第一天陰線下跌3%為T1，第二天十字星，收盤在開盤正負1%內為T2，第三天陽線上漲3%為T3；

T1:= (REF(CLOSE,3)-REF(CLOSE,2))/REF(CLOSE,3)>0.03 AND REF(CLOSE,3)>REF(CLOSE,2) AND REF(O,2)>REF(CLOSE,2);

T21:= (REF(O,1)-REF(CLOSE,1))/REF(O,1)<0.01 AND REF(O,1)>REF(CLOSE,1);

T22:= (REF(CLOSE,1)-REF(O,1))/REF(CLOSE,1)<0.01 AND REF(O,1)<REF(CLOSE,1);

T2:=T21 OR T22;

T3:=(CLOSE-REF(CLOSE,1))/REF(CLOSE,1)>0.03 AND O<C;

T:T1 AND T2 AND T3;

D3代表前天，D2代表昨天，D1代表今天。選股公式為:

D3:= (REF(C,2)-REF(C,3))/REF(C,3)<0.97 ;

D2:= (REF(C,1)-REF(C,2))/REF(C,2)<1.01 AND (REF(C,1)-REF(C,2))/REF(C,2)>0.99 ;

D1:= C/REF(C,1)>1.03 ;

XG:D3 AND D2 AND D1
