出现红箭头选股公式

编写要求：

Z:=(HHV(H,3)+LLV(L,3))/2;A:=IF(C>ZZ,VOL,0);B:=IF(C=0,0,BBD,3,0),COLOR000088; STICKLINE(BBD>=0,0,BBD,1.5,0),COLOR0000AA; STICKLINE(BBD>=0,0,BBD,1,0),COLOR0000CC; STICKLINE(BBD>=0,0,BBD,0.5,0),COLOR0000FF; STICKLINE(BBD<0,0,BBD,3,0),COLOR888800; STICKLINE(BBD<0,0,BBD,1.5,0),COLORAAAA00; STICKLINE(BBD<0,0,BBD,1,0),COLORCCCC00; STICKLINE(BBD<0,0,BBD,0.5,0),COLORFFFF00; XH1:=REF(BBD,1)REF(BBD,1) AND BBD>0; XH2:=REF(BBD,1)>=REF(BBD,2) AND REF(BBD,1)>8 AND BBD

解答：

?ZZ:=(HHV(H,3)+LLV(L,3))/2;A:=IF(C>ZZ,VOL,0);B:=IF(C

BBD:=EMA(总0,3)/SUM(VOL,5)*100;
