Choosing Assets to Trade with CFDs

CFDs let a trader take exposure to the price movement of an underlying market without owning that asset. That broad access is useful, but it creates a selection problem: a platform may offer currency pairs, stock indices, individual shares, commodities and other markets that behave very differently even though the trade ticket looks similar.

The old instinct is to search for the market that moves the most. That is incomplete. Leverage can magnify a relatively small price move, but it does not remove the effects of liquidity, spread, commission, financing, market closures, slippage or event risk. A market that looks exciting on a chart can be a poor CFD candidate if too much of its normal movement is consumed by trading costs or if its price regularly jumps through the level at which you intended to exit.

A better way to choose is to ask whether the market fits the way you intend to trade. The relevant comparison is not simply “Which asset is most volatile?” It is whether the market offers enough usable movement, at acceptable cost and risk, during the hours you can trade, with position sizes that let you control losses.

Choosing the market matters more than choosing the maximum leverage

Leverage is one reason traders are attracted to CFDs, but maximum leverage should not determine the asset. The practical question is how much exposure a position creates relative to the amount you are prepared to lose if the trade is wrong. A low-volatility market can still create a large account-level loss when the position is oversized, and a more volatile market can sometimes be traded at a smaller size so that the planned loss is similar.

Retail leverage limits also differ by underlying asset in regulated CFD markets. Australia’s ASIC framework, for example, caps retail CFD leverage at 30:1 for major currency pairs, 20:1 for minor currency pairs, gold and major stock indices, 10:1 for other commodities and minor indices, 5:1 for shares and other assets, and 2:1 for crypto-assets. ^[1] The UK’s FCA rules likewise restrict retail CFD leverage to a range of 30:1 to 2:1 and pair those limits with margin close-out and negative-balance protections. ^[2] Those rules are jurisdiction-specific, but they illustrate an important point: regulators themselves treat the risk characteristics of underlying assets as materially different.

That is why the leverage involved in CFD trading should be considered after the market’s normal behavior, not before it. The margin required to open a position is not the same thing as the economic risk of that position. If a broker requires $500 of margin for one trade and $1,000 for another, the first trade is not automatically safer, cheaper or better. What matters is the notional exposure, the likely adverse movement before the trade thesis fails, and how reliably the position can be closed around that level.

Traders who are still learning CFD trading are usually better served by choosing markets whose mechanics they can understand and observe consistently. Maximum available leverage is best treated as a ceiling imposed by the product and the regulator, not as a suggested position size.

Compare trading costs with the movement you are trying to capture

The old article was right to focus heavily on trading costs, but “commission-free” is too narrow a way to think about them. CFD costs can include the bid-ask spread, a dealing commission, overnight funding, currency conversion, market-data charges and, for some order types, a guaranteed-stop premium. The exact mix depends on the provider and the market. IG’s current cost schedule, for example, separates spreads, commissions, overnight funding, guaranteed-stop charges, currency conversion and market-data costs, and notes that spreads can change with market conditions and liquidity. ^[3]

For asset selection, the useful comparison is cost relative to the movement your strategy is trying to capture. Suppose one market costs the equivalent of two points to enter and exit and your typical successful trade captures ten points before other costs. The dealing cost consumes 20% of that gross move. If another market costs four points but your comparable strategy typically captures fifty, the larger quoted spread may actually represent a smaller burden. The raw spread alone therefore does not tell you which market is cheaper for your approach.

This is the useful core of the old “spread to range” idea, but it needs one refinement: historical range is not expected profit. A market can have a wide average daily range and still be difficult to trade because much of that movement occurs in sudden jumps, reversals or news-driven bursts. It can also have an attractive headline spread during liquid hours and much worse pricing when you actually trade. The relevant measure is the all-in cost against the movement your tested entry and exit rules have historically been able to capture.

Time horizon changes the calculation further. A trader opening and closing positions within the same session may care primarily about spread, commission and slippage. A position held for several nights can accumulate financing charges, making a market that is efficient for intraday trading less attractive for a longer holding period. If the strategy regularly holds positions overnight, financing belongs in the expected trade economics from the start rather than being treated as an incidental fee after the trade is open.

