Z:=MA(C,120);
VAR3:=(MA(C,5)-Z)/Z;
VAR4:=MA((CLOSE-LLV(LOW,20))/(HHV(HIGH,20)-LLV(LOW,20))*100,3);
D1:DRAWTEXT(CLOSE>Z AND REF(VAR4,1)<30 AND VAR4>REF(VAR4,1) AND REF(VAR4,1)<REF(VAR4,2) ,0.99*LOW ,'★B'),COLORRED;
D2:DRAWTEXT(REF(VAR4,1)<7 AND VAR4>REF(VAR4,1) AND REF(VAR4,1)<REF(VAR4,2) AND VAR3<-0.1,0.99*LOW ,'★B'),COLORGREEN;
D3:DRAWTEXT(CROSS(VAR4,5) AND VAR3<-0.3,0.99*LOW ,'★B'),COLORBLUE;
