Ok, I am currently an Power eTrade user right now and like the platform but I am done with these $9.99 commissions. I am looking at Lightspeed trading and didn't know if anyone has some advice on them. I am also looking into Tradestation and IB but havn't decided. Are there any hidden fees that I need to be aware with from these brokers?? I am mostly interesting in platform and trading costs. Thanks.
