I've been with a firm for 6 months as a retail trader and proved I'm a good trader. For the first 2 months I was trading relatively light, about 50K shares/day and was paying $6/1000 shares. I've been trading around 150K shares/day for the last 4 months and will trade this volume or higher from now on. It's time for me to renegotiate my commission rate. As I said, I currently pay $6/1000 shares + SEC fees. I trade NASDAQ stocks only. What should I expect to pay given I trade about 150K shares/day? What do people out there pay? Also, does anyone with experience negotiating commission rates with firms have any advice?
