用.NET语言计算股票技术指标OBV的代码

以下是使用.NET语言计算股票技术指标OBV的代码：

public static double[] CalculateOBV(double[] closePrices, double[] volumes)
{
    double[] obvValues = new double[closePrices.Length];
    double prevObv = 0;

    for (int i = 1; i < closePrices.Length; i++)
    {
        if (closePrices[i] > closePrices[i - 1])
        {
            obvValues[i] = prevObv + volumes[i];
        }
        else if (closePrices[i] < closePrices[i - 1])
        {
            obvValues[i] = prevObv - volumes[i];
        }
        else
        {
            obvValues[i] = prevObv;
        }

        prevObv = obvValues[i];
    }

    return obvValues;
}

这段代码可以计算股票的OBV指标，其中`closePrices`是股票的收盘价数组，`volumes`是股票的成交量数组，返回值是OBV指标的数组。
