Floating Loss
30-Second Definition
The current, unrealized loss of open positions that have not yet been closed.
What is Floating Loss?
Floating Loss (also known as unrealized loss) is the current negative monetary value of an open trade. Because the position is still active, the loss is subject to change based on real-time price fluctuations and is not finalized until the trade is explicitly closed.
In prop firm trading, floating loss is critically important because it contributes directly to intraday limits. Most prop firms use an equity-based Maximum Drawdown or Daily Loss Limit model, meaning that if your open positions float into deep negative territory and breach a limit, your account is failed—even if the trade later recovers.
Some firms implement specific floating loss rules, such as the 1.2% threshold in the FundingPips Striking System, which penalizes traders for holding too much unrealized heat on a single Trade Idea.
