DRAWICON(CROSS(VAR3,VAR60),60,1);

=======================

预警公式

VAR3:=((3)*(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1)) - (2)*(SMA(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1),3,1)));
VAR60:=60;
牛股线:CROSS(VAR3,VAR60);

预警公式也可这样：

VAR3:=((3)*(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1)) - (2)*(SMA(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1),3,1)));
牛股线:CROSS(VAR3,60);
