Open Equity vs Closed P&L: Why Prop Firm Risk Feels Different

Open equity is what the account looks like while trades are still open. Closed P&L is what is locked in after trades are closed.

That sounds simple until a prop firm drawdown rule starts reacting to open profit, open loss, or a high-water mark. Then the difference can decide whether a trader is safely inside the rules or sitting on a hidden failure point.

Closed P&L is the locked number

Closed P&L is the result after positions are closed. If a trader takes a $300 win and exits, that $300 is no longer floating.

Closed results are easier to journal because the trade is finished. But closed P&L does not always tell the full account-risk story during the session.

Open equity is the live number

Open equity includes unrealized profit and loss.

If a trader is up $600 on an open trade, the account may look stronger than it did at entry. If that trade reverses to +$100, the trader did not “lose” $500 in closed P&L, but the equity path still changed.

For accounts with trailing or intraday calculations, that path can matter.

The open-profit giveback problem

The trap is treating open profit like protected profit.

A trader may see +$800 floating and mentally count it toward the target. Then the position pulls back, the trader feels like money was taken away, and the next decision becomes emotional.

That is not just psychology. If the account rule tracks open equity or a high-water mark, the giveback may also reduce the account’s room for error.

Why this matters for drawdown

Different accounts can calculate drawdown differently. Some rules focus on end-of-day balances. Some react intraday. Some may consider open equity. Some may lock once a threshold is reached.

Because the exact rule depends on the firm and account type, the safe workflow is to read the rule sheet and then track both numbers:

• ▸current balance;
• ▸open equity;
• ▸closed P&L;
• ▸drawdown floor;
• ▸distance from current equity to the rule boundary.

Do not assume the platform headline number is the only number that matters.

Bucko workflow

Bucko can help by turning open equity and closed P&L into review questions. Did the trader exit according to plan? Did floating profit become a reason to increase size? Did a giveback trigger revenge entries?

The point is not to label every giveback as bad. The point is to know whether the trader followed the planned risk structure.
