Volume vs Price

This great visual tool shows us relative difference between price of the stock and volume of the stock during past 10 days. This allows us to see whether buying or selling "has legs". For instance, when price is still increasing while volume is decreasing it indicates that buying pressure is loosing its steam and reversal is on horizon.
