一个通达信老公式 但很经典

买:=IF("KDJ.J"<0,10,0);
条件:=CROSS(9.9,买);
VAR1:=(2*CLOSE+HIGH+LOW)/4;
 VAR2:=LLV(LOW,5);
 VAR3:=HHV(HIGH,5);
 VAR4:=EMA((VAR1-VAR2)/(VAR3-VAR2)*100,5);
 MA1:=MA(VAR4,2);
 AA:STICKLINE(VAR4>MA1,VAR4,MA1,6,1),COLORRED;
 BBB:STICKLINE(VAR4>MA1 AND REF(VAR4,1)<30,VAR4,MA1,6,1),COLORRED;
 STICKLINE(VAR4<=MA1,VAR4,MA1,6,1),COLORFFCC66;
 DRAWICON(CROSS(9.9,买),VAR4-12,4);
 STICKLINE(CROSS(9.9,买),VAR4+5,MA1-4,6,1),COLORYELLOW;
 XXX:STICKLINE(VAR4>MA1 AND REF(VAR4,1)<30,VAR4+5,MA1-4,6,1),COLORYELLOW;
