君山股道的同学们都知道“红色星期三”
“黑色星期一”等术语，但是事实上每段行情的规律都不一样的，所以要经常去统计。我写了一个简单的指标，就是辅助用来统计每个周一、周二、周三等的涨幅。
通达信版本：
星期一:SUM(IF((WEEKDAY==1),C-REF(C,1),0),N1);
贰:SUM(IF((WEEKDAY==2),C-REF(C,1),0),N1);
叁:SUM(IF((WEEKDAY==3),C-REF(C,1),0),N1);
四:SUM(IF((WEEKDAY==4),C-REF(C,1),0),N1);
五:SUM(IF((WEEKDAY==5),C-REF(C,1),0),N1);
其中N1 取 5-1000，默认55
文华财经版本：
W1:SUM (IFELSE((WEEKDAY=1),C-REF(C,1),0),N1);
W2:SUM (IFELSE((WEEKDAY=2),C-REF(C,1),0),N1);
W3:SUM(IFELSE((WEEKDAY=3),C-REF(C,1),0),N1);
W4:SUM(IFELSE((WEEKDAY=4),C-REF(C,1),0),N1);
W5:SUM(IFELSE((WEEKDAY=5),C-REF(C,1),0),N1);
其中N1 取 5-1000，默认55
统计的时候，根据想统计的交易天数，设置N1参数的数值。这样我们就能知道任意股票、大盘、商品、股指期货的星期几涨跌统计了。
7.29 版本1.1 更新：
前5个数据为某日（比如星期一）的涨跌点数，后5个数据为某日的收阳的概率
通达信版本：
周壹:SUM(IF((WEEKDAY==1),C-REF(C,1),0),N1);
周贰:SUM(IF((WEEKDAY==2),C-REF(C,1),0),N1);
周叁:SUM(IF((WEEKDAY==3),C-REF(C,1),0),N1);
周肆:SUM(IF((WEEKDAY==4),C-REF(C,1),0),N1);
周伍:SUM(IF((WEEKDAY==5),C-REF(C,1),0),N1);
周一:SUM(IF((WEEKDAY==1)AND
(C-O)>0,1,0),N1)/SUM(IF((WEEKDAY==1),1,0),N1),NODRAW;
周二:SUM(IF((WEEKDAY==2)AND
(C-O)>0,1,0),N1)/SUM(IF((WEEKDAY==2),1,0),N1),NODRAW;
周三:SUM(IF((WEEKDAY==3)AND
(C-O)>0,1,0),N1)/SUM(IF((WEEKDAY==3),1,0),N1),NODRAW;
周四:SUM(IF((WEEKDAY==4)AND
(C-O)>0,1,0),N1)/SUM(IF((WEEKDAY==4),1,0),N1),NODRAW;
周五:SUM(IF((WEEKDAY==5)AND
(C-O)>0,1,0),N1)/SUM(IF((WEEKDAY==5),1,0),N1),NODRAW;
其中N1 取 5-1000，默认55

W4:SUM(IFELSE((WEEKDAY=4),C-REF(C,1),0),N1);
W5:SUM(IFELSE((WEEKDAY=5),C-REF(C,1),0),N1);
1:SUM(IFELSE(((WEEKDAY=1) AND
(C-O)>0),1,0),N1)/SUM(IFELSE((WEEKDAY=1),1,0),N1);
2:SUM(IFELSE((WEEKDAY=2) AND
(C-O)>0,1,0),N1)/SUM(IFELSE((WEEKDAY=2),1,0),N1);
3:SUM(IFELSE((WEEKDAY=3) AND
