Navigating cryptocurrency futures trading requires a solid understanding of your open positions, risk exposure, and performance metrics. On OKX, one of the leading digital asset exchanges, users can access comprehensive data to monitor their futures contracts effectively. This guide breaks down how to interpret key elements of your futures holdings — from position value and margin requirements to unrealized P&L and liquidation price — ensuring you make informed trading decisions.
Understanding Key Position Metrics
When you open a futures contract on OKX, several critical indicators appear in your "Current Positions" section. Let’s explore each component in detail.
1. Position Size (Contract Units)
After your order is filled, your position appears under "Current Holdings." You can view the size in either number of contracts (lots) or base currency (e.g., BTC). This toggle allows traders to better visualize their exposure depending on preference.

2. Available to Close (Available Quantity)
This refers to the number of contracts you can immediately close. It's calculated as:
Available to Close = Current Position Size – Frozen for Closing
Orders that are pending execution may temporarily freeze part of your position, reducing the available quantity until they clear.
3. Margin Requirements
Margin is the collateral required to open and maintain a leveraged position. The calculation varies based on contract type and margin mode (isolated or cross-margin).
For USDT-Margined Contracts:
- Cross Margin:
Margin = Face Value × Quantity × Latest Mark Price / Leverage - Isolated Margin:
Margin = Face Value × Quantity × Entry Price / Leverage
For Coin-Margined Contracts:
- Cross Margin:
Margin = Face Value × Quantity / Latest Mark Price / Leverage - Isolated Margin:
Margin = Face Value × Quantity / Entry Price / Leverage
Example:
You open a long position on BTCUSDT with:
- 10x leverage
- 1 BTC equivalent
- Mark price: 10,000 USDT
- Contract face value: 0.0001 BTC
Number of contracts = 1 / 0.0001 = 10,000
Required margin = 0.0001 × 10,000 × 10,000 / 10 = 1,000 USDT
In isolated margin mode, OKX offers an Auto-Margin Add feature. When enabled, the system automatically adds funds to prevent liquidation if your margin ratio drops below the threshold (maintenance margin + close fee). You can disable this for manual control over risk management.
4. Margin Ratio: Measuring Risk Exposure
The margin ratio reflects the health of your position. A lower ratio means higher risk of liquidation.
Initial vs. Maintenance Margin Ratio
- Initial Margin Ratio =
1 / Leverage - Maintenance Margin Ratio: Minimum threshold to keep the position open
Liquidation occurs when:
Margin Ratio ≤ Maintenance Margin + Close Fee Rate
Calculation by Contract Type
USDT-Margined (Isolated):
Margin Ratio = (Fixed Margin + Unrealized P&L) / Position Value
Where: Position Value = Face Value × Quantity × Mark Price
USDT-Margined (Cross):
Margin Ratio = (Balance + Realized + Unrealized P&L) / (Position Value + Frozen Margin × Leverage)
Coin-Margined:
Similar logic applies but uses inverse pricing (divided by mark price).
Practical Example:
- Trade: Long BTCUSDT, 10x leverage
- Entry: 10,000 USDT/BTC
- Contracts: 10,000 (1 BTC)
- Maintenance margin: 1.5%, Close fee: 0.05% → Threshold: 1.55%
Initial margin: 1,000 USDT → Initial margin ratio = 1/10 = 10%
If price drops to 9,010 USDT:
- Unrealized loss = (9,010 – 10,000) × 1 = –990 USDT
- Margin ratio = (1,000 – 990) / (0.0001 × 10,000 × 9,010) = 10 / 9,010 ≈ 0.11%
Since 0.11% < 1.55%, the position is liquidated.
5. Profit & Loss Metrics
Unrealized P&L
This shows gains or losses on open positions, updated in real time.
For USDT-Margined Contracts:
- Long:
(Mark Price – Settlement Price) × Face Value × Quantity - Short:
(Settlement Price – Mark Price) × Face Value × Quantity
For Coin-Margined Contracts:
- Long:
(Contract Value / Settlement Price – Contract Value / Mark Price) × Quantity - Short:
(Contract Value / Mark Price – Contract Value / Settlement Price) × Quantity
These values reset daily at 4:00 PM UTC during settlement.
Realized P&L
Profits or losses locked in after closing a position or during daily settlement.
Total Earnings
Sum of realized and unrealized P&L for the current position.
6. Entry Price and Average Cost
Your average entry price reflects the weighted cost basis of all entries in the same direction.
For USDT contracts:
New Avg Price = (Old Qty × Old Price + New Qty × New Price) / Total QtyExample:
- Existing long: 6 contracts @ $500
- Add: 5 contracts @ $566
→ New average =(6×500 + 5×566)/11= $530
This helps assess break-even levels and adjust exit strategies accordingly.

7. Estimated Liquidation Price
This is the price at which your position will be forcibly closed due to insufficient margin. It depends on:
- Current margin balance
- Maintenance requirements
- Leverage used
You can use the built-in Futures Calculator on OKX to estimate this value before entering a trade.
8. Settlement Base Price
The settlement base price is used to calculate unrealized P&L. It updates daily at 4:00 PM UTC based on the mark price at that time.
Example:
- Open long at $100
- Settlement price set at $120
→ $20 profit per contract is credited as **realized P&L**, and the base resets to $120
Note: This does not affect your actual equity — it only resets accounting for future P&L calculations.
9. Viewing All Positions
Under the "All Positions" tab, you can see every active contract for a given underlying asset (e.g., BTCUSD index), including:
- Weekly
- Bi-weekly
- Quarterly futures
This holistic view helps manage multi-contract strategies efficiently.

Frequently Asked Questions
Q: What triggers automatic liquidation on OKX?
A: Liquidation occurs when your margin ratio falls below the sum of the maintenance margin rate and close fee rate. This typically happens during sharp market movements against your position.
Q: Can I change my margin mode after opening a position?
A: Yes. OKX allows switching between isolated and cross-margin modes dynamically, giving you flexibility in managing risk exposure.
Q: How often is unrealized P&L settled?
A: Daily at 4:00 PM UTC. At this time, unrealized gains or losses are converted into realized P&L and added to your balance.
Q: Does auto-margin add guarantee no liquidation?
A: No. While it helps maintain margin levels, extreme volatility or insufficient funds in your account can still lead to liquidation.
Q: Why does my average entry price change after new trades?
A: Because it's a volume-weighted average. Each new trade adjusts the overall cost basis proportionally based on size and price.
Q: Where can I find historical position data?
A: Visit the "Account History" section under Futures to review past positions, settlements, and transaction records.
