Trendlines are useful when they summarize repeated behavior. They are dangerous when they become decoration. A good trendline connects reactions that other traders can also see, then helps you judge whether pullbacks are still normal or the trend is changing.
Two touches create the line, three confirm it
Price chart overlaid with a slow simple moving average (SMA) and a fast exponential moving average (EMA), showing the EMA reacting to price sooner than the SMA.
One touch is just a point. Two touches let you draw a candidate line. A third reaction shows the market has noticed the slope. After that, the line becomes useful for planning pullbacks, not for predicting the future with certainty.
Draw through noise, respect closes
Wicks often pierce good trendlines. That does not automatically break the trend. Watch where candles close and whether the next candle accepts price beyond the line. Acceptance matters more than one dramatic wick.
A break needs follow-through
A trendline break becomes meaningful when price makes a lower high after an uptrend break or a higher low after a downtrend break. The line break is the warning; the structure shift is the evidence.
