How Futures Trading Works in India: Lot Size, Margin, Expiry

A practical, step-by-step guide to actually placing a Futures trade in India — contract selection, lot size, margin, order types, and the expiry cycle.

What you will learn in this lesson

  • Understand the practical steps to place a real Futures trade in India
  • Learn how monthly expiry cycles work, and what "near month" and "far month" mean
  • Understand how to read a Futures contract's specifications before trading it
  • Learn the difference between market orders and limit orders in an F&O context
  • Know what F&O segment activation requires, beyond a basic trading account

You understand what a Futures contract is and how profit/loss works. This lesson fills in the practical, real-world layer: what you actually need to set up, how contract expiry cycles work in India, and how to actually place a trade.

Step 1: F&O Segment Activation

Before you can trade Futures (or Options) in India, your broker needs to activate F&O segment access on your trading account — a distinct step from the basic equity trading access you’d have used to buy stocks in earlier lessons.

This typically involves:

  • Acknowledging specific risk disclosures related to derivatives trading (a regulatory requirement, not just a formality)
  • In some cases, providing income proof or net-worth documentation
  • A brief waiting period for the broker to process the activation

This is a deliberate friction point, by design — SEBI and brokers want to ensure traders are making an informed, active choice before accessing a segment with meaningfully different risk characteristics than plain equity investing.

Step 2: Understanding Expiry Cycles — Near, Next, and Far Month

For most F&O instruments, exchanges list three monthly contracts simultaneously:

   Near Month          Next Month           Far Month
  (current month's    (one month           (two months
   expiry — soonest)   further out)         further out)
        │                    │                    │
        ▼                    ▼                    ▼
   Trades until          Trades until         Trades until
   its own expiry        its own expiry       its own expiry

All three trade at the same time, typically at slightly different prices (explained fully in the next lesson via “cost of carry”). Most retail trading activity concentrates in the near month contract, since it usually has the highest liquidity — but a trader can choose any of the three based on their intended holding period.

Step 3: Choosing Your Order Type

When placing a Futures order, you’ll typically choose between:

Order Type What It Does Best For
Market Order Executes immediately at the best currently available price When speed matters most, and you accept some price uncertainty
Limit Order Executes only at your specified price or better When price control matters most; may not execute if price never reaches your level

In less liquid contracts, or during volatile periods, market orders can execute at a noticeably worse price than expected (called “slippage”) — a limit order avoids this risk, at the cost of possibly not executing at all.

Step 4: Rollover — Extending Your Position Beyond One Expiry

If you want to maintain a position beyond the current month’s expiry, you don’t wait for automatic settlement — instead, you typically roll over: closing your near month position and simultaneously opening an equivalent position in the next month’s contract.

   Close Near Month Position   +   Open Next Month Position
             │                                │
             └──────────► Same net exposure ◄─┘
                        (continued, just in a
                         different contract)

Rollover is a common, deliberate choice — not something forced on every trader, since plenty of positions are opened and closed well within a single expiry cycle.

Real-Life Example: Placing a Futures Trade, Step by Step

  1. You’ve completed F&O segment activation with your broker.
  2. You open your broker’s app and search for the Nifty 50 Futures contract, near month expiry.
  3. You check the current price, lot size, and required margin (using your broker’s live margin calculator, as covered in Lesson 9).
  4. You confirm you have sufficient funds in your trading account to cover the margin requirement.
  5. You place your order — say, a limit order to go long 1 lot at a specific price.
  6. Once matched, your position appears in your account, subject to daily mark-to-market until you close it or it expires.
  7. You monitor the position and decide, before expiry, whether to close it, roll it over, or (for cash-settled contracts) let it settle automatically.

Common Beginner Mistakes

  • Skipping F&O segment activation research, and being confused when a Futures order gets rejected due to missing segment access.
  • Always defaulting to market orders, without considering that a limit order might better protect against slippage, especially in less liquid contracts.
  • Not checking which expiry month a contract belongs to before trading it — accidentally trading a far month contract with lower liquidity when the near month was intended, or vice versa.
  • Assuming you must let every position run to expiry. Most traders actively manage and close positions well before that point.
  • Ignoring brokerage, STT, and other charges when estimating potential profit, leading to inflated expectations compared to actual net results.

