{小周期}
DIF3_6.5F:=(EMA(CLOSE,3)-(EMA(CLOSE,6)+EMA(CLOSE,7))/2);
DEA3_6.5F:=(EMA(DIF3_6.5F,3)+EMA(DIF3_6.5,2));
DRAWBAND(DEA3_6.5F,RGB(100,100,300),DIF3_6.5F,RGB(100,300,150));
解答如下：
DIF3_6.5F:=(EMA(CLOSE,3)-(EMA(CLOSE,6)+EMA(CLOSE,7))/2);
DEA3_6.5F:=(EMA(DIF3_6.5F,3)+EMA(DIF3_6.5,2));
XG:CROSS(DIF3_6.5F,DEA3_6.5F);
