Daily drawdown vs trailing drawdown: the same two days under three rules

Daily drawdown vs trailing drawdown comes down to where losses are measured from. A daily drawdown caps how far an account can dip in one day, measured from the day's open, and resets every day. A trailing drawdown limits how far you fall from your best point so far, and never resets.

Both end an account when losses go too far. The trailing floor follows your high-water mark up and never comes back down; the daily limit starts fresh at a fixed hour.

Why do prop firms use both?

Many prop firms run both at once, which is where most confusion comes from. The daily limit catches one bad session; the trailing limit catches a slow bleed over a week. Others drop the daily limit and keep a single overall floor.

Which kind you are under changes how you size, when you stop for the day, and whether a winning trade you did not close can still hurt you.

Intraday vs end-of-day trailing drawdown: what is the difference?

Trailing drawdowns come in two very different versions. An intraday (equity-based) trailing drawdown moves up with every new peak in live equity, including unrealized profit on open positions. An end-of-day trailing floor moves only when a day closes at a new high.

The difference sounds technical. On a volatile coin it decides whether a round trip from +$900 back to +$200 costs you anything.

Take a $25,000 account with $1,000 of loss room, and run one trader's two days through three rule sets. Rules A and B are hypothetical, built with the same $1,000 so that only the mechanics differ. Rule C is the floor Fullport actually uses.

• Rule A, daily limit plus static floor: equity may not fall more than $500 below the day's opening balance, and never below a fixed $24,000.
• Rule B, intraday trailing: the floor sits $1,000 under the highest live equity ever reached, open positions included.
• Rule C, end-of-day trailing with a breakeven lock: the floor sits $1,000 under the highest realized balance at a 00:00 UTC close, and stops at $25,000 once a close reaches $26,000.

Day 1. A launch runs and open equity peaks at $25,900. The trader takes some profit late, gives the rest back on a second coin, and the day closes at $25,200.

Day 2. An early loss drags equity down to $24,650 before two better trades bring the day to a close at $25,600.

The trader made money over the two days in all three versions: +$600 by the end of Day 2. Two of the three rules ended the account anyway.

Rule A was hit because a single morning lost more than $500 from the day's open. Rule B was hit because the floor had already climbed $900 on profit that was never banked, leaving $300 of room going into a volatile session.

Neither is stricter in general; each is strict about a different pattern. A daily limit is harsh on bad mornings: a deep intraday dip can hit the limit even if you recover by the close, while a losing streak spread thinly across many days can go on for a long time.

A trailing limit is harsh on giving back gains: it ignores which day losses happen on and counts only the distance from your peak.

Why is intraday trailing drawdown so hard on memecoins?

The intraday version adds a third trap: unrealized peaks. Every time an open position spikes, the floor moves up behind it, permanently. Memecoins spike and retrace constantly, so an equity-based trailing floor tends to climb on paper profit you never collected.

End-of-day trailing removes that trap by only counting realized balance at the close. Here is how each type treats the common patterns:

• Deep dip, recovered by the close: a daily limit and an intraday trailing floor can both be hit. An end-of-day floor is untouched as long as equity stays above it.
• Open position spikes, then retraces: an intraday trailing floor rises on the spike. A daily limit and an end-of-day floor are unaffected.
• Small losses over many days: a daily limit rarely triggers. Both trailing types trigger once the sum reaches the room.
• Big realized winning day: a daily limit is unaffected. An intraday floor rises during the day; an end-of-day floor rises at the close.
• Resets: a daily limit resets every day. A trailing floor never does.

Fullport uses Rule C and nothing else: one floor, 4% of the starting balance, no daily drawdown. The floor opens 4% under the start, rises only when a UTC day closes on a new realized high, and locks permanently at breakeven once a close is 4% above the start.

Equity is compared with the floor on every price tick, open positions included, while the floor itself only ever moves at the close.

What changes once the floor locks?

Before the lock, your room is always $1,000 below your best close on the $25,000 account. After it, every dollar above $25,000 is room, so a funded account that closes at $27,200 has $2,200 between equity and the floor.

The drawdown calculator tracks the floor for any sequence of closes, and the position size calculator sizes a trade against it.

Does trailing drawdown reset after a payout?

Not at Fullport. On a funded account, payouts reset the balance to the withdrawal buffer (starting size plus 4%), and the floor stays locked at breakeven.

1. Is it measured on equity or balance? Equity includes open positions and is checked continuously. Balance only moves when you close.
2. When does the day reset, and in which time zone? A daily limit is only as clear as its reset hour.
3. Do unrealized gains move a trailing floor? If yes, every spike you do not sell raises the bar.
4. Does the trailing floor ever stop? A floor that keeps trailing forever means your room never grows past the original amount.
5. What happens after a payout? Check whether the floor and the high-water mark are reset, kept, or recalculated from the new balance.

If a firm's answers to those five are not in the published rules before checkout, assume the strictest reading. For static and trailing limits side by side, see prop firm drawdown rules explained.

If you are coming from a forex or futures firm, the Fullport version is short: one step, one end-of-day floor, no daily drawdown, no time limit, and a market that trades 24/7 with no Friday close.
