I have built my own improved range-bar type, as well as working with Renko, P&F and others (volume, tick, and combinations) over the years. Finally I use a few different types, but the patterns which present to me are in all, some charts just allow you to find them more quickly and easily. I currently use a type of range bar, and a basic time series for decision making. What's interesting is seeing how indicators can become much more accurate when used on a non-standard timeseries chart such as a Renko. Most importantly, the type of bar is to be used as a simplification for human or machine decision making. It's always an abstraction over data.
