Triangle Patterns (Compression Before a Move)
A triangle forms when price makes smaller and smaller swings, squeezing into a tighter range. Buyers and sellers are getting closer to a decision point. Eventually, one side wins, price breaks out, and a strong move often follows.

A triangle is compression. Let the market decide which way it breaks.
Three types of triangles
Ascending triangle:
- The top is flat (resistance stays at the same level) while the bottoms keep rising (higher lows).
- This suggests buyers are getting more aggressive. They are willing to buy at higher and higher prices.
- Usually breaks upward, but not always. Never assume the direction before the breakout.
- Most reliable when it forms during an uptrend as a continuation pattern.
Descending triangle:
- The bottom is flat (support stays at the same level) while the tops keep falling (lower highs).
- This suggests sellers are getting more aggressive. Each bounce is weaker.
- Usually breaks downward, but not always. Wait for the actual breakout.
- Most reliable when it forms during a downtrend as a continuation pattern.
Symmetrical triangle:
- Both the highs and the lows are moving toward each other. Lower highs AND higher lows.
- There is no clear bias. Buyers and sellers are equally matched.
- Can break either way. This is the hardest type to predict, so patience is essential.
- The breakout direction often follows the existing trend, but you must wait for confirmation.
How to trade triangles (step by step)
- Identify the triangle by connecting at least two swing highs and two swing lows with trendlines.
- Wait for a clear breakout beyond one of the trendlines. Do not guess which way it will break.
- Enter after the breakout candle closes outside the triangle. A strong close is more reliable than a wick.
- Place your stop loss on the other side of the triangle or beyond the last swing inside.
- Measure the widest part of the triangle (the base) and project that distance from the breakout point. This is your target.
When triangles work best
- When they form during a clear trend as a continuation pattern.
- When the breakout has strong momentum: a large candle closing well beyond the trendline.
- When the triangle is compact. Smaller triangles tend to produce cleaner breakouts.
- When the breakout aligns with the direction of support/resistance and market structure.
When triangles fail
- In choppy, directionless markets with no trend to support the breakout.
- When the breakout is weak and price re-enters the triangle immediately (fakeout).
- When the triangle is too big and takes too long to form.
- When there is major news that causes unpredictable volatility during the breakout.
Common mistakes with triangles
- Guessing which way the triangle will break. Always wait for confirmation.
- Trading inside the triangle. The moves are small and unpredictable.
- Ignoring the trend context. An ascending triangle in a downtrend is less reliable.
- Using triangles on very short timeframes where noise creates false patterns.
- Forcing a triangle onto a chart where it does not really exist. If you have to stretch the trendlines, it is not a triangle.
