Open any trading platform and you'll see a wall of numbers: balance, equity, margin, free margin, margin level. They sit in the same corner of the screen, move for different reasons, and mixing them up is a fast way to misjudge your actual risk.
Balance looks like it should show your account's current worth. It doesn't, not while a position is open, equity does that job instead. Margin and free margin decide whether you can open a new trade, and margin level determines whether you're fine or headed toward a margin call.
This guide breaks down what each figure means, how they shift as a trade moves, and where a healthy balance can still leave you exposed.
Key Takeaways
- Balance only reflects deposits and closed trades, it doesn't move while a position is open.
- Equity is your real-time account value, and it's the number brokers use to calculate available margin.
- A healthy balance means little if free margin and margin level are thin, that's what actually triggers a margin call.
What Balance in Trading Actually Means
Open any trading terminal and the first number you'll see is balance. It looks simple, and in a way it is: your account balance is whatever you deposited, plus or minus the realized profit and loss from trades you've already closed, adjusted for withdrawals, commissions, and any other completed transaction.
That's it. It does not include the floating profit or loss sitting in a trade you still have open. That part shows up in equity instead, which we'll get to.
Here's the detail that trips up a lot of new traders: balance stays exactly where it is while a position is open, unless a swap charge or some other adjustment hits the account overnight. You could be up two thousand dollars on an open position, or down two thousand, and your balance won't move an inch until you actually close it.
This single fact explains most of the confusion around account balance meaning in trading platforms, and it's worth sitting with before you touch a leverage calculator or start sizing positions with a lot size calculator.
Fast Fact
- A trader can have a $10,000 balance and still get a margin call, if most of that balance is already locked up as used margin on open positions.
Balance vs Equity vs Margin: Why The Numbers Never Match
Every trading platform, whether it's MT5, cTrader, or something else, shows you a handful of figures that all look related but do different jobs. Get them confused and you'll misjudge how much risk you're actually carrying.
Account Balance
Balance, as covered above, only reflects closed trades. Deposit ten thousand dollars, close a trade at a profit, and balance updates. Have three positions open right now, all in profit? Balance doesn't care.
Equity
Equity is your balance adjusted in real time for whatever is happening in your open positions. The formula is straightforward:
Equity = Balance + Floating Profit − Floating Loss
If you have no open trades, equity and balance are identical numbers. The moment you open a position, they start to drift apart, sometimes by a little, sometimes by a lot depending on your position size and how far price has moved.
According to Babypips' breakdown of the concept, equity is the figure that actually reflects your account's current value at any given second, which is exactly why brokers use it, not balance, to calculate your available margin.
Used Margin
Used margin (also called margin requirement) is the chunk of your funds a broker sets aside as collateral for your open position. It isn't lost or spent, but it's locked up and unavailable for anything else while the trade is live.
Margin Explained: Initial Margin, Maintenance Margin, Margin Requirement
Margin trading meaning boils down to this: you put up a fraction of a position's full value, and the broker covers the rest through leverage. That fraction is set by the leverage ratio your account or instrument is assigned.
Initial Margin
This is the amount required to open a position in the first place. If your leverage in Forex is 100:1, opening a $100,000 position needs $1,000 of margin.
Higher leverage in trading means a smaller initial margin for the same position size, which is exactly why leverage trading feels so accessible and also why it's so easy to overextend an account.
Maintenance Margin
Once the trade is open, maintenance margin is the minimum equity the broker requires you to keep supporting it. Fall below that, and you're heading toward a margin call, not the initial margin, which only applied at entry.
Margin Requirement and Leverage Ratio
Margin requirement is usually expressed as a percentage: 1% margin requirement corresponds to 100:1 leverage, 2% to 50:1, and so on.
Regulators actually cap this in a lot of jurisdictions. ESMA, for instance, restricts retail leverage on major currency pairs to 30:1, with lower caps for more volatile instruments, precisely because higher leverage magnifies both gains and losses.
Any leverage calculator you use should reflect the caps that apply to your account type and region.
Free Margin and Margin Level: The Numbers That Actually Warn You
Free margin is the money left over, available for opening new positions or absorbing further drawdown on existing ones:
Free Margin = Equity − Used Margin
Margin level takes it a step further and expresses your cushion as a percentage:
Margin Level = (Equity / Used Margin) × 100
This is the number brokers actually watch. A margin level above 100% generally means you're fine, though "fine" is relative. Drop toward 100%, and most brokers issue a margin call warning.
Keep falling, and you'll hit the stop-out level, typically somewhere between 20% and 50% depending on the broker, at which point positions start getting closed automatically, starting usually with the largest loss.
A positive balance, even a large one, doesn't guarantee you have enough free margin for a new trade. If most of your equity is already tied up as used margin on existing positions, there might be almost nothing left to open something new, regardless of what the balance figure says.
A Worked Example: Opening, Holding and Closing a Leveraged Trade
Numbers make this concrete faster than any explanation. Say a trader deposits $5,000 and trades on 100:1 leverage.
What The Numbers Show
Notice that balance sits at $5,000 for the whole time the trade is open, only updating once it's closed. Equity is the number doing all the moving. Used margin stays fixed at $1,000 in this example because the position size didn't change, and free margin tracks equity downward as the loss grows.
