高级程序员鉴定题：用java如何编写通达信SKDJ指标？
高级程序员鉴定题：用java如何编写通达信SKDJ指标？
LOWV:=LLV(LOW,N);
HIGHV:=HHV(HIGH,N);
RSV:=EMA((CLOSE-LOWV)/(HIGHV-LOWV)*100,M);
K:EMA(RSV,M);
D:MA(K,M);
请教写个能测通的demo
结果如图，数据如下：

用一个简单的股票价格类，一个计算LLV, HHV, EMA, MA的实用类，以及一个计算SKDJ的方法。
public class StockPrice {
private final double low;
private final double high;
private final double close;
public StockPrice(double low, double high, double close) {
this.low = low;
this.high = high;
this.close = close;
}
public double getLow() {
return low;
}
public double getHigh() {
return high;
}
public double getClose() {
return close;
}
}
计算LLV, HHV, EMA, MA的实用方法：
public class IndicatorUtil {
public static double llv(List<StockPrice> prices, int n) {
return prices.stream()
.limit(n)
.mapToDouble(StockPrice::getLow)
.min()
.orElse(Double.NaN);
}
public static double hhv(List<StockPrice> prices, int n) {
return prices.stream()
.limit(n)
.mapToDouble(StockPrice::getHigh)
.max()
.orElse(Double.NaN);
}
public static double ema(List<Double> data, int n) {
double multiplier = 2.0 / (n + 1);
double ema = data.get(0);
for (int i = 1; i < data.size(); i++) {
ema = (data.get(i) - ema) * multiplier + ema;
}
return ema;
}
public static double ma(List<Double> data, int n) {
return data.stream()
.limit(n)
.mapToDouble(Double::doubleValue)
.average()
.orElse(Double.NaN);
}
}
用以上的工具类和方法来计算SKDJ指标：
public class SkdjIndicator {
public static Pair<Double, Double> calculateSkdj(List<StockPrice> prices, int n, int m) {
double lowv = IndicatorUtil.llv(prices, n);
double highv = IndicatorUtil.hhv(prices, n);
List<Double> rsvs = new ArrayList<>();
for (StockPrice price : prices) {
double rsv = (price.getClose() - lowv) / (highv - lowv) * 100;
rsvs.add(rsv);
}
double k = IndicatorUtil.ema(rsvs, m);
double d = IndicatorUtil.ma(rsvs, m);
return new Pair<>(k, d);
}
}
以下是使用Java编写的通达信SKDJ指标的代码示例：
```java
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.List;
public class SKDJIndicator {
public static void main(String[] args) {
int N = 9;
int M = 3;
List<BigDecimal> lowPrices = getLowPrices();
List<BigDecimal> highPrices = getHighPrices();
List<BigDecimal> closePrices = getClosePrices();
List<BigDecimal> lowV = calculateLowV(lowPrices, N);
List<BigDecimal> highV = calculateHighV(highPrices, N);
List<BigDecimal> rsv = calculateRSV(lowV, highV, closePrices);
List<BigDecimal> k = calculateK(rsv, M);
List<BigDecimal> d = calculateD(k, M);
System.out.println("SKDJ结果 K: " + k.get(k.size() - 1) + ", D: " + d.get(d.size() - 1));
}
public static List<BigDecimal> calculateLowV(List<BigDecimal> lowPrices, int N) {
List<BigDecimal> lowV = new ArrayList<>();
for (int i = 0; i < lowPrices.size(); i++) {
if (i < N - 1) {
lowV.add(null);
} else {
BigDecimal minLow = lowPrices.get(i);
for (int j = i - N + 1; j <= i; j++) {
BigDecimal currentLow = lowPrices.get(j);
if (currentLow.compareTo(minLow) < 0) {
minLow = currentLow;
}
}
lowV.add(minLow);
}
}
return lowV;
}
public static List<BigDecimal> calculateHighV(List<BigDecimal> highPrices, int N) {
List<BigDecimal> highV = new ArrayList<>();
for (int i = 0; i < highPrices.size(); i++) {
if (i < N - 1) {
highV.add(null);
} else {
BigDecimal maxHigh = highPrices.get(i);
for (int j = i - N + 1; j <= i; j++) {
BigDecimal currentHigh = highPrices.get(j);
if (currentHigh.compareTo(maxHigh) > 0) {
maxHigh = currentHigh;
}
}
highV.add(maxHigh);
}
}
return highV;
}
public static List<BigDecimal> calculateRSV(List<BigDecimal> lowV, List<BigDecimal> highV,
List<BigDecimal> closePrices) {
List<BigDecimal> rsv = new ArrayList<>();
for (int i = 0; i < closePrices.size(); i++) {
BigDecimal currentLowV = lowV.get(i);
BigDecimal currentHighV = highV.get(i);
BigDecimal currentClose = closePrices.get(i);
if (currentLowV != null && currentHighV != null) {
BigDecimal rsvValue = (currentClose.subtract(currentLowV))
.divide(currentHighV.subtract(currentLowV), 4, BigDecimal.ROUND_HALF_UP)
.multiply(BigDecimal.valueOf(100));
rsv.add(rsvValue);
} else {
rsv.add(null);
}
}
return rsv;
}
public static List<BigDecimal> calculateK(List<BigDecimal> rsv, int M) {
List<BigDecimal> k = new ArrayList<>();
for (int i = 0; i < rsv.size(); i++) {
if (i < M - 1)
.
