编写要求：

请老师把kd指标中当天出现'●' 的-做出预警RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;K:SMA(RSV,M1,1),LINETHICK1;D:SMA(K,M2,1),LINETHICK1;乖离:(K-D),COLORSTICK;STICKLINE(乖离 > 0,乖离,0,2.3,0),COLOR0000FF;STICKLINE(乖离 < 0,乖离,0,2.3,0),COLORFF4242;DRAWTEXT(K>80,90,'★'),COLORRED;DRAWTEXT(K<20,-5,'●'),COLORYELLOW;DRAWTEXT(CROSS(80,K),80,'逃'),COLORYELLOW;DRAWTEXT(CROSS(K,20),20,'▲'),COLORYELLOW;DRAWTEXT(CROSS(K,D),D,'▲'),COLORYELLOW;买进:(CROSS(K,D)AND (MA(C,18)-MA(C,50))>0 AND VOL>REF(VOL,1)*1.9 AND MA(C,50)>REF(MA(C,50),1))*10;卖出:(CROSS(80,K))*5;DRAWTEXT(CROSS(80,K),80,'逃'),COLORYELLOW;DRAWTEXT(CROSS(K,D)AND VOL>REF(VOL,1)*1.5 AND MA(C,50)>REF(MA(C,50),1),0,'▲'),COLORYELLOW;

解答：

RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
