When was TT's DOM first publically shown?

Quote from rtrading:

saw it first in May 2000

Thanks for the info. Do you, by chance, remember where this was?

I'm esspecially interested in sightings before February or March 2000.

I remember GL Trade had a ladder in either '98 or '99

TT plug was pulled at Refco on Monday. Now all traders using Refcopro, ECCO or RTS.
