Thank you for your question and welcome to the Optimus Community!
Based off of the features you requested, it seems that Sierra Chart might best suite your needs. We offer quite a few different platforms that include Renko Charts, but Sierra Chart offers a vast amount of customization options.
Sierra Chart provides traders with the ability to set their Renko Charts based off of tick value, rather than traditional time frames. Also, the platform allows users to specify the number of tickers per Renko bar, this is known as the bar size. Each 1 tick is equivalent to the tick size, therefore, if the tick size is .25 and you specify 4 ticks, then this is equivalent to 1.0 as an actual value (This will mean that each Renko bar body will have a length of 1.0).
Sierra Chart is packed full of customizable features. Although it has a bit of a learning curve, once mastered, it proves to be quite a powerful platform.
I’d suggest taking a look at this documentation directly from the Sierra Chart support team, you might find it quite helpful and it may clear up some questions you may have about the software’s Renko Bar Charts feature: https://www.sierrachart.com/index.php?page=doc/RenkoCharts.html
