I don't know who you guys are with, but we just checked into this the other day with Echo.
As a licensed "Pro", you can't send any order anywhere for less than 100 shares, but as long as its over 100, any number of shares is fine.
We've been filled on all kinds of odd lots over 100 over the last couple of weeks with no problems.
On another note, obviously if you have a standing order and only get filled on something like 17 shares, it's ok to take liquidity with that amount to get out.
Thanks for the info, jnbadger.
