The Leveraged Bet That Wipes Out 9 in 10 Retail Traders
Futures and Options (F&O) is the most popular and most dangerous segment of Indian markets. ₹100+ lakh crore in monthly turnover; ~91% of individual traders lose money per SEBI's 2024 study; cumulative retail F&O losses of ₹1.81 lakh crore over three years.
Despite the data, retail participation keeps growing — driven by zero-brokerage discount brokers, social media gurus, and the dream of quick wealth. Most traders don't understand what they're buying.
This guide explains futures contracts the way a beginner needs — what they are, lot sizes, margin requirements, mark-to-market, expiry, settlement (cash vs physical), contango/backwardation, and the SEBI-data-backed answer to whether retail should trade them.
What Is a Futures Contract?
A futures contract is a standardised agreement to buy or sell an asset at a pre-agreed price on a specific future date (expiry). Key features:
Standardised: Quantity (lot size), expiry date, and contract specs are pre-defined by the exchange (NSE)
Exchange-traded: No counterparty risk — NSE Clearing Ltd (NCL) guarantees both sides of the trade
Leveraged: You only put up margin (10-25% of contract value), not the full amount
Daily settled: Mark-to-market (MTM) every evening — profits/losses credited/debited daily
Expiry: Settled on the last Thursday of the contract month (cash for indices, physical delivery for stocks)
Indian F&O Market Structure
What's Available
Index Futures: Nifty 50, Bank Nifty, FinNifty, Nifty Midcap Select, Nifty Next 50, Sensex (BSE)
Stock Futures: ~180 individual stocks on NSE's F&O list (revised semi-annually by SEBI)
Three contract series simultaneously: Current month, next month, far month (current month is most liquid)
Lot Sizes (Illustrative)
Underlying
Lot Size
Approx Contract Value (at recent price)
Nifty 50
25
~₹6.25 lakh (Nifty ~25,000)
Bank Nifty
15
~₹8.4 lakh (Bank Nifty ~56,000)

Lot sizes are revised by NSE periodically when contract value drifts too far from ~₹15-20 lakh target. Always check NSE's current lot size before trading.
Expiry Schedule
Stock futures: Last Thursday of every month
Bank Nifty: Last Wednesday of every month (weekly expiry discontinued by SEBI in 2024)
Nifty 50: Last Thursday of every month (weekly Nifty expiry continues every Thursday)
FinNifty / Nifty Midcap Select: Last Tuesday/Wednesday of every month
How Margin Works in Futures
Two components:
SPAN margin: SEBI-defined, covers expected 1-day price movement. Calculated by NCL based on the underlying's volatility. Higher for volatile stocks/indices.
Exposure margin: Additional cushion (3-5% of contract value typically). On top of SPAN.
Total margin = SPAN + Exposure, typically 10-25% of contract value.
At 6x effective leverage, a 1.5% adverse move in Nifty (~375 points from 25,000) = 9% loss on your margin. A 5% adverse move = 30% loss. A 10% adverse move = 60% loss. The math means even a "normal volatility day" can wipe out 30-50% of your margin if you're on the wrong side.
Mark-to-Market (MTM) — Daily Settlement
Unlike cash equity (where you only realise gains/losses at sale), futures positions are settled daily. End of each trading day:
NSE calculates settlement price (typically last 30-min weighted average)
Your position is "marked" against the settlement price
Profit credited to your trading account; loss debited
Unaddressed margin call → broker squares position next morning
This daily settlement is why futures losses can spiral — accumulated overnight MTM losses can wipe out your margin before you've even had a chance to exit.
Cash vs Physical Settlement at Expiry
Cash Settlement
Index futures (Nifty, Bank Nifty, FinNifty): settled in cash at final settlement price
No physical delivery of stocks
Profit/loss credited/debited to trading account
Physical Settlement (SEBI 2018 Rule)
Stock futures (Reliance, HDFC Bank, etc.): MUST be physically settled at expiry if held to expiry
Long futures holders take delivery of shares; short holders deliver shares
Requires full contract value of cash or shares at expiry — most retail can't handle this
Most retail F&O traders close positions before expiry to avoid physical settlement obligations
Why Physical Settlement Matters:
If you're long a Reliance future bought at ₹3,000 (contract value ₹7.5 lakh), holding to expiry means you must pay ₹7.5 lakh and take 250 shares into your demat. Most retail accounts don't have that capital free. Failure to close OR pay results in penalty + auction settlement. Always close stock futures positions at least 1-2 days before expiry.
Contango vs Backwardation
Contango (Normal)
Futures price > Spot price. Reflects the "cost of carry" — interest on capital + dividend impact. Most stable markets show modest contango (futures premium ~0.5-1% above spot for near-month).
