The common formula is simple: margin level = equity / used margin x 100. If equity is $24,800 and used margin is $6,200, margin level is 400%. As equity falls or used margin rises, margin level drops.
The MT5 margin terms
| Term | Meaning |
|---|---|
| Equity | Balance plus floating profit and loss. |
| Used margin | Collateral required by current open positions. |
| Free margin | Equity minus used margin. |
| Margin level | Equity divided by used margin, shown as a percentage. |
Why margin level matters
Margin level is a pressure gauge. A falling margin level means the account has less room to absorb open-position movement. For EAs that add positions, hedge, grid or recover, this number can change quickly.
Prop firm accounts may focus more on drawdown than margin, but margin level still matters because low margin can force broker-side risk events before a trader has time to respond.
Alert thresholds
There is no universal safe margin level because brokers, leverage and strategies differ. The useful pattern is staged alerts. A high-level warning gives context. A lower threshold becomes urgent. A critical threshold means the trader should inspect the account immediately.
Monitor margin with equity and drawdown
Margin level alone does not explain the whole account. Combine it with equity drawdown, open P/L, exposure by symbol and terminal heartbeat. For the full account model, read How to monitor MT5 accounts.
