ZigZagOnParabolic MetaTrader 指標 — 基于兩種標準MT4/MT5指標 —ZigZag 和 拋物線轉向指標，該指標試圖通過在圖表上標記極值改進第一種指標，使滯后性更短。

標準ZigZag指標通過從先前極值中搜索價格偏差的百分比來尋找新的極值。新的ZigZag指標通過拋物線轉向指標也進行同樣的操作。ZigZag指標和拋物線轉向指標都顯示在圖表的頂部。該指標可用于MT4和MT5平臺。

輸入參數：

• Step (默認 = 0.02) — 標準拋物線轉向指標的參數之一。
• Maximum (默認 = 0.2) — 標準拋物線轉向指標的另一種參數。
• ExtremumsShift (默認 = true) — 如果設置為true，那么極值會顯示在實際的位置；如果設置為false，那么極值會顯示在被觀測到的那一點上。有助于查看極值實際出現與檢出點之間的延遲。
• History (默認 = 0) — 指標用來計算的天數。如果您的電腦運行很慢的話，可以進行更改。0 —使用所有的天數進行計算。

盡管ZigZag指標對真實交易信號效果不是很好，可以用于在最大和最小輸入短和長線位置。但此指標的主要用途是建立通道，模板和其它圖表。
