Margin Trading
Trading on margin means borrowing funds from a broker to purchase securities. You only pay a certain percentage (or margin) of the value. This allows you to trade beyond your own available funds. The leverage is provided by the broker, who extends you a loan to open the position(s). In this way, leverage is created, which can be used to increase profits. Thus, the advantage of trading on margin is that it can increase potential profits by taking larger positions. This also means that your potential losses can be substantially higher if the positions do not have the desired results, and you may lose more than your initial investment. Moreover, because you borrow funds, you are responsible for repaying the loan plus interest to the broker.
Trading on margin is only for experienced investors with a high risk tolerance. You may lose more than your initial investment.
A simple example
You currently possess €3,000 in cash and intend to acquire €10,000 worth of stocks. To achieve this, you have two options:
- Option one involves transferring additional funds to your account, waiting for their processing, and then proceeding with the stock purchase.
- Alternatively, you can choose to allow your broker to use your existing cash as collateral, thus granting you access to the necessary additional funds for the €10,000 purchase. In this case, the broker will request a collateral, also known as an initial margin, of €3,000. The remaining amount of €7,000 is lent to you by the broker. On the €7,000 you borrowed you pay debit interest, calculated on the same day.
Margin trading allows you to take on greater obligations without having the corresponding cash on hand.
Now let’s assume the stock you bought worth €10,000 goes up by 1% and is now worth €10,100. The gain of €100 is all yours. What does this mean for your equity? It rises from €3,000 to €3,100. This is an increase of (€100/€3000) = 3.33% although the stock price only increased by 1%.
Now, consider a scenario where the stock you purchased for €10,000 decreases by 1% and is now worth €9,900. The loss of €100 is entirely on you. What does this mean for your equity? It drops from €3,000 to €2,900. This is a decrease of (€100/€3,000) = 3.33%, even though the stock price only decreased by 1%.
| Trading with only your own funds | Trading on Margin | |
|---|---|---|
| Initial Deposit | €3,000 | €3,000 |
| Available to invest | €3,000 | €10,000 |
| Purchase | €3,000 | €10,000 |
| Remaining available funds | €0 | €0 |
| Profit/Loss from Investment (1% increase/decrease) | (-) €30 | (-) €100 |
| Return on your capital | (-) 1.00% | (-) 3.00% |
Note: This example does not take transactional costs or financing costs (debit interest) into account.
How does trading on margin work?
A margin account empowers you to engage in trading with additional funds, allowing you to take larger positions, thus increasing your available capital beyond your initial cash amount. Trading platforms provide clear insights into the advantages of using this approach.
- A negative cash balance indicates that you are borrowing funds to facilitate your trades. In that case, you will pay debit interest on your negative cash balance.
- You can leverage your available funds by using your securities as collateral, enabling you to access additional cash for your trading activities.
When making a purchase, such as €10,000, you’ll only need to provide a fraction of that value as collateral, commonly referred to as the Initial Margin.
Any margin account whose value decreases below €2,000 (or equivalent) will automatically be considered a cash account. Thus, if you have a margin account, but the value falls below €2,000, you will no longer be able to trade on margin, for example, when writing options.
Pros and cons of a margin account
- A margin account provides the ability to invest in leveraged products such as turbos, sprinters and speeders.*
- The use of margin allows investors to achieve meaningful results even with less volatile products.*
- A margin account allows investors to sell (write) options.*
- A margin account allows investors to go short on stocks.*
- Investors can trade futures with a margin account.*
- In margin trading, both profits and losses are magnified, meaning you can lose more than your personal investment.
- Failure to meet maintenance margin can result in forced liquidations of positions in your investment portfolio.
- Like borrowing money, trading on margin is not without cost. You pay debit interest on the borrowed amount.
- Using leverage can increase the complexity of managing your investment portfolio.
- Your loss may be greater than your deposit.
* Provided that your account balance and trading experience permits this.

