The cost is $4.80 round trip.
You may want to either look around for other brokers or open up a seperate account in case IB goes down. If you are trading and IB goes down, you will not be able to get a hold of anyone fast enough for futures trading. The only way around this is to open up a seperate account elsewhere and, in those rare emergency cases, open a position opposite of your IB position and "lock the market." This won't always work if the market moves hard against you, but it is the only method I know to freeze serious losses from occuring.
Oh, and you are looking at a minimum of $2,500 to trade one contract and another few thousand for cushion. I am in your shoes since I will be trading ES very shortly and starting a journal.
