Quote from Trader13:
You can usually find volume figures for options contracts on the web sites of each futures exchange (CME, CBOT, EUREX, ... ). I'm not aware of a more convenient source that combines the options contracts across exchanges and ranks them by volume.
However, volume on the option contracts rank somewhat relative to the volume on the underlying futures contract (not ALWAYS true, but close). So you might start with a volume ranking of the futures contracts which is easier to find. Monthly magazines like TASC and Active Trader both publish a table of futures contracts ranked by volume.
The FIA reports annual volume figures for the Top 20 derivative contracts, some of which are options contracts. Here is a link to one of their reports (as of the date of this post):

Hope this helps.
Quote from CPTrader:
Options on the min contracts are relatively illiguid. The ES may be Ok, but the YM is virtually dead.
Quote from Trader13:
Don't give up on an options contract because the options volume is low. If the underlying futures contract has high volume, then you might get a liquid options market with fair bid/ask spreads in any case. Worth looking at the bid/ask spread along with the volume figures, as I'm assuming the motive behind your question is to get decent execution without taking a big hit on the bid/ask spread.
I haven't looked at YM options in a while, but they are traded on an electronic exchange (not pit-traded) and may be priced favorably.
Quote from CPTrader:
Does anybody have a list/ranking of the most liquid futures options or at least a best-guess estimate of the most liquid futures options among the following market complexes - stock indices, currencies, metals, energy complex, rates, etc.
Thx!
