那位老师帮忙(出现红色箭头(明月照积雪)时)改预警选股

编写要求：

RV:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100; RG:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100; J0:=(HIGH+LOW)/2; QJ:=EMA(J0,3); J1:=IF(CLOSE>QJ,VOL,0); J2:=IF(CLOSE0,100,50,3,0),COLOR990099; STICKLINE(VAR3VAR5,VAR5,VAR4,2,0),COLOR0000BB; DRAWICON(CROSS(VAR4,VAR5) AND VAR530,97,2); 明月照积雪:CROSS(VAR4,VAR5) AND CROSS(KK,DD),NODRAW,COLORMAGENTA; 买:CROSS(VAR4,VAR5) AND VAR5

股票网解答：

RV:=(CLOSE-LLV(LOW,27))/(HHV(HIGH,27)-LLV(LOW,27))*100;

VAR4:=SMA(RV,3,1);

VAR5:=SMA(VAR4,3,1);

CROSS(VAR4,VAR5) AND VAR5<30;
