該指標適用于MT4和MT5。全稱為Quantitative Qualitative Estimation，是一種非常復雜的基于平滑相對強弱指標的算法的指標。使用該指標，會在一個獨立的窗口看到2條線 —一快線，一慢線。還有一個重要的用于發送信號指標水平（50）。您可以啟用文本、聲音和電子郵件示警。

輸入參數：

SF (默認 = 5) — 一種平滑系數。

AlertLevel (默認 = 50) — 示警的指標水平。不建議進行更改。

MsgAlerts (默認 = true) — 如果選擇為true，將提供消息示警。

SoundAlerts (默認 = true) — 如果選擇為true，將使用聲音示警。

SoundAlertFile (默認 = "alert.wav") — 一個聲音示警的聲音的文件名稱。

eMailAlerts (默認 = false) — 如果選擇為true，那么將按照MetaTrader電子郵件的設置發送電子郵件示警。

在原始QQE指標交易系統中，當藍線穿過50的水平時以及穿過黃（點）線時發出信號。但是建議使用如下交易信號：當藍線自下方穿過黃線而且兩者均低于50水平時，做多；當藍線自上方穿過黃線而且兩者均高于50水平時，做空。
