Odd lots do not have to be represented in the NBBO. They do have to
trade if given the opportunity though.
FYI, I know IB forbids you from making markets in options. I
wouldn't be surprised to see something similiar in stocks. I know
back in the old days it was not legal for complete automation, even
on a fully certed OTC dealer desk.
Good luck.

Subject: twsapi: Market Making App
Hello. I'm a seasoned vb programmer and I've been trading with
IB
for a long while. I'm thinking about writing a fully automated
Market Making application that posts bids/asks automatically. I
have
to admit, although I would have no problem writing the software
(which I don't mind sharing with everyone), I don't think I know
enough about market making. In general, when I try to post a
test 10-
share sell/buy on a NASDAQ stock inside the bid/ask spread, it
doesn't seem to show up on the Bid/Ask. Is this because I'm not
posting lots? or is there some other restriction. I would love
to
hear from people with similar interest, and get a move on this
project if it is feasible.
Cheers,
JS
