with interactive brokers , i wanted to watch options trading on corn and soybean futures and there was no activity or even bids or asks prices on the screen. i used smart routing to select an exchange and put up all options for current month and near month. is there a specific exchange i should choose or is options trading for these futures not possible with interactive brokers. also , is the volume for these options high enough to realistically be traded. are there other brokers where i could trade these options. thanks
