In order to make this solution useful for the broadest possible audience I have included user inputs to select the multiplier and length for average volume as well as the time frame.
You requested a specific value for the volume limit, however using a fixed value would make this solution extremely narrow in it's scope. The solution I have provided will automatically adjust based on the average volume and multiplier entered by each user.
input multiplier = 1.0;
input length = 14;
input timeFrame = AggregationPeriod.DAY;
def dailyVolume = volume(period = timeFrame);
def averageVolume = Average(dailyVolume, length);
def lastBar = !IsNaN(close) and IsNaN(close[-1]);
plot volumeLabel = if lastBar and dailyVolume < averageVolume * multiplier then dailyVolume else Double.NaN;
volumeLabel.SetPaintingStrategy(PaintingStrategy.VALUES_ABOVE);
