Margin close-out is the point at which a leveraged trading account may no longer have enough equity to support its open exposure. The provider can then restrict new orders, cancel pending orders or close positions under the applicable terms. This process is designed to limit further exposure, but it cannot guarantee a particular execution price or prevent every loss.
Start with the account metrics
Four figures usually sit behind a margin decision: balance, equity, used margin and free margin. Balance records completed account activity. Equity adjusts that balance for unrealised profit or loss and other live account items. Used margin is the amount assigned to support open positions. Free margin is the equity remaining after used margin and can change whenever prices, conversions or charges change.
Leverage, Margin and Market Exposure Explained introduces the relationship between notional exposure and the funds committed as margin.
Initial and maintenance margin serve different moments
Initial margin is required when an exposure is opened. Maintenance or ongoing margin determines whether the account can continue supporting open positions. Rates may differ by instrument, size, direction, concentration and market conditions. A provider may also change requirements in accordance with the governing terms.
Understand the margin level
Platforms often express margin level as equity divided by used margin, multiplied by 100. If equity is 2,000 and used margin is 1,000, the displayed margin level is 200%. If unrealised losses reduce equity to 750 while used margin remains 1,000, it becomes 75%. The exact calculation, included balances and thresholds must come from the account documentation.
A margin alert is not the close-out rule
An alert can warn that available margin is declining, but it may not be required and may arrive after the account has moved further. A close-out rule is the contractual or regulatory threshold at which action can begin. Never assume that an email, notification or telephone call will arrive early enough to permit a deposit or manual exit.
What can happen at close-out
When the threshold is reached, a provider may reject new instructions, cancel pending orders, reduce positions or close some or all exposure. The sequence can be automated and may occur without prior notice. Account values can continue changing while orders are processed, particularly where several positions share the same margin pool.
Liquidation order may differ from your expectation
Some systems close the largest loss first, some use a defined account rule and others may select positions according to liquidity or operational constraints. Closing one position can release margin, but it can also crystallise a loss or alter the net exposure of the remaining portfolio. The Client Agreement and platform specification should explain the governing method.

The trigger is not the execution price
A close-out threshold is calculated from account values; it is not a guaranteed dealing price. If the market gaps, spreads widen or available liquidity becomes thin, the next executable price can be materially worse than the level visible when liquidation began. Several positions may be affected before refreshed account values appear.
Why Active Markets Can Still Feel Harder to Fill examines how volatility and order imbalance can change executable liquidity.
Loss can continue below the threshold
Liquidation reduces exposure only as orders execute. Until then, market movement, spread, commission, financing and currency conversion can continue affecting equity. A close-out rule therefore reduces risk but does not create a hard floor under the account balance.
Work through an illustrative example
Assume an account has equity of 5,000 units and uses 2,000 units of margin. Its margin level is 250%. If unrealised losses reduce equity to 1,200, the level becomes 60%. Under a purely illustrative 50% account-level close-out rule, the threshold would be reached at equity of 1,000 if used margin stayed unchanged.
A gap can move equity from above that point to below it before an order executes. The provider may then close one or more positions at available prices. The final balance depends on the execution sequence, fills, costs and any protection that actually applies. This example does not state RockGlobal’s live threshold; the current account terms and margin schedule control it.
Adding funds is not instant protection
A transfer supports the account only after it has been received, cleared and credited. Banking hours, payment screening, currency conversion, limits and provider outages can delay that process. A screenshot or payment instruction is not the same as available equity on the trading server.
Reducing exposure also depends on execution
A manual close, partial close or hedge is still an instruction subject to price, liquidity and platform availability. During a disruption, the instruction may be delayed, rejected or filled away from the displayed price. Position sizing before the event is therefore more controllable than relying on a last-minute action.
Lots, Contract Size, Tick Size and Position Sizing provides the foundations for estimating exposure before an order is placed.
Check the rules before opening exposure
- Confirm the account’s initial margin, maintenance margin and close-out calculation.
- Check whether thresholds apply per account, per position or through another method.
- Understand which balances, currencies, costs and unrealised values enter equity.
- Read how liquidation order, partial fills and market closures are handled.
- Confirm whether negative-balance protection applies and where its limits sit.
- Plan for gaps, payment delays and loss of platform access.
Close-out is a backstop, not a plan
Margin controls react after account capacity has already deteriorated. They do not assess whether an exposure is appropriate, preserve a preferred position or guarantee that a loss stops at the trigger. Keep the current Client Agreement, margin schedule and platform definitions together, and judge exposure using the account as a whole rather than a single trade in isolation.
