Triangle chart patterns: A smarter way to technical analysis

Have a trading plan ready for when the price breaks triangle support or resistance trendlines. Use strategies to profit from upside and downside breakouts from triangles.

For decades, investors, experts, and speculators have relied on technical analysis.  Technical analysis employs triangles as chart patterns, which are a vital tool for speculating about future market moves and trading possibilities. These patterns get their name from the triangle shape in which they appear and connect the upper and lower trendlines.   

But before we jump into the depths of the triangle chart patterns in stocks, their types, and their differences, let’s take a brief look at what technical analysis is.

What is a technical analysis?

Technical analysis is a kind of trading approach in which traders examine markets and forecast future moves based on historical data. Rather than focusing on company performance, this trading approach evaluates past data, such as asset prices and trade volumes, using strategies and instruments. Triangles and candlesticks are among the charts and graphs that are employed as tools in technical analysis.

What is a triangle pattern?

In the stock market, triangle chart patterns are continuation patterns that can be defined as horizontal patterns in trading. The triangle is the widest when it first forms. The triangle’s tip emerges while the market keeps moving sideways, and the trading range gets smaller.

Triangle formations are often seen on charts by traders when an asset’s price narrows its trading range following an uptrend or a downtrend. Triangle formations on charts can predict either a reversal or an extension of the preceding trend, unlike other patterns that provide a definite directionality for the upcoming price shift. Traders must patiently wait for a triangle breakout before reacting to this chart pattern, even though triangles more often indicate a continuation of the preceding trend.

Explaining triangle patterns in technical analysis

Triangle chart patterns are a part of technical analysis, a trading approach where traders analyse charts and patterns to discover market movements and forecast their potential. Triangular patterns get their name because the upper and lower trendlines eventually come together to form an angle at the right side’s apex. These patterns appear when a stock’s or another security’s trading range gets smaller.

The remaining two angles of the triangle are completed by joining the starting point of the lower trendline with the start of the top trendline. The upper trendline is created by joining the highs, and the lower trendline is created by connecting the lows.

Triangles are comparable to other technical analysis tools, including pennants, recurrent patterns created when an asset displays significant activity, and wedges, price patterns identified by parallel trendlines. If proven correct, they can be a powerful reversal or continuation pattern. Traders use triangles to indicate when a stock or security’s trading range narrows following a rising trend or downturn.

As price activity shapes a holding pattern, three possible triangle variations can emerge—ascending, descending, and symmetrical triangles—can emerge. When a triangular pattern breaks, especially on high volume, technicians interpret these events as strong indications of either a continuation or reversal of the previous trend.

Different types of triangle chart patterns

Triangles come in three varieties, and it is important to examine each one thoroughly. These structures are the symmetrical triangle, the descending triangle, and the ascending triangle.

Ascending triangle pattern

A set of two trendlines, one rising and the other horizontal and combining a sequence of higher lows, make up an ascending triangle.

The bullish chart pattern indicates that buyers are getting more aggressive, while the resistance line establishes a threshold that the price finds it difficult to break around. Because of this, the ascending triangle indicates a stage of stability before a possible upward triangle pattern breakout.

Descending triangle pattern

When the value of investment makes a string of lower highs yet finds support around a horizontal trendline, a descending triangle is created. This bearish chart pattern results in the formation of a downward-slanted triangle. The horizontal lower trendline represents a level of support that has been tested numerous times, while the downward-sloping higher trendline serves as a level of resistance. This pattern points to a probable breakdown and indicates that sellers are becoming more in command of the market.

Symmetrical patterns

Thus far, we have observed two triangular patterns: one originating from an upward trend and bullish market movement, and another from a downward trend that has a distinctly bearish appearance. Conversely, symmetrical patterns are seen as recurrent trends that emerge in markets that are largely directionless. The market appears indifferent to it. As a result, it appears that supply and demand are the same.

Ascending and descending triangles: connections and distinctions

There are a number of parallels and distinctions between descending and ascending triangles to take into account. Both patterns, which are made up of successive higher lows or lower highs, are referred to as continuation patterns. They may also point to possible price fluctuation breakthroughs. 

But these patterns also differ from one another. Triangles that are ascending have a flat resistance level, and triangles that are falling have a flat support level. Furthermore, ascending triangles generally indicate a bullish sentiment and descending triangles indicate a bearish sentiment. In general, to make wise trading selections, traders should closely examine the similarities as well as the distinctions between these two patterns.


One of the most important duties of any share market analyst is to recognise patterns, and the two major charts are triangle patterns and candlestick patterns. Triangle candlestick patterns combine data from several periods into an individual price bar. On the other hand, the fundamental elements of technical analysis are chart patterns. They are quite easy to identify and recur throughout the market period. 

The bottom line is that, technical analysis calls for a significant degree of patience and discipline as with any trading instrument utilised in this method.
