Unlike other implementations I found here on TradingView, this implementation make use of a Renko-like pattern, very similar to how it is described in David H. Weis' book. The settings for the pattern are very similar to the standard Renko settings here on TradingView, in the "Renko Assignment Method" you either chose "ATR" or "Traditional" (read more about it here ). The ATR length or the brick size is then entered in the textbox "Value". You can also chose another setting in the "Renko Assignment Method" drop down named "Part of Price" which calculate the brick size from the current close and divide it by the value in the text box "Value". It is also possible to chose if the pattern shall use the high/low, the open/close or just the close as the most extreme values in its calculation, you select this in the drop down "Price Source".
TradingView's pine script does currently not support to print non-static text on the chart, so it is not possible at this point to write out the on the chart. It is also not possible to have both an overlay and separate chart pane in the same indicator, therefor this indicator is split up in two.
You can find the indicator here:
In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
