The symmetrical triangle pattern can be either bullish or bearish, depending on the market. In either case, it is normally a continuation pattern, which means the market will usually continue in the same direction as the overall trend once the pattern has formed.
Symmetrical triangles form when the price converges with a series of lower peaks and higher troughs. In the example below, the overall trend is bearish, but the symmetrical triangle shows us that there has been a brief period of upward reversals.
However, if there is no clear trend before the triangle pattern forms, the market could break out in either direction. This makes symmetrical triangles a bilateral pattern – meaning they are best used in volatile markets where there is no clear indication of which way an asset’s price might move. An example of a bilateral symmetrical triangle can be seen below.
