网友求助：
编7日均线14日均线上行的同时趋势线上穿0的选股公式，谢谢！
大智慧趋势线指标公式如下：（同花顺测试通过，见附图）
DRAWGBKLAST(CLOSE>0,STRIP(RGB(95,95,95),RGB(0,0,0),0));
ZF:=(C/REF(C,1)-1)*100;
趋势:SUM(ZF,3),COLORFFFFFF,LINETHICK2;
超涨:IF(MA(ZF,3)>=5,15,0),COLOR0000FF;
WK:=趋势=LLV(趋势,4) AND 趋势-HHV(趋势,4)<=0-20 AND HHV(趋势,4)>=8;
挖坑:IF(WK,0-10,0),COLOR00FFFF;
超跌:IF(MA(ZF,3)<=0-5,0-15,0),COLOR00FF00;
CZSJ:=BARSLAST(超涨=15);
CDSJ:=BARSLAST(超跌=0-15);
CZQY:=CZSJ<=8 AND CZSJ<=CDSJ AND COUNT(MA(趋势,3)>=0-5,CZSJ)=CZSJ;
CDQY:=CDSJ<=8 AND CDSJ<=CZSJ AND COUNT(MA(趋势,3)<=5,CDSJ)=CDSJ;
关注期:IF(CZQY,CZSJ+1,0),COLORFF00FF,POINTDOT;
跟踪期:IF(CDQY,0-CDSJ-1,0),COLORFF8800,POINTDOT;
解答如下：
ZF:=(C/REF(C,1)-1)*100;
趋势:=SUM(ZF,3);
SELECT=MA(C,7)>REF(MA(C,7),1) AND MA(C,14)>REF(MA(C,14),1) AND CROSS(趋势,0);
