A symmetrical triangle chart pattern represents a period of consolidation before the price is forced to breakout or breakdown. The symmetrical triangle, which can also be referred to as a coil, usually forms during a trend as a continuation pattern. The pattern contains at least two lower highs and two higher lows. When these points are connected, the lines converge as they are extended and the symmetrical triangle takes shape. You could also think of it as a contracting wedge, wide at the beginning and narrowing over time.
