Bullish Symmetrical Triangle is a pattern consisting of two converging trend lines. This pattern means that the amplitude of price fluctuations is getting smaller and smaller, and that there may eventually be a short-term opportunity for price to break through upward and rise.
2.1 The top is getting lower and lower, and the bottom is getting higher and higher;
2.2 The price has recently broken through the downward resistance line formed by connecting the recent tops.
