I've been day trading at Echo for a two months and do an average of 10,000 shares a day. At the moment I pay 0.0075/share (NYSE). I'm wondering how much volume I have to do daily to negotiate what appears to be the industry standard of 0.005/share. My volume is slowly rising as I gain experience and confidence, but naturally the sooner I get a lower rate the better off I'll be. Any of you prop traders out there have any ideas. I'm basically looking for some context/basis for comparison.
