I dont have direct access, but when I went to speedtrade.com I noticed that DA traders have to pay a routing fee, that happens to be more or less depending on the ECN. If you pay .003 for a routing fee, and .003 commission, on 1k shares, thats 6.00 right there, 12 round trip. I pay 14.00 round trip at Scottrade. 7.00 for unlimited size. I dont know about other brokers, but it seems even to me. Another plus is with online brokers you dont have to worry about routing, and Scottrade has great fills IMO. The question is: 1. Would you consider day-trading from an online broker?
