該指標可用于MT4和MT5。

在主圖表窗口顯示當前的點差。您可以修改字體參數，指標的位置和點差的標準值。點差在每次變動之后都會重新描繪，以確保為最新、有效的點差值。這對那些提供浮動點差或點差經常擴大的經紀商非常有用。

輸入參數：

• font_color (默認 = Red) — 點差指標的顏色。
• font_size (默認 = 14) — 點差指標的大小。
• font_face (默認 = "Arial") — 點差指標的字體。
• corner (默認 = 0/ANCHOR_LEFT_UPPER) — 點差指標的位置。在MT4上：0 —左上角，1 —右頂部，2 —左底部，3 —右底部。在MT5上，非常明顯。
• spread_distance_x (默認 = 10) — 自角落到指標的水平距離。
• spread_distance_y (默認 = 130) — 自角落大指標的垂直距離。
• normalize (默認 = false) — 如果設置為true，那么點差值為標準化的，將賦予一個常用的點值。如果設置為false，那么點差值將賦予當前的點值。對非標準化的報價非常有用。
• AlertIfSpreadAbove (默認 = 0) — 在大于零時，當點差超過給定值的時候就會發出聲音示警。

該指標不會發出交易信號。僅能輔助您做出交易決定，設置適當的止損或止盈水平以及以一種簡單、快速的方式通知您當前市場的形勢。
