In active trading especially in Futures and Options (F&O) the term MTM (Mark-to-Market) often appears on your contract notes, broker ledger, and daily P&L statements. But what does MTM really mean, and why does it impact your trading balance even if you haven’t closed your position? In this blog, we’ll break down MTM in simple terms, explain how it is calculated, and show why understanding MTM is essential for managing margins, risk, and cash flow in the Indian stock market.  

What is MTM (Mark-to-Market)?

Mark-to-Market (MTM) refers to the daily adjustment of the value of an open position in futures contracts, based on the closing price of the asset at the end of the trading day. In simple terms:

• If the market moves in your favor, your account is credited (profit).
• If it moves against you, your account is debited (loss).

This process ensures that gains and losses are realized every day instead of only on the final day of the contract.  

Why is MTM Important?

• Daily Profit and Loss Tracking: Helps track real-time gains/losses, even without closing positions.
• Margin Requirement Adjustments: Brokers collect/return funds based on MTM—impacting your margin availability.
• Risk Containment: Prevents massive losses by settling contracts incrementally each day.

MTM is mandatory for all futures contracts as per SEBI and exchange rules (NSE/BSE).  

MTM Calculation: A Simple Example

Let’s say you buy 1 lot of Nifty Futures (50 units) at ₹22,000.

Day 1 (Trade Day)

• You buy Nifty Futures @ ₹22,000
• Closing price: ₹22,050
• MTM Profit = (₹22,050 - ₹22,000) × 50 = ₹2,500 → Broker credits ₹2,500 to your ledger.

Day 2

• Opening price irrelevant for MTM.
• New closing price: ₹21,800
• MTM Loss = (₹21,800 - ₹22,050) × 50 = -₹12,500 → Broker debits ₹12,500 from your ledger (margin shortfall may arise).

Day 3

• Closing price: ₹22,100
• MTM Profit = (₹22,100 - ₹21,800) × 50 = ₹15,000 → Broker credits ₹15,000

Note: Only the difference from the previous day's closing price is considered. This continues until you close the position or until expiry.  

How MTM Affects Your Trading Ledger

Your broker’s ledger reflects the MTM amount daily, either as:

• MTM Credit (profit added to free balance)
• MTM Debit (loss deducted, may require margin top-up)

In high volatility periods, traders may see significant fluctuations in ledger balance due to MTM—even if they have not taken any new trades.  

MTM vs Realized Profit

 

Concept	Meaning	When It Occurs
MTM (Unrealized)	Daily revaluation of open futures	End of each trading day
Realized Profit/Loss	Final profit/loss when position is closed	When position is squared off

So, MTM is not the final profit, but a reflection of your day-by-day gain or loss.  

MTM in Options Trading

MTM is not applied on Options like it is in Futures.

• Buyers of Options: Pay the premium upfront—no daily MTM.
• Sellers (Writers): May face margin adjustments based on price changes, but not direct MTM in the same way as futures.

 

MTM and Margin Shortfall

Daily MTM losses reduce your free margin. If your account balance falls below the required margin, you may get:

• Margin Call: Request to add funds.
• Auto Square-off: Broker closes position to limit further risk.

Tip: Always maintain margin buffer (5–10%) above required margin to avoid forced exits.  

Key Takeaways

• MTM is the daily settlement of futures contracts based on price changes.
• It directly affects your ledger balance, even for open trades.
• Understanding MTM is essential for margin management and avoiding forced liquidations.
• Always monitor MTM impact if you're actively trading index or stock futures in NSE or BSE.

 

FAQs

 

1. Do I pay MTM even if I don’t close my position?

Yes. MTM is applied daily, even if you carry your futures position overnight. You’ll either get credited or debited based on the day’s price movement.

2. Where can I check MTM values for my trades?

Your broker’s back office or trading platform ledger (e.g., RMoney, etc.) shows daily MTM statements.

3. Can MTM cause my position to be squared off?

Yes. If cumulative MTM loss reduces your margin below the required level, the broker can square off your position to limit risk.

4. Does MTM apply on Options too?

Not in the same way. Option buyers don't have MTM. Option sellers may have margin adjustments, but it's not MTM like in futures.

5. Is MTM taxable as profit/loss?

Yes. MTM gains/losses in F&O are considered business income/loss under the Income Tax Act and must be reported when filing ITR.
