# 迪马克 (DeMarker)

迪马克技术指标 (DeM) 取当前周期最大值并与前一周期最大值进行比较。如果当前周期 (柱线) 数值较高，就登记两者间的差值。如果当前最大值低于或等于前一个周期的最大值，则登记空值。得到 N 个周期的差值后汇总，所得数值作为迪马克的分子，然后将其除以相同数值加上前一周期与当前周期 (柱线) 最小值的差值的总和。如果当前价格的最小值大于前一根柱线，则登记空值。

当指标低于 30 时，可以期待牛势反转。当指高于 70 时，应期待熊势反转。

如果您使用持续时间较长的周期，当计算指标值时，您就能够捕捉一个长线的行情趋势。若指标基于持续时间比较短的周期，可令您在一个风险较小的点位入场，并可以规划交易时间，使之与主要趋势一致。

## 计算

间隔为 "i" 的迪马克数值计算如下:

DeMax(i) 的计算。如果 HIGH (i) > HIGH (i - 1)，那么:

```
DeMax (i) = HIGH (i) - HIGH (i - 1)
```

否则

```
DeMax (i) = 0
```

DeMin(i) 的计算。如果 LOW (i) < LOW (i - 1), 则:

```
DeMin (i) = LOW (i - 1) - LOW (i)
```

否则

```
DeMin (i) = 0
```

迪马克数值计算:

```
DMark (i) = SMA (DeMax, N) / (SMA (DeMax, N) + SMA (DeMin, N))
```

其中:

HIGH (i) ― 当前柱的最高价格;
LOW (i) ― 当前柱的最低价格;
HIGH (i - 1) ― 上一时段的最高价格;
LOW (i - 1) ― 上一时段的最低价格;
SMA ― [简单移动平均线](https://www.metatrader5.com/zh/mobile-trading/android/help/chart/indicators/trend_indicators/moving_average#sma);
N ― 计算中使用到的周期。
