Pine Script V5：实现基于SuperTrend的蜡烛颜色永久生效

问题现象 #

基于SuperTrend指标修改K线蜡烛颜色时，仅当鼠标悬停在SuperTrend线上时，蜡烛颜色才会变化，无法始终保持对应状态。

原代码 #

//Supertrend
atrPeriod = 10
factor = 3
[supertrend, direction] = ta.supertrend(factor, atrPeriod)

//Line Plots
LineColorUp = direction < 0 ? color.green : na
SuperTrendUpPlot = plot(supertrend, color = LineColorUp, linewidth = 2, title = "SuperTrendUpPlot")

LineColorDown = direction >= 0 ? color.red : na 
SuperTrendDownPlot = plot(supertrend, color = LineColorDown, linewidth = 2, title = "SuperTrendDownPlot")

//fill
bodyMiddle = plot((open + close) / 2, display=display.none)

fillColor = direction < 0 ? color.green : color.red
fill(bodyMiddle ,SuperTrendUpPlot, color.new(fillColor, 90), fillgaps = false)

//Candle Color
candleColor = direction < 0 ? color.rgb(0, 255, 8) : color.rgb(255, 0, 0)
plotcandle(open, high, low, close, color = candleColor)

问题原因 #

TradingView默认K线会覆盖自定义plotcandle绘制的蜡烛，只有鼠标悬停在指标线上时，临时调整了显示层级，才会看到自定义颜色的蜡烛。另外原代码未设置蜡烛的边框和灯芯颜色，也会导致视觉上的显示异常。

修正后的代码 #

//Supertrend
atrPeriod = 10
factor = 3
[supertrend, direction] = ta.supertrend(factor, atrPeriod)

//Line Plots
LineColorUp = direction < 0 ? color.green : na
SuperTrendUpPlot = plot(supertrend, color = LineColorUp, linewidth = 2, title = "SuperTrendUpPlot")

LineColorDown = direction >= 0 ? color.red : na 
SuperTrendDownPlot = plot(supertrend, color = LineColorDown, linewidth = 2, title = "SuperTrendDownPlot")

//fill
bodyMiddle = plot((open + close) / 2, display=display.none)

fillColor = direction < 0 ? color.green : color.red
fill(bodyMiddle ,SuperTrendUpPlot, color.new(fillColor, 90), fillgaps = false)

//Candle Color - 修正部分
candleColor = direction < 0 ? color.rgb(0, 255, 8) : color.rgb(255, 0, 0)
// 设置边框和灯芯颜色与主体一致，强制叠加在主图最上层
plotcandle(open, high, low, close, 
           color = candleColor,
           wickcolor = candleColor,
           bordercolor = candleColor,
           overlay = true)

额外操作提示 #

在TradingView图表设置的「样式」选项中，将默认K线设置为「隐藏」，确保自定义蜡烛完全替代原生K线显示。
