Symmetrical Triangle Pattern: Definition & Interpretation

Key Highlights

  • A symmetrical triangle is a chart pattern formed by two converging trend lines. Both trend lines should meet at roughly the same slope. In cases where their slopes are unequal, they become ascending or descending triangles.

  • Traders often use this pattern to predict breakouts or breakdowns by looking for converging trend lines and decreasing price volatility.

  • While symmetrical triangles are generally reliable, there are times when false breakouts cause trends to reverse. A trader must be prepared with strategies for managing risk in these situations.

The symmetrical triangle chart pattern is characterized by two trend lines converging into a series of peaks and troughs. Both trend lines should converge at roughly the same slope, forming a triangle. The trend lines are no longer symmetrical if they converge at unequal slopes. In that case, the lines are known as ascending triangles or descending triangles.

According to many trading experts, a symmetrical triangle can be identified by observing the length of the trendline. The trend can confirm whether the pattern is a symmetrical triangle pattern or just a temporary flat or pennant based on whether it has been observed for days or months. The pattern is most likely a symmetrical triangle if it is observed over several months. It is probably a pennant or a flag if it is only a few weeks old.

Having understood the symmetrical triangle pattern breakout meaning, let’s understand how to identify the pattern. It is relatively easy to identify a symmetrical triangle pattern. Two elements are essential to traders: converging trend lines and decreasing volatility. The pattern is drawn by connecting two swing highs to an upper trendline and two swing lows to a lower trendline. At the apex, the trendlines should meet.

Additionally, the volatility within the triangle decreases as the price fluctuates within a narrower range. In the near future, there may be a breakout or breakdown due to the reduction in price swings.

It is a variation of the symmetrical triangle pattern. In this pattern, the lower trendline ascends, and the upper trendline remains flat. This indicates a bullish bias and indicates buyers become more aggressive as the price consolidates. In order to make money, traders look for breakouts above the upper trendline.

Another variation of the symmetrical triangle pattern is the descending triangle pattern. In this pattern, the upper trendline descends while the lower trendline remains flat. With the price consolidating, sellers become more dominant, indicating a bearish bias. Traders often look for a breakdown below the lower trendline to indicate a downward move.

Symmetrical triangle patterns are often used by traders to predict breakouts and breakdowns. The following points should be considered when trading this pattern:

  • Confirmation: Before entering a trade, wait for a confirmed breakout or breakdown. Breakouts occur when the price breaks above the upper trendline, while breakdowns occur when the price drops below the lower trendline.

  • Volume: Breakouts or breakdowns should be accompanied by increased trading volume, which indicates strong market interest.

  • Price Target: If the breakout is bullish, measure the height of the triangle pattern, whereas if it is bearish, measure it downward. For the trade, this provides an initial price target.

  • Stop Loss: Place a stop-loss order below the breakout point for a bullish breakout or above the breakdown point for a bearish breakout to limit potential losses.

You should remember that symmetrical triangle patterns can result in false breakouts if they are not foolproof. Thus, it is important to use other technical indicators as well as perform thorough analysis in order to increase the probability of a successful trade.

In general, symmetrical triangles are reliable, but there are instances when the pattern does not predict the continuation of the previous trend. A failure occurs when the price breaks out of the pattern but quickly reverses and moves in the opposite direction. In the event of a false breakout, traders should have appropriate risk management strategies in place to mitigate losses.

  • Before a triangle pattern occurs, always be aware of the trend direction.
  • Failure of the triangle pattern often signals the reversal of a trend and is usually accompanied by a range of top patterns such as head and shoulders, Morning Stars, or Evening Stars before the reversal.
  • Unless you receive a confirmation on the breakout direction, do not take a position if you are a new trader.


A symmetrical triangle pattern can be used by technical analysts to identify consolidation periods and anticipate breakouts and breakdowns. There is a temporary balance between buyers and sellers in this pattern, resulting in a decrease in volatility. To make informed trading decisions, traders can use the symmetrical triangle pattern and other technical indicators. Traders can take advantage of the opportunities presented by symmetrical triangles by spotting the pattern and applying appropriate trading strategies.

FAQs on Symmetrical Triangle Pattern Breakout

When there is a temporary pause in the prevailing trend, a symmetrical triangle pattern occurs. It indicates a period of indecision between buyers and sellers, where the price consolidates within the converging trendlines.

In a symmetrical triangle pattern, breakouts from lower trend lines mark the beginning of a new bearish trend, while breakouts from upper trend lines indicate the beginning of a new bullish trend.

A false triangle breakout occurs when the price breaks out of the pattern and then moves back into it, fooling traders who traded the breakout. It is a common occurrence in the market.

There are two converging trend lines connecting sequential peaks and troughs in a symmetrical triangle chart pattern. A pennant pattern is a continuation pattern in which a period of consolidation is followed by a breakout.
