ZigZag函數顯著地高點和低點所連結之趨勢線是為了讓使用者連續到被看

之函數。

Z字轉向指標(ZigZag)是一種表示價格趨勢的指標。它的原理是去過濾較為不重要

的影響因素，爾後再分析價格的移動趨勢。所以可藉由它來建立一組忽略較小的

價格變化的價格指標。該指標的特性為很單純的從大幅度的價格變化來判斷價格

的趨勢，而不會受到不適用的指標干擾。

計算方法-A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines　it can be described as both jagged and fairly regular. Traditionally a "zig" points in the left direction (/) and a "zag" points right (\). From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection.
