|First Trust ISE Global Platinum ETF|
|The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the ISE Global Platinum(TM) Index.
The fund will normally invest at least 90% of its net assets (plus the amount of any borrowings for investment purposes) in securities or in depositary receipts representing securities in the index. The index is designed to provide a benchmark for investors interested in tracking public companies that are active in platinum group metals ("PGM") mining based on revenue analysis of those companies. The fund is non-diversified.|
