Its just long and short. Well you can do current month and next month, calender spreads.
Its actually not that simple to compare an OPTIONS strategy and try to mirror it with FUTURES - here's why.
Take a LIVE EXAMPLE (12:50 PM ,1st FEB)
Buy
slightly ATM/OFM CALL - 5500 CALL
slightly ATM/OFM PUT 5400 PUT
5500 CALL @ 94.55
5400 PUT @ 93.65
-----------
What is going to happen as the day progresses or even the week, the winning leg of this straddle will start adding value faster than the losing leg. It can be the PUT or the CALL. Why ? Simple - as either of the OPTION gets closer to and In the money, DELTA starts to approach 1 faster with time decay. Simultaneously, the losing LEG's delta reduces as it moves away from the strike price.
This means - your winning LEG generates more profits to cover for the losing leg by a good margin. It's not uncommon for the spread to get wider and wider as much as 30%-40%.
And similarly all other OPTION strategies with various LEGs attempt to generate a winning LEG to cover for the losing leg and more.
(I will update the data for the above example at EOD and also end of week to show that point).
Now - FUTURES - The spread hardly moves because the only variable is the premium and it does not swing as much. So for you to take such a call, you are going to invest at-least 60k in the strategy with a very low (if any) pay-off.
Another way would be to go for a HYBRID - short future, buy a call or buy a put and long future.
Basically its a game of DELTAs...

PS: Not to mention the margin investment - the above mentioned straddle is approximately costing 9k (1 call, 1 put) . If you try to do a calender spread with futures - you are investing 60k (span margin + MTM).
