What I like about time bars is that its easy to see when the market is likely to make big moves by looking at volume. The higher volume bars always correlate with larger moves in the market. And conversely, the market tends to grind sideways in a small range when volume is very low. What I don't like about time bars is that you have to ignore a lot of data (overnight action). You also have to mess around with the time frame so that you're only looking at regular trading hours (which varies contract to contract). So using CVB does help in seeing the whole picture. But for guys that use CVB, how do you measure the the pace of market action? Without knowing the pace of market action its hard to sit out the really slow periods if you use CVB.
