Working Margin: Understanding Its Role in Keeping Trading Positions Open

When trading financial instruments such as forex (FX), contracts for difference (CFDs), stocks, or indices, understanding the concept of margin is crucial. One important term that often comes up is “working margin.” While many traders grasp the basic idea of margin as the collateral needed to open a position, working margin refers more specifically to the margin level available to keep existing positions open after trades have been executed.

In simple terms, working margin is the amount of margin currently being used to maintain your open positions. It represents the funds locked up to support your trades, ensuring you meet the broker’s requirements while keeping your positions active. If the working margin falls below a certain threshold, it can trigger margin calls or forced liquidation of positions.

How working margin fits into your trading account

When you open a trading position, your broker requires you to deposit a certain amount of funds as initial margin. This is a fraction of the total trade size, often expressed as a percentage (leverage). Once the trade is open, the broker monitors your account to ensure you have enough available margin to keep the position active. The working margin is the margin currently allocated to your open positions, calculated as part of your used margin.

Formulaically, working margin can be thought of as:

Working Margin = Initial Margin + Additional Margin (if applicable)

Or, in a more practical sense:

Working Margin = Used Margin = Sum of margin requirements for all open positions

For example, if you open two CFD positions, one requiring $500 margin and the other $300, your working margin would be $800. This amount is not available for opening new trades or withdrawing; it is held as collateral.

Real-life example

Imagine you’re trading the EUR/USD forex pair with a leverage of 1:30. You decide to buy one standard lot (100,000 units) at an exchange rate of 1.2000. The initial margin required might be roughly 3.33% of the position size due to the 1:30 leverage.

Position size: 100,000 EUR x 1.2000 USD = $120,000
Initial margin required = $120,000 / 30 = $4,000

This $4,000 becomes your working margin for this position. If your trading account balance is $10,000, after opening this trade, your free margin (available margin) would be $10,000 – $4,000 = $6,000.

Now, suppose the market moves against you, causing your unrealized losses to increase. If your equity (account balance plus unrealized profits/losses) decreases to a point where the free margin is too low, your broker may issue a margin call or close your position to prevent further losses. This is why monitoring working margin is essential for risk management.

Common misconceptions and mistakes

One common misunderstanding is confusing working margin with free margin. Free margin is the amount of funds left in your account that is not tied up in margin and can be used to open new positions or absorb losses. Working margin, on the other hand, is the margin locked to maintain current trades.

Another mistake traders make is ignoring how unrealized losses impact working margin. Even though your initial margin is fixed when opening a trade, losses reduce your equity and free margin, increasing the risk of margin calls. Some traders assume that once a position is open, the margin requirement remains constant regardless of price movements, which is not the case.

Additionally, traders sometimes over-leverage, using too much of their available margin, leaving little free margin to absorb adverse moves. This can quickly lead to forced liquidation of positions when the working margin requirement is not met.
