Only that almost all brokers I've talked to are incredibly ignorant of and hate and dont want to deal with penny stocks

mm's/ brokers/ hedge funds make a lot of money on such stocks and we pay the same online commissions of an expensive stock and such ecn trades reportedly only cost brokers 8c each

perhaps they are not sure whether the mm's they contract with-if there are any for NNLX-will be able to fill orders, despite the usual naked shorting by mm's

I dont know whether NNLX is serviced by one mm or none- at TDA no mm is listed- instead it says "otc other" whatever that means-never seen that before on other stocks- I bought more NNLX at 10c at TD without any problem

if a broker has no contract with a mm which services NNLX that would presumably require manual intervention by a brokers sweat shop
and reduce or even eliminate (how shocking) any broker profit on retail purchases of NNLX-
in such case a broker very likely would like to get out of dealings with such a stock


from 2011 to 2013 during a political move to eliminate low pennies brokers suddenly, without notice or due process, restricted thousands of stocks so you could not sell such stocks (the opposite of your problem)
I dont expect such unconstitutional moves at this time either way