Backwardation
Futures price < Spot price. Signals immediate selling pressure or expected dividend. Can indicate stress or arbitrage opportunity.
The basis (futures price − spot price) converges to zero at expiry. Roll yield (positive or negative based on basis) is one strategy for systematic traders.
The SEBI 2024 Reality Check
SEBI's "Analysis of Profit and Loss of Individual Traders in Equity Derivatives" study (released 2024):
~91% of individual F&O traders incurred losses in FY24
Cumulative net losses of individual traders over 3 years: ₹1.81 lakh crore
Average loss per loss-making trader: ~₹50,000-1.5 lakh
Only ~1% of intraday F&O traders made profits exceeding ₹1 lakh after costs
The data is consistent across multiple years and segments. F&O is mathematically a wealth-destroying activity for the average retail participant.
When (Rarely) Futures Make Sense for Retail
Hedging existing portfolio: Own ₹50L equity portfolio; expect volatility around budget/elections — short Nifty futures to hedge. Costs the basis but caps drawdown.
Cash-futures arbitrage: Buy spot, sell futures when contango is high; capture ~1-1.5% per cycle. Requires sufficient capital.
Specific event positioning: Highly liquid, well-researched bet on a specific catalyst with strict stop loss.
If you don't have a specific reason matching above, you don't need futures. Cash equity (delivery) does the wealth creation job better with less risk.
Next Step — Options Contracts
Options offer more strategy variety than futures — calls, puts, spreads, straddles. Learn the basics, the asymmetric payoff structure, and why most retail options buyers also lose.
A futures contract is a standardised agreement to buy or sell an asset (stock, index, commodity) at a pre-agreed price on a specific future date (expiry). In Indian equity F&O, you trade futures on Nifty 50, Bank Nifty, FinNifty, Nifty Midcap, and ~180 individual stocks. Contracts are exchange-traded (NSE) with standardised lot sizes. You don't pay the full contract value upfront — only a margin (typically 10-25%). At expiry, contracts settle in cash (for index futures) or by physical delivery (for stock futures, per SEBI's 2018 rule).
F&O (Futures and Options) is the equity derivatives segment of Indian markets. It includes futures contracts and options contracts on Nifty 50, Bank Nifty, FinNifty, Nifty Midcap, sectoral indices, and ~180 individual stocks (NSE's F&O stock list, updated semi-annually). F&O is used for: (1) Hedging — protecting an existing portfolio. (2) Speculation — taking leveraged directional bets. (3) Arbitrage — exploiting price differences. SEBI's 2024 study showed ~91% of individual F&O traders lose money, primarily due to speculation gone wrong.
Lot size is the minimum quantity you can buy/sell in a futures contract — set by NSE for each underlying. Examples (illustrative, lot sizes are revised periodically): Nifty 50 = 25, Bank Nifty = 15, FinNifty = 25, Reliance ~250, HDFC Bank ~550, Infosys ~300. So one Nifty 50 futures contract represents 25 × Nifty value. At Nifty 25,000, contract value = ₹6.25 lakh. Margin requirement might be ₹1-1.5 lakh. SEBI revises lot sizes when the minimum contract value drifts too far from ~₹15-20 lakh (the target for retail accessibility). Check NSE's current lot size before trading.
When you trade futures, you don't pay full contract value — only margin. Two components. (1) SPAN margin: SEBI-defined, covers expected 1-day price movement (calculated by NSE's clearing corporation NCL based on volatility). (2) Exposure margin: additional cushion (3-5% of contract value typically). Total margin = SPAN + Exposure, typically 10-25% of contract value. Margin is calculated daily; if your position moves against you (mark-to-market loss), additional margin may be called. The leverage (4-10x effective) is what makes futures both exciting and dangerous for retail traders.
Mark-to-market (MTM) means your futures position's profit/loss is calculated daily and credited/debited to your trading account at end of day. If you're long Nifty futures and Nifty falls 100 points overnight, your account is debited 100 × lot size × number of lots immediately. This daily settlement prevents losses from accumulating to unmanageable levels. If MTM losses erode your margin below required level, broker issues margin call. If unaddressed, position is squared off. This is one major difference between futures and forwards (which settle only at expiry).
Generally no — SEBI's 2024 data shows 91% of individual F&O traders lose money, with cumulative retail F&O losses of ₹1.81 lakh crore over 3 years. The combination of leverage, mark-to-market pressure, and the difficulty of consistently predicting short-term direction makes futures structurally hard for retail. Use only if: (1) you have 5+ years of investing experience; (2) capital you can afford to lose entirely; (3) genuine hedging need (e.g., owning ₹50L portfolio + hedging with Nifty puts during expected volatility); (4) strict position sizing and stop loss discipline. Otherwise stick to cash equity.
