Ascending Triangle
uh-sen-ding trai-ang-gul
An ascending triangle is a bullish chart pattern that usually appears during an uptrend.
It is formed by:
A flat (horizontal) resistance line at the top
A rising support line at the bottom (higher lows)
This shows that buyers are becoming stronger over time, while sellers are unable to push the price lower. The price keeps pressing against the same resistance level.
A breakout above the resistance, especially with strong volume, usually signals a continuation of the uptrend.
In some cases, it can act as a reversal pattern in a downtrend, but that is less common.
In February 2024, ICICI Bank’s stock formed a clear ascending triangle on the daily chart. The stock was trading between ₹950 and ₹1,050, with multiple failed attempts to break above ₹1,050, creating a strong resistance level.
At the same time, each decline ended at a higher level than before, forming a rising support line. This showed that buyers were stepping in earlier, slowly gaining control.
During the formation, trading volumes were relatively low. But when the stock finally broke above ₹1,050 with strong volume, it confirmed the pattern. The price then moved up to around ₹1,120 in the following sessions.
This is a typical example of consolidation followed by a continuation of the uptrend.
• 1948 – Pattern Documented
The ascending triangle was formally described in by Edwards and Magee.
• Early 20th Century – Dow Theory Influence
The idea of rising lows and resistance levels comes from Dow Theory, which shaped modern chart patterns.
• 1980s Onwards – Widespread Use
With the growth of charting software, patterns like the ascending triangle became widely used by traders for breakout strategies.
