Not sure if that's exactly what you're looking for? https://www.tradingview.com/script/cgHGBnH9-Naked-Intrabar-POC/

You can first define number of bars from last bar that you want to check for open/close. At the last bar you can run for loop for that many bars. At each iteration of loop you can keep calculating the maxiumum high and minimum lows that occured after the selected bar. If open/close is not breaching them, then draw the line. Example below

//@version=5

indicator(title="Unbreached High/Low by Rohit", shorttitle="URR",overlay=true,max_lines_count=500,max_labels_count=500,max_bars_back=1500)
var maxbars = input.int(20,title="max bars")
var maxhigh=high
var minlow=low
if barstate.islast
    var openclosearray=array.new_float()
    maxhigh:=high
    minlow:=low
    for i = 1 to maxbars
        if open[i]<close[i] and open[i]<minlow
            line.new(bar_index-i,open[i],bar_index,open[i],extend=extend.right)
        if open[i]>close[i] and open[i]>maxhigh
            line.new(bar_index-i,open[i],bar_index,open[i],extend=extend.right)
        if close[i]<open[i] and close[i]<minlow
            line.new(bar_index-i,close[i],bar_index,close[i],extend=extend.right)
        if close[i]>open[i] and close[i]>maxhigh
            line.new(bar_index-i,close[i],bar_index,close[i],extend=extend.right)
        if low[i]<minlow
            minlow:=low[i]
        if high[i]>maxhigh
            maxhigh:=high[i]
