unit every time it drops by 20 points, for a total of 5 units. Then set an average profit target of 20 points per unit. The benefit is that even if the index only rebounds to 11870, your overall position can still reach the average profit target without having to wait for the highest rebound.

For day trading, I use 5-minute K-line charts instead of daily K-line charts, because you need to exit the same day. The same trailing stop logic applies: for instance, enter at 174.6, set take profit at 3% and stop loss at 1%. When the price breaks through the take-profit level and continues rising, your stop-loss price will automatically move up as well, helping lock in profits more effectively.

Another advanced use is combining it with technical indicators. For example, use the 10-day moving average and the Bollinger Bands to judge the trend, then pair that with trailing take profit. This isn’t based on a single fixed price—instead, it dynamically adjusts based on the indicators each day, which better matches actual price action.

To be honest, automated take-profit and stop-loss tools can definitely reduce a lot of pressure, especially for people who are busy during the day and can’t constantly watch the market. But remember, they’re only auxiliary tools and shouldn’t be relied on completely. Over-reliance can actually weaken your ability to judge the market. The most important thing is still to do your homework, understand the asset you’re trading, and then use tools like trailing take profit flexibly.

In summary, trailing take profit is best used in trades where the direction is clear and swing opportunities are obvious. Whether you’re doing swing trading, short-term day trading, or leveraged trading, this tool can help you ride the trend to expand profits when the market moves in your favor, and stop losses in time when risks emerge. I hope these real-world experiences are helpful to you.
