Answer 1

可以修改通达信公式主力线上穿50为买,下穿80为卖的选股公式,但你提供的公式提示错误,无法正常运行应该是缺少代码

如果要是没猜错的话选股效果应该如下图，上穿买选股位置为白色尖所指，下穿卖选股位置为黄色尖所指。

DRAWTEXT(CROSS(主力线,50),H,'买入');

DRAWTEXT(CROSS(80,主力线),H,'卖出');

VAR2赋值:33日内最低价的最低值

VAR3赋值:21日内最高价的最高值

VAR4赋值:(收盘价-VAR2)/(VAR3-VAR2)*100的20日指数移动平均*0.998

100,STICK,线宽为7, COLORFFCC33

80, STICK,线宽为7, COLORFF9933

50,STICK,线宽为7, 画蓝色

20,STICK,线宽为7,COLORCC0033

20,画白色

50,画黄色

80,画青色

当满足条件收盘价>0的25日过滤时,在10位置书写文字,, 画白色

当满足条件收盘价>0的25日过滤时,在30位置书写文字, , 画白色

当满足条件收盘价>0的25日过滤时,在65位置书写文字, , 画白色

当满足条件收盘价>0的25日过滤时,在88位置书写文字, , 画白色

当前安全度赋值:100-0.667*1日前的VAR4+0.333*VAR4的1日指数移动平均,线宽为2 ,画红色

A赋值:-100*(34日内最高价的最高值-收盘价)/(34日内最高价的最高值-34日内最低价的最低值)的19日简单移动平均,画红色

B赋值:-100*(14日内最高价的最高值-收盘价)/(14日内最高价的最高值-14日内最低价的最低值)

D赋值:-100*(34日内最高价的最高值-收盘价)/(34日内最高价的最高值-34日内最低价的最低值)的4日指数移动平均,线宽为2

长庄线赋值:A+100,画洋红色

游资线赋值:B+100,画黄色,线宽为2

输出主力线:D+100,画红色,线宽为4

当满足条件主力线上穿50时,在最高价位置书写文字

当满足条件80上穿主力线时,在最高价位置书写文字
