编写条件：
选股公式如下： X1:=(C+L+H)/3; BB13:=ATAN(EMA(X1,13)-REF(EMA(X1,13),1))*3.1416*10; X2:=FILTER(BB13>1 AND EMA(X1,13)>REF(EMA(X1,8),1),10); X3:=CROSS(MACD.DIF,MACD.DEA); XG:X2 AND X3; 麻烦老师把MACD中DIF上穿DEA时， MACD的参数有12,26,9改成6,13，5编写方法：
DIF:=EMA(CLOSE,6)-EMA(CLOSE,13);
DEA:=EMA(DIF,5);
macd:=(DIF-DEA)*2;
X1:=(C+L+H)/3;
BB13:=ATAN(EMA(X1,13)-REF(EMA(X1,13),1))*3.1416*10;
X2:=FILTER(BB13>1 AND EMA(X1,13)>REF(EMA(X1,8),1),10);
X3:=crOSS(DIF,DEA);
XG:X2 AND X3;
