Not sure what platform or database you're using but my three sources (ToS, OCC, and CBOE) show the following at the COB today (16:00 EDT/20:00 UTC). Of course the numbers vary by a few contracts between data sources but all pretty much paint an accurate picture.
Daily Options Volume COB 3/12/2015
EEM iShares MSCI Emerging Markets Indx (ETF) 18,400 PUTS 83,000 CALLS
GDX Market Vectors Gold Miners ETF 62,900 PUTS 19,400 CALLS
GLD SPDR GOLD SHARES 33,400 PUTS 31,000 CALLS
All the numbers have been rounded to the nearest 50 contracts. GLD, GDX, and EEM all had more than 50,000 contracts traded today. EEM was over a 100 thousand, GDX over 80 thousand, and GLD about 65,000 thousand.
As an aside, FXE had a trading volume of 21,000 and UUP 16,000. Neither of those meet my criteria. I like lots of volume, open interest, lots of expiration months, and narrow bid/asks. Currency ETFs don't provide most of that.
Again, you may want to check your reference and data sources.
