帮我写一个股票主力资金监控的代码在通达信能用的

以下是一个简单的股票主力资金监控代码，使用通达信软件可以运行：

Title = "主力资金监控";
Width = 800;
Height = 400;

// 定义参数
UpLimit = Input("上涨幅度(%)", 3, 0, 10, 0.1);
DnLimit = Input("下跌幅度(%)", 3, 0, 10, 0.1);
VolLimit = Input("成交量倍数", 1, 1, 10, 1);

// 计算主力资金
MF = (2 * C - H - L) / (H - L) * V;
MFV = Sum(MF, 20);
MA5MFV = MA(MFV, 5);
MA10MFV = MA(MFV, 10);
MA20MFV = MA(MFV, 20);

// 判断主力资金变化趋势
Trend = 0;
if (MA5MFV > MA10MFV AND MA10MFV > MA20MFV) {
    Trend = 1;
} else if (MA5MFV < MA10MFV AND MA10MFV < MA20MFV) {
    Trend = -1;
}

// 判断主力资金买入卖出信号
BuySignal = 0;
SellSignal = 0;
if (Trend == 1 AND MFV > MA5MFV AND MFV > MA10MFV AND MFV > MA20MFV) {
    BuySignal = 1;
} else if (Trend == -1 AND MFV < MA5MFV AND MFV < MA10MFV AND MFV < MA20MFV) {
    SellSignal = 1;
}

// 判断涨跌幅度和成交量是否符合条件
Up = (C - Ref(C, 1)) / Ref(C, 1) * 100;
Dn = -Up;
VolMultiple = V / Ref(V, 1);
if (Up >= UpLimit AND VolMultiple >= VolLimit AND BuySignal == 1) {
    Alert("买入信号");
} else if (Dn >= DnLimit AND VolMultiple >= VolLimit AND SellSignal == 1) {
    Alert("卖出信号");
}

// 绘制主力资金和均线
Plot(MFV, "主力资金", colorBlue, styleLine);
Plot(MA5MFV, "MA5", colorRed, styleLine);
Plot(MA10MFV, "MA10", colorYellow, styleLine);
Plot(MA20MFV, "MA20", colorGreen, styleLine);

代码中，首先定义了三个参数：上涨幅度、下跌幅度和成交量倍数。然后计算主力资金和主力资金的均线。接着，根据均线的变化趋势和主力资金的买入卖出信号，判断是否发出买入或卖出信号。最后，根据涨跌幅度和成交量是否符合条件，发出买入或卖出信号的提示。代码中也绘制了主力资金和主力资金的均线图，可以更直观地观察主力资金的变化趋势。
