Understanding Key Terms and Formulas
| Term | Definition & Calculation | ||||
|---|---|---|---|---|---|
| Size | Number of contracts held. In One-way mode: long=positive, short=negative. Hedge mode: both positions positive. | ||||
| Entry Price | Adjusts when adding/reversing positions. Coin-margined: (Current Size + Added Size) / (Current Size/Entry Price + Added Size/New Entry Price). USDT-margined: (Current Size×Entry Price + Added Size×New Entry Price) / (Current Size + Added Size) | ||||
| Floating PnL | Coin-margined long: `Face Value × \ | Size\ | × Multiplier × (1/Entry - 1/Mark). USDT-margined short: Face Value × \ | Size\ | × Multiplier × (Entry - Mark)` |
| Floating PnL Ratio | (Floating PnL / Position Margin) × 100% | ||||
| Closed PnL | Similar to Floating PnL formulas but uses close price instead of mark price. | ||||
| Settlement PnL | Uses settlement price instead of mark/close price in PnL formulas. | ||||
| Realized PnL | Closed PnL + Settlement PnL + Trading Fees | ||||
| Realized PnL Ratio | (Realized PnL / Closed Position Margin) × 100% |

Practical Examples
Entry Price Calculation
USDT-Margined Contracts Example:
- Current position: 10 contracts @ 100,000 USDT
- Added position: 5 contracts @ 160,000 USDT
- New entry price:
(10×100,000 + 5×160,000)/15 = 120,000 USDT
Coin-Margined Contracts Example:
- Short position: 10 contracts @ 100,000 USD
- Added short: 5 contracts @ 80,000 USD
- New entry price:
15 / (10/100,000 + 5/80,000) ≈ 92,307 USD
Floating PnL Scenarios
USDT-Margined Long Position:
- Face value: 0.01 BTC
- Size: 10 contracts
- Entry: 100,000 USDT | Mark: 160,000 USDT
- PnL:
0.01×10×1×(160,000-100,000) = 6,000 USDT
Coin-Margined Short Position:
- Face value: $100
- Size: 1,000 contracts
- Entry: 100,000 USD | Mark: 80,000 USD
- PnL:
100×1000×1×(1/80,000 - 1/100,000) = 0.25 BTC
Floating PnL Ratio
- Floating PnL: 6,000 USDT
- Position Margin: 1,600 USDT
- Ratio:
(6,000/1,600)×100% = 375%

Frequently Asked Questions
Q: How does settlement affect my entry price?
A: Settlement replaces your entry price with the settlement price, impacting subsequent PnL calculations.
Q: Why are size values treated differently in One-way vs Hedge modes?
A: One-way mode nets positions (long-short), while Hedge mode tracks separate positions, requiring positive sizing for both.
Q: What's the difference between Floating PnL and Realized PnL?
A: Floating reflects unrealized gains/losses based on current prices, while Realized PnL includes closed trades, settlements, and fees.
Q: How do trading fees impact PnL?
A: Fees reduce your net Realized PnL—they're factored in when positions close or reverse.
Risk Management Notes
- Leverage amplifies both gains and losses—always monitor your Floating PnL Ratio.
- Settlement prices may differ significantly from last traded prices during volatile periods.
- Regularly recalculate entry prices after position adjustments to maintain accurate PnL tracking.
