Trendline
Also called: Uptrend line, Downtrend line, Trend line, Trend çizgisi, Yükselen trend çizgisi, Düşen trend çizgisi
A line joining the rising lows of an uptrend or the falling highs of a downtrend; it shows the trend's slope and where pullbacks may end.

What is a trendline for?
A trendline makes a trend's slope visible. In an uptrend you connect the rising lows, in a downtrend the falling highs. The line doesn't do anything by itself; it just shows the rhythm in which price has been pulling back and moving on.
The real information is in the structure, not the line. An uptrend means higher highs (HH) and higher lows (HL). If every pullback ends above the last one, buyers are stepping in earlier each time. The trendline is simply a ruler laid across those lows. A downtrend works the other way round, lower highs and lower lows, and the line across the highs shows where each bounce may meet sellers.
A well-drawn line tells you two things: roughly where the next pullback might end, and when the trend changes its rhythm.
How do you draw a trendline?
In an uptrend, pick two clear swing lows and connect them. Two points make a line but prove nothing yet; if price comes back a third time and reacts, the line is confirmed. In a downtrend, do the same with the highs.
There's no single right answer to wicks versus bodies. Wicks show the extremes price reached, bodies show where closes were accepted. Pick one, use it on every chart, and read the line as a thin zone; a few pips of overshoot doesn't end a trend.
Don't force it. If you have to cut through the middle of candles to make the points fit, the line isn't there. A good trendline is obvious the first time you look at the chart.
For trading, the line alone isn't a reason to enter. When price pulls back into the line and a demand zone at the same time, you want to see buyers react there: lower wicks, closes back up. The stop goes below the last higher low; if price gets there, the HL structure is broken.
Try it on a chart
No trendline is drawn on this chart; what's there is what a trendline stands on, the structure of higher highs and higher lows. Check whether that structure is still intact, where the pullback met a reaction, and which low your stop would sit under.
The uptrend structure is intact; price pulled back and bounced off the demand zone. What do you do?
No sign-up needed. Make your call; when the chart opens you'll see why.
The usual mistake: forgetting structure
Putting the line ahead of structure. Declaring the trend dead because price poked through the line, or trusting the trend because the line held while structure broke, are two faces of the same error. If the last higher low has broken on a close, the uptrend is in question wherever the line sits.
Trusting a steep line. A steep line drawn off a few sharp candles breaks as soon as price goes sideways for a while, because no trend keeps that pace for long. A steep line breaking usually means the trend is slowing, not ending.
Then there's treating a pullback as a threat. If structure is intact, a pullback in an uptrend is a chance to join at a better price. Beginners often buy the top and sell the pullback in fear, trading exactly against the trend's rhythm.
When does a trendline mislead you?
In a sideways market a trendline means nothing. If price is wandering inside a band, you can connect any two lows, but there's no trend behind the line. Timeframe also sets a line's weight: one on the daily chart is on far more screens than one on the five-minute.
Lots of stops gather just under an obvious line that everyone has drawn. Price sometimes wicks below it, takes those stops, and closes back in the trend's direction. Flipping your bias because the line broke, without waiting for the close, is the fastest way into that trap.
Finally, the line looks backwards. It joins past lows and assumes the future keeps the same slope, while real trends speed up, slow down and turn. Update the line as new lows form, and let structure, not the line, make the call.
Frequently asked questions
How many points do you need to draw a trendline?
At least two swing points: two lows in an uptrend, two highs in a downtrend. But two points are only an assumption; the line counts as confirmed when price comes back a third time and reacts. A fourth or fifth touch doesn't make it stronger. If anything it uses up the buyers there and can make a break more likely.
Does a trend end when the trendline breaks?
Not necessarily. A broken line shows the trend losing speed; structure tells you whether it's over. In an uptrend, as long as the last higher low hasn't broken on a close, the trend is technically intact and price can resume after a sideways rest. If price fails to make a new high after the break and then takes out the last low, a reversal becomes a serious possibility.
Should a trendline be drawn from wicks or candle bodies?
Both are used, and both make sense. A line off the wicks shows the extremes price reached; a line off the bodies shows where closes were accepted. Whichever you choose, use the same method on every chart and read the line as a thin zone. A few pips of overshoot isn't a break unless the candle closes beyond the line.
