如何在延伸的线上获得价值-TradingView Pine脚本 [英] How to get value at a point of line extended - TradingView Pine script

问题描述

我使用下面的代码画一条线:

Im using the code below to draw a line:

//@version=4

simplesma = sma(close, 14)

var line3 = line.new(bar_index[0], high[0], bar_index, low, extend = extend.right)
line.set_xy1(line3, bar_index[5], simplesma[5])
line.set_xy2(line3, bar_index[3], simplesma[3])

该线已使用历史记录中的2点绘制.

That line has been drawn using 2 points in the history.

然后我使用此代码绘制图

And then I use this code to draw a plot

price_point = line.get_price(line3,bar_index)
plot(price_point, title='Price', color=#ffcc00, transp=30)

我正在尝试在标签上显示值，但是以下代码不起作用:

Im trying to display the value on a label but the following code does not work:

var label3 = label.new(bar_index, high, text = "Value: "+ tostring(price_point, "#.########"), style = label.style_label_lower_left, color=#ffcc00, textcolor=#ff0000)
label.set_xy(label3,bar_index, price_point)

您能帮我在标签上显示吗?

Can you please help me to show it on label ?

推荐答案

变量 price_point 是当前柱线(bar_index)上的值.您不需要使用函数 tostring().

The variable price_point is the value at the current bar (bar_index). You don't need to use the function tostring().
