Average Daily Volume (for new listings)

[tradephoric]

Average Daily Volume (30 day) code for a custom watchlist:

Plot ADV  = Average(Volume(period = "day" )[1], 30) ;

When a stock has been trading for less than 30 days it displays NaN. Is there a way to show the average daily volume for however many days a new stock has been trading?

Example:
IPO XYZ has been trading for 2 days....
Day 1 Volume = 2 million
Day 2 Volume = 1 million

Average daily volume should display 1.5 million
