Var Mov Avg MetaTrader 指標

該指標通過價格曲線在主圖表窗口顯示虛線。當該虛線顏色發生變化時，會發出趨勢更改的信號。該指標可以在趨勢變化時發送聲音示警。您可以打開或關閉此功能。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出更準確的信號。

輸入參數：

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，此數字越高，此線越不平滑。
nfast (默認 = 15) — 第一個噪聲濾波器參數。此數值越高，指標發出的信號越少。
nslow (默認 = 10) — 第二個噪聲濾波器參數。此數值越高，指標發出的信號越少。
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。使用適當的止損保護由錯誤信號造成的損失。
