Any broker let you trade the same stock

for a flat fee (all day). There used to be deals like this.

There was a link from inverstorsguide.com saying:
________________________________
* Your Discount Broker - Day traders can pay $30 to trade in and out of any stock for a full day.

That link now goes to http://www.ydb.com/.
You may have to ask them if that type of offer still exists.

If I remember correctly, when you dug deeper, they added ECN fees and other external costs (SEC 31, NASD TAF, etc.). I think I'm remembering ProTrader (who is gone now). Would probably only work for self-clearing firms, unless they also pass along clearing costs.
