Triangle Law is a law that was put forward by Qiu Hao in 2009 and is suitable for futures trading. This law extends operations in two directions of multidimensional space through time dimension to form a triangle. The formation and evolution of the trend are quantitatively explained by the angle and side length of the triangle.

The function of this law is to judge the direction and potential of future trend through the angle and form of graphics in the early stage of the market. Use mathematical geometry to make a logical explanation of what people often say is "disk feeling"

Correlation principle:

The trigonometric law is profound, but concise. Its connotation expounds the relationship between time and space, the alternating process of things' development, the essence of causal cycle, and also expounds and understands the yin and yang poles of Taoism from a new angle. Yin and yang are infinite, empty and powerless, and causality is wireless. This is originally a binary number, and neither ternary nor binary can be operated to form a circular replacement. So the triangle law is a complete law of development, and there are three things that have not been formed.
