Now let's look at the Volume Analysis Panel.

Buy itself the Volume Analysis Panel tells us very little. Joined with the information in the Price and Strength Analysis Panel it is a major contributor. Volume is a measure of pressure or power. It tells us whether there are more buyers than sellers and gives us an idea of how many. We calculate a green line in this panel which represents our Significant Volume Average. Using this we can see whether or not serious activity is taking place. The black moving average line gives you an idea of what normal volume looks like. In cases where buy and sell volume are significant, we put a red (high sales day) or blue (high buying day) dot under that day on our top panel, the Price Analysis Panel. This allows our users to focus on a single panel without looking around for the volume of the day.
Yellow bars indicate that the volume was nearly the same as the prior day.
