Unrealized P&L is the current profit or loss on your open positions.
It is called “unrealized” because the position is still open, so the profit or loss has not yet been finalized.
Example:
If you open a position with an Invested Amount of $500 and its current value increases to $550, your Unrealized P&L is +$50.
If its current value falls to $450, your Unrealized P&L is -$50.
Once you close the position, the Unrealized P&L becomes a realized profit or loss.
