該指標適用于MT4和MT5。

當價格到達交易商設置的價位時，會發出聲音示警的指標。有三種類型的示警：第一種用于價格上漲至設定價位的上方時（在圖表上顯示為綠線），第二種用于價格下跌至設定價位的下方時（在圖表上顯示為紅線），第三種用于價格接近某一確切的價位時（顯示為黃線）。所有的示警在被觸發之后，都會關閉，但當設定新值之后，可以再次開啟。如果您使用電子郵件示警功能，那么不要忘記在您的MetaTrader平臺選項窗口設置電子郵件設置。

輸入參數：

SoundWhenPriceGoesAbove (默認 = 0.0) — 如果價格上漲至此值的上方將觸發示警。

SoundWhenPriceGoesBelow (默認 = 0.0) — 如果價格下跌至此值的下方將觸發示警。

SoundWhenPriceIsExactly (默認 = 0.0) — 如果價格到達此值時將觸發示警。

SendEmail (默認 = false) — 如果選擇為true且正確的電子郵件設置已經設置在MetaTrader選項窗口，那么示警將發送到設置的電子郵箱地址。

該指標不能用作一種交易系統，它不產生任何信號。無論何時您希望收到某一新價位的通知時，您都可以使用該指標。之后，您可以利用您的時間在市場上做一些您想做的事情。如果您不想使用它們中的某些，您可以將輸入參數設置為零。
