pine-script - 如何在右侧放置指定的斐波那契标签，并缩短线条以不一直延伸到右侧？

Question

我有一个代码可以根据买入/卖出信号自动生成指定的斐波那契水平。我试图将标签放在右侧而不是左侧，并缩短线条，使它们不会一直向右延伸，但只能延伸这么多，最好让线条的开头与购买对齐/sell 印有蜡烛的蜡烛。我一生都无法弄清楚如何做到这一点。

Answer 1

对于您的标签x值和行x2值，您可以使用bar_index + 整数，例如

label.new(x = bar_index + 50, y = ......)

并将extend行的参数更改为extend.none

标签样式还控制标签的原点，因此您可能想尝试使用label.style_label_lower_right
