Pine Script去除支撑位重叠区间：保留最新区间需求

我编写了一段Pine Script代码用于标记枢轴区间（pivot Zones），目前已实现区间绘制和被突破区间的移除功能，但不知道如何去除重叠的支撑区间并保留最新的那个区间。

现有代码 #

//@version=6
indicator('Support Resistance', 'SR', true, max_lines_count = 500)


//      Supoort      {

//      SR Basic Inputs                     {

doji = (high - low) * 0.1 > math.abs(open - close)
bullCandle                   = (close > open and not doji)
bearCandle                   = (open > close and not doji)

srPivotBars = input.int(4, 'Support Resistance Pivot Bars', inline = 'pivotsr', group = 'pivotsr')

// Finding pivot bars Low
srPivotLowValue = ta.pivotlow(srPivotBars, srPivotBars)

// Validating Pivot
srPivotLowTrue = na(srPivotLowValue) ? false : true

// Finding Pivots 2 candle middle point when engulfing is found
pivotLowMidPoint1 = srPivotLowValue + (math.max(high[srPivotBars], high[srPivotBars + 1]) - srPivotLowValue) / 2
pivotLowMidPoint2 = srPivotLowValue + (math.max(high[srPivotBars], high[srPivotBars - 1]) - srPivotLowValue) / 2


// Region Colors
supportLineColor = color.new(#4caf50, 50) // #00ff0080
supportFillColor = color.new(#4caf50, 70) // #00ff0033

// storing the lines in the array
var array<line> supportBottom = array.new<line>()
var array<line> supportTop = array.new<line>()



BROKENSUPPORTS() =>
    if supportBottom.size() > 0 and supportTop.size() > 0
        for [idx, m] in supportBottom
            if low < m.get_y1()
                m.delete()
                line.delete(supportTop.get(idx))
                supportBottom.remove(idx)
                supportTop.remove(idx)



//}

//      Pivot Point SR     {

showPPSR                = input.bool(true, "Pivot Levels SR", group = "ppsr")

pivotPointLow1 = srPivotLowTrue and bearCandle[srPivotBars + 1] and bullCandle[srPivotBars]
pivotPointLow2 = srPivotLowTrue and bearCandle[srPivotBars] and bullCandle[srPivotBars - 1]

if pivotPointLow1 and showPPSR and barstate.isconfirmed
    supportBottom.unshift(line.new(bar_index - srPivotBars - 1, srPivotLowValue, last_bar_index + 1, srPivotLowValue, xloc.bar_index, extend.right, color = supportLineColor))
    supportTop.unshift(line.new(bar_index - srPivotBars - 1, pivotLowMidPoint1, last_bar_index + 1, pivotLowMidPoint1, xloc.bar_index, extend.right, color = supportLineColor))

if pivotPointLow2 and showPPSR and barstate.isconfirmed
    supportBottom.unshift(line.new(bar_index - srPivotBars, srPivotLowValue, last_bar_index + 1, srPivotLowValue, xloc.bar_index, extend.right, color = supportLineColor))
    supportTop.unshift(line.new(bar_index - srPivotBars, pivotLowMidPoint2, last_bar_index + 1, pivotLowMidPoint2, xloc.bar_index, extend.right, color = supportLineColor))

BROKENSUPPORTS()



//}


//      Fill color between the lines        {

if supportBottom.size() > 0 and supportTop.size() > 0
    for i = 0 to supportBottom.size() - 1 by 1
        linefill.new(supportBottom.get(i), supportTop.get(i), supportFillColor)



//}
//}

尝试的无效重叠判断代码 #

我参照BROKENSUPPORTS()逻辑编写了如下重叠判断代码，但未生效：

overlapping() =>
    overlap = false
    if supportBottom.size() > 0 and supportTop.size() > 0
        for [idx, m] in supportTop
            if low < m.get_y1() and m.get_y1() > low
                overlap := true
                overlap
    overlap
