NYSE Net Advancing Volume

By Liz DeMera

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 conditon 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.
