Hey guys. I know this is an opinion only question but I'm using an online broker and feel that they are just way to high on the commission. Could one of you give a good on-line broker that doesn't cost so much if sell or buying penny stock. I find that this is what I like to do since I joined the group but can't continue giving so much to the commissions.
