ICE Futures Europe or CME: Where the Real Liquidity Is for a British Trader

You can trade a crude oil contract listed a short walk from Bishopsgate, cleared in London, supervised by the FCA. Or you can trade a crude oil contract listed in Chicago, on a venue you will never set foot in, whose busiest hour lands when you are thinking about dinner. Both appear in the same platform. Both are futures, both are leveraged, and the marketing around each one will tell you it is the obvious choice.

What ICE Futures Europe actually is

Start with the thing itself, because a lot of people trading from the UK have never looked. ICE Futures Europe is a London exchange. It belongs to Intercontinental Exchange, the American group that also owns the New York Stock Exchange, but the venue is a UK Recognised Investment Exchange, supervised here, with clearing at ICE Clear Europe.

Its product list is the result of two acquisitions. The energy complex came from the old International Petroleum Exchange, the open outcry oil market that ICE bought at the start of the 2000s and turned electronic. The financial complex, FTSE 100 index futures and options and the short term interest rate contracts, came across when ICE bought the London business of Liffe in the NYSE Euronext deal. So on one venue you have Brent crude, low sulphur gasoil, FTSE 100 futures, Three Month SONIA and Euribor. European gas and power mostly sit on a sister venue, ICE Endex.

None of that is a retail shop. It is a tier one venue with real institutional flow. The question is not whether ICE Futures Europe is serious. It is whether its contracts fit a person trading one to three lots from a spare room in Reading.

The contracts you would actually compare

Put the overlapping products side by side and the shape of the decision becomes clear.

Market	London, ICE Futures Europe	Chicago, CME Group
Equity index	FTSE 100 future, quoted at £10 per index point	E-mini S&P 500 (ES) at $50 per point, Micro E-mini S&P (MES) at $5, E-mini Nasdaq (NQ) at $20, Micro Nasdaq (MNQ) at $2
Crude oil	Brent (B), 1,000 barrels, one cent tick worth $10	WTI (CL), 1,000 barrels, one cent tick worth $10, plus Micro WTI (MCL) at 100 barrels and $1 a tick
Short term rates	Three Month SONIA, Three Month Euribor	SOFR futures, Fed Funds futures
Gold	Not the home market for it	COMEX gold (GC) at 100 ounces, Micro Gold (MGC) at 10 ounces

Two things jump out of that table. The first is that only one venue has a micro tier. The second is that the only genuine head to head is crude: Brent against WTI. Everything else is a comparison between a British index and an American one, which is a different decision altogether, because you are choosing an economy to trade and not just a venue.

Worth knowing: CME also lists a cash settled Brent contract, and ICE lists WTI too. The benchmarks cross venues. But the home of Brent price discovery is London and the home of WTI is Chicago and New York, and the front month order book reflects that.

Hours, and the life you actually have

This is where the local venue wins and nobody says it loudly enough.

The FTSE 100 future lives around the London cash session. From eight in the morning to half past four in the afternoon the underlying index is open, the order book is populated and the moves have a reason. If your day job starts at nine, or if you have children to collect at four, a London morning contract fits into your life in a way that an American index future never will.

CME equity index futures trade almost around the clock on Globex, but the session that matters, the regular trading hours that most strategies are built on, runs from half past eight in the morning to a quarter past three in the afternoon Chicago time. In London that is half past two in the afternoon until a quarter past nine at night in winter. The first hour, the one everybody wants, is your mid afternoon. The closing bell is your bedtime routine.

That trade off is the real one. If the only free window you have is seven to nine in the evening, the London venue is closed and CME is the only game available. If you are free in the morning and busy every evening, forcing yourself onto a Chicago clock is a slow way to burn out. Choose the venue that matches the hours you can honestly commit to, then judge everything else.

One more calendar detail: the United States and the United Kingdom do not move their clocks on the same weekend. For roughly three weeks in March and one week around the start of November the Chicago open lands an hour earlier on your wall clock than you expect. The cure is to run your platform on Chicago time, which we have written about separately.

Size, and what a tick really costs

Here is the part that decides it for most small accounts.

The FTSE 100 future is quoted at £10 per index point. Multiply the current index level by ten and you have the notional exposure of one contract, and at any level the FTSE has traded in recent years that is a five figure position in sterling. A move of thirty points against you, which is an ordinary morning wobble and not a crash, is three hundred pounds.

The Micro E-mini S&P is $5 per index point with a tick worth $1.25. The Micro Nasdaq is $2 per point with a tick worth fifty cents. Those are not small versions of a professional instrument as a marketing gesture. They are the reason a person with a two or three thousand pound account can trade a real exchange listed future, with a real stop, and size the position so that a bad day costs a tenth of the account instead of a third.