The comparison with ETFs is useful when the objective is broad market exposure over a longer period. A CFD and an ETF can reference similar market performance, but their cost structures and ownership rights are different. For a short-term leveraged trade, a CFD may fit the objective; for an unleveraged long-term allocation, repeatedly paying CFD financing can make the derivative an unnecessarily expensive way to express the same broad view.

Liquidity and execution quality shape the real trade

Liquidity matters because the chart is only part of the trade. A highly liquid underlying market generally supports tighter pricing and more reliable execution, especially at ordinary trade sizes. In thinner markets, quoted spreads can be wider, the available price can move more quickly when an order arrives, and slippage can become a larger part of the result.

CFDs are over-the-counter contracts with the provider, so a trader is not placing the CFD itself into the central order book of the underlying exchange. Even so, the quality and liquidity of the reference market matter because the provider uses that market, directly or indirectly, to price and hedge the CFD. A thinly traded share, minor commodity contract or exotic currency can therefore behave very differently from a major index or heavily traded currency pair even if both are accessible from the same CFD account.

Liquidity is also time-dependent. A market can be easy to trade during its main session and noticeably worse when the underlying exchange is quiet or closed. Around major economic releases, company announcements or geopolitical events, spreads can widen just as volatility rises. Traders sometimes interpret increased volatility as better opportunity without accounting for the fact that execution conditions may deteriorate at the same time.

This is why “predictability” should not be treated as a permanent quality of an asset. No CFD market is reliably predictable in the everyday sense of the word. What can be tested is whether a specific set of trading rules has behaved consistently enough in a particular market and session to justify further use. A market that trends cleanly for several weeks can become choppy; a strategy that works during one volatility regime can weaken in another. Asset selection should therefore be revisited with data rather than based on a permanent label such as “well behaved.”

Trading hours, gaps and event risk

Market hours affect both opportunity and risk. Major forex markets trade through the working week across global sessions, while individual shares remain closely tied to the trading hours of their underlying exchange even when a broker offers some extended-hours dealing. Index and commodity CFDs may quote for much longer than the main cash session because providers can reference related futures or other markets, but the quality of those quotes and the spread can change outside the most liquid hours.

A long trading window is valuable only if it matches your schedule and strategy. Someone who can trade only during the European morning may get little benefit from following a market whose most liquid period occurs during U.S. hours. Conversely, a market with a well-defined active session can be easier to study because the trader sees a consistent mix of volume, news and price behavior each day.

Gaps deserve separate attention. When the underlying market is closed, information continues to arrive. A share can reopen sharply higher or lower after earnings, a profit warning, a takeover announcement or sector news. A stop order does not guarantee an execution at the stop price when the next available tradable price is materially different. Some providers offer guaranteed stops on eligible markets for an additional cost, but availability and terms vary.

Individual shares are especially exposed to company-specific event risk because one announcement can reprice the security before normal liquidity returns. Broad stock indices spread company-specific risk across many constituents, although they can still gap after macroeconomic or geopolitical developments. Commodities can react abruptly to inventory reports, weather, supply disruptions or policy decisions, while currencies can move sharply around central-bank decisions and major economic data. The right asset is partly the one whose event calendar you are prepared to monitor.

How the main CFD asset classes differ

Forex and currency CFDs

Major currency pairs are often attractive to active CFD traders because they combine long trading hours with deep underlying markets. The price movement of a major currency pair may look modest in percentage terms compared with an individual stock, but leverage means there is no need to search for an exotic pair merely to create account-level movement. More volatile or less liquid pairs often come with wider spreads and different overnight financing dynamics.

Currency trading also has a distinct information structure. Interest-rate expectations, inflation, employment data, central-bank communication and broad risk sentiment can all affect exchange rates. Traders who follow macroeconomic releases closely may find that structure useful, while someone whose edge is based on company-specific analysis may be better suited to shares.

