Commission-free ETF restrictions
The commission-free trades on the 65 iShares ETFs must be done online at Fidelity.com, Active Trader Pro®, Wealth-Lab Pro®, or through Fidelity's wireless channels.
Note: A short-term trading fee of $7.95 will be charged for any sales that occur within 30 days of the original purchase of the ETF. This fee is being waived for all customers through July 31, 2013.
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.
Options on any iShares ETF products are not commission-free.
