Quote from ProfLogic:
Anytime you create a chart based on variables, the outcomes or what will be viewed on those charts will be exaggerated randomness & chaos.
Tick charts are variable based because each tick has a different embedded value of volume. Someone trading 200 contracts in a single transaction carries as much weight as a single transaction of one contract. That is what causes the exaggerated randomness & chaos (NOISE) on a chart. Minute charts are no better because every bar is a different weight of volume as well.
In order to see a clear view of price movement on any chart the chart needs to be created using Constant or capped Volume or Share bars. The reason is that each bar has the identical amount of volume attributed to it. When you eliminate the variable aspect of the chart you are watching you eliminate the NOISE viewed on that particular chart.
