From my Alphatrade streamer. It's not really a standard, just what is on my streamer. Average volume is a lot like moving averages in the sense of time frame. 10 day is short term. Some look at that or 20 day or even 100-200 day. Knobias has a page that lists a lot of technical statistics. Check it out, you might find it useful.
