Pattern 4 of 18: all patterns
Ascending triangle
A flat line of highs above a rising line of lows. Sellers defend the same price while buyers step in higher each time. The textbook expects a break up through the flat top.
The rising lows show demand getting more eager. The flat top shows supply at one price. When that supply runs out, price can move quickly through the level.
- At least four swings: two highs and two lows. Every swing touches its line within a third of an ATR and every close in between stays inside.
- The upper line moves less than 0.6 ATR across the pattern (flat). The lower line rises by at least 0.6 ATR.
- The scanner arms both breaks. A break down is reported too and labelled "against the textbook".
How the alerts work for this pattern
- 1Forming
Four swings fit the two lines. The scanner draws them and watches both sides.
- 2Complete
A fifth swing still fits. The lines are updated as more swings arrive.
- 3Close to signaling
A close comes within a third of an ATR of either line.
- 4Time to act
A candle closes beyond a line.
- xCancelled
The lines meet (the apex) or one more pattern length passes without a break.
The textbook trade
- Trigger
- A close beyond either line.
- Stop
- Beyond the last swing on the other side.
- Target
- The height of the triangle at its start, projected from the break.
Things to watch
- Breaks that happen very close to the apex tend to have less room to run. The scanner cancels the setup when the lines meet.
- The label tells you whether the break went the textbook way. In real markets a good share of triangles break the other way, which is why both sides are watched.
Triangles appear in Schabacker (1932) and in Edwards and Magee's Technical Analysis of Stock Trends (1948), which describes the ascending triangle as usually bullish. John J. Murphy covers all three triangle types in Technical Analysis of the Financial Markets (1999).
