N:=7;
DIF3_6.5F:=(EMA(CLOSE,3)-(EMA(CLOSE,6)+EMA(CLOSE,7))/2);
DEA3_6.5F:=(EMA(DIF3_6.5F,3)+EMA(DIF3_6.5F,2));
AA2:=REF(DIF3_6.5F,N)=LLV(DIF3_6.5F,2*N+1);
BB2:=BACKSET(AA2,N+1);
CC2:=FILTER(BB2,N) AND DIF3_6.5F=LLV(DIF3_6.5F,N+1);
A2:=BARSLAST(REF(CC2,1));
底背离:REF(CLOSE,A2+1)>CLOSE AND REF(DIF3_6.5F,A2+1)<DIF3_6.5F AND CC2;
 
 
解答如下：
N:=7;
DIF3_:=(EMA(CLOSE,3)-(EMA(CLOSE,6)+EMA(CLOSE,7))/2);
DEA3_:=(EMA(DIF3_,3)+EMA(DIF3_,2));
AA2:=REF(DIF3_,N)=LLV(DIF3_,2*N+1);
BB2:=BACKSET(AA2,N+1);
CC2:=FILTER(BB2,N) AND DIF3_=LLV(DIF3_,N+1);
A2:=BARSLAST(REF(CC2,1));
底背离:REF(CLOSE,A2+1)>CLOSE AND REF(DIF3_,A2+1)<DIF3_ AND CC2;
