What Is an Ascending Triangle Chart Pattern?

An ascending triangle is a powerful technical analysis pattern with a predictive accuracy of 83%. It is flexible, can break out up or down, and can be a continuation or reversal pattern.

An ascending triangle has one inclining trendline connecting a series of higher lows and a second horizontal trendline connecting a series of highs. Depending on the direction of the price breakout, an ascending triangle can be bearish or bullish or a reversal or continuation pattern.

  • An ascending triangle occurring during a price uptrend, with a price breakout above the resistance line, is considered a bullish continuation pattern. (See chart below)
  • Conversely, an ascending triangle occurring during a price downtrend, with the price breaking out above the resistance line, is a reversal pattern.

TradingView’s powerful pattern recognition algorithms have autodetected this ascending triangle pattern. TradingView detected the pattern and set a price target equal to the length of the triangle’s apex. The target was flagged green once the target was achieved.

What the Ascending Triangle Indicates

The ascending triangle chart pattern occurs when sellers are in control at the resistance price points. As buyers become more active, demand starts to outstrip supply, and the lows move higher. Eventually, a breakout occurs in either direction, signaling a reversal or continuation of the trend.

The ascending triangle chart pattern is considered a reliable continuation or reversal point in the market, with an 83% success rate on an upward breakout in bull markets. Buyers begin to take control of the market when the price breaks above the triangle.

How Reliable is an Ascending Triangle Pattern?

An ascending triangle stock chart pattern has an 83% success rate on an upside breakout of an existing uptrend. When the price breaks through resistance, it has an average 43% price increase. Following a downtrend, the pattern is 79% successful, with an average price decrease of 16%.

Chart Pattern Ascending Triangle
Market Trend Bull Market
Success Rate 83%
Average Price Change +43%

It should be noted that this pattern does not guarantee a profit.

How to Identify an Ascending Triangle?

An ascending triangle is identified by two converging trendlines on a chart. The upper trendline represents the resistance, while the lower line represents support. As the price moves up and down between these lines, it creates a triangle pattern. When the price breaks above or below one of these lines, it indicates that bullish or bearish momentum is gaining strength. Investors should watch for a break above the upper trendline to enter long positions and look for a break below the lower trendline to enter short positions.

It is important to note that ascending triangles can be either continuation or reversal patterns, depending on the direction of the prior trend. If the market was in an uptrend before the triangle formed, then a break above the upper trendline is likely to lead to prices continuing in the direction of the prior trend. Similarly, if the market was in a downtrend before forming an ascending triangle, a break below the lower trendline could signal a continuation.

How to Draw an Ascending Triangle?

There are two simple steps for drawing the ascending triangle to prepare for the trade. (See the chart below)

  1. Draw the horizontal resistance trendline joining the price highs
  2. Draw the support trendline connecting the higher lows

If the security price breaks out above the triangle resistance, especially with volume increases, it signals a possible 83% chance of going higher. Generally, the pattern should be visible on an intraday or daily chart. After identifying the triangle, we need to measure and set a price target.

Trading an Ascending Triangle Pattern

When trading this chart pattern, it is important to set your stop loss inside the triangle pattern and adjust your target level based on the breakdown size. You can expect a target of 50% up to 100% of the distance from the entry point to the triangle resistance line.

Traders should pay attention to volume when trading an ascending triangle chart pattern. Higher volume on the breakout is often considered a confirmation of trend reversal in this setup (see above chart). This means traders should be vigilant and wait for higher volumes before entering a trade on any breakout situation.

Entry and Exit Points

The entry point for an ascending triangle pattern is at the price breakout of the triangle, either up or down. Traders should place a stop-loss order below or above the breakout to protect against potential losses. The exit point can be determined by placing an initial target at 50% of the triangle’s height. (See Chart Above)

It is also important to remember that ascending triangles can fail at a rate of 17%, and traders should always have an exit strategy in case of a failed pattern. Furthermore, managing risk during any trade is essential, as the potential for loss is still real. Using proper risk management techniques, traders can maximize profits while limiting losses.

How to Measure & Set a Price Target.

If the distance from the triangle peak to the horizontal support is 10%, the logical price target should be 10% above the breakout. It is calculated by adding the pattern’s height to the breakout point. This gives traders a good indication of where to expect prices to move following a successful breakout. Once the ascending triangle breakout is confirmed, traders should set their stop-loss order just below the breakout zone.

The Ascending Triangle Pattern Timeframe

Ascending triangles can form on any timeframe but occur more frequently on intraday charts, 5, 15, or 60-minute time frames. This makes the ascending triangle a great pattern for day traders. An ascending triangle with a perfectly horizontal resistance line is rare, but it is OK if there is a slight incline.

Even on an hourly time frame, an ascending triangle pattern typically takes weeks to form. Traders should monitor the stock over a medium-term period on an hourly or daily chart and be prepared to enter at any time to maximize potential profits.

It is important to consider volume as an additional indicator when attempting to identify and trade the ascending triangle pattern.

What Happens After an Ascending Triangle Pattern?

Two decades of research by Tom Bulkowski show that after an ascending triangle pattern is confirmed on a break of either the support or resistance line on higher volume, the price increase averages +43%.

Once the ascending triangle pattern is confirmed, traders should consider opening a long or short position depending on the direction of the price move.

What Happens with a Failed Ascending Triangle Pattern?

An ascending triangle in a bull market fails 17% of the time. When an ascending triangle pattern fails, the stock price fails to achieve the price target or reverses back to the breakout zone. At this point, it makes sense to discard the pattern.

An Ascending Triangle Pattern in an Uptrend

The ascending triangle often forms within an existing uptrend in a bull market. This is usually a sign of strength and often results in the continuation of the uptrend. Traders should be aware that this pattern may provide false signals, as it does not guarantee that the trend will continue, and prices could reverse at any time.
