This NYSE Net Advancing Volume chart is plotted as a 30 Day Moving Average. It is very useful in determining possible bottoming conditions in the market. Usually we get a rally from this level, however, this chart is not indicative of a good market bottom or deeply oversold condition in the market. I’ve noticed through history that once it gets down to a lower negative number that it will linger as the market is putting in a good bottom.
