Yes I have stopped using renko because I couldn't make it work for me as I wanted. I feel that renko, the way is implemented in metatrader favors more intra day traders and I can't be a intra day trader because I have many work and family commitments. So trading non time based charts for me is very difficult.
I noticed you posted a question in my abandoned renko journal. Sorry, I didn't see that either. I will respond to that later when I come back from work.
