Ethereum CFD trading: contract sizes, 2:1 margin, sizing and costs

An Ethereum CFD is a contract with a broker that pays out the change in the price of ether (ETH) between opening and closing the trade, without you ever owning the coin. Retail clients in the EU can use leverage of up to 2:1, so opening a position requires margin of half its value, and every dollar the price moves is multiplied by the number of ETH the contract represents. Getting the size right depends on reading the broker's contract specification, sizing from your stop rather than your margin, and counting the costs that run while you hold.

This guide is about the mechanics of trading ether through CFDs. For what Ethereum is (smart contracts, proof of stake, gas fees), see our guide to Ethereum and altcoins. For the wider choice between a CFD and buying the coin, see crypto CFDs vs buying crypto.

What you are trading

A CFD on ether tracks the ETH price, usually quoted against the US dollar (ETH/USD), sometimes against the euro or another currency. When you buy, you gain if the price rises and lose if it falls; when you sell (go short), the reverse. Our guide to what a CFD is covers the product in general.

What you do not get matters as much as what you do:

• No coins. You cannot withdraw ether to a wallet, send it, or use it on the Ethereum network.
• No staking rewards. Ether held directly can be staked to earn rewards for helping secure the network. A CFD position earns nothing of the kind; it costs financing instead.
• A contract with your broker. Your counterparty is the broker, so the safety of your position depends on the broker's regulation, client money rules and solvency. Our guide to checking a broker licence explains how to confirm who you are dealing with.

In exchange you get the ability to go short as easily as long, use limited leverage, and trade inside the same account and platform you might use for currencies or indices.

Who can trade ether CFDs

• EU retail clients can trade crypto CFDs with leverage capped at 2:1, alongside the other ESMA protections: a margin close-out when equity falls to 50% of required margin, negative balance protection, and a standardised risk warning. Our guide to ESMA leverage limits explains these rules.
• UK retail clients cannot trade crypto CFDs at all. The FCA banned the sale of crypto derivatives to retail consumers from January 2021.
• Elsewhere, rules vary widely, and some offshore brokers offer far higher leverage on crypto. Higher leverage does not change the price risk; it only shortens the distance to a forced close.

Contract sizes: read the specification

There is no standard lot size for crypto CFDs. Each broker sets its own, and the same platform can label very different exposures as "1 lot". Typical arrangements include:

• 1 lot = 1 ETH. A move of 1 dollar in the ETH price changes a 1-lot position's value by 1 dollar.
• 1 lot = 10 ETH. A 1-dollar move is worth 10 dollars per lot, and the minimum trade might be 0.01 lots, which is 0.1 ETH.
• 1 lot = 0.1 ETH, or positions specified directly in coins or in currency amounts.

Before trading, find the instrument's contract specification (in MetaTrader, right-click the symbol and open the specification) and note four things: the contract size, the minimum volume, the volume step, and how financing is charged. Our guide to lot sizes and position sizing explains lots in general; the contract size entry in the glossary defines the term.

A useful habit is to convert every position to "number of ETH" before thinking about anything else. Number of ETH times the price gives the position value, and number of ETH times a price move gives the profit or loss.

Margin at 2:1

With 2:1 leverage, the margin required is 50% of the position value.

• Position value = number of ETH times the ETH price.
• Margin = position value divided by 2.

Illustration: 0.5 ETH at 3,000 dollars is a position worth 1,500 dollars, needing 750 dollars of margin. The margin is a deposit, not a cost, but it does tie up a large share of a small account. The crypto margin calculator runs the numbers for any size and price, and our guide to leverage and margin explains the concepts.

Margin is not a measure of risk. A position with 750 dollars of margin can lose more than 750 dollars if the price moves far enough and you have more funds in the account. The amount you can lose is set by the size of the position and the distance to your exit.

Sizing an ether trade from the stop

Start from the price at which the trade idea is wrong, as our guide to crypto stop loss placement explains, then work out the size that limits the loss at that stop to a set share of the account.

Worked example 1: a dollar account, 1 lot = 1 ETH

Illustrative numbers only.

