DEA:=EMA(DIFF,9),COLORFFFF00;
MACD:=(DIFF-DEA)*2;
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
A2:=BARSLAST(REF(CROSS(DEA,DIFF),1));
底背离:REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA);
选股二：（其实就是把第一个选股公式的DCLOSE改为了CLOSE）
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
A1:=BARSLAST(REF(CROSS(DIFF,DEA),1));
B1:=REF(C,A1+1)>C AND REF(DIFF,A1+1)
FILTER(B1>0,5)
选股三：
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
AB:=REF(DEA,20);
BB:=REF(CLOSE,30);
低值:=LLV(DEA,25);
选股:CROSS("KDJ.J","KDJ.D")AND "KDJ.D"<30 AND DEA>AB AND DEA>低值 AND CLOSE<-0.2;

(注意包含了DCLOSE函数，是个移动函数，但是和普通的未来函数有区别)
