Note: On SharpCharts, if the "Colored Bars" checkbox is checked, the Price By Volume bars will be split into two colors. The first color shows the total volume on days when the price moved higher. The second color shows the total volume for the days when prices moved lower.
i use it has an indicator to show me if there has been more buying or selling at a certain price point. as you can see, the bars cover 1 point on the idcc chart. looks to be about even in the buying and selling in the 21-22 area at this time.