The strongest reason to prefer a major pair is therefore not that it is automatically more profitable. It is that liquid pairs usually provide a large amount of observable price history, frequent trading opportunities and a relatively clean way to compare execution and strategy performance across sessions. If the strategy depends on holding positions overnight, the interest-rate differential embedded in forex funding also needs to be part of the test.

Stock index CFDs

Stock index CFDs provide exposure to the movement of a basket of shares rather than one company. That reduces single-company event risk and makes the trade more dependent on market-wide factors such as interest rates, earnings expectations, economic growth and investor risk appetite. For traders who want to express a view on a national or sector market rather than identify a particular company, an index is often the more direct instrument.

Indices can also be operationally simpler than scanning hundreds of shares. A trader can become familiar with the behavior of one or two major indices, the hours when they are most liquid, and the economic releases that typically matter. That does not make the index safer in a leveraged position. A sharp market-wide move can still produce a large loss, particularly when the position size was chosen from the margin requirement rather than from the planned stop distance.

The old article argued that indices are generally preferable to shares because they often avoid share commissions and can trade for longer hours. That conclusion is too broad. Pricing models vary by CFD brokers, and some share products can be competitively priced for a strategy that benefits from company-specific movement. The more defensible distinction is that indices concentrate market risk while shares add company-specific risk, and the trader should choose whichever source of movement matches the strategy being tested.

Share CFDs

Share CFDs are useful when the trading idea is specifically about a company. Earnings, guidance, product announcements, mergers, litigation, regulatory decisions and analyst revisions can all create movement that a broad index may dilute. The same concentration is also the principal risk: the position can be repriced quickly by information that affects only that company.

Cost structures for shares deserve close inspection. Depending on the provider and jurisdiction, share CFDs may carry a separate commission, minimum dealing charge, exchange-data fee, currency conversion cost or stock-borrow charge for a short position. The headline spread on the screen is therefore not always the full round-trip cost. Thinly traded shares can also have wider underlying spreads and poorer execution than large, heavily traded companies.

Market closure risk matters more when a strategy holds a share CFD through earnings or another known catalyst. A tight stop does not eliminate the possibility of a much worse fill after a gap. That does not mean shares should be avoided; it means the position size has to reflect discontinuous price risk as well as the normal intraday range. For some strategies, the event risk is the reason to trade the share in the first place. For others, it is an unnecessary source of uncertainty.

Commodity CFDs

Commodity CFDs cover markets with very different economic drivers. Gold can trade as a monetary and risk-sensitive asset, crude oil responds to supply, demand, inventories and geopolitics, and agricultural markets can be heavily affected by weather and seasonal conditions. Treating “commodities” as one behavioral category is therefore not very useful.

Many commodity CFD prices are derived from futures markets. That introduces features that do not exist in the same form for an individual share, including contract expiries, the shape of the futures curve and the provider’s method for creating a continuous cash price. A trader should understand whether the CFD is a cash-style product with overnight funding, a forward or futures-style product with financing reflected differently in the price, and what happens as the reference contract approaches expiry.

Commodity volatility can be appealing, but larger movement is not free. Fast markets can produce wider spreads and slippage, and some commodities trade with thinner liquidity outside their most active hours. A strategy should therefore be tested on the exact product specification and session that will be traded, not on a generic long-term chart of the commodity.

Other markets and crypto-linked CFDs

Some providers offer CFDs referencing bonds, interest rates, sectors, options-like products or crypto-assets. Availability depends on jurisdiction, and a market offered to professional clients in one country may be restricted or unavailable to retail clients in another. The fact that a platform lists a market should never substitute for checking the local regulatory status and the provider’s product documentation.

Less familiar products can also introduce mechanics that are easy to miss. A rate or bond CFD may respond strongly to changes in yield expectations even though the quoted price appears less volatile than a stock. Crypto-linked derivatives can move continuously and sharply, but retail leverage may be heavily restricted where such products are permitted. A trader gains little by adding another asset class unless its behavior and costs are understood well enough to test it on the same basis as the existing shortlist.

