Enzolytics Inc (ENZC)

As far as I know, Fidelity doesn't charge a fee for OTC trades. The rest of the retail brokers want fees in the neighborhood of $7. If you place an order and shares change hands, you'll pay the $7 even if your order doesn't completely fill, times out at the end of the day, or you cancel it.

There's usually some order settings where you can specify All-or-Nothing for your order. This ensures the broker won't fill for half your shares and leave the order hanging. I started doing this for smaller ENZC orders since mine kept getting fragmented into blocks as small as 100 shares.
