要求：红线上穿绿线预警 谢谢。

VAR1:=(CLOSE+HIGH+LOW)/3;
VAR2:=EMA(VAR1,10);
VAR3:=REF(VAR2,1);
绿探底震仓:IF(VAR2,10,DRAWNULL),COLORGREEN,LINETHICK9;
红买: IF(VAR2>VAR3,10,DRAWNULL), COLORRED,LINETHICK9;
蓝卖: IF(VAR2<VAR3,10,DRAWNULL),COLORFFFF00,LINETHICK9;
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
上穿买:SMA(RSV,3,1),COLORRED;
下穿卖:SMA(上穿买,3,1),COLORFFFF00;

解答如下：

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
上穿买:=SMA(RSV,3,1);
下穿卖:=SMA(上穿买,3,1);
预警:CROSS(上穿买,下穿卖);
