How to use
Basic technical analysis has shown that a support level is a price level which will support a price on its way down and a resistance level is a price level which will resist price on its way up. Therefore, one can conclude that a price level near the bottom of the profile which heavily favors the buy side in terms of volume is a good indication of a support level. The opposite is also true. A price level near the top of the profile which heavily favors sell side volume is a good indication of a resistance level.
