第三代移动平均线 MT4 MT5指标[MT5公式]

该指标适用于MT4 和 MT5。无需使用任何DLL。

第三代移动平均线 MetaTrader 指标 — 是标准移动平均线（MA）的先进版，在较长MA时段执行简单的减少滞后性的程序。这种方法由M. Duerschner首次描述于他的文章Gleitende Durchschnitte 3.0(德语)。当前版设定λ = 2，最大程度的减少了滞后性。较高的λ值则会增加与经典移动平均线的相似性。

这是个MetaTrader指标，用于可调整移动平均线 3G智能交易。

输入参数：

MA_Period (默认 = 50) — 第三代移动平均线的时段。

MA_Method (默认 = 1) — 移动平均线的方法。0 — SMA, 1 — EMA, 2 — SMMA, 3 — LWMA.

MA_Applied_Price (默认 = 5) — 移动平均线适用的价格。0 — PRICE_CLOSE, 1 — PRICE_OPEN, 2 — PRICE_HIGH, 3 — PRICE_LOW, 4 — PRICE_MEDIAN, 5 — PRICE_TYPICAL, 6 — PRICE_WEIGHTED.

正如您看到的，第三代移动平均线（红线）比传统的指数移动平均线（蓝线）滞后性更短，而且能更快的反映出价格的变化。不过，它仍有滞后性而且可能会发出错误的信号。您可以将第三代移动平均线外汇指标作为标准移动平均线使用 — 用以侦测当前趋势的方式。
