Renko Chart MT4 makes a self-regulating Renko diagram where all bars are appeared as Renko "deters" without any wicks. The size of the "squares" is settled in the settings.
Oneself controlling Renko outline is showed up on history similarly as on the web. The diagram is stimulated no not actually at standard breaks.
Find consistently about the Renko layout plotting rules and look at the open Renko Chart MT4 source code in the article "How to build up a non-standard outline pointer for Market" (in Russian as of 28.04.2016; to be changed over into English soon).
