US20

[Plex134]

Good evening,

I was wondering if the code for US20 should read
"US20": {"code": "ZB", "cycle": "HMUZ", "exchange": "CBOT"},

Rather than
"US20": {"code": "ZZ", "cycle": "HMUZ", "exchange": "CBOT"},

ZB is the barchart symbol that corresponds to the symbol in Sysbrokers/IB/config/ib_config_futures.csv, and the CBOT symbol ZB is the 15-25 years remaining in the term to maturity.
It seems that on ZZ is now stale as well...

[bug-or-feature]

The codes in bcutils/config.py are Barchart codes, the ones in sysbrokers/IB/config/ib_config_futures.csv are IBKR codes. At the time of writing, in the Barchart world ZZ was the 20 year, and ZB the 30. Seems to be still the case:

• 20 Year T-Bond: https://www.barchart.com/futures/quotes/ZZH25/overview
• 30 Year T-Bond: https://www.barchart.com/futures/quotes/ZBH25/overview

or am I missing something?
