US30 code

[BorderCollieLover]

In config.py there is this line: "US30": {"code": "UB", "cycle": "HMUZ", "exchange": "CME"},

Should it be UD instead of UB if it's for US ultra bond?

Thanks for sharing this repository. I definitely benefitted from your work

I think you're right. UB is Euro/Krone on Barchart. I think confusion arose because Interactive Brokers use UB. Submit a PR if you like, or I'll fix in next release
