上一個綠色macd的最低點，比上上一個macd的綠色最低點高，就定義為背離嗎？

參考：

DIFF : EMA(CLOSE,12) - EMA(CLOSE,26);
DEA  : EMA(DIFF,9);
MACD:2*(DIFF-DEA),COLORSTICK;
N1:=BARSLAST(CROSS(DIFF,DEA))+1;
N2:=BARSLAST(CROSSDOWN(DIFF,DEA))+1;
LL1:REF(LLV(MACD,N2),SUMBARS(N1=1,1)),NODRAW;
LL2:REF(LLV(MACD,N2),SUMBARS(N1=1,2)),NODRAW;
DRAWTEXT(CROSS(LL1>LL2,0.5),MACD,'背離');
