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 80,90,'★'),COLORRED; DRAWTEXT(K0 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;

股票网解答：

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

K:=SMA(RSV,M1,1);

XG:K<20;
