如何使用 TradingView Pine Script 覆盖文本？

  • 772

我想在我的 TradingView 图表上叠加文字。我想在 RSI 85 的水平位显示“超买”，并以白色居中，并在 RSI 15 的水平位显示“超卖”。但我不知道该怎么做。标签或文字显示 RSI 85 的水平位超买，RSI 15 的水平位超卖。谁能帮我实现一下，谢谢

我如何添加文本？

这是我目前拥有的代码：

//@version=4
study(title="Relative Strength Index", shorttitle="RSI", format=format.price, precision=2, resolution="")
len = input(14, minval=1, title="Length")
src = input(close, "Source", type = input.source)
up = rma(max(change(src), 0), len)
down = rma(-min(change(src), 0), len)
rsi = down == 0 ? 100 : up == 0 ? 0 : 100 - (100 / (1 + up / down))
plot(rsi, "RSI", color=color.rgb(255, 255, 255))
band6 = hline (85, "upper band2", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)
band5 = hline (70, "upper Band3", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)
band4 = hline (60, "upper band4", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)
band2 = hline (30, "lower band2", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)
band1 = hline (15, "lower band3", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)
band0 = hline (00, "lower band4", color=#ffffff70,linestyle=hline.style_dotted, linewidth=1)

到目前为止，我的图表是这样的：

    首先，将 v4 升级到 v5
    https://www.tradingview.com/pine-script-docs/migration-guides/overview/

    要使图表居中，您可以使用 chart.right_visible_bar_time 和 chart.left_visible_bar_time
    https://www.tradingview.com/pine-script-reference/v6/#var_chart.right_visible_bar_time

    类似这样的：

    //@version=6
indicator(title = 'Relative Strength Index', shorttitle = 'RSI', format = format.price, precision = 2)
len = input.int(14, minval = 1, title = 'Length')
src = input(close, 'Source')
up = ta.rma(math.max(ta.change(src), 0), len)
down = ta.rma(-math.min(ta.change(src), 0), len)
rsi = down == 0 ? 100 : up == 0 ? 0 : 100 - 100 / (1 + up / down)
plot(rsi, 'RSI', color = color.rgb(255, 255, 255))
band6 = hline(85, 'upper band2', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)
band5 = hline(70, 'upper Band3', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)
band4 = hline(60, 'upper band4', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)
band2 = hline(30, 'lower band2', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)
band1 = hline(15, 'lower band3', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)
band0 = hline(00, 'lower band4', color = #ffffff70, linestyle = hline.style_dotted, linewidth = 1)


f_print(_text, _level) =>
    // Create label on the first bar.
    var _label = label.new(na, na, _text, xloc.bar_time, yloc.price, color(na), label.style_none, color.gray, size.large, text.align_center)
    _centerChart = chart.right_visible_bar_time - ((chart.right_visible_bar_time - chart.left_visible_bar_time) / 2)
    // On next bars, update the label's x and y position, and the text it displays.
    label.set_xy(_label, _centerChart, _level)
    label.set_text(_label, _text)

f_print('HIGH RSI', 85)
f_print('LOW RSI', 0)
