说明：  这个abcd模式是最流行、最强大和最灵活的图表模式之一。这种模式由三个价格点组成：底部、峰值或谷地，斐波那契(Fibonacci)的回溯率在38.2%至71.8%之间。一种模式被认为是有效的，当价格突破最后的高峰或山谷，在这个时刻，指示符画出一个箭头，升起一个警报，交易可以放置。
(This abcdmodel is one of the most popular, powerful and flexible chart models. This model consists of three price points: bottom, peak or valley. Fibonacci's backtracking rate is between 38.2% and 71.8%. A pattern is considered valid when the price breaks through the final peak or valley, at which point the indicator draws an arrow, raises an alert, and the transaction can be placed.)
