While textbooks classify the symmetrical triangle as a bullish continuation, it more often results in sideways price movement or insignificant breakouts, resembling a normal move within a trading range, and is best avoided.
"in most textbooks they will say that this pattern should lead to an uptrend... but you will probably find even more examples when this pattern turns out to just lead to the price going sideways... I personally avoid these patterns because so many times s this breakout right here will turn out to not be significant and the breakout will actually be a normal move within a simple trading range"
