补充资料：波浪幅度相等规则
波浪幅度相等规则
数浪的型态交替规则之五性的是第3浪会出现延长。如果两个推动浪不相等，仍然会以0.618的黄金比率，出现相互对等的关系。对较大级数的价格波动周期，浪与浪之间的关系，不能纯粹以波动幅度来计算，而须改用百分比来计算幅度。对于较小级数的价格波动周期，浪与浪之间的关系，可用实际数目来表示。例如，美国股市1卯6年年底第1浪持续时间为47小时，幅度达35.24点。而第5浪则同样持续了47小时，幅度达34.40点，这说明波浪幅度相等规则是相当准确的。【波浪幅度相等规则]在第1、3、5浪的三个推动浪中，其中有两个浪在时间和程度上趋于接近，有一个浪会出现延长波浪，更具准确
