I order 10,000 shares
price limit at .0010 but do use an all or none, AON order.
You enter a sell at market or sell at no lower than .0010 for 10,000 or less shares, down to one share, the order fills.
If my buy is all or none, and your sell is less than 10,000 shares it should not fill. Question is, which broker and what types of orders each broker allows on grey sheets. If one broker allows AON orders on greys and another does not, it could be complicated.
With the major brokers having zero commissions fees now, a new day could dawn for grey sheet trades and paint job
I suspect some brokers grey sheet trades may be done in house, since there are no MMs on the toxic grey sheet stocks.
Just a note, I did some DD a few years back and found some overseas stocks that trade on Greys with huge market caps and huge stock prices with MM bids and asks. I think one was Nestles (Swiss chocolate?) They may or may not have been ADRs.
