MACD(Moving Average Convergence Divergence)是一种常见的股票技术分析指标,用于判断股票价格的趋势和变化。
下面是一个使用Spring Boot编写MACD的简单实现:
1.首先,需要创建一个Stock类,来存储每日的开盘价,收盘价,最高价和最低价:
```
public class Stock {
private double open;
private double close;
private double high;
private double low;
// getter and setter methods
}
```
2.然后,创建一个包含MACD计算逻辑的类:
```
public class MACD {
private List<Stock> stockList;
// 构造函数
public MACD(List<Stock> stockList) {
this.stockList = stockList;
}
// 计算EMA(指数移动平均线)
private double getEMA(int n, double close) {
double k = 2.0 / (n + 1);
double ema = close;
for (int i = 0; i < n; i++) {
ema = k * close + (1 - k) * ema;
}
return ema;
}
// 计算DIF(差离值)
private double getDIF(int shortEMA, int longEMA) {
return shortEMA - longEMA;
}
// 计算DEA(信号线)
private double getDEA(int n, double dif) {
double k = 2.0 / (n + 1);
double dea = dif;
for (int i = 0; i < n; i++) {
dea = k * dif + (1 - k) * dea;
}
return dea;
}
// 计算MACD(移动平均收敛-发散指标)
public double getMACD(int shortEMA, int longEMA, int signal) {
double dif = 0;
double dea = 0;
// 计算DIF和DEA
for (int i = 0; i < stockList.size(); i++) {
double close = stockList.get(i).getClose();
double shortEMAValue = getEMA(shortEMA, close);
double longEMAValue = getEMA(longEMA, close);
double difValue = getDIF(shortEMAValue, longEMAValue);
dif += difValue;
if (i == signal - 1) {
dea = difValue;
} else if (i > signal - 1) {
dea = getDEA(signal, dif);
}
}
dif /= stockList.size();
dea /= stockList.size();
// 计算MACD
return (dif - dea) * 2;
}
}
```
3.最后,在Spring Boot应用程序中,可以将Stock列表传递给MACD类的构造函数,并调用getMACD方法来计算MACD值:
```
@RestController
public class MACDController {
@GetMapping("/macd")
public double getMACD() {
List<Stock> stockList = new ArrayList<>();
// 添加股票数据到列表中
MACD macd = new MACD(stockList);
return macd.getMACD(12, 26, 9);
}
}
```
这样就可以通过访问“/macd”端点获取MACD值了。
