“反转”预警公式

编写要求：

写出现红箭头时的“反转”预警公式： P13:MA(C,13),COLORWHITE; 止赢:P13*1.1,COLORRED; 短炒:P13*0.9,COLORGREEN; HSL:=100*VOL/CAPITAL; 年换手:SUM(HSL,250),NODRAW,COLORRED; K值:=100*(H/MIN(L,REF(C,1))-1); K年:MA(K值*K值,250),NODRAW,COLOR00FFFF; K季:MA(K值*K值,60),NODRAW,COLOR00DDFF; K15:MA(K值*K值,15),NODRAW,COLOR00BBFF; VAR8:=VOL>2*MA(VOL,30); VAR9:="DMI.ADX"(12,6); VARA:="DMI.ADXR"(12,6); VARB:=CLOSE>MA(CLOSE,30) AND CLOSEREF(MA(CLOSE,30),1); VARD:=BARSLAST(CROSS(MA(CLOSE,5),MA(CLOSE,10)))

解答：

?反转:=TROUGHBARS(3,15,1)<4;

FILTER(反转=1,3);
