{☆背景设置}
DRAWGBK(C=C,COLORRGB(30,30,30),COLORRGB(130,130,130),1);
{☆买卖量计算}
AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));
买量:=IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE<OPEN,AA*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2)),LINETHICK0,COLORRED;
卖量:=IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-AA*(HIGH-LOW),0-VOL/2)),LINETHICK0,COLORCYAN;
日进出量:买量+卖量,LINETHICK0;
{☆画日进出量}
STICKLINE(日进出量<0,0,日进出量,4,0),COLORFF6600;

{☆画周、月净流入线}
周净流入:SUM(日进出量,5),LINETHICK2,COLORGREEN;
月净流入:SUM(日进出量,20),LINETHICK2;
{☆显示周、月翻红天数}
一周内翻红天:COUNT(日进出量>0,5),COLORYELLOW;
一月内翻红天:COUNT(日进出量>0,20),COLORMAGENTA;
{☆显示止损价位}
LC:=REF(CLOSE,1);
止损价位:(LC*1.0035*97+0.2)/99.65,COLORRED,LINETHICK0;
