The simplest answer is this:
Margin is the amount of account equity set aside to support an open leveraged position.
Free margin is the equity still available after the required margin for open positions has been deducted.
Margin level shows the relationship between your current equity and the margin being used, expressed as a percentage.
These three numbers tell you different things, but they work together.
If I had to explain them in one sentence, I would say:
Margin supports your trades, free margin shows how much room remains, and margin level shows how much breathing space your account has.
Understanding that relationship matters because Forex trading uses leverage.
The Bank for International Settlements reported that global foreign exchange turnover averaged about US$9.5 trillion per day in April 2025, up 27% from 2022. The US dollar was on one side of about 89% of global FX transactions.
Margin is not a trading fee.
It is money that your broker sets aside from your account equity while a leveraged position remains open.
Suppose you want to control a position worth US$10,000.
At 1:100 leverage, a simplified margin calculation would require about:
US$10,000 ÷ 100 = US$100
At 1:500 leverage, the same exposure would require about:
US$10,000 ÷ 500 = US$20
The position itself is still worth US$10,000.
Only the amount required to support that position has changed.
ZeonFX currently lists maximum leverage of 1:500 on major Forex pairs such as EUR/USD, GBP/USD and USD/JPY, although actual leverage depends on the instrument and account conditions.
This is why I never think of higher leverage as extra money.
It simply reduces the margin required for the same exposure.
You need to understand equity before free margin makes sense.
Your balance normally reflects the account value after closed transactions.
Your equity changes with the unrealised profit or loss of your open positions.
A simple way to think about it is:
Equity = Balance + Floating Profit or Loss
Imagine your account balance is US$5,000.
You have an open position currently showing a US$500 loss.
Your equity would be approximately:
US$5,000 minus US$500 = US$4,500
If that open trade instead had a US$300 unrealised profit, equity would be approximately US$5,300.
Equity therefore moves while your open positions move.
That is important because free margin and margin level are based on equity, not simply on your original deposit.
Free margin is the portion of your equity that is not currently being used as margin.
The basic calculation is:
Free Margin = Equity minus Used Margin
Consider this example.
Account balance: US$5,000
Floating loss: US$500
Equity: US$4,500
Used margin: US$1,000
Free margin:
US$4,500 minus US$1,000 = US$3,500
That US$3,500 is the remaining equity not currently tied up as required margin.
Free margin can help absorb further losses and may also be available to support additional positions.
That does not mean using all of it is a good idea.
When I look at an account, I prefer seeing spare margin rather than an account using nearly everything available. The reason is simple: markets do not move in perfectly straight lines.
Margin level tells you how much equity you have relative to the margin currently being used.
The formula is:
Margin Level = Equity ÷ Used Margin × 100
Using the previous example:
Equity: US$4,500
Used margin: US$1,000
Margin level:
4,500 ÷ 1,000 × 100 = 450%
So the account has a margin level of 450%.
Now imagine the open positions move further against you and equity falls to US$2,000.
Assuming used margin remains US$1,000:
2,000 ÷ 1,000 × 100 = 200%
The margin level has fallen from 450% to 200%.
If equity falls to US$1,200:
1,200 ÷ 1,000 × 100 = 120%
Nothing about the original account balance has to change for margin level to fall.
The unrealised loss alone can reduce equity and therefore reduce free margin and margin level.
Margin level is essentially an account pressure gauge.
A higher percentage generally means there is more equity relative to the margin currently supporting open positions.
A falling percentage means that buffer is getting smaller.
This becomes important when a trading account approaches its applicable margin call or stop out level.
ZeonFX's current terms state that traders are responsible for monitoring margin continuously. If equity reaches the applicable margin call level, a trader may need to deposit additional funds or reduce exposure. If equity falls to the applicable stop out level, some or all open positions may be closed automatically.
The exact level should be checked in the applicable account conditions rather than assumed.
A margin call is a warning that your account equity has fallen too close to the margin required to maintain your positions.
This can happen because:
Your open positions are losing value.
You are using too much of your available margin.
You have opened several leveraged positions at the same time.
