底部顶部结构之直接底背离选股指标公式

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

DEA:=EMA(DIF,9);

死叉:=crOSS(DEA,DIF);

N1:=BArslAst(死叉);

CL1:=LLV(C,N1+1);

CL2:=REF(CL1,N1+1);

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

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

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);
