“杠杆叠加原理”是zhangge根据＂道氏理论＂及＂Bill Williams ＂的相关理论，取其精髓经过叠加并进行有效地量化而成。简单的一句话概括如下：

当价位有效突破一条相对较长期的趋势线，且形成“张氏分形”时，之后的价位运行空间将是“张氏分形”中k线实体的至少1倍.

"杠杆" 是指压力线的有效破位；

"叠加"是指价位未来预期的运行空间。

具体图例解释请见下面各篇文章中的详细说明.

 《Zhangge's Trend Double Principle》brief introdiction:         　　　The Principle was invented by a Professional Currency Analyst cum Academician from China. His name is Mr. Zhang Ge. Zhangge's Trend Double Principle effectively combines the essence of Dow's Theory and the Fractals Theory from Bill Williams. When　the　price　of　a　commodity/currency break into a major support or resistance line, and at the same time forms an effective reversal pattern, the price target after the reversal pattern would be at least greater or equal to the combined height of the real body of the reversal pattern. Zhangge's Trend Double Principle can be used to forecast the price action of a currency pair provided basic rules of the principle are met. Please find the pictorial in my blog' articles.
