老师能把我自己改的这个macd 改成选股公式吗？要求：最近几天内白线上穿蓝线，变黄线，出现建仓

DIFF:EMA(CLOSE,9)-EMA(CLOSE,17);
DEA:EMA(DIFF,8),COLOrffaa00;
MACD:=2*(DIFF-DEA);
STICKLINE(MACD>=0,MACD,0,4,1),COLORF00FF0;
STICKLINE(MACD<0,MACD,0,4,1),colorwhite;
STICKLINE(MACD0,0,MACD,4,0 ),COLOR00aaff;
建仓:IF(DIFF<0,DIFF,0),coloryellow,LINETHICK2;
加仓:IF(DIFF<0,0,DIFF),colorred,LINETHICK2;
白线破仓:IF(DIFF 趋势强弱:IF(DIFF>DEA,DEA,DEA),COLORFF937F,LINETHICK2;
X1:IF(diff<0,diff,0),COLOR0000FF,LINETHICK2;
X2:IF(diff<0,0,diff),colormagenta,LINETHICK1;
X3:IF(diff X4:IF(diff>dea,dea,dea),linethick1,COLORffbb11;
低位金叉:=CROSS(DIFF,DEA) AND DIFF<-0.1;
STICKLINE(低位金叉,DEA*0.86,DEA*0.66,6,0),coloryellow;
DRAWTEXT(低位金叉,dea*0.86,' 低位金叉'),coloryellow;
JCCOUNT:=COUNT(CROSS(DIFF,DEA),BARSLAST(DEA>=0));
二次金叉:=CROSS(DIFF,DEA) AND DEA<0 AND COUNT(JCCOUNT=2,21)=1;
STICKLINE(二次金叉,DEA*0.96,DEA*0.76,6,0),ColorFF00FF;
DRAWICON(二次金叉,dea*1.1,'BUY') ;
DRAWTEXT(二次金叉,DEA*0.96,' 二次金叉'),ColorFF00FF;
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
底背离:=REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);
STICKLINE(底背离,DEA*1.09,DEA*0.86,6,0),Color00FF00;
DRAWLINE(A1=0,DEA,底背离,DEA,0),colorred,linethick1;
DRAWTEXT(底背离,DEA*1.09,' 底背离'),Color6600FF;
A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));
顶背离:=REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF);
DRAWLINE(A2=0,DEA,顶背离,DEA,0),colorgreen,linethick1;
DRAWTEXT(顶背离,DEA*1.2,' 顶背离'),Color00FF00

也就是说，在macd 线上最近几天出现黄线的，能选的出来吗？？

是低位金叉吗？

DIFF:=EMA(CLOSE,9)-EMA(CLOSE,17);
DEA:=EMA(DIFF,8),COLORFFAA00;
MACD:=2*(DIFF-DEA);
低位金叉:CROSS(DIFF,DEA) AND DIFF<-0.1;

我也不确定，还是看看专业人士怎么说。