Practical Tips

  • Before your first live Futures trade, do a complete “dry run” on your broker’s app: search the contract, check the margin calculator, and note the exact lot size and expiry — without placing the actual order — until the process feels familiar.
  • Default to limit orders when you’re still building confidence, especially in less liquid contracts, to avoid unexpected slippage.
  • Set a calendar reminder a few days before any expiry you’re holding a position in, so rollover or exit decisions aren’t made in a last-minute rush.
  • Always cross-check contract specifications (lot size, margin) directly from your broker’s app or NSE’s official website immediately before trading — these figures can change, and outdated information leads to costly mistakes.

Practical Exercise

  • On your broker's app (without placing a real trade), search for a stock or index Futures contract and note: the current month, next month, and far month contracts available, their respective prices, and their lot sizes. Observe how the price differs slightly across the three expiries.
  • Write out, step by step in your own words, exactly what you would need to check and do — in order — before placing your very first real Futures trade. Compare your list against the checklist in this lesson's "Practical Tips" section.

Mini Quiz

1. In India, how many expiry cycles are typically available for a given Futures contract at once?
  • Only one, the current month
  • Usually three — near month, next month, and far month
  • Twelve, one for every month of the year, always
  • It depends only on the trader's broker

Exchanges typically list three monthly contracts at a time for most F&O instruments — the current ("near") month, the next month, and the far month — giving traders a choice of expiry.

2. What does "F&O segment activation" mean?
  • A one-time government tax registration
  • A separate approval/activation step with your broker, beyond a basic equity trading account, required before you can trade Futures and Options
  • A feature only available to institutional traders
  • The same thing as opening a Demat account

Most Indian brokers require a separate F&O segment activation (sometimes involving income proof and a risk disclosure acknowledgment) before allowing Futures/Options trading, distinct from basic equity trading access.

3. What is the key difference between a market order and a limit order?
  • A market order executes at the best currently available price; a limit order only executes at your specified price or better
  • They are identical in every way
  • A limit order always executes faster than a market order
  • Market orders are only for Options, limit orders only for Futures

A market order prioritizes speed of execution at the best available price; a limit order prioritizes price control, only executing at your specified price or better (which may mean it doesn't execute at all if the price never reaches it).

4. Why might a trader choose the "far month" contract instead of the "near month" contract?
  • Far month contracts are always cheaper
  • To hold a position over a longer time horizon without needing to roll over as soon
  • Far month contracts have no margin requirement
  • It's required by SEBI for beginners

Choosing a far month contract lets a trader maintain exposure over a longer period without needing to close and re-open (roll over) the position as expiry approaches.

5. What typically happens to a Futures contract's trading activity as its expiry date approaches?
  • Trading always stops a week early
  • Volume and focus often shift toward the next month's contract, as traders roll over or exit ahead of expiry
  • Margin requirements always drop to zero
  • Nothing changes at all

As expiry nears, many traders roll over to the next month's contract or close their position, so trading activity commonly shifts toward the next expiry cycle.

6. Where can you check exact, current contract specifications (lot size, margin, expiry) for a specific Futures contract?
  • Only by calling SEBI directly
  • On the exchange's official website (like NSE) or your broker's contract information page
  • They are never published and must be estimated
  • Only available to institutional clients

NSE and BSE publish exact, current contract specifications publicly, and brokers typically surface this same information directly within their trading platforms.

7. Is F&O trading available to every stock listed on NSE or BSE?
  • Yes, every listed stock automatically has Futures and Options
  • No — only a specific, exchange-approved list of stocks (meeting liquidity and other eligibility criteria) have F&O contracts available
  • Only for banking stocks
  • Only for companies older than 10 years

Only stocks that meet specific exchange eligibility criteria (liquidity, market cap, and other factors) are approved for F&O trading — not every listed company has tradeable Futures or Options.

