Pattern Recognition Master MT4 MT5指標[MT5公式]

作者：MT4 MT5 來源：本站原創發布時間：2012年05月13日點擊數：　【收藏到本網的會員中心】

該指標適用于MT4和MT5平臺。

這種指標可幫您處理日常工作，可在圖表上使用與相應形態相符的名稱（像十字星或流行）標記蠟燭圖。您需要做的僅是觀察這種圖表形態是上漲還是下跌，檢查一般趨勢，決定您的交易立場。您可以參考日本蠟燭圖形態列表以便快速找出有價值的形態信號。

輸入參數：

Show_Alert (默認 = true) — 如果設置為true，那么當監測到一定形態后會示警。

UseExtraDigit (默認 = false) — 如果您的經紀公司的報價使用額外數字（點），那么您應設置為true。

其它參數 — 打開或關掉多種形態的顯示。建議不要更改此項。

首先，您應該理解該指標僅能暗示形態。您會在蠟燭臺附近看到這些符號，還會在屏幕左上角看到這些符號的圖例。第二，您需要知道這些形態有什么作用，何時是空頭頭寸的信號，何時是多頭頭寸的信號。對于經驗豐富的日本蠟燭臺形態的交易商來說，該指標是一種非常有用的工具，但對于其他交易商來說，可能毫無用處。
