What a trendline is
A trendline is one of the simplest tools on a chart. It is a straight line drawn along the dips of a rising market or along the peaks of a falling market. The line gives you a quick read on direction and on how steep the move is. It also marks a place where price has repeatedly paused.
How to draw a trendline
- Find the trend. Check the market structure first. Draw upward lines in an uptrend and downward lines in a downtrend.
- Pick two clear points. In an uptrend use two swing lows. In a downtrend use two swing highs.
- Connect the wicks. Anchor the line to the tips of the candles. The wick shows where price actually reached.
- Extend it to the right. The line now shows where price may react next.
- Check for a third touch. A third point that lands on the line confirms it.
Two points can always make a line. A line only starts to mean something when later price respects it.
Why more touches matter
Each time price reaches the line and reacts the line gains weight. More traders see it and more orders gather near it. A line with four touches is stronger than a line with two. Strength is not a promise. Any line can fail on the next test.
Reading the slope
A steep trendline shows a fast move. Fast moves are harder to sustain and a break of a steep line says less than a break of a gentle one. A moderate slope that has held for a long time usually carries more meaning. If price keeps steepening and you need to redraw the line again and again that is a clue the move is stretched.
What a break means
A close beyond the line means the pace of the trend has changed. It does not always mean the trend is over. Price may slow into a range or retest the line from the other side or snap back. Treat the break as information. Check whether structure also broke before you act. A break of both the line and the last swing point is a stronger sign than a break of the line alone.
Trendlines and channels
Draw a second line parallel to the first on the opposite side of price and you have a price channel. If the two lines run toward each other you have a wedge. Both patterns start with the same simple trendline.
Common mistakes
- Forcing the line. If you have to ignore half the candles to make it fit then it is not a good line.
- Redrawing it after every break. Move the line only when you have a clear reason.
- Using bodies on one point and wicks on another. Pick one method and stay consistent.
- Trading the line alone. Add another reason such as a level or the bigger trend. See confluence.
Frequently asked questions
How many points do you need for a trendline?
Two points make a line. A third point that touches it confirms the line. Many traders ignore a line until it has at least three touches.
Should a trendline touch wicks or candle bodies?
Either method works if you stay consistent. Wicks show the full reach of price and are the more common choice. Use the same method on every line.
Does a broken trendline mean the trend is over?
Not always. It means the pace changed. Check whether market structure also broke before you decide what has changed.
