Understanding how to calculate profit and loss (P&L) for options is essential for traders navigating derivatives markets. This guide breaks down the process across different margin modes, helping you optimize your trading strategy.
1. Single-Currency Margin: Cross Margin
In single-currency cross margin mode, users can only open short options positions. For long positions, switch to isolated margin (see Section 3).
Key Metrics for Options Positions
| Term | Definition |
|---|---|
| Total Positions | Positive for long positions, negative for short. |
| Options Value | = Total Positions × Mark Price × Contract Multiplier × Contract Value |
| P&L (Unrealized) | = (Mark Price − Avg. Open Price) × Total Positions × Contract Multiplier × Contract Value |
| P&L Ratio | Long: (Mark Price − Avg. Open Price) / Avg. Open Price Short: (Avg. Open Price − Mark Price) / Avg. Open Price |
| Initial Margin | Long: 0. Short: Refer to 👉 Options Margin Calculation Guide. |
| Maintenance Margin | Long: 0. Short: Refer to the above guide. |
2. Multi-Currency Margin: Cross Margin
Under multi-currency cross margin, traders are similarly restricted to short options positions. Long positions require isolated margin (Section 3).
Position Metrics (Identical to Single-Currency)
👉 Review the table in Section 1 for identical definitions of Total, Options Value, P&L, and margin requirements.
3. Isolated Margin Mode (Single/Multi-Currency/Portfolio)
Isolated margin allows both long and short options positions, with separate margin pools for each position.
Isolated Position Metrics
| Term | Definition |
|---|---|
| Margin (Balance) | = Initial Margin + Manually Adjusted Margin |
| Margin Ratio | = Margin Balance / (Maintenance Margin + Liquidation Fee) |
| Other Metrics | Identical to Sections 1–2 (Total, Options Value, P&L, etc.). |
FAQs
Q1: Why can’t I open long positions in cross margin modes?
A: Cross margin prioritizes risk management by restricting long options positions, which require full premium payment upfront. Use isolated margin for long positions.
Q2: How is P&L calculated for short options?
A: P&L for shorts reverses the long formula: (Avg. Open Price − Mark Price) × Positions × Multiplier × Contract Value.
Q3: What’s the difference between initial and maintenance margin?
A: Initial margin secures the position at opening; maintenance margin is the minimum equity needed to avoid liquidation.
Key Takeaways
- Cross margin modes limit traders to short options; isolated margin enables longs.
- P&L formulas vary by position direction but hinge on mark price vs. average open price.
- Margins for longs are zero; shorts require dynamic calculations.
