Hi,
I do not have an ETA on this item currently, only that it is logged in the system for review. I understand this item is important to you, however we only have a finite amount of development resources available to us, and requests for new features and changes need to be reviewed and worked on based on many factors.
I will update this thread once i have been given an alpha build to test which includes Renko OHLC.
With regards to your second query, this is not a Feature request, you will need to contact the support team (submit a ticket or send an email to [email protected]).
