我想在 Auto Fib Retention Script 的右侧屏幕末尾显示价格 label，这是一个内置的交易视图

Question

In the TradingView built-in script, Auto Fib Retention Script, I'd like to pin the label next to the price line at the right end of the screen. scripted:

x_draw_label (price, txt, txtColor) => 
    x = labelsPosition == "Left" ? line.get_x1(lineLast) : line.get_x2(lineLast) 

When you select the right side of the label position, only the maximum line.get_x2(lineLast) is moved. I would appreciate it if you could tell me how to fix it next to the price line at the end of the right screen.

Answer 1

Use:

_draw_label(price, txt, txtColor) => 
    x = labelsPosition == "Left" ? line.get_x1(lineLast) : bar_index
    var id = label.new(x=x, y=price, text=txt, textcolor=txtColor, style=label.style_none)
    label.set_xy(id, x, price)
    label.set_text(id, txt)
    label.set_textcolor(id, txtColor)
