编写要求：
OBV:=EMA(SUM(IF(C>REF(C,1),VOL,IF(C=REF(DIFF,1) AND DEA>=REF(DEA,1)),LINETHICK4,Color0089FF;{//橙}
FILLRGN(DIFF,DEA,DIFF>=DEA),Color0089FF;{//橙--加宽}
PARTLINE(DIFF,DIFF<=REF(DIFF,1) AND DEA<=REF(DEA,1)),LINETHICK4,COLORBLUE;{//蓝21}
FILLRGN(DIFF,DEA,DIFF<=DEA),COLORBLUE;{//蓝--加宽}
PARTLINE(DIFF,DIFF>=REF(DIFF,1) AND DEA<=REF(DEA,1)),LINETHICK4,Color00C500;{//绿}
PARTLINE(DIFF,DIFF<=REF(DIFF,1) AND DEA>=REF(DEA,1)),LINETHICK4,COLORYELLOW;{//黄}
STICKLINE(MACD>ref(MACD,1) and MACD>0,0,MACD,2,0),COLORRED;
STICKLINE(MACD0,0,MACD,2,0),COLORYELLOW;
STICKLINE(MACDref(MACD,1) and MACD<0,0,MACD,2,0),COLOR0099FF;
PARTLINE(2*(DEA-DIFF),C),LINETHICK2,COLORGRAY;{//加速线}
解答：
?OBV:=EMA(SUM(IF(C>REF(C,1),VOL,IF(C
OBVE:=EMA(OBV,3);
