Laguerre MT4 MT5指標源碼

Laguerre MetaTrader 指標 MT4 MT5指標 — 該指標適用于MT4和MT5。一種不依賴標準MT4/MT5指標的完全自定義的指標。它在一個單獨的圖表窗口顯示了加權趨勢線。可用作簡單的進出場信號。

輸入參數：

gamma (默認 = 0.7) — 乘數，用于計算趨勢線的水平。此數值越高，趨勢線越平滑。

CountBars (默認 = 950) — 計算該指標的最大天數。如果您希望該指標準確率更高，請設置盡可能高的數值。

當此線自下方接近0.2的水平時，Laguerre可用于做多，當此線自上方接近0.5的水平時，可關閉多頭頭寸。當此線自上方穿過0.8的水平時，做空；當此線自下方穿過0.5的水平時，關閉空頭頭寸。
