同花順“右側”源碼(vice)，改成博壹大師用的公式。。有高手幫忙嗎？

DEA:=EMA(DIFF，9)；

●金叉:= cross (diff，DEA)和diff

JCCOUNT:=COUNT(CROSS(DIFF，DEA)，bars last(DEA & gt；=0));

二次金叉:= cross (diff，DEA) and DEA < 0 AND COUNT(JCCOUNT=2，21)= 1；

a 1:= bars last(REF(CROSS(DIFF，DEA)，1))；

底部偏差:= ref (close，a 1+1)> CLOSE AND DIFF & gt；REF(DIFF，A1+1)和CROSS(DIFF，DEA)；

●金叉和二級金叉與底部背離；
