我可以使用 hline 来获取动态值吗？

Question

我正在交易视图上开发一个指标。我的愿望是对我收到的动态值进行（ohcl）计算并使用地平线。对于动态值，推荐使用new.line函数，我也使用它，但是我不能像hline那样直接将价格写入右侧的价格栏，这在绘制图表时不太好。标签选项等。这不是很令人鼓舞。有针对这个的解决方法吗？我正在分享我的示例代码脚本。

yuksek = request.security(syminfo.tickerid, currentTF, high[1], lookahead=barmerge.lookahead_on)
dusuk = request.security(syminfo.tickerid, currentTF, low[1], lookahead=barmerge.lookahead_on)
kapanis = request.security(syminfo.tickerid, currentTF, close[1], lookahead=barmerge.lookahead_on)


pp = (yuksek + dusuk + kapanis) / 3
r1 = 2 * pp - dusuk
r2 = pp + yuksek - dusuk
r3 = yuksek + 2 * (pp - dusuk)
s1 = 2 * pp - yuksek
s2 = pp - (yuksek - dusuk)
s3 = dusuk - 2 * (yuksek - pp)


var line_pp = line.new(na, na, na, na, width=1, color=color.black)
var label_pp = label.new(na, na, '', style=label.style_label_down, color=color.black, textcolor=color.white, size=size.small)

var line_r1 = line.new(na, na, na, na, width=1, color=color.green)
var label_r1 = label.new(na, na, '', style=label.style_label_down, color=color.green, textcolor=color.white, size=size.small)

var line_r2 = line.new(na, na, na, na, width=1, color=color.green)
var label_r2 = label.new(na, na, '', style=label.style_label_down, color=color.green, textcolor=color.white, size=size.small)

var line_r3 = line.new(na, na, na, na, width=1, color=color.green)
var label_r3 = label.new(na, na, '', style=label.style_label_down, color=color.green, textcolor=color.white, size=size.small)

var line_s1 = line.new(na, na, na, na, width=1, color=color.red)
var label_s1 = label.new(na, na, '', style=label.style_label_down, color=color.red, textcolor=color.white, size=size.small)

var line_s2 = line.new(na, na, na, na, width=1, color=color.red)
var label_s2 = label.new(na, na, '', style=label.style_label_down, color=color.red, textcolor=color.white, size=size.small)

var line_s3 = line.new(na, na, na, na, width=1, color=color.red)
var label_s3 = label.new(na, na, '', style=label.style_label_down, color=color.red, textcolor=color.white, size=size.small)

我尝试画线但失败了。

Answer 1

您不能在本地范围内使用

hline()

，也不能将其与动态值一起使用。

通常的解决方法是使用

line

和

label

。但是，您表示您正在寻找不同的解决方案。

一种解决方案可能是用

plot()

绘制它们并使用

show_last=1

这样你就不会有历史记录和

trackprice=true

这样它将是一条水平虚线。

然后，在图表设置中，您可以从

Name

下拉菜单中选择

value

和

Indicators and financials

。这样，它就会在价格刻度上标记出价值和名称。

currentTF = timeframe.period
yuksek = request.security(syminfo.tickerid, currentTF, high[1], lookahead=barmerge.lookahead_on)
dusuk = request.security(syminfo.tickerid, currentTF, low[1], lookahead=barmerge.lookahead_on)
kapanis = request.security(syminfo.tickerid, currentTF, close[1], lookahead=barmerge.lookahead_on)

pp = (yuksek + dusuk + kapanis) / 3
r1 = 2 * pp - dusuk
r2 = pp + yuksek - dusuk
r3 = yuksek + 2 * (pp - dusuk)
s1 = 2 * pp - yuksek
s2 = pp - (yuksek - dusuk)
s3 = dusuk - 2 * (yuksek - pp)

plot(r1, "R1", color.red, show_last=1, trackprice=true)
plot(s1, "S1", color.green, show_last=1, trackprice=true)

Kolay 明胶。

Answer 2

感谢您的评论。不幸的是我无法得到我想要的。我使用 barstate.islast 删除历史点。这次，右侧价格栏中包含的点被删除。我想我唯一的机会是使用 new.line...
