What's the difference between 'futures' and 'options'?
User MarkRisko answered to question to 15 Dec. 2014
The difference is mainly what condition they each put on the buyer/seller.
For an option, you have the right to buy or sell at the level, however it does not mean you have to.
For a future, you are obliged to buy or sell at the level agreed, which means that you can not dismiss the contract.
