Is there any particular insight that time charts have to offer that isn't included in tick, range, and volume charts? I use tick, volume, and range charts in tandem, comparing the same market from the slightly different perspective of each chart. My quandary is whether or not to integrate time charts into the mix. They seem to me not only irrelevant, when compared with the other types of charts, but potentially misleading as well (e.g., when trading is slow and the market is marking time, momentum indicators respond on time charts, but on tick chart and range charts, they just hold steady). What do you all think? Is there any good reason to use time charts if one has access to the other types of charts? Thanks.