If price had kept moving against the trader past this point, margin level would have kept dropping toward whatever stop-out threshold the broker sets, and the position would have been closed automatically well before the account hit zero.

What Moves Your Balance And Equity Day To Day
A handful of things nudge these figures around outside of pure price movement.
Spreads, Commissions And Swaps
Spreads cost you the moment you open a position, since you're technically buying at the ask and selling at the bid. Commissions, where the broker charges them separately from spread, come straight off balance when a trade closes.
Swaps, the overnight financing charge (or occasionally credit) for holding a leveraged position past the daily rollover, hit balance directly too, which is one of the rare cases where balance changes without you closing anything.
Deposits, Withdrawals And Broker Adjustments
Deposits and withdrawals are the most obvious factor, adjusting balance immediately. And any adjustment a broker makes, a rebate, a correction, a bonus credit, flows through balance as well.
None of this touches equity separately; equity just reflects whatever balance currently is, plus whatever's floating on open trades at that moment.
If you're serious about trading risk management, it helps to track these costs separately from your trading P/L. A losing month can look worse than it actually was on pure market calls once swaps and commissions are factored in, and a winning month can look better than the underlying strategy deserves for the same reason.
Margin Calls And Stop-Outs: What Happens When Free Margin Runs Out
This is the part of the account that actually matters when a trade goes wrong, since it determines whether you get a warning or lose the position outright.
What A Margin Call Actually Means
What is a margin call, in plain terms? It's a broker's notification that your margin level has dropped to a point where your account can no longer safely support its open positions.
Investopedia's definition frames it as a demand for additional funds or securities to bring an account back up to the required maintenance level, and that's exactly what it is here too, just translated into forex and CFD terms rather than stock margin accounts.
How It Plays Out In Practice
Margin call meaning in a retail forex or CFD context usually plays out like this: margin level drops toward 100%, the platform flags a warning, and you have a choice. Deposit more funds, close some positions to free up margin, or do nothing and hope price turns around.
If it doesn't turn around and margin level keeps falling, you'll hit the stop-out level, and the broker starts closing positions for you, typically the ones with the largest floating loss first, without asking permission.
It's worth building some room here rather than trading margin down to the wire. A position size calculator, used before you enter a trade rather than after, is a cheap way to make sure a single move against you doesn't put your whole account near stop-out territory.
Where To Check These Numbers: MT5 And cTrader
Both major platforms display balance, equity, margin, free margin, and margin level, though they're arranged a little differently.
MT5
In MT5, these figures sit in the Trade tab at the bottom of the terminal, updating live as prices move and as you open or close positions. Margin level specifically is what MT5 references when it decides whether to allow a new order or trigger a stop-out.
cTrader
cTrader shows the same set of figures in its account summary panel, generally with margin level and free margin displayed prominently enough that you don't have to hunt for them mid-trade. Either way, the underlying formulas are identical; only the layout changes.
If you haven't watched these numbers move in a live session yet, opening a demo trading account on either platform costs nothing and gives you a genuine feel for how fast margin level can shift once you're trading with actual leverage.
Common Misconceptions About Balance And Margin
A few ideas about these numbers keep coming up wrong, even among traders who've been at this for a while. Worth clearing them up one at a time.
Balance Reflects Your Account's Real Value
The most common one: assuming balance reflects your account's real, current value. It doesn't, not while you have anything open. Balance stays frozen at whatever it was when your last position closed, no matter how the market is moving right now. Equity is the number that actually does that job, updating with every tick.
A Healthy Balance Protects You From A Margin Call
Second misconception: thinking a healthy balance protects you from a margin call. It doesn't, if that balance is mostly tied up as used margin already.
A large balance sitting alongside an oversized position can be closer to a margin call than a smaller balance with room to spare. What protects you is free margin and margin level, not the number at the top of the screen.
Higher Leverage Always Means More Risk
Third: assuming higher leverage automatically means more risk of ruin regardless of position size. Leverage sets how much margin a position requires, but the actual risk comes from position size relative to account equity.
A trader using 500:1 leverage but sizing positions conservatively can carry less risk than one using 10:1 leverage on an oversized position. Leverage in forex is a tool for capital efficiency, not a risk setting on its own.
Initial Margin And Maintenance Margin Are The Same Thing
Fourth: confusing initial margin with maintenance margin, as if they're one and the same threshold. They're not, and mixing them up leads to bad assumptions about how much room an account actually has.
Initial margin gets you into the trade in the first place; maintenance margin is the separate, lower bar that keeps you in it once you're there.
Conclusion
Balance, equity, used margin, free margin and margin level aren't five versions of the same number. Each answers a different question: what you've banked, what your account is worth right now, how much is tied up, what's left to trade with, and how close you are to trouble. Most account-blowing surprises happen in the gap between these figures.
FAQ
What does balance mean in trading?
Balance is the money in your account from deposits, withdrawals, and profit or loss on closed trades. It excludes anything from open positions.
Does balance include open trades?
No. Open trade profit or loss shows up in equity, not balance.
Why do balance and equity differ?
Equity adjusts constantly for floating profit or loss on open positions, balance only reflects what's already closed.
What happens when equity reaches zero?
Long before that, margin level hits the broker's stop-out threshold and positions get closed automatically.
How do you calculate free margin and margin level?
Free margin is equity minus used margin. Margin level is equity divided by used margin, times 100.
