大单比率简单明了，不用多说一看就知。源码如下：

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;

进出量:=买量+卖量,COLOR00FFFF;

STICKLINE(进出量<0,0,进出量,4,0),COLORFF6600;

STICKLINE(进出量<0,0,进出量,3,0),COLORFF9900;

STICKLINE(进出量<0,0,进出量,1.5,0),COLORFFCC00;

N:=5; M:=13; N日内净流入:SUM(进出量,N),LINETHICK2,COLORGREEN;

流入:IF(N日内净流入>REF(N日内净流入,1),N日内净流入,DRAWNULL),COLORRED,LINETHICK2;

连红天:BARSLASTCOUNT(进出量>0);

M日内翻红天:COUNT(进出量>0,M),COLORRED;

走熊天:BARSLASTCOUNT(N日内净流入<0),COLORCYAN;

走牛天:BARSLASTCOUNT(N日内净流入>0),COLORRED;

强势天:BARSLASTCOUNT((N日内净流入>REF(N日内净流入,1))>0 AND N日内净流入>0);

弱势天:BARSLASTCOUNT((N日内净流入<REF(N日内净流入,1))>0 AND N日内净流入<0);
