Ascending Triangle

A bullish continuation pattern with a flat upper resistance line and a rising lower trendline, indicating accumulation and building pressure for an upside breakout.

The ascending triangle is one of the most reliable continuation patterns in technical analysis. It forms when price makes a series of higher lows (rising trendline) while repeatedly testing the same horizontal resistance level (flat trendline). Each pullback is shallower than the last, indicating that buyers are becoming more aggressive and sellers are being absorbed at the resistance level.

The pattern represents a battle between buyers and sellers at a key resistance level. The rising lower trendline shows buyers are stepping in earlier each time — they don't want to wait for as big a pullback as before. Eventually, buying pressure overwhelms the supply at the resistance level and price breaks out above it, often rapidly. The conventional target is the height of the triangle measured from the flat top and projected upward from the breakout point.

Volume typically contracts during the pattern's development and expands significantly on the breakout — a confirming signal of genuine demand. Ascending triangles can also appear at market tops (particularly when forming within an existing downtrend), in which case they are more likely to break down than up. Context within the broader trend is essential for correctly interpreting the pattern's likely resolution.

The ascending triangle is often confused with the rising wedge because both show price making higher lows while pushing toward elevated resistance. The difference is decisive: the ascending triangle has a flat, horizontal upper trendline — a specific price level where sellers have repeatedly defended. The rising wedge has an upper trendline that also slopes upward, so both boundaries converge while trending higher together. That flat ceiling in the ascending triangle is what makes it bullish: it identifies a known resistance price that, once broken, tends to produce clean and sustained follow-through. A sloping ceiling means you're looking at a rising wedge — a bearish setup in disguise.
