Very simple yet effective indicator that shows bar creation speed. I think you can spot some edges using it, especially with renko or NinzaRenko bars. It can be used with any other bars as well. There are a few modes and features that it can be used with like looking for speed of close on consecutive bar patterns as well as applying a volume multiple to speed as well. All of this makes it useful in analyzing potential market turn arounds or continuation patterns. The indicator comes with source code and a code review video.
