Quote from ProfLogic:
Tick Charts are not consistent. GLOBEX destroyed them and any consistency they USED to have last August when they started arbitrarily grouping transactions together.
On top of that Ticks are transactions and the though seemingly consistent they are made up of a varying amount of shares or contracts per bar. Each transaction or Tick contains different volume. I've found, over 11 years of research, that by eliminating the variables in your charting you increase the clarity of the price movement contained in each particular chart. By trying to view a chart where volume varies, bar by bar, it is like adding static to a television picture. You can see the picture but not clearly.
Constant Volume Bar charts, not just Volume Bar Charts are the most consistent charts that exist. Ensign & MultiCharts are the only charting companies that offer them. Candlesticks are better used on Constant Volume Bar Charts as well.
Regardless of how you trade or your method or system, clarity and accuracy of price movement is critical to making consistent and accurate decisions based on your own particular edge.
