The short answer
A prop firm daily loss limit (daily drawdown) is the most your account may lose in one trading day before it is closed. It is usually a percentage, such as 5%, and resets once a day at a time the firm sets. The detail that decides whether you survive is what it measures: closed trades only (balance-based) or open trades too (equity-based), and from which starting level.
On gold the maths is unforgiving. A 5% limit on a $10,000 account is $500, which is a $5 move at 1 lot or a $50 move at 0.1 lot, because one lot of XAUUSD is 100 oz and every $1 is worth $100 per lot.
How firms measure the daily limit
The same “5% daily loss” can mean several different things. These are the variants you will meet, described generically:
| Variant | The day’s limit level is… | Counts open trades? |
|---|---|---|
| Fixed amount, balance-based | Balance at reset minus 5% of the initial account size | No, closed trades only |
| Fixed amount, equity-based | Balance at reset minus 5% of the initial account size | Yes, floating P/L counts |
| Higher of balance or equity | The higher of balance or equity at reset, minus the limit | Yes |
| Percentage of current level | 5% of the balance or equity at reset, not of the initial size | Usually yes |
Two more details change the outcome:
- Reset time and time zone. Many firms reset near the 5 pm New York daily break; others use a different clock. A trade held across the reset carries its open profit or loss into the next day’s calculation.
- Commission and swap. Most firms count them in the daily loss. On gold, commission is charged per lot and swap can be large on a held position.
The maths at 0.1, 0.5 and 1 lot
Assume a gold contract of 100 oz per lot, quoted to two decimals, so $0.01 = 1 point = $1 per lot and $1 = 100 points = $100 per lot. Check the contract size in your platform’s specification.
$10,000 account, 5% daily loss = $500
| Size | Value of $1 | Gold move to lose $500 | In points |
|---|---|---|---|
| 0.10 lot | $10 | $50.00 | 5,000 |
| 0.50 lot | $50 | $10.00 | 1,000 |
| 1.00 lot | $100 | $5.00 | 500 |
$100,000 account, 5% daily loss = $5,000
| Size | Value of $1 | Gold move to lose $5,000 | In points |
|---|---|---|---|
| 0.10 lot | $10 | $500.00 | 50,000 |
| 0.50 lot | $50 | $100.00 | 10,000 |
| 1.00 lot | $100 | $50.00 | 5,000 |
Set those numbers next to how far gold actually travels. Our daily move study found an average daily range of about $77 on data to 19 October 2026. Our CPI day study found the 8:00 to 9:00 am New York hour on CPI days had a median range of $29.6, and the NFP study found $30.1 for jobs-report hours. So:
- On a $10,000 account, 1 lot has room for a $5 move: a fraction of a quiet hour.
- At 0.5 lot, a median CPI or NFP hour is three times the whole daily limit.
- At 0.1 lot, the limit covers about two thirds of an average day’s range. That is the scale at which a stop-based plan can work.
How a fast gold move breaches the limit
The floating-loss trap. $10,000 account, equity-based 5% limit, so the day’s floor is $9,500. You buy 0.50 lot at $4,000.00 with a stop at $3,990.00, a planned loss of $10 × 50 oz = $500 before costs. You think that fits exactly.
Then US data lands. Gold drops to $3,988.00 in seconds, your stop fills with slippage at $3,989.20, and the loss is $10.80 × 50 = $540 plus commission. Equity touched $9,460: breach, even though your plan “risked 5%”.
Yesterday’s profit counts against you. $100,000 account, limit level = the higher of balance or equity at the reset, minus $5,000. You hold 1 lot long from yesterday, $15 in profit (+$1,500) at the reset, so today’s floor is $101,500 − $5,000 = $96,500. Gold falls $50 from the reset price: equity is $96,500 and the account is breached. Measured from your entry, the trade is only $35 down, a $3,500 loss, well under 5%.
Both examples show the same lesson: the limit is a price level on your equity, not a plan. Gaps, slippage, spread widening and open profit at the reset all move you closer to it.
Common ways traders breach the daily limit
- Sizing to the limit. Risking the whole daily allowance on one trade leaves no room for slippage or costs.
- Several trades at once. Three positions each risking 2% are one 6% position when gold moves against all of them.
- Averaging down. Adding to a loser on a fast gold day doubles the speed at which equity falls.
- Holding through news. A stop is not filled at its exact price in a spike; see gold slippage explained.
- Holding across the reset. Open profit can raise tomorrow’s reference level at some firms, and the daily-break spread can push equity briefly lower.
- Chasing losses. After a losing morning, the remaining room is smaller but the urge to trade bigger is stronger. A hard stop for the day helps more than willpower.
Build a buffer you can live with
A buffer is a personal limit set well inside the firm’s limit. A workable approach:
- Personal daily stop at half the firm’s limit. On a 5% limit, stop trading for the day at −2.5%.
- Risk per trade small enough for a losing streak. At 0.5% risk you can lose five trades before reaching your 2.5% personal stop.
- Size from the stop, not the account. Use the position size calculator with your stop distance in dollars.
- Allow for slippage on gold. Assume a stop can fill a dollar or more beyond your level in fast markets and size for that.
- Flat or reduced before high-impact news, unless your plan is built for it and your firm allows it.
The prop challenge calculator shows how many losses in a row each rule allows at your chosen risk per trade. To see the room you have right now, the prop drawdown buffer tracker turns today’s starting balance or equity, your current equity and the limit into dollars left and the gold move that would breach it at 0.01 to 1 lot.
What to check in your own firm’s terms
- Is the daily limit balance-based or equity-based?
- Is it a percentage of the initial size or of the balance or equity at the reset?
- If equity counts, is the reference the higher of balance and equity?
- What is the reset time and in which time zone? Convert it to your own.
- Do commission and swap count?
- Is a breach automatic on a touch, or checked at the close of the day?
- Is there a worked example in the terms? If not, ask for one in writing.

Frequently asked questions
What is a daily loss limit in a prop firm?
It is the maximum amount your account may lose within one trading day, as defined by the firm. If your balance or equity falls below that day’s limit level, the account is breached, usually automatically. It is often expressed as a percentage of the starting balance, for example 5%, and it resets once a day at a time the firm sets.
Does the daily loss limit include open trades?
At many firms, yes. An equity-based limit counts floating losses on open trades in real time, so a trade that dips through the limit and then recovers can still breach the account. A balance-based limit counts only closed trades. Read the exact definition in your firm’s terms.
How much can gold move before a 5% daily limit is hit?
It depends on your size. On a $10,000 account a 5% limit is $500. With one lot of XAUUSD worth $100 per $1 move, that is a $5 move at 1 lot, $10 at 0.5 lot and $50 at 0.1 lot. On a $100,000 account the moves are ten times larger for the same lot sizes.
When does the daily drawdown reset?
Each firm sets its own reset time and time zone. Many reset around the daily break of the market, near 5 pm New York time, but some use midnight in another zone. Find the exact time in the terms and convert it to your own time zone.
Is the 5% daily loss based on starting balance or current balance?
It varies. Some firms take a percentage of the initial account size, so the dollar amount never changes. Others take a percentage of the balance or equity at the daily reset, so the amount grows or shrinks with the account. Some use whichever of balance or equity was higher at the reset.