If you are running an account measured in tens of thousands and you trade one or two contracts a day, the granularity matters less and the FTSE contract is perfectly tradeable. If your account is small, or if your method needs to scale in and out in thirds, the absence of a micro on the local venue is close to decisive on its own.

Margin is the other half of the size question. Exchanges set initial and maintenance margins for each contract and publish them; brokers then apply their own intraday margin, which is usually far lower and can be changed at short notice, including in the middle of a volatile day. Never plan a position size from an intraday margin number. Plan it from what a normal adverse move costs you in pounds.

Where the depth really is

Now the uncomfortable part, told straight.

For equity index futures, the CME complex is in a category of its own. ES and its micro cousin form the deepest listed equity index market anywhere, and the Nasdaq pair is not far behind. The FTSE 100 future is a solid, functioning contract with genuine institutional users, and it is not in that conversation. That is not a criticism of ICE. It is arithmetic about where the world hedges equity risk.

For crude, the picture is completely different and much more favourable to London. Brent is the benchmark against which most physically traded crude in the world is priced, and the ICE Brent order book is a global market, not a local one. Anyone telling you that Brent is the thin option because it is European has not looked at a screen.

Do not take my word for either claim. Both exchanges publish their own numbers. CME puts daily and monthly figures on its volume and open interest pages, and ICE publishes equivalent market data reports on its own site. When you look, compare front month against front month, not the aggregate across all expiries, because the aggregate flatters contracts with long dated hedging activity and tells you nothing about whether you can get out of a three lot at half past two.

And remember what you actually need as a small trader. Headline volume is not the same as depth at the top of the book at the exact moment your stop fires. A contract that trades enormous size in a two hour window and goes quiet the rest of the day is a worse instrument for you than a smaller contract with a consistent order book, if your hours fall in the quiet part.

Commissions, data, and the costs nobody quotes you

The all in cost of a round turn has four parts: the exchange fee, the clearing fee, your broker's commission and the market data subscription. Brokers advertise the third one. The other three are where the surprises live.

Both exchanges publish fee schedules. Ask your broker for the complete round turn cost for the specific contract you intend to trade, in writing, including the exchange and clearing components, before you fund anything. If the answer arrives as a single marketing number with no breakdown, ask again.

Market data is the line item that quietly separates the two venues for a UK retail trader. CME non professional data is a familiar, modest monthly cost through most platforms. ICE sets its own data policy and the packages for its financial and energy products are priced with institutional users in mind. Check what your broker charges for ICE Futures Europe real time data before you build a plan around the FTSE contract, because the answer can be several times what you pay for the American exchanges.

Then there is currency, and this one runs in London's favour. Every CME contract settles in US dollars. Your profit, your loss and your margin all live in dollars, and at some point they get converted into sterling, with a spread, at whatever rate your broker uses. The FTSE contract is sterling from end to end. For a trader doing a handful of contracts a day, the conversion drag is not dramatic. For someone trading size, it is a real cost that never appears on a commission schedule.

Tax and record keeping, briefly

For a UK individual, gains on exchange traded futures normally fall under capital gains tax rather than income tax, which is a different treatment from the spread betting products sold to British retail clients. The annual exempt amount and the rates are published by HMRC and have been changed more than once in recent years: the exempt amount was cut to £3,000 from the 2024 to 2025 tax year and the main rates were raised in the autumn of 2024. Check the current year's figures on GOV.UK rather than trusting any number you read on a trading blog, including this one.

The practical difference between the venues here is paperwork. Sterling denominated contracts produce sterling gains. Dollar denominated contracts produce dollar gains that have to be converted into sterling for your return, and HMRC expects a consistent, defensible method for that conversion. Keep the statements, keep the rates you used, and keep them in the same place all year.

So which one

Honest answer, in two lines.

• ICE Futures Europe is the right call if your trading window is the London morning, if the FTSE is the index you actually follow, if you want sterling settlement and no currency conversion, and if your account is big enough that a £10 per point contract is a sensible unit of risk.

For most people reading this, it is CME, and the reason is the micro tier rather than any mystique about Chicago. But if you have been trading American indices at three in the morning your time because somebody told you that is where the action is, and your real free hours are between eight and eleven in the morning, the London venue deserves a look you have probably never given it.

Whichever you pick, the leverage is the same kind of leverage. Futures can lose you more than the money you deposited, a gap through a stop is not a theoretical event, and no indicator, ours included, changes that arithmetic. Size the position first, then argue about venues.
