Definition
Realized P&L is the profit or loss recorded when some or all economic exposure is closed, settled, expired, or otherwise completed.
In market context
The result generally compares exit value with the applicable entry basis for the closed quantity and then applies the platform’s treatment of fees, financing, and adjustments. Partial closures can realize only part of a position while the remainder continues producing unrealized P&L. Realized P&L affects ledger and performance records, but its value may not equal taxable gain because tax basis and local rules can differ.
