把“优化MACD” 造成选股预警

希望老师能把BIAS2线下穿BIAS4线 BIAS2线上穿BIAS4线 分别做出预警公式。多谢！ 代码如下： BIAS1 : (CLOSE-MA(CLOSE,6))/MA(CLOSE,6)*100; BIAS2 : (CLOSE-MA(CLOSE,12))/MA(CLOSE,12)*100; BIAS3 : (CLOSE-MA(CLOSE,24))/MA(CLOSE,24)*100; BIAS4 : BIAS3-BIAS1,LINETHICK3; 2;-2;10;-10; DRAWGBKLAST(CLOSE>OPEN,STRIP(RGB(25,0,0),RGB(0,25,0),0));

爱约股解答：

BIAS1 := (CLOSE-MA(CLOSE,6))/MA(CLOSE,6)*100; 

BIAS2 := (CLOSE-MA(CLOSE,12))/MA(CLOSE,12)*100; 

BIAS3 := (CLOSE-MA(CLOSE,24))/MA(CLOSE,24)*100; 

BIAS4 := BIAS3-BIAS1;

上穿:CROSS(BIAS2,BIAS4);

下穿:CROSS(BIAS2,BIAS4);
