F&O Trading Basics — Futures and Options Explained

Futures and Options (F and O) is the most traded segment of the Indian stock market. On any given day, the F and O segment on NSE handles 20 to 50 times more volume than the cash (delivery) segment. But F and O trading is also where most retail traders lose money. This guide will help you understand the basics so you can make informed decisions.

What Are Derivatives?

Futures and Options are types of financial derivatives. A derivative is a contract whose value is derived from an underlying asset — in this case, a stock or an index. You are not buying or selling the actual stock. Instead, you are trading a contract that represents the future price movement of that stock. Think of it like a bet on where the price will be at a future date, except it is regulated by SEBI and traded on NSE.

Futures Contracts

A futures contract is an agreement to buy or sell an asset at a predetermined price on a specific future date. For example, a Nifty 50 futures contract for March 2026 expiry means you agree to buy or sell Nifty at a certain price on the last Thursday of March 2026. If Nifty is at 23,000 and you buy a futures contract, you profit if Nifty goes above 23,000 and lose if it goes below.

Futures are traded in lots. One lot of Nifty 50 futures is 25 units. So if Nifty moves 100 points in your favor, your profit is 100 multiplied by 25, which equals Rs 2,500. The lot size varies for different stocks — Reliance might have a lot size of 250, while HDFC Bank might have 550. You need margin (typically 15 to 20 percent of the contract value) to trade futures, not the full amount.

Options Contracts

Options give you the right, but not the obligation, to buy or sell at a certain price. There are two types — Call Options (CE) give you the right to buy, and Put Options (PE) give you the right to sell. This is where it gets interesting.

Let us say Nifty is at 23,000. You buy a 23,200 CE (Call Option) for Rs 100. This means you are paying Rs 100 for the right to buy Nifty at 23,200 on expiry day. If Nifty goes to 23,500 on expiry, your option is worth Rs 300 (23,500 minus 23,200). Your profit is Rs 300 minus Rs 100 (premium paid) = Rs 200 per unit. With a lot size of 25, that is Rs 5,000 profit.

But if Nifty stays below 23,200 on expiry, your option expires worthless and you lose the entire Rs 100 premium, which totals Rs 2,500 (Rs 100 times 25 lot size). This is the maximum you can lose as an option buyer — your risk is limited to the premium paid.

Expiry Dates

In India, Nifty and Bank Nifty options expire every Thursday. Stock options and futures expire on the last Thursday of every month. Check our F and O Expiry page for a live countdown to the next expiry along with the complete 2026 economic calendar.

Why Most Traders Lose in F and O

SEBI data shows that roughly 90 percent of individual F and O traders lose money. The reasons are clear — most people trade without proper understanding, they over-leverage (take positions much larger than their capital can handle), they do not use stop losses, and they treat F and O as gambling rather than calculated trading. Options especially have time decay working against buyers — even if the market moves in your direction, if it does not move fast enough, your option loses value every day.

Should You Trade F and O?

If you are a beginner, the honest answer is no — not yet. Start with cash equity investing, understand how markets work, and only after at least a year of experience should you explore F and O with small amounts. If you do decide to trade, start with buying options (limited risk) rather than selling options or trading futures (unlimited risk). And never trade with borrowed money or money you cannot afford to lose.
