Showing Volume on the Daily chart in Premarket

I am trying to show cumulative premarket volume on the daily chart. I cannot get pine script to show anything on the daily chart during premarket. I am trying to debug my problem (and hence put in 100K as a default for now. I thought this should create a volume candle of 100K volume on the daily chart in the premarket. But nothing shows up.

plotVolume = timeInRange(timeframe.period, "0400-0930") ? 100000 : volume
plot(plotVolume, color = color.new(palette,15), style=plot.style_columns, title="Volume")

My thought process: Get the 100K volume candle to show up on the daily chart in the premarket...once that is successful, replace 100K with a cumulative volume function of the 5M chart using request.security. Appreciate any help!

This will do it.
You must also enable extended hours on your chart.

//@version=5
indicator('Cumulative volume', 'CV')

var float   cv = 0

// Reset volume when a new day has started, or when market session begins
if (dayofmonth != dayofmonth[1]) or (session.ismarket and session.ispremarket[1])
    cv := 0

cv += volume

plot(cv, style=plot.style_columns)

For the previous solution, you must be on a lower timeframe than daily.
But I see now you want to keep your chart on the daily timeframe, AND see the pre-market volume.
To make that happen, you'll have to look inside the bar, to the lower timeframe (1 minute in my example below).
But I doubt it will work, because you need a bar on the daily timeframe to look inside of, and in the pre-market you don't have a bar yet. You can try though.
If it doesn't work, then I don't think it can be done in Pine afaik, unless someone else knows of a way to do this.

Should it work, also be aware that the data will not be the most accurate, because:
security() on lower intervals doesn’t always return reliable data. Intrabar volume information on stocks, for example, will not match >1D volume, as data for both is reported differently by exchanges.

For more information about intrabar inspection, you can take a look at Is it possible to use security() on lower intervals than the chart’s current interval?

//@version=5
indicator('IntraBar Volume')

f_intrabar(_src, _res) =>
    var int _barNo = 0
    var float _value = na
    
    if ta.change(time(_res))
        _value := 0

    _value += _src
    
intraBarVolume = request.security(syminfo.tickerid, '1', f_intrabar(volume, 'D'))
    
plot(intraBarVolume, style=plot.style_columns)