Risk-based Margin Overview
For European residents trading stocks, risk-based margin applies. This margin system evaluates your portfolio’s risk to determine margin requirements, allowing for greater leverage through more accurate risk assessments.
Risk-Based Margin
- Simulates market movements to evaluate potential outcomes and risks.
- Provides a more tailored margin model, enabling increased leverage for investors.
Offsetting Correlated Risks
- Within a single underlying group, gains and losses can offset each other.
- Example: If a portfolio holds a long stock position and a long put option on the same stock, losses on the stock due to a market drop can be offset by gains on the put option.
Eligibility Requirements
- Vary based on the investor’s region, personal details, and exchange rules.
Eligible Positions
- Include a wide range of equity securities and derivatives, such as foreign equities, options, security futures, warrants, and index-based instruments.
This system allows for precise risk management and optimized use of margin across diverse portfolios.
For European residents trading options, risk-based margin applies. This approach assesses portfolio risk to determine margin requirements, enabling investors to manage leverage more effectively.

For European residents trading Futures & FOPs, risk-based margin applies. This approach assesses portfolio risk to determine margin requirements, enabling investors to manage leverage more effectively.
Futures margin requirements are based on risk-based algorithms. All margin requirements are expressed in the currency of the traded product and can change frequently. Risk-based margin algorithms define a standard set of market outcome scenarios with a one-day time horizon. A price scanning range is defined for each product by the respective clearing house.
Note that for commodities including futures, single-stock futures and futures options, margin is the amount of cash a client must put up as collateral to support a futures contract. For securities, margin is the amount of cash a client borrows.
Margin requirements for futures are set by each exchange.
You can find more information an overview of the margin requirements for Futures & FOPs on the following page:

The European Securities and Markets Authority (ESMA) has issued new rules for trading CFDs for retail investors, effective from 1 August 2018. The AFM and other national regulatory authorities have implemented the ESMA regulations. This section will examine these new regulations and their implementation. These regulations do not affect professional clients.
The new laws and regulations require you to use a multiple account structure with a separate CFD segment. You are not allowed to use securities in your account as collateral for your CFD positions. We have included a separate CFD segment in your account to comply with these requirements. You can check this in the account window of the Trader Workstation (TWS) and the LYNX Trading App.

Metals Margin Requirements | Interactive Brokers Ireland
For equities, ETFs and exchange-traded funds, the margin requirement is usually 15% to 100% of the value of the position. The margin requirement for short positions ranges between 30% and 100% of their value.
| Long options |
| up to 100% of the premium paid will be required as margin. However, depending on the contract’s duration and liquidity, IB may impose stricter requirements. |
| Short call |
| No margin is required if it is a covered call option. If the short call option is not covered, the system performs a simulation of various scenarios and determines the required margin based on the maximum possible loss. |
| Short put |
| This option strategy requires at most the margin required for the allocation of the put. For example: a stock from company A has a value of 100 USD. If a margin of 50% is required for the stock, a margin of 5,000 USD is required for a position of 100 stocks. Therefore, if you sell a put, the maximum required margin is 5,000 USD, which is the same amount required for buying 100 stocks. |
| Credit spreads |
| For credit spreads, at most the difference between the two strike prices multiplied by the value of the underlying asset, minus the value of the premium received for this credit spread, is required as margin. Let’s take a 100/95 bull put spread as an example. This is a credit spread where the 100 put is sold and the 95 put is bought, resulting in the seller receiving a premium (credit). Assuming you receive $2.50, or a total of $250 ($2.50 * 100 shares per contract), the calculation of the required margin would be as follows: 5 USD (difference between the two strikes) * 100 (per contract) = 500 USD. 500 USD – 250 USD (received bonus) = 250 USD The maximum margin for this position is therefore $250 USD. |

