论文摘要
在本说明中，我们讨论了用于定义用于描述市场趋势的趋势指标的数学工具。我们一方面解释了平均值和移动平均值之间的关系，另一方面是所谓的指数移动平均值（EMA）。我们提供了很多示例，并给出了最常用的趋势指标，MACD的定义，并讨论其属性。
In this note we discuss the mathematical tools to define trend indicators which are used to describe market trends. We explain the relation between averages and moving averages on the one hand and the so called exponential moving average (EMA) on the other hand. We present a lot of examples and give the definition of the most frequently used trend indicator, the MACD, and discuss its properties.
