What is a contract for difference (CFD)?

Contracts for Difference (CFD) are popular albeit specialist financial derivative products that allow you to trade on the price movements of financial assets like Forex, Index Futures, Commodity Futures, Cryptocurrencies, Stocks and Exchange Funds.

They allow customers to trade freely without having to actually own the underlying asset or acquire any right or obligation. The main benefit of trading with CFDs is the flexibility they offer in terms of enabling you to trade against share movements without buying or selling the physical instrument.

Learn about the benefits and drawbacks of this powerful market instrument and how to use it to your advantage.

What are CFDs?

A CFD, or Contract for Difference, is essentially a contract between an investor and an intermediary (broker or investment bank). The intermediary bills or pays the difference between the price at which the trade is opened and the current market price, until the position is closed.

At the end of each day, if a position is showing a profit for the day, that profit is credited to your trading account. If the position is showing a loss for the day, the loss is debited from your account.

CFDs have no fixed maturity, meaning that the contract entered into between the intermediary and client has no end date. Instead, the client is able to terminate the contract whenever he or she chooses. This characteristic is one of the major benefits of this product over traditional futures.

Put simply, CFDs are financial instruments derived from other financial instruments that enable investors to get a potential profit from price movements without requiring them to own the physical asset. The underlying asset might be an index, a commodity, a precious metal, shares, etc.

How do CFDs work?

CFDs allow you to invest both in the rise and fall of a given asset. If we do an upside investment (we open a long position), we will have as profit the upwards difference in the price of the stock (e.g. if we open a $10 position and close it at $11, the profit would be one dollar since there is an upwards difference: $11 - $10 = $1).

If, however, we choose to complete a downside investment (we open a short position), our profit will be the difference between the contract settlement price and the closing price (e.g. if we open a $10 position and close at $9, the profit would still be one dollar as there is a difference to the downside)

The calculation will always be the same: sell price - buy price. A trade will generate a profit whenever the sell price is higher than the buy price.

Note: This calculation does not include any broker commission and/or financing expenses which pay be payable

Thus, CFDs enable traders to make profit irrespective of the market situation, i.e. both in markets that are on the rise as well as in down trending markets. It goes without saying that if we open a bearish position and the market behaves contrary to our predictions (i.e. it rises instead of falls), then we will incur a loss. The same would apply if we open a long position and the market falls.

What are margin and leverage?

Money and time on the libra

Perhaps a better question would be: what is the relationship between margin and leverage?

Margin is a good faith deposit required to maintain open positions.


Leverage is a by-product of margin and allows an individual to control larger trade sizes.

"Leverage" and "margin" essentially refer to the same concept, only from a slightly different angle. When a trader opens a position, they are required to provide a fraction of its value as a gesture of "good faith".

Leverage allows a trader to trade CFDs worth more than the margin they have deposited. In effect, the broker is lending capital to the client so that they can trade larger positions. The minimum amount that must be charged is known as the "Margin Requirement".

CFDs are a leveraged product, which means that you only need to deposit a small percentage of the total trade value in order to open a position. In other words, you only need put up a small amount of money to control a much larger amount, thus enabling you to increase the potential return on your investment. But don't forget that this means that your loss potential will be similarly amplified, so you must be sure to manage this additional risk.

Example of leverage and margin in action

You want to open a long position with CFDs on stock XYZ. The stock price is $20, and the margin requirement is 10%. That means you need to deposit margin of $2 for each CFD.

If you buy 50 CFDs your position will be worth $1000 ($20 x 50), but you will only need to deposit margin of $100 ($2 x 50).

If the stock price rises and you sell at $25, your profit is $250 ($5 x 50). If the stock price falls and you sell at $15, your loss will be $250 ($5 x 50).

If you had instead bought the shares with the $100, you would have only been able to buy 5 shares. So, your profit or loss would have been $25 ($5 x 5).

Long and short CFD positions

Using a long or short option involves betting on a Contract for Difference moving

up or down in value. The difference between your long and short option represents your post-trade profit or loss.

When you open a "long position", you purchase an asset in the hope that its value will increase. Its name comes from the phrase "long term", the logic being that markets tend to rise gradually over a much longer period of time than they fall. Thus, opening a long position means buying.

A "Short position", on the other hand, is when you sell an asset in the hope that it will decrease in value.  This name derives from the phrase "short term" since markets typically fall sharply in a short space of time. Therefore, opening a short position means selling.

What are the associated costs of CFDs trading?

  • Spread: when trading CFDs, you must pay the spread (the difference between the buy price and the sell price). When you enter the market, the price you pay is known as the buy price. The sell price is what you receive on exiting. The smaller the spread, the less the price needs to move in your favour before you start making a profit (or loss in the event that the price moves against you). At Libertex, we make sure we consistently offer our customers competitive spreads.
  • Maintenance fees: at the end of each trading day, any open position in your account may be subject to a charge known as a "maintenance fee". Maintenance fees may be positive or negative depending on the direction of your position and the applicable maintenance rate.
  • Commission: you must also pay a separate commission fee when exchanging CFDs.

Benefits and risks

Benefits and risks

CFDs offer a flexible alternative to traditional investment and therefore represent an attractive instrument for a wide variety of traders. It is possible for beginners to trade CFDs successfully, but they must first do thorough research into the benefits and risks involved before using real money.

With proper preparation, traders can take full advantage of many of the positive aspects of CFDs, while simultaneously minimising the potential drawbacks.

