Symmetrical Triangles Explained A symmetrical triangle chart pattern represents a period of consolidation before the price is forced to breakout or breakdown. A breakdown from the lower trendline marks the start of a new bearish trend, while a breakout from the upper trendline indicates the start of a new bullish trend. The pattern is also known as a wedge chart pattern.
The price target for a breakout or breakdown from a symmetrical triangle is equal to the distance from the high and low of the earliest part of the pattern applied to the breakout price point. For example, a symmetrical triangle pattern might start at a low of $10 and move up to $15 before the price range narrows over time. A breakout from $12 would imply a price target of $17, or $15 – $10 = $5, then + $12 = $17.
