Breach (prop firm account)

Updated OCTOBER 6, 2026· Fullport Capital

Definition

A funded account breach is prop-firm language for an account crossing one of its hard rules, most often equity reaching the drawdown floor, which closes that account. At Fullport the rule is a single floor 4% below the starting balance, checked against live equity, with no daily limit on top.

The rule behind the word#

Every Fullport account has one floor, and equity simply needs to stay above it. Equity is cash plus the current value of open positions.

The floor starts 4% below the starting balance: $24,000 on a $25,000 account. It rises only when a UTC day closes at a new high and locks at breakeven once a day closes 4% up.

There is no daily drawdown and no time limit. See max drawdown and trailing drawdown.

What is not a breach?

A day that is too large for the consistency rule just means you keep trading until it is diluted. An order rejected with IMPACT_CAP simply did not fill, and you can resize it.

How traders keep plenty of room#

Size each position from the gap between equity and the floor, not from the balance. On a fresh $25,000 account that gap is $1,000.

Say you hold one memecoin position of $500. Even a 40% drop moves equity by $200, leaving $800 of room. Planning that number before entry is the whole habit; the position size calculator does it for you.

Once a day closes 4% above the start, the floor locks at breakeven and every further dollar of profit adds room. The breakeven lock page shows the trigger for each account size.

Where it is written#

Every rule, with worked examples, is on one public rules page. For prop traders used to two limits, Fullport keeps it to one: a single floor, one step, no daily drawdown and a 24/7 market.

Quick answers

Does a funded account use the same floor as the evaluation?
Yes. A Fullport funded account is issued at the same size with the same 4% floor, which trails at the UTC day close and locks at breakeven. There is no daily drawdown on either.
Is missing the consistency rule a breach?
No. The consistency rule only decides when an evaluation passes. If one day is more than 55% of total profit, you keep trading until further profit dilutes it, and the account carries on as normal.
Does an unrealized loss count toward the floor?
Yes. The floor is measured against live equity, which includes the current value of open positions. That is why traders size each position from the room between equity and the floor.
