Ascending Triangle pattern
An ascending triangle has a flat upper boundary and a rising lower trendline. Buyers keep stepping in at higher prices while sellers defend the same ceiling, compressing price until one side gives way.
How to identify a ascending triangle
- At least two highs at roughly the same level forming horizontal resistance.
- At least two higher lows that can be joined by a rising trendline.
- Price range narrowing as the two lines converge.
What confirms it
A close above the flat resistance line. A retest of that line from above that holds is a second confirmation.
What invalidates it
A close below the rising trendline breaks the structure of higher lows.
How traders project a target
Measure the height of the triangle at its widest point and add it to the breakout level.
Common mistakes
- Assuming it must break upward. Ascending triangles can and do break down.
- Entering in the middle of the triangle where the risk is poorly defined.
- Waiting so long that the breakout happens at the apex, where moves are often weaker.
Where it appears
Often appears as a pause within an uptrend. It can also form at the bottom of a downtrend as a reversal.
Frequently asked questions
Is an ascending triangle always bullish?
It has a bullish bias because buyers are making higher lows, but it is not guaranteed. A close below the rising trendline invalidates the bullish read.
How many touches does an ascending triangle need?
Two touches of each line is the minimum to draw it. More touches make the lines more credible.
What is a false breakout?
A move above resistance that quickly closes back inside the triangle. It is one reason many traders wait for a candle close or a retest.
