Thanks for reporting your observations. I have never tested the Multi-Symbol version of the Renko creator EA with more thatn 8 pairs. But your results show that it works fine with even more pairs (13 pairs in your experience).
Please note that in the last version of the Renko creators EAs (both Single and Multi version), there is no need to uncheck "Offline chart" option of the created Renko charts.
The Idea of using Quantum indicator seems a promising approach for the averaging technique in Renko trading. I may implement an EA to backtest this idea.
Best,
