尝试在每日开盘时绘制水平射线，我的代码由于某种原因没有绘制任何内容

//@version=4
study("Opens +", overlay=true)
higherTF1 = input("D", type=input.resolution)

dailyopen = security(syminfo.tickerid, higherTF1, open)

var line1 = line.new(bar_index, dailyopen,bar_index, dailyopen,   xloc=xloc.bar_index, style=line.style_solid,extend=extend.right)
line.set_color(line1, color.black)
line.set_width(line1, 1)
