Risk warning: CFDs are complex instruments. The majority of retail investor accounts lose money when trading CFDs. You should consider whether you can afford to take the high risk of losing your money.

Spread and commission are easy to compare — brokers advertise them. The swap fee is different. It is set per instrument, quoted in inconsistent units, and buried in the contract specifications rather than the marketing page. For any trader who holds positions overnight, the swap can quietly become the largest cost of trading. This checklist walks you through exactly where to look in a broker's terms, and the traps to watch for, before you fund an account.

This is a focused companion to our broader hidden fees checklist. If you want the numbers side-by-side, use the swap fee comparison and the swap calculator; if you want the concept first, read understanding swaps and overnight fees.

Your hidden-swap-fee checklist

Tick each item as you verify it in the broker's terms and platform. All 6 should be checked before you hold any position overnight.

0 of 6 items checked

✓ Open the contract specifications for the exact instruments you will trade

Swap rates are set per instrument, not per account. The headline swap on EUR/USD tells you nothing about the swap on GBP/JPY, gold, or an index CFD. Read the swap for every symbol you actually intend to hold overnight — exotic pairs and commodities are usually far more expensive than majors.

Where to look: In MT4/MT5, right-click the symbol → Specification, and read Swap Long and Swap Short. On web or app platforms, look for "Instrument details", "Trading conditions", or "Symbol information". Reputable brokers also publish a full swap table on their website.

✓ Confirm whether swaps are quoted in points, account currency, or percent

A swap value of "-7.2" is meaningless until you know the unit. Brokers use different conventions: points (pips), a fixed amount of account currency per lot, or an annualised percentage. Two brokers can look similar and cost very differently once you convert to the same unit.

What to confirm in the terms: the unit used, the calculation type ("in points" vs "in money"), and the contract size the figure is based on. Only then can you translate the swap into a real cost per night per lot and compare brokers fairly.

✓ Find the triple-swap day and the daily rollover time

To cover the weekend, brokers charge three days of swap on one weekday — usually Wednesday for forex, though it can differ for other instruments. The charge is applied at a fixed rollover time (commonly 22:00 or 00:00 server time). Holding a position through the triple-swap day roughly triples the overnight cost for that night.

What to confirm in the terms: which weekday carries the triple charge for each instrument class, the exact rollover time, and the server time zone. If you day-trade and always close before rollover, swaps may not apply to you at all — but confirm the cut-off.

✓ Read the swap-free / Islamic account clause for administration fees

A "swap-free" or Islamic account removes the interest-based swap — but many brokers replace it with a fixed administration or holding fee, often after a grace period of a few nights, or on specific instruments such as exotic pairs, metals and commodities. The "zero swap" headline can still carry a nightly charge that only appears in the terms.

What to confirm in the terms: whether an administration fee replaces the swap, when it starts (immediately or after N nights), which instruments it applies to, and how it is calculated. Compare that fee against the ordinary swap you would have paid — sometimes the standard account is cheaper.

✓ Check for a broker markup on top of the interbank rate

In principle the swap reflects the interbank interest-rate differential between the two currencies in a pair. In practice, brokers may add a markup. A common tell: on a pair where the two currencies have a small rate differential, both swap long and swap short are clearly negative, or the gap between them is much wider than the differential would justify.

What to confirm in the terms: whether the trading-conditions page states a markup or the formula used to derive swaps. If it is not disclosed, ask support directly: "Is a markup applied to your swap rates, and if so how much?" A broker that cannot answer plainly is a flag.

✓ Test one instrument on a demo statement

The terms tell you what should happen; the statement tells you what does. Open a small demo position on the instrument you plan to hold, leave it open past the rollover time, then read the account statement line that records the swap. This is the single most reliable way to confirm the real overnight cost matches the disclosed rate.

How to verify: in MT4/MT5, open the Account History tab after rollover and find the "swap" column on the open position. Multiply by the number of nights you expect to hold, and remember the triple-swap day, to estimate your true monthly overnight cost.

The MiFID II disclosure rule for overnight costs

Under MiFID II, EU-regulated brokers must provide a full costs and charges disclosure before you open an account, and this includes overnight financing (swap) costs. "Disclosed" does not mean "prominent", though — the figures often live in the contract specifications rather than the marketing pages. If a broker will not show you the swap schedule until after you deposit, that is a regulatory concern you can raise with CySEC (cysec.gov.cy) or your national regulator.

Rule of thumb: if you hold positions for days or weeks, estimate your swap cost before you compare spreads. On exotic pairs and some CFDs, a few nights of swap can outweigh the entire spread saving that made a broker look cheap.

Frequently asked questions

Where in a broker's terms are swap fees disclosed?

Usually in two places: the per-instrument contract specifications inside the trading platform (right-click a symbol in MT4/MT5 and open Specification to see Swap Long and Swap Short), and the broker's trading-conditions or fee-schedule page on their website. Under MiFID II, EU-regulated brokers must make this cost information available before you open an account.

Why are swap long and swap short different?

A swap reflects the interest-rate differential between the two currencies in a pair. Depending on which currency you are effectively borrowing and which you hold, one direction may earn a small credit while the other is charged. If both directions are negative, or the gap is far wider than the rate differential suggests, the broker is likely applying a markup.

Does a swap-free account mean there are no overnight costs?

Not necessarily. Many swap-free or Islamic accounts remove the interest-based swap but replace it with a fixed administration or holding fee, often after a grace period or on specific instruments such as exotic pairs and commodities. Read the swap-free clause in the terms to see whether an administration fee applies and how it is calculated.

What is the triple-swap day?

To account for the weekend, brokers typically charge three days of swap on a single weekday — usually Wednesday for forex. Holding through that day means paying roughly three times the normal nightly swap. The exact day and the daily rollover time are stated in the broker's terms.
