请问老师，二次金叉怎么表示？　[文华财经]

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期与长周期的收盘价的指数平滑移动平均值做差。
DEA  : EMA(DIFF,M);//DIFF的M个周期指数平滑移动平均
2*(DIFF-DEA),COLORSTICK;//DIFF减DEA的2倍画柱状线
CROSS(DIFF,DEA),BPK;//DIFF上穿DEA,做多。
CROSS(DEA,DIFF),SPK;//DIFF下穿DEA,做空。

macd指标，0轴以下，形成两次金叉后做多？

DIFF : EMA(CLOSE,SHORT) - EMA(CLOSE,LONG);//短周期与长周期的收盘价的指数平滑移动平均值做差。
DEA  : EMA(DIFF,M);//DIFF的M个周期指数平滑移动平均
2*(DIFF-DEA),COLORSTICK;//DIFF减DEA的2倍画柱状线

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。
