Margin & Mark to Market (M2M)

After learning about leverage, Rajesh looked thoughtful.

“Priya, I understand that I only pay the margin. But what happens after I enter the trade? Do I just wait till I exit?”

Priya shook her head.

“No. Futures trading does not work like that. Your profit and loss are calculated every day.”

Rajesh looked surprised.

“Every day?”

“Yes,” Priya said. “That is called Mark to Market, or M2M.”

Why Margins Are Required

Priya began with the basics.

“In futures trading, both buyer and seller are taking risks.”

To ensure that neither party defaults:

• Both must deposit a margin
• Margin acts as a security deposit

Rajesh said, “So margin protects the system?”

“Exactly,” Priya replied.

Types of Margins (Basic Understanding)

Priya simplified the idea.

When you enter a futures trade, you need:

• Initial margin → to start the trade
• Maintenance margin → minimum balance to continue

If your balance falls below the required level, action is taken.

What is Mark to Market (M2M)?

Rajesh asked, “Now explain M2M.”

Priya explained clearly.

Mark to Market means:

• Profit or loss is calculated daily
• Based on daily closing price
• Money is adjusted in your account

How M2M Works

Priya broke it down.

At the end of each trading day:

• If the price moves in your favor → profit is credited
• If price moves against you → loss is deducted

Rajesh said, “So I don’t have to wait till the end?”

“Exactly,” Priya said. “Settlement happens daily.”

Why Daily Settlement is Important

Priya explained.

Daily settlement ensures:

• No accumulation of huge losses
• Reduced default risk
• System stability

Rajesh nodded.

“So risk is controlled step by step.”

“Correct.”

What is a Margin Call?

Rajesh asked, “What happens if I keep losing?”

Priya explained.

If your losses reduce your margin below the required level:

• You get a margin call

This means:

• You must add more funds
• Otherwise, your position may be closed

Rajesh looked serious.

“So I can be forced to exit?”

“Yes,” Priya said. “If you don’t maintain margin.”

Example of Margin Impact (Conceptual)

Priya explained without numbers.

• You enter a futures trade
• Price moves against you
• Loss is deducted daily
• Your margin keeps reducing

If losses continue:

• Margin falls below the required level
• Broker asks for additional funds

Margin from a Bigger Perspective

Priya added an important insight.

“Margins are not just for traders — they protect the entire market.”

They ensure:

• Discipline
• Stability
• Trust in the system

Key Risk to Understand

Rajesh said, “So even if I don’t exit, losses are still realised daily.”

“Exactly,” Priya replied.

“This is why futures trading feels fast and intense.”

Common Mistakes by Beginners

Priya warned.

Many beginners think:

“I will hold and recover losses later.”

But in futures:

• Losses are adjusted daily
• Margin may run out quickly

Rajesh said, “Now I understand why margin is so important.”

Priya nodded.

“Yes. Margin is the backbone of futures trading.”

Rajesh added, “And M2M ensures everything stays balanced daily.”

“Exactly,” Priya said.

• It acts as a security deposit for both parties
• Mark to Market (M2M) calculates profit/loss daily
• Gains are credited, and losses are deducted every day
• Daily settlement reduces risk in the system
• Margin call occurs when funds fall below the required level
• Failure to maintain the margin can lead to a forced exit
• Futures trading requires active monitoring of positions
