Trendlines and channels
Connect the swing lows to measure a trend and spot when it weakens.
What it is
A trendline connects at least two swing lows in an uptrend (or highs in a downtrend). A parallel line through the opposite swings forms a channel. Price often bounces along the line until it eventually breaks.
A close through a well-tested trendline is an early warning, not a signal to reverse: combine it with a structure break or a retest from below.
How to use it
- Draw the line through clear swing points, not through wicks randomly.
- Use the line as a pullback entry zone in the trend.
- Place the stop just beyond the line.
- Treat a confirmed break plus a failed retest as a reason to stop trading with the trend.
A trendline is a guide, a close through it is a clue.
Common mistakes
- Redrawing the line after every candle to make it fit.
- Using very steep lines that always break.
- Trading the break without waiting for a close.
