該指標通過價格曲線在主圖表窗口顯示虛線。當該虛線顏色發(fā)生變化時，會發(fā)出趨勢更改的信號。該指標可以在趨勢變化時發(fā)送聲音示警。您可以打開或關(guān)閉此功能。該指標可用于MT4和MT5。

雖然該指標基于移動平均線，但它不使用任何標準MT4/MT5移動平均線指標。它使用自身的計算公式計算使用噪聲濾波器的移動平均線進而發(fā)出更準確的信號。

輸入?yún)?shù)：

• periodAMA (默認 = 50) — 主要自定義移動平均線的時段。與其它移動平均線不同，此數(shù)字越高，此線越不平滑。
• nfast (默認 = 15) — 第一個噪聲濾波器參數(shù)。此數(shù)值越高，指標發(fā)出的信號越少。
• nslow (默認 = 10) — 第二個噪聲濾波器參數(shù)。此數(shù)值越高，指標發(fā)出的信號越少。
• G (默認 = 1.0) — 移動平均線中過濾部分的力量。這是另一種使信號線更平滑的方式。
• dK (默認 = 0.1) — 實際上并無多大影響。
• UseSound (默認 = true) — 如果設(shè)置為true，將啟用聲音示警。
• SoundFile (默認 = "expert.wav") — 示警使用的聲音文件的名稱。

當虛線變成紅色時，價格處于下跌趨勢。當虛線變綠時，價格處于上升趨勢。當虛線由紅變綠時，做多；由綠變紅時，做空。使用適當?shù)闹箵p保護由錯誤信號造成的損失。
