Pine Script 绘图形状偏移问题

该脚本将表示高点，左侧条形较低，右侧条形较低。 我还希望这个脚本给我 HighofHighs，左高和右高较低。 我可以正常工作，但无法让标签显示在正确的栏上。

如果我使用 offset=-1，它将把它放在最近的高点上，如果我使用 offset=-high_bars_back 它根本不会偏移它。

（代码的默认设置是在最新高点上显示“HighofHighs”（使用 offset=-1），但我需要它在第二个当前高点上显示）

//@version=3

strategy(title = "Trend_v1", shorttitle = "Thrend_v1", overlay = true, 
  pyramiding = 0, default_qty_type = strategy.percent_of_equity, default_qty_value = 100, 
  calc_on_every_tick=true, initial_capital=100000)//, calc_on_order_fills=true)


//Window of time
start     = timestamp(1000, 01, 01, 00, 00)  // backtest start window
finish    = timestamp(3000, 10, 01, 00, 00)        // backtest finish window
window()  => time >= start and time <= finish ? true : false // create function "within window of time"    

//Input
showLocalTrendHighLables = input(title="Show Local Trend High Labels", type=bool, defval=true)
showRealTrendHighLables = input(title="Show Real Trend High Labels", type=bool, defval=true)

//Initialize Variables
first_high = na
second_high = na
third_high = na
local_trend_highs = na
real_trend_highs = na

//Local Trend Highs
if(nz(high[2]) < nz(high[1]) and nz(high[1]) > high)
    local_trend_highs := nz(high[1])
    third_high := second_high[1]
    second_high := first_high[1]
    first_high := nz(high[1])
else
    local_trend_highs := nz(local_trend_highs[1])
    third_high := third_high[1]
    second_high := second_high[1]
    first_high := first_high[1]

//Real Trend Highs
if (third_high < second_high and second_high > first_high)
    real_trend_highs := nz(local_trend_highs)
else
    real_trend_highs := nz(real_trend_highs[1])


//Calculate how many high bars back to display HighofHighs
high_bars_back = 0
for i = 0 to 999
    high_bars_back = i
    if(high[i] == second_high)
        break
    else
        continue


//Plots
plotshape((not (local_trend_highs == local_trend_highs[1])) and showLocalTrendHighLables, style=shape.arrowdown, location=location.abovebar, color=green, text='high', offset=-1)

//For some reason, offset=-high_bars_back doesn't shift at all
plotshape((not (real_trend_highs == real_trend_highs[1])) and showRealTrendHighLables, style=shape.arrowdown, location=location.top, color=green, text='HIGHofHIGHs', offset=-1)//offset=-high_bars_back)

plot(high_bars_back, color=blue, style=columns)

不幸的是，这不能通过“plotshape”+“offset”来实现。其原因是偏移会在给定数量的条形处移动整个系列的形状。但在您的任务中，每个 HIGHofHIGH 都需要不同的偏移值。

好消息是这个功能或多或少很快就会推出。它包含在 Pine Script 第 4 版公共草案中。该功能称为“标签”。阅读更多https://docs.google.com/document/d/12ogvjzasBJSXerSOql4b9KwkE3wUlsc5HgA5qGhoYXk/edit#heading=h.uz6ftgjlvspe
