An easy-peasy way to replace OHLC bars with candles on Range Bars chart. For further improvement you could also make "Up Bars" and "Down Bars" colors transparent (open Range Bars chart settings, do the change and save as default).
This indicator determines the time (in minutes) for which a bar of the Range Bar type was formed.
In order to avoid errors in the calculations, a weekend check is immediately carried out (one day if it is a holiday or two days if it is a weekend).
If there are more days off, then the information on the first bar after the weekend may be incorrect.
