MACD神物之底部钝化选股指标公式

DIF:=100*(EMA(CLOSE,12)-EMA(CLOSE,26));

DEA:=EMA(DIF,9);

死叉:=crOSS(DEA,DIF);

N1:=BArslAst(死叉);{最近一次死叉的位置}

N2:=REF(BARSLAST(死叉),N1+1);{倒数第二次死叉与倒数第一次死叉的区间}

N3:=REF(BARSLAST(死叉),N2+N1+2);{倒数第三次死叉与倒数第二次死叉的区间}

CL1:=LLV(C,N1+1);{最近一次死叉后，最低收盘价}

DIFL1:=LLV(DIF,N1+1);

CL2:=REF(CL1,N1+1);{倒数第二次死叉与倒数第一次死叉之间的最低收盘价}

DIFL2:=REF(DIFL1,N1+1);

CL3:=REF(CL2,N1+1);{倒数第三次死叉与倒数第二次死叉之间的最低收盘价}

DIFL3:=REF(DIFL2,N1+1);

pdiFL2:=IF(DIFL2>0,INTPART(LOG(DIFL2))-1,INTPART(LOG(-DIFL2))-1);

mdiFL2:=INTPART(DIFL2/POW(10,PDIFL2));

PDIFL3:=IF(DIFL3>0,INTPART(LOG(DIFL3))-1,INTPART(LOG(-DIFL3))-1);

MDIFL3:=INTPART(DIFL3/POW(10,PDIFL3));

MDIFB2:=INTPART(DIF/POW(10,PDIFL2));

MDIFB3:=INTPART(DIF/POW(10,PDIFL3));

直接底背离:=(CL1<CL2 ) AND (MDIFB2>MDIFL2) AND (macd<0 AND REF(MacD,1)<0) AND MDIFB2<=REF(MDIFB2,1);

隔峰底背离:=(CL1<CL3 AND CL3<CL2 ) AND (MDIFB3>MDIFL3) AND (MACD<0 AND REF(MACD,1)<0) AND MDIFB3<=REF(MDIFB3,1);

底部钝化:直接底背离 OR 隔峰底背离;