Advantages of CFDs

We have compiled a list of the main advantages typically associated with CFD trading. Investors who use a wide variety of trading strategies will find some or all of these techniques are compatible with their methods. Once you have read our list, it will become clear why so many different types of traders use CFDs to speculate on the financial markets.

  • Ability to achieve potential profits in both up and down trending markets

A clear advantage of CFD trading is that traders do not limit themselves to positions in a single type of economic environment (e.g. buy positions in an

up-trending market). The ability to trade in both bull and bear markets adds flexibility to your trading strategy and allows you to forecast price movements that match underlying fundamentals (which can fluctuate both up and down).

  • Hedging positions with CFDs

CFDs can be used to hedge positions in other asset classes. For example, if you have a long position in a stock that is losing value, you can open a short position in a CFD on the same stock. Profits on the short position will then offset the losses on the long position. When the stock price stabilizes you can close the short position.

  • Flexible contract sizes

Many CFD traders have a variety of trade sizes at their disposal which they can use for various trading styles or investment account types. As a general rule, beginners want to limit themselves to smaller-sized lots until they have developed a successful trading strategy that generates sustained, long-term profits. Experienced investors may opt to risk more money to avoid feeling limited in their trading structure.

  • Trading margin

Margin trades are usually allowed for CFDs, which means that traders are only required to deposit a portion of the actual transaction size for each trade. This allows you to increase your buying power in the market to generate potential higher returns.

  • One account, multiple asset classes

CFDs allow you to trade forex, shares, indices, commodities, and cryptocurrencies with one account and one platform. If you trade the underlying assets you will need to open a different account for each asset class.

Risks involved in CFD trading

Like anything in life, CFD trading is not without its risks. Most of these potential negative effects can be reduced with proper research and by following a structured trading plan. But you must remember that there is no way to completely eliminate all risk. The best we can hope for is to minimise the possible negative effects. With this in mind, we recommend you take note of the following potential pitfalls:

  • Over-leveraging of positions

Far and away the biggest mistake that new traders can make is risking too much on a given position. One of the reasons "over-leveraging" occurs so frequently with inexperienced traders is that many of them look at CFD trading as a new career and a path to wealth. When given the chance to place leveraged trades (with the potential for improved earnings), many new traders abuse this opportunity and incur significant losses (or even completely wipe out their trading accounts) in the process.

Now, this shouldn't be cause for discouragement since this error is easily avoided.

All you need is an appropriate risk management strategy: use stop orders to limit the size of your losses and risk only a manageable proportion of your trading capital.

Traders must remember to be prudent at all times as they aim to create a base of CFDs that generate steady, long-term profits, instead of trying to hit a perfect "hole-in-one" at every opportunity.

  • CFDs confer no voting rights

Unlike shares, a CFD does not give you the right to vote at a company’s annual general meeting. This is a minor drawback as a shareholder’s vote is only meaningful if they have a very large position.

CFD Instruments

The trading instruments available to trade as CFDs vary from broker to broker. Liquid instruments are better suited to CFD trading, so most brokers stick to large cap stocks and popular forex pairs.

Libertex offers CFDs on 50 stocks listed around the world, over 40 cryptocurrencies, 45 currency pairs as well as several stock indexes, metals, energy products, soft commodities, and ETFs.

Choosing CFD Instruments to trade

It can be tempting to try to trade too many types of instruments. Rather, you should stick to a few types of instruments that you understand and find interesting. Most of the best traders specialize on one or two markets.

The timeframe you trade on, the hours you trade, and your style of trading may also be better suited to some instruments. If you trade on very short time frames, cryptocurrencies and very liquid currency pairs may be for you.

Commodities and indices are well suited to medium term timeframes with a holding period of one to five days. Shares and exotic currency pairs are suited to

longer timeframes, unless there is a lot of short-term volatility. When trading CFDs on shares, day traders stick to the companies that are in the news. However, CFDs on shares can also be traded over the medium to long term.

Commodities and emerging market currencies are also well suited to long term trend following due to their cyclical nature.

How to find CFD trading ideas

There are lots of ways to generate trading ideas. You can analyse an instrument’s fundamentals, you can trade based on the news, or you can use chart patterns and indicators. Most traders develop their own strategy based on a combination of methods.

Broadly speaking there are two approaches to trading. Either you trade in the direction of the trend and momentum if you believe a price will continue moving in that direction. Alternately, you can trade against the direction the price is moving if you believe the price will revert to the mean or a major reversal will occur.

Trading with trend and momentum:

For a trade in the direction of the trend to be profitable, the price needs to continue moving in the same direction. The probability of that is higher when one or more of the following happen:

  • volume is high,
  • major technical levels have been breached,
  • news flow continues to support the direction of the price.

The same factors apply to long and short positions. To find good trading ideas you need to look for instruments where these factors are present.

Trading against the trend:

When prices move too far in one direction, they will often reverse course. This can occur on any time frame, and the price will often move back to the middle of the trading range, and possibly to the opposite side of the trading range.

On shorter timeframes, prices revert to the mean when:

  • they reach a support or resistance level,
  • the price becomes overbought or oversold,
  • or, volume falls, signalling there are few remaining buyers or sellers.

On longer timeframes, prices reverse direction when:

  • the valuation becomes too low or too high,
  • an economic cycle turns,
  • or, the fundamentals behind the instrument change.

  Account size

Each broker has their own minimum account size and minimum trade size. You will need to check that the available options suit your budget.