Market volatility has caused equity to fall quickly.
A margin call does not mean the broker has charged you a new fee.
It means your account's available equity relative to its required margin has deteriorated.
A stop out is more serious.
It is the point at which the broker may begin automatically closing positions because the remaining account equity is no longer sufficient under the applicable margin rules.
ZeonFX states that positions may be closed automatically and without prior notice when the account reaches its applicable stop out level. It also warns that execution can occur at the best reasonably available price, which can be worse than the trigger level during fast markets.
That is one reason I would not wait until margin level is close to the platform threshold before thinking about risk.
Assume you start with:
Balance: US$5,000
Used margin: US$1,000
Floating profit or loss: US$0
Your equity is US$5,000.
Free margin is:
US$5,000 minus US$1,000 = US$4,000
Margin level is:
US$5,000 ÷ US$1,000 × 100 = 500%
Now the open trades move against you by US$2,000.
Balance remains US$5,000 because the trades have not been closed.
Equity becomes:
US$3,000
Free margin becomes:
US$2,000
Margin level becomes:
300%
The important lesson is that all three numbers are connected.
A floating loss lowers equity.
Lower equity reduces free margin.
Lower equity also reduces margin level.
That is how an account can move toward a margin call even though the original account balance still appears unchanged.
Leverage and margin are two sides of the same mechanism.
Higher available leverage generally means less initial margin is needed to control the same position.
But less required margin can also make it easier to take too much exposure.
The CFTC puts the risk clearly:
“This high degree of leverage amplifies both gains and losses.”
That is why the number I watch is not simply maximum leverage.
I look at how much exposure the account is actually carrying relative to its equity.
ZeonFX itself makes the same distinction in its current leverage education, noting that higher leverage reduces the margin needed for a position but does not automatically produce higher profit.
Calculating margin before entering a position is much better than discovering the requirement after the order is open.
ZeonFX currently provides a Trading Calculator that estimates required margin, pip value, potential profit or loss, swap charges and commission based on inputs such as instrument, leverage and position volume.
For me, the useful workflow is simple.
First decide the position size.
Then calculate the required margin.
Then look at how much free margin would remain.
Only after that should the leverage ratio enter the discussion.
A high margin level does not automatically mean a trade is safe.
It simply tells you how equity currently compares with used margin.
Market risk still depends on position size, volatility, price movement and how many correlated positions you hold.
For example, three different USD positions may technically be separate trades while all carrying exposure to the same underlying currency move.
Margin level cannot tell you that.
It is an account health metric, not a complete risk management system.
ZeonFX also provides Trade Guard controls including a Trading Lock, Daily Loss Limit and Cool Down Timer. These are behavioural controls rather than substitutes for margin management.
Margin rules are not identical everywhere.
For example, UK FCA rules require retail CFD leverage limits between 30:1 and 2:1 depending on the underlying asset, with mandatory close out when account equity falls below 50% of required margin.
Those FCA rules should not be assumed to apply to every broker or jurisdiction.
Always check the conditions attached to your actual account.
No. Your deposit funds the account. Margin is the portion of equity allocated to support an open leveraged position.
Not necessarily. Free margin describes equity not currently required as margin. Withdrawal availability can depend on open positions, account requirements and broker policies.
It means essentially all available equity is being used to support current margin requirements. Further adverse movement can push the account toward its applicable margin call or stop out process.
Generally, a higher margin level means more equity exists relative to used margin. It does not eliminate market risk.
No. Pip value is mainly determined by the currency pair, position size and account currency. Leverage changes the amount of margin required to support the position.
ZeonFX currently states that negative balance protection applies to retail trading accounts under normal operation.
If you remember only three things, remember these:
Margin is the equity reserved to support your open positions.
Free margin is what remains after used margin is deducted from equity.
Margin level tells you how much equity you have compared with the margin currently being used.
I think margin becomes much easier to understand when you stop seeing it as broker jargon and start seeing it as an account capacity system.
The more exposure you take, the more attention you should pay to equity, free margin and margin level.
And with leveraged trading, waiting until a margin warning appears is not a risk management strategy.
