用 C# 中的 2 条线指标计算 MACD 的 EMA

如何解决用 C# 中的 2 条线指标计算 MACD 的 EMA

我正在尝试编写一个指标脚本，该脚本将在练习交易工具中用 2 条线绘制 MACD。

目前，我遵循的公式是 using the EMA formula to calculate it.

我可以绘制图表。但不知何故，我的指标结果与元交易者 4 或交易视图上的结果并不完全相同。这些应用上的指标结果完全一样。

当我尝试从公式转换为实际代码时，我想我错过了一些东西。请帮我修复它。谢谢。

这是计算 EMA 的部分。

            Signal[i] = CalculateEMA_MACD(MACD,SignalEMA,i);
            Histogram[i] = MACD[i] - Signal[i];
        }
    }