• Account: 5,000 dollars. Risk per trade: 1%, so 50 dollars.
• Entry: buy at 3,000 dollars. The daily ATR is 120 dollars (4% of price), and the stop is placed 1.5 times ATR below the entry, 180 dollars away, at 2,820 dollars.
• Size: 50 divided by 180 = 0.277 ETH. Rounding down to the volume step of 0.01 gives 0.27 ETH, which is 0.27 lots here.
• Loss if the stop fills at 2,820: 0.27 times 180 = 48.60 dollars, before costs.
• Position value: 0.27 times 3,000 = 810 dollars. Margin at 2:1 = 405 dollars.

The margin used is about 8% of the account, while the risk is about 1%. Those are two different numbers answering two different questions, and beginners often confuse them.

Worked example 2: the same trade where 1 lot = 10 ETH

At a broker where one lot is 10 ETH, with a minimum of 0.01 lots and a step of 0.01 lots, each step is 0.1 ETH.

• The ideal size is still 0.277 ETH.
• The nearest size that does not exceed it is 0.02 lots, which is 0.2 ETH.
• Loss at the stop: 0.2 times 180 = 36 dollars, or 0.72% of the account.

Rounding up to 0.03 lots (0.3 ETH) would risk 54 dollars, more than planned. Coarse volume steps mean that on a small account the actual risk can be noticeably lower than the target; that is the safe side to err on. If the step is so coarse that even the minimum trade exceeds your risk limit, the trade is too big for the account.

Worked example 3: a euro account trading ETH/USD

Now the account is in euros: 5,000 euros, risk 1% = 50 euros. ETH/USD is quoted in dollars, so the risk has to be converted. Assume, for illustration, that EUR/USD is 1.10.

• Risk in dollars: 50 times 1.10 = 55 dollars.
• Size with the same 180-dollar stop: 55 divided by 180 = 0.305 ETH, rounded down to 0.30 ETH.
• Loss at the stop: 0.30 times 180 = 54 dollars, which is 54 divided by 1.10 = about 49.09 euros.
• Margin: 0.30 times 3,000 divided by 2 = 450 dollars, about 409 euros.

Two extra points follow. First, the broker converts the dollar result into euros, often with a conversion fee, which our guide to currency conversion and account base currency covers. Second, your euro result depends on EUR/USD as well as on ether. The crypto position size calculator handles the conversion for you.

What it costs

Spread

The spread is the gap between the buy and sell price. On ether it is usually wider than on major currency pairs and widens further when the underlying market is thin or moving fast. As an illustration, a spread of 3 dollars on a 0.27 ETH position costs 0.27 times 3 = 0.81 dollars to cross. Small on a single trade, but it is paid on every trade and becomes significant for frequent, short-term trading. Some brokers charge a commission instead of, or as well as, a wider spread. Our guide to how to compare trading costs shows how to build an all-in figure.

Overnight financing

Holding a CFD past the broker's daily cut-off incurs a financing charge, calculated on the full position value, not on your margin. Crypto CFDs often charge both long and short positions, and the charge usually applies every calendar day, weekends included. Our guide to crypto CFD overnight fees explains the methods brokers use.

Illustration: if the broker charged 0.05% of position value per day, the 810-dollar position from example 1 would cost about 0.405 dollars a day, or roughly 12.15 dollars over 30 days. That is about a quarter of the 50-dollar risk budget, paid whether the trade wins or loses. For positions held for weeks or months, financing can become the largest single cost, which is why some traders prefer to buy the coin itself for long-term holding.

Currency conversion

If your account is not in dollars, profits, losses and financing on ETH/USD are converted into your account currency, sometimes with a mark-up. Over many trades this is a real cost; check the broker's stated conversion fee.

Margin close-out: how far can ether fall?

Under the ESMA rules, the broker must start closing positions when your account equity falls to 50% of the margin required for your open positions. How far the price can move before that happens depends on how much spare money is in the account.

• If the account held only the margin. In example 1, 405 dollars of margin. Close-out is reached when equity falls to 202.50 dollars, a loss of 202.50 dollars. On 0.27 ETH that is a fall of 750 dollars, or 25% of the entry price, before costs. At 2:1, a 25% adverse move is always the point where a margin-only account reaches close-out.
• With the rest of the 5,000-dollar account behind it. The spare equity absorbs losses first, and a single 0.27 ETH position could not lose enough to reach close-out even if ether went to zero. Here, the stop is what limits the loss, not the close-out.

Ether has made moves of 25% within short periods more than once, so a margin-only account can be closed out on ordinary crypto volatility. Our margin call and stop-out guide explains margin levels, and crypto volatility and risk works through a close-out example on bitcoin.

