Trailing vs Static Drawdown: Prop Firm Rules Explained

Static drawdown is a loss limit fixed at your starting balance: it never moves. Trailing drawdown is a loss limit that follows your account up: every new high in equity lifts the floor you must stay above. On the same trades, a trailing limit can end an account that a static limit would have kept alive, which is why the type of drawdown matters as much as the percentage.

This guide explains both, the daily loss limit that sits on top of them, and how to trade so neither one ends your challenge.

Key takeaways

• —Static drawdown sets one floor (for example $90,000 on a $100,000 account) that never changes.
• —Trailing drawdown moves the floor up with your highest equity, so profit you give back counts against you.
• —Intraday trailing can count open profit you never banked; end-of-day trailing only updates when the day closes.
• —The daily loss limit is a separate rule, and at many firms it counts open trades as well as closed ones.
• —In our simulation of 40,000 challenges per risk level, risking 0.5% a trade passed 98% of the time; risking 2% passed 47%.

What is drawdown in a prop firm challenge?

Drawdown is how far your account falls from a reference point. In a prop firm challenge it is a hard rule: fall below the limit once and the account fails, whatever your profit was before.

Most challenges set two limits at once: a maximum drawdown (also called max loss or overall loss limit) for the life of the account, and a daily loss limit for each trading day. The maximum drawdown comes in two types, static and trailing.

Static drawdown: a floor that never moves

With static drawdown, the floor is your starting balance minus the limit, and it stays there.

On a $100,000 account with a 10% static limit, the floor is $90,000. Grow the account to $110,000 and the floor is still $90,000, so you now have $20,000 of room. Profit gives you more space, which makes static drawdown the more forgiving of the two.

Trailing drawdown: a floor that follows your high

With trailing drawdown, the floor sits a fixed distance below the highest point your account has reached. Every new high lifts it; it never moves back down.

Same $100,000 account, same 10% limit, but trailing. Your equity climbs to $106,000, so the floor rises from $90,000 to $96,000. If equity then falls to $95,000, the account fails, even though a static rule would still have left you $5,000 of room.

The practical effect: under a trailing rule, profit you give back is treated like a loss. Your real room is always measured from your best moment, not from where you started.

Intraday trailing vs end-of-day trailing

Firms calculate the trailing high in two main ways, and the difference is large.

• —Intraday (equity) trailing follows your equity tick by tick, open trades included. A trade that is up $3,000 at its best lifts the floor by $3,000, even if you later close it at breakeven.
• —End-of-day trailing only updates the floor from your balance or equity when the trading day closes. Swings inside the day do not move it.

Intraday trailing is the strictest version: open profit you never banked can still tighten your limit. If your firm uses it, a big winner you let turn into a scratch costs you room.

When the trail stops

Some firms stop trailing once the floor reaches the starting balance (or a set amount above it). From then on the floor is fixed, and the account behaves like a static one at breakeven. Check whether yours does, and at what level, because it changes how much a strong first week protects you.

The daily loss limit is a separate rule

The daily loss limit caps how much you can lose in one trading day, usually as a percentage of the starting account size. A common setting is 5%: $5,000 on a $100,000 account. It applies on top of the maximum drawdown, and it is the rule most challenges fail on.

Two details decide how it behaves:

• —Equity or balance. At many firms, FTMO included, the daily limit is measured on equity, which includes the floating loss of open trades. A position that is down $5,400 on a $100,000 account breaks a 5% daily limit before it is ever closed. Balance-based firms only count closed trades.
• —The reset. Each firm resets the day at a set time, and measures the day's loss from a reference point at that reset, such as the day's starting balance. Know the exact time and reference, because a trade held across the reset is counted differently from one closed before it.

Static vs trailing at a glance

How many losing trades can you afford?

The cleanest way to read any limit is in losing trades. Divide the limit by your risk per trade:

Three losers in a row at 2% risk is a −6% day, past a 5% daily limit. For a strategy that loses 6 trades in 10, three losses in a row happen on roughly one day in five. That is why the daily limit, not the strategy, ends most challenges.

We tested this directly. We ran one strategy (4 winners in 10, each winner twice the size of each loser, three trades a day) through 40,000 simulated challenges at each risk level, under typical two-step rules: a 10% then 5% profit target, a 5% daily limit and a 10% maximum loss.

• —Risking 2% a trade passed 47% of the time, and every failed run hit the daily limit, not the overall one.
• —Risking 1% passed 87%.
• —Risking 0.5% passed 98%, taking a median of 27 trading days instead of 2.

One caveat: small risk protects an edge, it does not create one. The same simulation with a coin-flip strategy (50% winners, 1:1) passed only about half the time, even at 0.5% risk. You can walk through the full simulation in our free lesson on passing a prop firm challenge.

How to trade inside a trailing drawdown

• —Measure room from the floor, not the start. After a good run under a trailing rule, your room is the distance to the new floor. Size from that.
• —Treat open profit as not yours yet. Under intraday trailing, a winner's peak tightens your limit. Decide in advance where you take partial profit or move the stop.
• —Set a personal daily stop inside the firm's. For example −2% against their −5%, so one bad day can never end the account.
• —Stop once you hit the target. More risk after the target can only take the pass away. If there is a minimum-days rule, finish it with the smallest trades allowed.
• —Know the reset time and the reference point. Write them down before the first trade.
• —Size every trade from the stop. Find where the stop belongs on the chart, then work out the size. The free position size calculator does the arithmetic for US30.

Watching the limits on your chart

Doing this arithmetic live, with trades open, is where mistakes happen. Prop Guard, part of Candle Decoder for MT5 on the Pro plan, watches your account against your firm's limits every second. You enter the account size, daily loss limit, maximum drawdown, whether it is static or trailing, and the daily reset hour.

It starts in Warn mode and alerts you at 70% and 90% of a limit, on screen and optionally on your phone. If you switch on Enforce mode, it closes every position at a limit (minus a safety buffer) and keeps closing new ones until the lock ends. Its trailing mode follows your highest equity, the strict intraday version, so if your firm trails on end-of-day values or stops trailing at the starting balance, it errs on the safe side. It only works while MetaTrader 5 is running, and no tool can guarantee you stay within a firm's rules.

The short version

Static drawdown gives you a fixed floor; trailing drawdown moves it up with every high, and the intraday version counts profit you never banked. Read which type your firm uses, how it treats open trades, and when the day resets. Then risk small enough (0.5% to 1% a trade) that no single day, and no give-back, can reach the limit.
