I ran into a limitation of the multibroker functionality of zorro, which I am really enjoying, while developing a tool. A given strategy can apparently only access assets with at most four brokers. I find this restriction too stringent and I would appreciate it if this limit would be increased to for instance 12. In case this would consume unnessary resoures for tools/strategies that do not require so many multiple broker connections, I assume one could add an appropriate parameter in the ini file to keep everybody happen.
