Realized P&L is the profit or loss that becomes permanent when you close a trade — it updates your account balance immediately and cannot be reversed by future price movement. Unrealized P&L (also called floating P&L or open P&L) is the mark-to-market value of positions still open, calculated tick by tick based on current price versus your entry. The two numbers look similar on a trading platform but behave in completely different ways — and confusing them is one of the most costly mistakes a prop firm challenge trader can make.
Key Takeaways
- Realized P&L permanently changes your balance only when a trade is closed; unrealized P&L can reverse to zero in seconds.
- Most prop firms (FTMO, Funded Next, MyFundedFX) calculate drawdown on equity — Balance + Unrealized P&L — meaning open floating losses count against your limit immediately.
- Loss aversion causes traders to hold unrealized losses far longer than they hold winners, a behavioral pattern that compounds risk on funded accounts.
How Realized vs Unrealized P&L Works
When you open a trade, your balance does not change. Instead, a floating P&L figure appears that moves with price. The moment you close the trade, that floating figure converts to realized P&L: your balance updates, the unrealized number disappears, and the result is locked in regardless of where price goes afterward.
The relationship between these figures and your account equity is:
Equity = Balance + Unrealized P&L (all open positions combined)
This formula is the foundation of how prop firms measure risk. A trader with a $100,000 balance and -$8,000 in open floating losses has equity of $92,000 — and is already 80% of the way to breaching a 10% maximum drawdown limit, even without closing a single trade.
Swap and rollover fees add a practical wrinkle: overnight financing charges accumulate as unrealized adjustments during the trading day, but they convert to realized P&L when the position closes. On a large multi-day position, swap costs can meaningfully erode what looks like a floating profit.
Quick Reference
| Aspect | Detail |
|---|---|
| Formula | Equity = Balance + Unrealized P&L |
| Realized triggers | Trade close, position liquidation |
| Unrealized range | Fluctuates from current open; can be positive or negative |
| Tax trigger | Realized only (varies by jurisdiction) |
| Prop firm drawdown | Calculated on equity, not balance |
Practical Example
A trader on a $100,000 FTMO Phase 1 challenge (10% max trailing drawdown = $10,000 buffer) enters the London session with two trades:
- Long 2 lots EUR/USD at 1.1050 — price moves to 1.1100, generating +50 pips × $10/pip × 2 lots = +$1,000 unrealized gain.
- Short 1 lot GBP/USD — immediately moves -60 pips against them = -$600 unrealized loss.
Equity at this point: $100,000 + $1,000 − $600 = $100,400.
The trader closes the EUR/USD trade at 1.1100. Balance updates to $101,000. The GBP/USD trade remains open at -$600 unrealized. Equity is $100,400.
Now GBP/USD continues moving against the position, reaching -$10,500 in unrealized losses. Equity drops to $101,000 − $10,500 = $90,500 — a $9,500 drawdown from the $100,000 starting equity, breaching the $10,000 limit.
The account is stopped out. Balance showed $101,000 (net profitable on closed trades), yet the challenge was failed — entirely because of unrealized losses on the open GBP/USD position.
Realized P&L is profit or loss locked in when you close a trade, permanently changing your balance. Unrealized P&L is the floating value of open positions that changes every second and can disappear completely if price reverses before you close.
Common Mistakes
- Ignoring equity when monitoring drawdown. Watching your balance and ignoring equity is the single most dangerous habit on a prop firm account. Always monitor equity — that is the number that triggers a breach.
- Counting unrealized profits as performance. A $2,000 floating gain is not realized profit. Traders who size up or add positions based on unrealized gains often watch those gains reverse entirely. Average win statistics should only include closed trades.
- Holding losers to avoid realizing the loss. Research by Barber and Odean (UC Davis) found retail investors hold losing positions approximately 1.7x longer than winning ones. On a funded account, this disposition effect is especially destructive because floating losses consume equity headroom in real time.
- Misreading performance during drawdowns. A positive balance with a deeply negative unrealized position creates a false sense of security. Your equity curve should reflect realized P&L only — that is the honest measure of trading performance.
How PipJournal Tracks Realized P&L
PipJournal aggregates only closed trades when calculating performance metrics — average win, average loss, win rate, and expectancy are all built from realized P&L only, which prevents floating positions from distorting your actual results. The dashboard separates balance from equity views so prop firm traders can monitor both numbers simultaneously and catch drawdown risk before it becomes a breach.
