Straight flush "right" source code (vice), changed to the formula used by Master Boyi. . Is there a master to help?

DIFF:=EMA (closing, 12)-EMA (closing, 27);

DEA:=EMA(DIFF，9)；

● Golden fork: = cross (diff, DEA) and diff.

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

Quadratic golden fork: = cross (diff, DEA) and DEA < 0 AND COUNT(JCCOUNT=2 = 2,21) =1;

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

Bottom deviation: = ref (close, a1+1) > close and diff > REF(DIFF, A 1+ 1) and CROSS(DIFF, DEA);

● The gold fork and the secondary gold fork deviate from the bottom;
