Trendlines turn the abstract idea of a trend into a concrete, drawable tool. Used with discipline they frame entries, exits and the moment a trend is breaking.

Drawing a valid trendline

Connect at least two significant swing lows (uptrend) or swing highs (downtrend); a third touch confirms it. The more touches, the more respected the line — but also the more watched, and the more likely to be tested.

Channels

Add a parallel line on the opposite side and you have a channel, framing where price tends to oscillate. Channels help you avoid buying at the top of the range or selling at the bottom.

Trendlines break — that's useful

A clean break of a well-respected trendline is information, not failure. It often signals the trend is pausing or reversing. Trendlines are a guide to structure, not a magic barrier.

Key takeaways

  • Connect 2+ swings; a third touch confirms the line.
  • Channels frame oscillation and stop you chasing extremes.
  • A trendline break is a signal of change, not a tool failure.