What moves the ether price

ETH is driven by many of the same forces as the rest of crypto: overall risk appetite, liquidity, leverage in the market and the bitcoin price. It also has its own drivers.

• Network upgrades. The Merge, which switched Ethereum from proof of work to proof of stake, took place in September 2022. Major upgrades attract attention before and after they happen, and any technical problem around them is a source of risk.
• Activity on the network. Demand for block space, use of decentralised finance and the growth of layer 2 networks all feed into narratives about ether's value. The planned guides to layer 2 scaling and gas fees explain these.
• Staking. A large share of ether is staked. Changes to staking, and to how staking is treated by regulators and fund products, can affect sentiment. The planned guide to ether staking covers the mechanics.
• Fund products. Spot ether exchange-traded funds began trading in the United States in July 2024, adding another channel of demand and supply.
• The ETH/BTC relationship. Ether often moves with bitcoin but not one-for-one, and it has frequently moved more than bitcoin in percentage terms in both directions.

None of these produce reliable predictions. Their practical relevance to a CFD trader is that they can make volatility jump suddenly, which affects stop distance, spreads and gap risk.

Hours, weekends and gaps

Ether trades on exchanges around the clock. CFD providers often quote it through the weekend too, but schedules differ: some pause for maintenance, some widen spreads sharply in quiet hours. If the price feed pauses and the underlying market moves, your position reopens at the new price and a stop can be filled beyond its level. Our guide to gap risk and weekend risk explains how that works. Check your broker's trading hours for the ETH CFD specifically, not just for crypto in general.

Going short

Selling an ether CFD is as simple as buying one: you profit if the price falls and lose if it rises. The loss on a short is not capped by a price of zero, because the price can keep rising. Shorts are often charged overnight financing as well, so a short held for weeks pays a running cost while waiting. Use the same stop-based sizing as for a long position.

Common mistakes

• Assuming "1 lot" means the same thing everywhere. Moving between brokers, or between a demo and a live account with a different specification, can multiply the position size by ten without the number on screen changing.
• Sizing from margin. "I'll use 1,000 dollars of margin" says nothing about how much you can lose. Size from the stop.
• Rounding up. If the ideal size falls between volume steps, take the smaller one.
• Forgetting the conversion. A euro or sterling account trading ETH/USD needs the risk converted to dollars before sizing.
• Ignoring financing on longer holds. A fee charged daily on the full position value can quietly consume the gains on a slow trend.
• Treating ether like a major currency pair. Stops sized for currencies sit inside ether's normal noise.
• Holding a near margin-only account. At 2:1, a 25% move closes a margin-only position, and ether can move that far.

Most retail CFD accounts lose money. Ether's volatility means that sizing mistakes are punished quickly, so the arithmetic above deserves more attention than the entry signal.

Frequently asked questions

What is the leverage on an Ethereum CFD?

For retail clients in the EU, the maximum is 2:1, so the margin required is 50% of the position value. Professional clients and clients of firms outside the EU may be offered more. In the UK, retail clients cannot trade crypto CFDs.

How much is one lot of ETH in a CFD?

It depends on the broker. One lot is commonly 1 ETH, but some brokers use 10 ETH, 0.1 ETH or another figure, and some let you specify the position in coins. Check the contract specification for the contract size, minimum volume and volume step before you trade.

How do I calculate the size of an ether CFD position?

Decide how much you are prepared to lose if your stop is hit, divide it by the distance from entry to stop in dollars, and round down to the broker's volume step. If your account is not in dollars, convert the risk into dollars first. Then check that the margin is acceptable.

Do I get staking rewards on an ether CFD?

No. A CFD gives you exposure to the ETH price only. You do not hold ether, so you cannot stake it, and you will usually pay an overnight financing charge rather than receive anything for holding the position.

Are ether CFDs charged at weekends?

Usually, yes. Most brokers charge crypto CFD financing for every calendar day the position is held, including weekends, and some charge both long and short positions. The exact method is in the broker's contract specification or fee schedule.

How far can ether fall before my CFD is closed out?

Under ESMA rules the broker closes positions when equity falls to 50% of required margin. If the account holds only the margin for one ether position at 2:1, that point is a 25% adverse move before costs. Extra funds in the account push it further away, but they are also at risk.