Options and structured products generally require an initial margin of 100% of the market value. In some cases, this may deviate due to risk-based margin calculation.
The margin requirements for spot gold (XAUUSD) and spot silver (XAGUSD) are as follows:
The calculation of margin in theory
Interactive Brokers uses a risk-based model called Portfolio Margin to determine margin requirements based on historical volatility. There are different calculation methods depending on the product, two of which we explain here:
Both are mathematical methods to simulate various scenarios for your portfolio and calculate the risks of options and futures:
- TIMS scans your entire portfolio to analyze risks and simulates the two largest positions at ± 30% and all others at ± 5% to examine the risk of low diversification. The calculation also considers the impact of extreme price fluctuations and high concentration of risk. Therefore, changes in implied volatility of options, large positions, and remaining days until expiry have an impact, too. Please be aware that the initial margin requirement is usually higher than the minimum maintenance margin requirement.
- In contrast, the Singleton Margin Method calculates the margin requirements for small-cap stocks with market capitalization of less than $500 million. It enables the simulation of price fluctuations, with an increase of 30% and a decrease of 25%. The system selects the scenario with the highest possible loss and applies it as a requirement for your portfolio. Margin requirements for stocks typically range from 15-30% of the market value depending on the calculation.
The Chicago Mercantile Exchange (CME) developed SPAN as a risk-based method for calculating margin requirements for futures and futures options. Then, test your portfolio under hypothetical scenarios to examine price changes and the implied volatility of options. We use “in-house scenarios” to examine extreme price fluctuations and their impact on out-of-the-money options. We choose the scenario with the greatest possible loss as the margin requirement.
FAQ
If you want to trade on margin, you can upgrade your cash account to a margin account at no extra cost. However, borrowing funds accrue interest which you need to pay.
You should go to the Client Portal and select Settings. Then, navigate to the Account Configuration section and click on Account Type. Now, you can continue by providing your current experience with margin trading and then sign the margin risk disclosure. For detailed instructions, click here.
Interactive Brokers does not issue margin calls, so liquidates assets when the margin threshold is reached. Accounts receive real-time Margin Warning information.
No, you will not receive a notification prior to a margin liquidation. It is your responsibility to monitor your account and ensure it meets margin requirements at all times. Post-liquidation notifications are also not guaranteed. However, you can manually set up trade alerts to stay informed about account activities, including liquidations.
To help you stay on top of your margin requirements, we provide color-coded account information to notify you that you are approaching a serious margin deficiency. TWS will highlight the row whose value is in the distress state. The colors on your account screen tell you the following:
- Yellow: You have only a 10% cushion above the margin requirement. If your account equity moves rapidly from a greater than 10% cushion to a margin violation, your positions may be liquidated without you receiving a yellow warning.
- Orange: Your margin cushion is depleted and you have a short time to enter into margin-reducing trades before your positions are liquidated. At this point you will not be able to enter into any trades that might increase your margin.
- Red: Your positions will shortly start to be liquidated as necessary to bring your account back within the margin limits.
Generally, it is not necessary to trade on margin. Albeit, some products require you to upgrade to that account type:
- Futures
- CFDs
- Short options and certain option strategies
You must be at least 21 years old to trade on margin. The deposit value (net liquidation value) must be at least €2,000. If the deposit value is lower, you will automatically trade as with a cash account. You can read more about our minimum requirements on the page of your local branch.
You cannot buy all financial instruments on margin. Risk assets like Penny Stocks, Warrants, and issuer products often demand payment with 100% of your own funds.
The exchanges and the broker itself define the requirements for initial margin and maintenance margin. Generally, the margin requirements change once per day, but this can change. Additionally, some future contracts have particularly low intraday margin requirements.
If you wish to free up more available liquidity to protect yourself from further future declines, there are several actions you can take:
- You can transfer funds to your trading account. To do this, you can use the deposit instructions.
- You can execute an order that lowers your current margin requirements. In most cases this means you can close or reduce a current open position. You can perform an internal transfer from other accounts linked to your securities account
- In TWS you can right-click on a position in your portfolio and subsequently select the “Set Liquidate Last” parameter. If you can’t see this parameter, you can look it up via the search bar on top of the pop-up menu.
If possible, the system will try to protect these positions when a liquidation occurs on your account. However, there is no guarantee that these position(s) will also effectively not be liquidated earlier by the system.
