what is the difference between trading in Options and Futures?


An option is the right but not the obligation to do something. If you buy a call you have the right to buy the futures contract later at a fixed price if it makes sense to do so. Otherwise you can legally walk away and be out only what you paid for the option in the first place. If you bought the future directly, and it went up, great. But if it went down, you would be responsible for the loss.
