MT4-AIS Basic Window Functions

该脚本旨在评估各种窗口函数中的权重。基于这些窗口函数构建的指标可以在 https://www.mql5.com/ru/market/product/72160 下载

输入参数：

iPeriod – 指标周期。 iPeriod >= 2

iCenter 是窗口函数中心所在的参考索引。默认情况下，此参数为 0 - 窗口中心与指标中心重合。当 1 <= iCenter <= iPeriod 时，窗口函数的中心将移动，因此指标的某些特征将发生变化。在图 1 中，您可以看到中心的选择如何影响窗口功能和指标的显示。此参数可以以 0.5 为增量进行更改。

Histogram width - 直方图的宽度。

Histogram color - 直方图的颜色。

Show duration - 显示持续时间。

Screenshot - 启用此选项时，图片将保存在 Files 文件夹中。

一些窗口函数使用附加参数 - ParameterA 和 ParameterB。它们会影响窗口权重。正因为如此，指标的特性发生了变化。该表显示了窗口函数和更改参数的限制（如果使用它们）。
