請問老師，二次金叉怎么表示？

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期與長周期的收盤價的指數平滑移動平均值做差。
DEA  : EMA(DIFF,M);//DIFF的M個周期指數平滑移動平均
2*(DIFF-DEA),COLORSTICK;//DIFF減DEA的2倍畫柱狀線
CROSS(DIFF,DEA),BPK;//DIFF上穿DEA,做多。
CROSS(DEA,DIFF),SPK;//DIFF下穿DEA,做空。
AUTOFILTER;

macd指標，0軸以下，形成兩次金叉后做多？

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期與長周期的收盤價的指數平滑移動平均值做差。
DEA  : EMA(DIFF,M);//DIFF的M個周期指數平滑移動平均
2*(DIFF-DEA),COLORSTICK;//DIFF減DEA的2倍畫柱狀線

N1:=BARSLAST(CROSS(0,DIFF))+1;

N2:=BARSLAST(CROSS(DIFF,0))+1;
CROSS(DIFF,DEA)&&COUNT(CROSS(DIFF,DEA),N1)=2,BPK;//DIFF上穿DEA,做多。
CROSS(DEA,DIFF)&&COUNT(CROSS(DEA,DIFF),N2)=2,SPK;//DIFF下穿DEA,做空。