Match the asset to your trading process

The best CFD market is strategy-dependent. A very short-term strategy needs enough liquidity and movement during the exact minutes or hours in which it trades to overcome spread, commission and slippage. A swing strategy that holds for several days is less sensitive to a one-point difference in entry spread but much more sensitive to overnight financing, weekend gaps and event risk. A news strategy may deliberately seek the volatility that another trader avoids.

Trading schedule matters just as much. If a trader has two reliable hours each day, the sensible universe is the set of markets that are liquid and active during those hours, not every instrument offered by the broker. Focusing on a small number of markets also makes it easier to learn their session structure, recurring economic events and normal response to volatility.

Familiarity should not be confused with intuition. Knowing that an index “usually bounces” at a certain time or that a currency “likes to trend” is not a trading edge until the idea has been defined and tested. A useful market is one for which the trader can describe the entry, exit, stop, position-sizing and no-trade conditions in advance and then evaluate the results after all costs.

Correlations also matter when more than one CFD is traded. Two positions can look like separate ideas while expressing almost the same underlying risk. Long positions in two closely related stock indices, for example, may both depend on the same broad equity-market move. Several dollar currency trades can create a large combined exposure to one macroeconomic theme. Choosing assets therefore includes understanding how positions interact at the portfolio level, not merely deciding whether each trade looks attractive by itself.

Build a small, testable market shortlist

A practical selection process starts with product specifications rather than chart excitement. For each candidate market, record the normal spread during the hours you intend to trade, any commission or minimum charge, the overnight funding method, margin requirement, contract size, trading hours and the rules for stops. If the account currency differs from the instrument currency, include conversion charges as well.

The next step is observation under realistic conditions. A demo account can show how the provider quotes the market, how spreads change around session boundaries and news, and whether the minimum trade size is compatible with the amount of money you are prepared to risk. Demo execution is not a perfect substitute for live trading, but it is a better place to reject an unsuitable market than after real money is exposed.

Strategy testing should then compare net results rather than gross chart movement. If two markets produce similar gross opportunities but one loses much more to spread, commission and financing, the difference belongs in the selection decision. Slippage assumptions should be realistic, especially for strategies that enter on breakouts or trade around news. A backtest that assumes every stop and entry is filled exactly at the requested price can make a difficult market look much cleaner than it will be in practice.

It is also useful to normalize trade risk before comparing performance. A strategy tested with a fixed number of contracts can make a volatile market appear more profitable simply because more money was at risk. Comparing candidates at a consistent percentage of account risk, using a stop distance appropriate to each market, gives a more meaningful picture of how efficiently the strategy uses risk.

A trader does not need a large watchlist to benefit from the range of markets available through CFDs. Breadth is valuable because it provides alternatives, not because every market should be traded. One or two well-tested markets may be enough for a narrowly defined strategy, while another approach may need several assets so it can trade only when specific conditions appear. The number should come from the process, not from a belief that more markets automatically create more opportunity.

What a good CFD market looks like for you

A good CFD market is one in which the trading opportunity survives contact with the product mechanics. There should be enough liquidity to enter and exit at reasonable cost, enough movement for the strategy to overcome those costs, trading hours that fit the trader’s schedule, and position sizes that allow losses to be contained without forcing stops inside ordinary market noise.

The asset class itself is only the starting point. Major currencies, indices, shares and commodities can all be sensible CFD underlyings when the strategy is built for their behavior and the costs are acceptable. The mistake is to rank them by maximum leverage, headline volatility or the smallest displayed spread without considering how the position will actually be traded.

Choosing assets is therefore less about finding the “best” CFD and more about eliminating markets that do not fit. Once costs, liquidity, event risk, financing, session structure and position sizing are considered together, the shortlist often becomes much smaller. That is useful: a smaller universe that has been tested properly is generally easier to manage than a platform full of instruments chosen because they happen to be moving today.
