请老师帮我在出现零上金叉大于零时做个预警公式.如下图所示,谢谢! DIFF:EMA(CLOSE,12) - EMA(CLOSE,26); DEA:EMA(DIFF,9); MACD:2*(DIFF-DEA), COLORSTICK; WW:=DEA>REF(DEA,1); DD:=CROSS(DIFF,REF(DIFF,1)); 反身向上:WW AND DD,COLORFF00FF,LINETHICK2; 空中加油:IF(DIFF>0 AND DEA>0 AND CROSS(DIFF,DEA) AND MACD>REF(MACD,1),0.8,0)COLORRED,LINETHICK2; OZ:=COUNT(CROSS(DIFF,DEA) AND DIFF>0,BARSLAST(CROSS(DIFF,DEA) AND DIFFREF(DIFF,A1+1) AND CROSS(DIFF,DEA); STICKLINE(底背离,0,0.1,8,0),COLORRED; DRAWLINE(A1=0,DEA,底背离,DEA,0),COLORRED,LINETHICK2; A2:=BARSLAST(REF(CROSS(DEA,DIFF),1)); 顶背离:=REF(CLOSE,A2+1)DIFF AND CROSS(DEA,DIFF); DRAWLINE(A2=0,DEA,顶背离,DEA,0),COLORGREEN,LINETHICK2; DRAWICON(CROSS(DIFF,DEA),DEA,1);
爱约股解答：
DIFF:=EMA(CLOSE,12) - EMA(CLOSE,26);
DEA:=EMA(DIFF,9);
OZ:=COUNT(CROSS(DIFF,DEA) AND DIFF>0,BARSLAST(CROSS(DIFF,DEA) AND DIFF<0));
零上二金叉:CROSS(DIFF,DEA) AND OZ=1;
