编写条件：
求:A 30MA均线大于,或等于45度角向上,K线回探30MA(包括接近,回踩,下探后收在30MA附近)的选股公式. B:在主图中当30MA大于,或等于45度角向上时为红色;当30MA均线小于45度向上时为黄色;当30MA向下时为绿色.编写方法：
M30:MA(C,30),COLOR00FFFF,LINETHICK3;
JD:=ATAN((MA(C,30)/REF(MA(C,30),1)-1)*100)*180/3.14159;
IF(JD>=45,M30,DRAWNULL)COLORRED,LINETHICK3;
IF(MA(C,30)<REF(MA(C,30),1),M30,DRAWNULL)COLORGREEN,LINETHICK3;
JD:=ATAN((MA(C,30)/REF(MA(C,30),1)-1)*100)*180/3.14159;
JD>=45 AND V<REF(V,1) AND BETWEEN(C/MA(C,30),1.010,1.100);
