买入线指标出现红箭头时的选股公式

编写条件：

DIF1:=EMA(DCLOSE,12)-EMA(DCLOSE,26); DEA1:=EMA(DIF1,9); {柱状线} AAA1:=(DIF1-DEA1)*2*60; AAA涨:IF(AAA1>REF(AAA1,1),AAA1,DRAWNULL), STICK,COLORRED,LINETHICK1; AAA跌:IF(AAA1编写方法：

 DIF1:=EMA(DCLOSE,12)-EMA(DCLOSE,26);

 DEA1:=EMA(DIF1,9);

 {柱状线}

 AAA1:=(DIF1-DEA1)*2*60;

 AAA上:=IF(AAA1>REF(AAA1,1),AAA1,DRAWNULL);

 AAA下:=IF(AAA1<REF(AAA1,1),AAA1,DRAWNULL);

 买入线:=15;

 房子:=AAA1-REF(AAA1,1),COLORRED;

 XG:crOSS(房子,买入线);
