Yesterday, I liked watching people in the group talk about trend lines, and someone asked if they really help. So I want to share my own opinion about this tool.

Trend lines are like glasses that help us see the direction of price movement more clearly. It’s nothing complicated—just draw a line connecting at least 3 swing points of the price. Then, you get a line that tells you whether the market is in an uptrend, downtrend, or sideways.

What I like about trend lines is that they tell us many things. For example, if the line slopes upward from left to right, it indicates that the price is rising, and this line can serve as a strong support. Conversely, if it slopes downward, the price is falling, and the line acts as resistance. Moreover, we can use the slope of the line to predict how much the price might move in the next period.

When it comes to actual trading, I often use trend lines with a swing trading strategy like this: First, observe where the price changes direction, which can be seen from price patterns or breakouts. Next, draw a line connecting at least 3 swing points. The more points, the stronger the line. Then, watch whether the price continues to follow the line. If it does, we can enter trades in the direction of the trend.

But be cautious: when the price starts to break out of the trend line, it’s a warning that the trend might change. The first breakout might not be a true breakout. I’ve been fooled many times. Therefore, always set stop-loss points beforehand.

One strategy I like is waiting for the price to break out of the trend line and then retest it. If the line can no longer hold, the price will move in a new direction. That’s when we can enter a trade. Another strategy is waiting for the price to squeeze close to the trend line in formations like flags or triangles, then trading based on the price rebound.

But don’t forget that false breakouts can happen anytime. Sometimes the price breaks out but then returns to the original trend. The best way to reduce risk is to look at trading volume. If the breakout occurs with high volume, it’s stronger. Also, there should be a retest of the old support or resistance before a new trend begins.

In summary, trend lines are simple and really useful tools. But they are not the only way to become profitable. They should be combined with good risk management, setting stop-loss points, and confirming with other tools. Anyone interested can try using them—practice with virtual money before trading live. It will help you better understand how this tool works.
