here is there web-site, which has barely nothin...
http://www.kcco.com/
Have been trying to find out what I can about them...hasn't been much. From what I have found, they're in inactive clearing firm for the CME, and they trade CME/CBOE mostly index work.
http://www.cme.com/files/GAD.pdf
There is a very good CME "Access Directory", a compiled list of brokers / platforms, trade groups, and some other info. KC's info is on page 69...reads as follows...
"KC-CO II, LLC is a Chicago-based trading firm
that has had a strong presence in the
derivatives industry since 1986. KC-CO is a
private, member-owned firm trading exclusively
for its own accounts. The firm primarily makes
markets in index and interest rate options on
the three Chicago derivatives exchanges, both
on the exchange floors and over electronic
interfaces. KC-CO is an inactive clearing
member of CME.
The firm has a strong history of promoting its
trading assistants to firm traders after their
extensive training both on the trading floor, in
trading strategy meetings and during
supplemental classroom sessions.
KC-CO utilizes proprietary trading and risk
management software developed and
maintained by in-house information technology
and quantitative research personnel."
Anyways, that's what I can help out with. Will post here if I find anything more out. Anybody else have info / know anyone from the firm? All thoughts welcome.
