K线图我设置六百多数据，为什么提示indexOutException

好像是说只能设置三十多条？不是吧？

https://trans.chbtc.com/api/m/V1_7/ 代码里的数据api已经被弃掉，有知道现在要用哪个吗？

MACD算法公式：
（1）12日的EMA计算：EMA(12)=昨日EMA(12)×11 + c(今日)×2
13 13 13
（2）26日的EMA计算：EMA(26)=昨日EMA(26)×25 + c(今日)×2
27 27 27
（3）DIFF=EMA(12)-EMA(26)
（4）9日的DEA计算：DEA=昨日DEA×8 + 今日DIF×2
10 10
（5）MACD计算：MACD=（DIFF-DEA）×2

从后面往前面取值这种算法不是很可取，我认为的正确算法：
public class MACD {

private List<Double> DEAs;
private List<Double> DIFs;
private List<Double> BARs;

private List<Double> EMA12;
private List<Double> EMA26;
private EMAEntity mEMAEntity9;
private EMAEntity mEMAEntity12;
private EMAEntity mEMAEntity26;

public MACD(List<Float> OHLCData) {
 ......
    if (OHLCData != null && OHLCData.size() > 0) {

        for (int i = 0; i <= OHLCData.size() - 1; i++) {
            dIF = EMA12.get(i)-EMA26.get(i);
            if (i == 0) {
                dEA = 0+dIF*(2/10);
                mBAR = 0.0;
            } else {
                dEA = dEA*0.8 + dIF*0.2;
                mBAR = 2*(dIF-dEA);
            }
            dEAs.add(dEA);
            dIFs.add(dIF);
            mBARs.add(mBAR);
        }

            DEAs.addAll(dEAs);
            DIFs.addAll(dIFs);
            BARs.addAll(mBARs);
    }

......
}

public class EMAEntity {
private List EMAs;

public EMAEntity(List<MarketChartData> OHLCData, int n)
{
    EMAs = new ArrayList<Double>();
    if (OHLCData != null && OHLCData.size() > 0) {
        double close = 0;
        double EMA12 = 0.0;
        MarketChartData oHLCEntity;
        for (int i = 0; i <= OHLCData.size() - 1; i++) {
            close = OHLCData.get(i).getClosePrice();
            oHLCEntity = OHLCData.get(i);
            if (i ==0) {
                EMA12 = oHLCEntity.getClosePrice();
                EMAs.add(EMA12);
            }else
            {
                EMA12 = EMAs.get(EMAs.size()-1)*(n-1)/(n+1)+close*(2)/(n+1);
                EMAs.add(EMA12);
            }
        }

    }
}
public List<Double> getnEMA() {
    return EMAs;
}

}
