Currency trading presents both challenges and opportunities for informed investors. Understanding your profits and losses (P&L) is critical, as it directly impacts your margin balance and available trading funds. This guide breaks down key concepts like realized vs. unrealized P&L, pip calculations, and margin management.
Key Takeaways
- P&L awareness affects margin balances and trading capacity.
- Forex trades are marked to market in real time, reflecting unrealized gains/losses.
- Position size × pip movement = actual profit/loss.
- Long/short positions determine P&L direction.
Realized vs. Unrealized Profit and Loss
Unrealized P&L
- Reflects open positions with fluctuating values.
- Updated via mark-to-market pricing (current closing value).
- Impacts margin balance dynamically.
Realized P&L
- Locked in upon closing a position.
- Increases/decreases margin balance based on profit/loss.
Formula:
Margin Balance = Initial Margin + Realized P&L + Unrealized P&L
Calculating Profit and Loss
Step-by-Step Process
- Identify position size (e.g., 100,000 GBP/USD).
- Track pip movement (e.g., 15 pips).
- Calculate P&L: Position Size × Pip Movement.
Example:
- Long GBP/USD: Price rises 15 pips → $150 profit (100,000 × 0.0015).
- Short GBP/USD: Price drops 20 pips → $200 profit (100,000 × 0.0020).
| Position | Price Movement | Outcome |
|---|---|---|
| Long | +15 pips | +$150 profit |
| Short | -20 pips | +$200 profit |

Currency Denomination
- P&L is in the quote currency (e.g., USD for GBP/USD).
- Convert non-USD P&L using current exchange rates.
Example: CHF 100 profit ÷ USD/CHF rate (0.8445) = $118.41.
Forex Trading FAQs
1. What is Forex trading?
Forex involves buying one currency while selling another to profit from exchange rate fluctuations.
2. How does mark-to-market work?
MTM values open positions at current market prices to reflect unrealized P&L.
3. What’s a pip?
A pip is the smallest price move in forex (e.g., 0.0001 for most pairs).
4. How does leverage affect margin?
Higher leverage (e.g., 100:1) reduces required margin per trade (e.g., $1,000 for 100,000 USD/CHF).
Risk Management Tips
- Monitor margin requirements to avoid liquidation.
- Use stop-loss orders to cap losses.
- Limit leverage to align with your risk tolerance.

The Bottom Line
While brokers automate P&L calculations, understanding the mechanics empowers better trading decisions. Always assess position size, pip values, and leverage to optimize risk-reward ratios in forex markets.
