易语言指标精度问题

1. 能否可以开启调背景色的功能,这黑色太黑了.费眼镜2.设置指标精度了为什么还有个点指标源码如下BACKGROUNDSTYLE(2);DIFF:EMA(CLOSE,SHORT)-EMA(CLOSE,LONG),COLORWHITE;DEA:EMA(DIFF,M),COLORYELLOW;MACD:(DIFF-DEA)*2,COLORSTICK;红面积:SUM(MACD,BARSLAST(MACD<0))*(MACD>0)*100,NODRAW,COLORRED;绿面积:SUM(MACD,BARSLAST(MACD>0))*(MACD<0)*100,NODRAW,COLORCYAN;X_2:=ROUND(REF(绿面积,1),2);X_3:=ROUND(REF(红面积,1),2);DRAWNUMBER(CROSS(0,MACD),HHV(REF(MACD,1),5)+0.03,ABS(X_3),0,COLORMAGENTA);DRAWNUMBER(CROSS(MACD,0),LLV(REF(MACD,1),5)-0.03,ABS(X_2),0,COLORGREEN);JC:=CROSS(DIFF,DEA);SC:=CROSSDOWN(DIFF,DEA);N1:=BARSLAST(JC) + 1;N2:=BARSLAST(SC) + 1;HH:=VALUEWHEN(CROSSDOWN(DIFF,DEA), HHV(H, N1));HH2:=VALUEWHEN(CROSSDOWN(DIFF,DEA),REF(HH,1));MHD:=VALUEWHEN(CROSSDOWN(DIFF,DEA),HHV(MACD,N1));MHD2:=VALUEWHEN(CROSSDOWN(DIFF,DEA),REF(MHD,1));LL:=VALUEWHEN(CROSS(DIFF,DEA), LLV(L, N2));LL2:=VALUEWHEN(CROSS(DIFF,DEA),REF(LL,1));MLD:=VALUEWHEN(CROSS(DIFF,DEA),LLV(MACD,N2));MLD2:=VALUEWHEN(CROSS(DIFF,DEA),REF(MLD,1));A:=CROSSDOWN(DIFF,DEA)&&HH>HH2&&MHD<MHD2;//顶背离B:=CROSS(DIFF,DEA)&&LL<LL2&&MLD>MLD2;//底背离DRAWTEXT(A, DIFF, \'顶背离\'),COLORGREEN;DRAWTEXT(B, DIFF, \'底背离\'),COLORRED;
