在上述代码中添加副图表加载 MACD 指标的部分，可以使用iMACD函数来计算和绘制 MACD 指标。以下是更新后的代码：

    // 检查当前魔术码下的多单持仓是否为0

        }
    }

    // MACD金叉的时候做多
    if (!hasLongPosition)
    {
        OpenBuyOrder(INITIAL_LOTS);
    }

    // 绘制MACD指标
    int macdHandle = iMACD(Symbol(), PERIOD_CURRENT, 12, 26, 9, PRICE_CLOSE);
    if (macdHandle != INVALID_HANDLE)
    {
        CopyBuffer(macdHandle, 0, 0, 100, ExtMapBuffer1);
        CopyBuffer(macdHandle, 1, 0, 100, ExtMapBuffer2);
        CopyBuffer(macdHandle, 2, 0, 100, ExtMapBuffer3);
    }

    CloseOrders();
    return;
}

在OnInit函数中，我们添加了指标相关的设置，定义了三个指标缓冲区用于绘制 MACD 指标的线和直方图。

在OnTick函数中，我们使用iMACD函数计算 MACD 指标，并使用CopyBuffer函数获取指标的值，并将其存储在指标缓冲区中。这样，我们就可以在副图表中绘制出 MACD 指标。

请确保您已经正确设置了指标的输入参数和图表属性。如果还有问题，请提供更多详细信息，以便我能够帮助您进一步调试。
