pine-script - 标记水平 EMA 线（变量）
问题描述
这是我使用 atm 的代码。（感谢比约恩·米斯蒂安）
len1 = input(10, minval=1, title="Length")
len2 = input(21, minval=1, title="Length")
len3 = input(55, minval=1, title="Length")
len4 = input(100, minval=1, title="Length")
len5 = input(200, minval=1, title="Length")
src = input(close, title="Source")
var bool show_hlines = input(true, "Show horizontal lines", input.bool)
var bool show_emas = not show_hlines
var color_entryema = color.green
var color_fastema = color.orange
var color_mediumema = color.red
var color_slowema = color.white
var color_veryslowema = color.purple
var line_entryema = line.new(x1=na, y1=na, x2=na, y2=na, xloc=xloc.bar_time, extend=extend.both, color=show_hlines ? color_entryema : na, style=line.style_solid)
var line_fastema = line.new(x1=na, y1=na, x2=na, y2=na, xloc=xloc.bar_time, extend=extend.both, color=show_hlines ? color_fastema : na, style=line.style_solid)
var line_mediumema = line.new(x1=na, y1=na, x2=na, y2=na, xloc=xloc.bar_time, extend=extend.both, color=show_hlines ? color_mediumema : na, style=line.style_solid)
var line_slowema = line.new(x1=na, y1=na, x2=na, y2=na, xloc=xloc.bar_time, extend=extend.both, color=show_hlines ? color_slowema : na, style=line.style_solid)
var line_veryslowema = line.new(x1=na, y1=na, x2=na, y2=na, xloc=xloc.bar_time, extend=extend.both, color=show_hlines ? color_veryslowema : na, style=line.style_solid)
f_moveLine(_id, _x, _y) =>
line.set_xy1(_id, _x, _y)
line.set_xy2(_id, _x+1, _y)
entryema = ema(src, len1)
fastema = ema(src, len2)
mediumema = ema(src, len3)
slowema = ema(src, len4)
veryslowema = ema(src, len5)
if (hour==0 and minute==0 and year(time)==year(timenow) and month(time)==month(timenow) and dayofmonth(time)==dayofmonth(timenow))
f_moveLine(line_entryema, time, entryema)
f_moveLine(line_fastema, time, fastema)
f_moveLine(line_mediumema, time, mediumema)
f_moveLine(line_slowema, time, slowema)
f_moveLine(line_veryslowema, time, veryslowema)
plot(entryema, color=show_emas ? color_entryema : na, linewidth=2, title="Entry EMA")
plot(fastema, color=show_emas ? color_fastema : na, linewidth=2, title="Fast EMA")
plot(mediumema, color=show_emas ? color_mediumema : na, linewidth=2, title="Medium EMA")
plot(slowema, color=show_emas ? color_slowema : na, linewidth=2, title="Slow EMA")
plot(veryslowema, color=show_emas ? color_veryslowema : na, linewidth=2, title="Veryslow EMA")
现在我想用 10、21 EMA 等标记这些水平 EMA 线。我已经为每天和每周关闭水平线添加了一个现成的代码，并尝试为此使用“相同”代码，但似乎没有任何效果。我遵循了相同的程序，但我可能遗漏了一些重要的东西。
lblOffset = input(30, title="Label Offset")

f_delete(tf) =>

解决方案
你的代码工作得很好。
我认为您在图表上向右滚动的距离不够远。
您将默认lblOffset设置为30，因此文本将在右侧 30 个小节处。
请参阅下面由您的代码制作的屏幕截图（未更改）。
它清楚地显示了Daily Close蓝线上的文字。
更新代码以显示标签：
