交易视图中的趋势线，其中包含文本（pinescript）

Question

在 tradingview 中，我们可以绘制一条趋势线并在其上放置文本、设置模板等……是否可以使用 pine 脚本绘制一条线并将模板或文本分配给该线？ 或者我们是否需要在 label 中添加文字绝对在此处输入图像描述

对的，这是可能的。 请阅读此内容以获取更多信息。

以下是 pivot 点的示例：

//@version=4
study("Pivot Points Standard", overlay=true)
higherTF = input("D", type=input.resolution)
prevCloseHTF = security(syminfo.tickerid, higherTF, close[1], lookahead=true)
prevOpenHTF = security(syminfo.tickerid, higherTF, open[1], lookahead=true)
prevHighHTF = security(syminfo.tickerid, higherTF, high[1], lookahead=true)
prevLowHTF = security(syminfo.tickerid, higherTF, low[1], lookahead=true)

pLevel = (prevHighHTF + prevLowHTF + prevCloseHTF) / 3
r1Level = pLevel * 2 - prevLowHTF
s1Level = pLevel * 2 - prevHighHTF

var line r1Line = na
var line pLine = na
var line s1Line = na

if pLevel[1] != pLevel
    line.set_x2(r1Line, bar_index)
    line.set_x2(pLine, bar_index)
    line.set_x2(s1Line, bar_index)
    line.set_extend(r1Line, extend.none)
    line.set_extend(pLine, extend.none)
    line.set_extend(s1Line, extend.none)
    r1Line := line.new(bar_index, r1Level, bar_index, r1Level, extend=extend.right)
    pLine := line.new(bar_index, pLevel, bar_index, pLevel, width=3, extend=extend.right)
    s1Line := line.new(bar_index, s1Level, bar_index, s1Level, extend=extend.right)
    label.new(bar_index, r1Level, "R1", style=label.style_none)
    label.new(bar_index, pLevel, "P", style=label.style_none)
    label.new(bar_index, s1Level, "S1", style=label.style_none)

if not na(pLine) and line.get_x2(pLine) != bar_index
    line.set_x2(r1Line, bar_index)
    line.set_x2(pLine, bar_index)
    line.set_x2(s1Line, bar_index)
