The Ascending Triangle is a bullish continuation chart pattern (occasionally a reversal) formed by a flat horizontal resistance line at the top and an upward-sloping support line at the bottom. Price oscillates between the two lines, making progressively higher lows while each rally attempt hits the same flat resistance. The two lines converge, building pressure until price breaks above the resistance with force.

How to Identify

• Flat resistance: a near-horizontal line connecting at least two price highs at the same level
• Rising support: an upward-sloping line connecting at least two higher lows
• The two lines converge — the pattern narrows over time, creating a right triangle shape
• Price should touch each line at least twice (ideally 3+ touches each) before the breakout
• Each pullback is shallower than the previous — buyers are stepping in at higher and higher levels
• Volume typically contracts during the pattern and expands sharply on the breakout
• Breakout above the flat resistance confirms the pattern
• Price target: measure the widest height of the triangle and add to the breakout point
• Pattern typically takes 3–12 weeks to develop

Market Psychology

The flat resistance represents a supply zone — sellers consistently step in at that price level. But the rising lows show that buyers are increasingly aggressive: each dip attracts buyers at a higher price than before. The balance of power is shifting toward the bulls.

As the two lines converge, the pattern reaches an apex. The longer it takes to break out, the more energy is stored. When price finally pushes through the resistance level, short sellers are forced to cover and breakout buyers pile in, creating a rapid acceleration higher.
