I am thinking of opening a Fidelity account: And I am reading the restrictions for Commission Free etfs... It's kind of hard to understand... Anybody please help me understand their restrictions? Thanks a lot! http://personal.fidelity.com/products/trading/What_You_Can_Trade/offer-faq-popup.shtml Are there any restrictions on the commission-free ETF trades? The commission-free trades on the 30 iShares ETFs must be done online at Fidelity.com, Active Trader Pro, Wealth-Lab Pro, or through Fidelity's wireless channels. Commission-free trades apply to all buy and sell transactions on eligible iShares ETFs. All iShares ETFs are not margin eligible for 30-days from settlement, similar to mutual funds. For margin customers, positions will automatically become margin eligible in their account after 30 days from settlement.
