Regarding the risk of buying long orders, let me tell you that the last rise of the symmetrical triangle requires heavy volume to break through the first high point (1742u). This is the relay form in the upward trend and the original trend is restored. However, according to my past opinions The prediction of the trend has always been very accurate, so there is a high probability that a huge wave of volume will be released to directly accelerate the rise and break through the trend line pressure level. When the trend line is opened, it will be a vacuum period!
