变态KDJ底部之红箭头选股指标公式

VAR1:=(H+L+O+C*2)/5;
VAR4:=EMA(VAR1,2);
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:=expma(EXPMA(EXPMA(RSV,2),3),3);
D:=SMA(K,2,1);
J:=3.5*K-2*D;
红箭头:FILTER(J>REF(J,1)AND J AND JREF(VAR4,1)
AND K>=REF(K,1)AND J<40
OR crOSS(J,K)AND CROSS(J,D)
AND J<40 OR J>REF(J,1)AND J<40,7);
