Understanding Used Margin in Forex Trading

What is Used Margin?

When trading forex, margin plays a crucial role in determining how much capital you need to keep positions open. Used Margin refers to the total amount of margin that is currently being utilized across all open positions. Unlike Required Margin, which applies to a single trade, Used Margin accounts for all positions combined.

👉 Think of Used Margin as the portion of your trading funds that is “locked up” and unavailable for opening new positions.

How Used Margin Works

To better understand Used Margin, let’s first recap Required Margin:

• Every time you open a trade, a specific amount of Required Margin is set aside.
• If you have multiple open positions, each trade has its own Required Margin.
• The sum of all Required Margin across open trades is what we call Used Margin.

Example: Calculating Used Margin

Let’s say you deposit $1,000 in your trading account and decide to open two positions:

1️⃣ Buy 1 Mini Lot (10,000 units) of USD/JPY
2️⃣ Buy 1 Mini Lot (10,000 units) of USD/CHF

Each currency pair has its own Margin Requirement:

Currency Pair	Margin Requirement
USD/JPY	4%
USD/CHF	3%

Step 1: Calculate Required Margin for Each Trade

✅ For USD/JPY:

• Notional Value = $10,000
• Required Margin = $10,000 × 4% = $400

✅ For USD/CHF:

• Notional Value = $10,000
• Required Margin = $10,000 × 3% = $300

Step 2: Calculate Used Margin

Since both trades are open simultaneously, the Used Margin is:

📌 Used Margin = Required Margin for USD/JPY + Required Margin for USD/CHF
📌 $400 + $300 = $700

This means $700 of your $1,000 account balance is being used to maintain open trades.