Frequently Asked Questions

What do I need, beyond a regular Demat and trading account, to trade Futures in India?

You typically need your broker to activate "F&O segment" access on your trading account — a separate step from basic equity trading, which may require additional documentation (like income proof) and an acknowledgment of the risks involved, per SEBI's investor protection framework.

What's the difference between "near month," "next month," and "far month" Futures contracts?

These refer to the three monthly expiry cycles typically available for a given F&O instrument at any time — near month is the current/soonest expiry, next month is one month further out, and far month is two months out. All three trade simultaneously, at slightly different prices, giving traders a choice of time horizon.

How do I choose between a market order and a limit order for a Futures trade?

Use a market order when speed of execution matters most and you're comfortable with the current best available price. Use a limit order when price control matters more than immediate execution — useful in less liquid contracts or during volatile periods, where market orders can execute at a meaningfully worse price than expected.

What is "rollover," and why do traders do it?

Rollover means closing your position in the current month's expiring contract and simultaneously opening an equivalent position in the next month's contract, to maintain continued exposure without going through settlement. Traders roll over when they want to keep a position open longer than the current contract's remaining life allows.

Can I trade Futures on any stock I want?

No — only stocks that meet NSE/BSE's specific eligibility criteria (liquidity, market capitalization, and other factors, reviewed periodically) have Futures contracts available. Index Futures (Nifty, Bank Nifty, Sensex) are available regardless, since they're based on the index itself, not a single company.

Do Futures prices for near month, next month, and far month always match each other?

No, they typically differ slightly, largely due to the "cost of carry" concept — covered fully in the next lesson — which explains why a Futures contract expiring further in the future often has a different price than one expiring sooner.

What's the risk of holding a Futures position until expiry, versus closing it early?

Holding until expiry means your position gets automatically settled per the contract's rules (cash or physical settlement), at the final settlement price — you lose control over the exact exit price/timing. Most active traders prefer to close positions on their own terms before expiry, giving them more control, though it's not mandatory.

Is Futures trading available throughout the entire trading day?

Yes, Futures contracts trade throughout normal market hours (broadly 9:15 AM to 3:30 PM on NSE for equity derivatives), just like the underlying stock or index itself, subject to any circuit limits that might pause trading temporarily.

How do brokerage and other charges affect Futures trading compared to what this course's examples show?

This course's examples generally focus on the core mechanics (price movement, margin, P&L) without including brokerage, exchange transaction charges, Securities Transaction Tax (STT), and GST, all of which apply to real trades and reduce net profit (or add to net loss). We cover the full cost structure in Module 23 (Broker Selection).

Can beginners realistically start with Futures trading, or should they start with something else?

Futures carry meaningful risk due to leverage and uncapped potential loss on both sides, so many beginners are better served starting with a strong grasp of the mechanics (which this course provides), extremely small position sizes, and disciplined risk management (Module 14) before scaling up — regardless of which specific instrument (Futures or Options) they eventually focus on.

Glossary

Key Takeaways

  • Trading Futures in India requires a separate F&O segment activation on your trading account, beyond basic equity access.
  • Exchanges typically list three monthly expiry cycles at once — near month, next month, and far month — each trading at a slightly different price.
  • A market order prioritizes speed of execution; a limit order prioritizes price control — the right choice depends on the situation.
  • Rollover means closing a position in the expiring contract and opening an equivalent one in the next month's contract, to maintain exposure without settling.
  • Only exchange-approved, eligible stocks have Futures contracts available — not every listed company qualifies.
  • Real trades involve brokerage, STT, and other charges beyond the core price-movement P&L shown in simplified examples.

Conclusion

With this lesson, you've moved from understanding Futures conceptually to understanding exactly how they're practically traded in India — contract selection across expiry cycles, order types, and the account setup required. One piece is still missing: why does a Futures contract's price often differ from the underlying's spot price, and why do near month, next month, and far month contracts all trade at slightly different prices? That's exactly what the next lesson — Futures pricing and cost of carry — explains.
