网友求助：
请老师帮忙把幅图中的信号修改成选股公式
源码
Var11aa:=EMA(CLOSE,30)-EMA(CLOSE,17);
Var12aa:=EMA(Var11aa,5);
九:=TROUGHBARS(3,10,1)<1 AND CROSS(Var11aa,Var12aa);
DRAWICON(九>0,8,1 );
drawtext(九,99,'九'),color000000;
Var2a:=(EMA(CLOSE,26)-EMA(CLOSE,52))/MA(CLOSE,60)*100;
Var3a:=EMA(Var2a,18);
Var4a:=Var2a<-1;
Var5a:=Var4a AND CROSS(Var2a,Var3a);
追2:=Var5a;
追涨C:=if(追2>0,0.8,0) ;
xx:=EMA(CLOSE,30)-EMA(CLOSE,17);
yy:=EMA(xx,13);
短针2:=TROUGHBARS(3,5,1)<1 AND xx<YY;
阴:=if(短针2>0,0.4,0);
DRAWICON(阴>0,8,1 );
drawtext(阴,85,'阴'),color000000;
n1:=30;n2:=17;n3:=5;n4:=6;
Var1x:=EMA(CLOSE,N1)-EMA(CLOSE,N2);
Var2x:=EMA(Var1x,N3);
剑:=CROSS(Var1x,Var2x) AND TROUGHBARS(3,7,1)<1;
DRAWICON(剑>0,8,1 );
drawtext(剑,73,'剑'),color000000;
阴剑: 九 or 剑 or 阴;
解答如下：
{未来函数，不建议使用}
xx:=EMA(CLOSE,30)-EMA(CLOSE,17);
yy:=EMA(xx,13);
短针2:=TROUGHBARS(3,5,1)<1 AND xx<YY;
阴:=if(短针2>0,0.4,0);
n1:=30;n2:=17;n3:=5;n4:=6;
Var1x:=EMA(CLOSE,N1)-EMA(CLOSE,N2);
Var2x:=EMA(Var1x,N3);
剑:=CROSS(Var1x,Var2x) AND TROUGHBARS(3,7,1)<1;
Var11aa:=EMA(CLOSE,30)-EMA(CLOSE,17);
Var12aa:=EMA(Var11aa,5);
九:=TROUGHBARS(3,10,1)<1 AND CROSS(Var11aa,Var12aa);
阴>0 OR 剑>0 OR 九>0;
