I am actually going to go out on a limb here and say that 1m @ 6.9c is only $69,000. Often if you need liquidity in low liquidity stocks you have to put your bid out there for it to be matched. Sometimes you may pick up an investor who will bother to purchase simply because the liquidity is enough for them to make it worthwhile. Even with my relatively small portfolio I had to type in some big numbers on this and it is not often I encounter liquidity constraints. I just put in a buy order and went away on holidays and when I came back about half was filled. I can't help but feel some of
Heisenberg's uncertainty principle, or more accurately, observer effect in these situations.
In summary I am going to say fair enough question, just that I can see both sides and what may seem like a large order to some will be small change to others.
PS. For most brokers lots of $20,000 are pretty efficient. Trading in lots that are too small will eat up returns in broker fees.
