let's say the market gets to a level where it could reverse. the market could spend a long time or trade a lot of volume around that level.
- with range bars you only get a single bar for the top/bottom. only price will be considered
- with minute bars you might get several bars. depending how much time was spent at that level
- with volume bars you also might get more than one bar. depending of course how much volume was traded
I think it's easier to analyze as few bars as possible. and I want to see what happened at that price in a single bar if possible.
of course if you choose "big" charts, like 30 minutes or 100,000 volume, you also might get only one bar at the top/bottom. but for me there's too much information in those long bars. and also (for me), it's more about analyzing than looking for reliable signals.
