{通达信MACD和KDJ组合指标公式}
{DIF快线、DEA慢线}
DIF:=EMA(CLOSE,12)-EMA(CLOSE,26);
DEA:=EMA(DIF,9);

{平滑KDJ，昨天介绍过}
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K1:=SMA(RSV,3,1);
D1:=SMA(K1,3,1);
K:=EMA(K1,5);
D:=EMA(D1,5);

MD:=DIF>DEA AND DIF<-0.5;{MACD的DIF大于DEA,并且DIF处于低位}

KJC:=CROSS(K,D);{KD金叉}
T:=BARSLAST(REF(KJC,1));{获得上次金叉的位置，为获取上次金叉的收盘价和K值做准备}
BL:=REF(C,T+1)>C AND REF(K,T+1)<K AND KJC AND D<50 AND COUNT(CROSS(K,30),T+1)>=1;
{收盘价与K值平替版背离，KD金叉，D值小于50，统计两次金叉之间有至少一次K值上穿30}

A1:=C>=REF(HHV(H,3),1) AND (C/REF(C,1)-1)*100>2 AND C>O AND COUNT(BL AND MD,15)=1;
{收盘价创三日新高，涨幅大于2%的阳线,最近15个周期中有一次KD背离并且DIF在DEA之上、DIF处于低位}
XG:FILTER(A1,15);
