公式一 低吸
RSV4:=(CLOSE-LLV(LOW,36))/(HHV(HIGH,36)-LLV(LOW,36))*100;
RSV5:=MA((LLV(LOW,45)-CLOSE)/(HHV(HIGH,45)-LLV(LOW,45))*100,5);
K4:=SMA(RSV4,3,1);
D4:=SMA(K4,3,1);
J4:=3*K4-2*D4;
CK4:=MA(K4,15);
CD4:=MA(D4,15);
CJ4:=MA(J4,15);
JJ1:=CJ4>REF(CJ4,1);
低吸XG:CROSS(-5,RSV5) AND JJ1;
公式二 三底背离
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)<DIFF AND CROSS(DIFF,DEA);
A2:=BARSLAST(REF(CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3)),1));
B2:=REF(C,A2+1)>C AND REF("KDJ.K"(9,3,3),A2+1)<"KDJ.K"(9,3,3) AND CROSS("KDJ.K"(9,3,3),"KDJ.D"(9,3,3));
A3:=BARSLAST(REF(CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24)),1));
B3:=REF(C,A3+1)>C AND REF("RSI.RSI1"(6,12,24),A3+1)<"RSI.RSI1"(6,12,24) AND CROSS("RSI.RSI1"(6,12,24),"RSI.RSI2"(6,12,24));
三底背离:B1>0 OR B2>0 OR B3>0;
公式三 趋势见底
趋势:=3*SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1)-2*SMA(SMA((CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100,5,1),3,1);
见底:=10;
短期底部:=CROSS(趋势,见底);
RR8:=MA(CLOSE,27);
RR9:=(CLOSE-RR8)/RR8*100;
RRA:=MA(RR9,2);
RRB:=BARSLAST(CROSS(-10,RRA)=1);
RRD:=RRA<-10 AND RRB>3;
趋势见底:RRD AND 短期底部;
