新文章 DoEasy 函数库中的时间序列（第五十四部分）：抽象基准指标类的衍生已发布：

本文研究基于基准抽象指标衍生对象类的创建。 这些对象所提供功能，可访问创建的指标 EA，收集和获取各种指标和价格数据的数值统计信息。 同样，创建指标对象集合，从中可以访问程序中创建的每个指标的属性和数据。

为了进行测试，我们需要上一篇文章中的指标，且无需进行任何修改。
简单地将其保存在新文件夹 \MQL5\Indicators\TestDoEasy\Part54\ 之下，新名称为 TestDoEasyPart54.mq5。

编译指标，并在图表上启动它。
在日志中将显示以下内容: all parameters of created indicator Accelerator Oscillator in full , and then its short description:
