Difference between futures and options
In futures both sides must trade. In options the buyer pays for a right and only the seller is obliged.
Futures and options are both derivatives: contracts whose value comes from an underlying such as the Nifty 50 index or a stock. The difference is who is bound. In a futures contract, buyer and seller are both obliged to settle at the agreed price on expiry. In an options contract, the buyer has a right and only the seller has an obligation.
That one difference drives everything else: what you pay to enter, how your profit and loss behave, and who pays margin each day. Series VIII tests it directly, in Unit 4 of NISM's curriculum.

Same view, two instruments: a worked example
Illustrative numbers, not market prices. Nifty is at 25,000 and you are bullish. Choice A: buy Nifty futures at 25,000. Choice B: buy the 25,000 call for a premium of 200. Figures are per unit of the index at expiry; multiply by the lot size the exchange sets for rupees.

What the example shows
- check_circleThe futures line is symmetric: 500 points up earns what 500 points down loses.
- check_circleThe call's loss stops at the 200 premium however far Nifty falls. On the upside it trails the futures by exactly that premium.
- check_circleThe call breaks even at strike plus premium, 25,200. The futures break even at the entry price, 25,000.
- check_circleThe option buyer pays for the protection up front. Since February 1, 2025, SEBI requires brokers to collect the net option premium from buyers upfront.

The option seller is not the option buyer
Limited loss belongs to the option BUYER only. The seller of that same call earns at most the 200 premium and faces losses that grow with every point Nifty rises above 25,200, which is why the seller, like both sides of a futures trade, posts margin and is marked to market daily.
How Series VIII tests this
Most questions are statement checks drawn from the workbook's comparison table: 'Both buyer and seller of an option pay margin', 'Only the futures buyer is marked to market', 'The option seller's loss is limited to the premium'. All three are false. Read each statement for which party it names.
A second pattern asks which instrument has a symmetric payoff (futures) or which gives the right but not the obligation (options, for the buyer). Numerical versions give an entry price, a premium and an expiry level and ask you to compare the two payoffs, as in the table above.
FAQs
What is the main difference between futures and options?expand_more
A futures contract obliges both buyer and seller to settle at the agreed price. An option gives the buyer a right without an obligation, while the seller must honour it if exercised.
Which is riskier, futures or options?expand_more
It depends on which side you take. An option buyer's loss is capped at the premium. A futures position on either side, and an option seller, can lose far more than the initial outlay. This is a description of payoffs, not advice on which to trade.
Do option buyers pay margin?expand_more
No. The option buyer pays the premium, which brokers must collect upfront. The option seller and both sides of a futures contract deposit margin with the exchange through their broker.
Are options in India American or European?expand_more
European. The NISM workbook states that all index and stock options in India are European style, so the buyer can exercise only on expiry.
