One note before we start. I’ve written the answers to be broadly true, and prop firms differ, so wherever a detail matters, check your own rulebook. That advice shows up a lot below because it’s the most useful single thing I can say.

Questions about the basics

What is the max daily drawdown?

It’s the largest amount your account is allowed to lose within one trading day. Cross it and most firms close the account. It’s usually set as a percentage of the account, and the day is measured from a fixed reset time. The full explanation is in the prop firm max daily drawdown explained.

Is it the same as the daily loss limit?

In practice, yes. Firms use “max daily drawdown”, “daily loss limit” and “max daily loss” for the same rule. Wording can differ slightly, so read the definition in your terms rather than relying on the name.

How is it different from the overall drawdown?

The daily limit resets every day and stops one bad session. The overall limit covers the account’s whole life and stops a long slide. You can obey one and break the other, which is why you need both floors written down. See daily versus overall drawdown.

Do open trades count toward it?

Under an equity-based rule they do, which means a floating loss can breach the limit before you close anything. If your rulebook doesn’t say, assume they count. The details are in floating losses and open trades.

What happens if I hit it?

That depends on the firm. Many close the account, some pause trading until the next day, and a few allow a paid reset. It’s worth reading that sentence before you buy, not after.

Questions about the calculator settings

What does “limit is calculated on” mean?

It’s the base the percentage is applied to. Some firms use your initial account size, others your balance or equity at the start of the day. In profit those give different dollar limits, so choose the one that matches your rules. Balance-based versus equity-based rules explains how to tell.

What should I enter as start-of-day equity?

Your balance or equity at the moment the firm’s day began, which isn’t always midnight where you live. On the first day it’s just your account size. After that, record it at the reset time.

Should today’s P/L include open trades?

If your firm counts floating losses, yes, enter the total including open positions, as a negative number for a loss. If you’re not sure, include them, since it’s the safer assumption.

What is the soft stop?

A personal stop at 80% of the firm’s limit. It gives you a margin for slippage, wide spreads and your own bad judgement near the real floor. You can set your own level; how to set a personal daily stop shows how.

Why does the calculator hide the results until I press the button?

So that the numbers you see always match the numbers you entered. Change an input and press Calculate again to refresh them.

Questions about risk and position size

How much should I risk per trade?

For most challenge traders, between 0.25% and 1% of the account, chosen by working backwards from the daily limit and the number of losses in a row you want to survive. See how much to risk per trade.

How do I turn my risk into a lot size?

Divide your dollar risk by the stop distance in pips times the value per pip. The stop decides the lots, not the other way round. Position sizing for prop firm challenges has worked examples.

What does “losing trades you can absorb” tell me?

It divides the room you have left by your risk per trade. If the result is below about four, either your risk is too high or the day is already well used.

Does leverage change my daily limit?

No. Leverage affects the margin needed to open a position, not the loss rule. A bigger position still loses the same dollars per pip whatever the leverage.

What if my minimum lot size is too big?

Then the trade is too large for your account at that stop. Skip it or find a tighter, valid stop. Rounding the lot up quietly adds risk. See lot size basics for forex prop traders.

Questions about rules and firms

When does the day reset?

At a time stated in the rules, often midnight on the firm’s server or a market-close time. Daylight saving can move it relative to your local time, so recheck twice a year. See the daily drawdown reset time guide.

Do commissions and swaps count?

Spreads are always in your equity. Commissions and swaps depend on the firm. Swaps and commissions shows what to look for.

Can I trade news?

Some firms allow it, some restrict it, and slippage can make it expensive either way. Read your firm’s news rule and see news trading and daily drawdown before you try.

Does the limit change after I’m funded?

Sometimes. Some firms tighten the limit or change the base after funding or a scaling step. Scaling plans and drawdown covers what to ask.

Can I use the calculator for futures?

Yes. The maths is the same. If your firm states the limit in dollars, divide it by the account size to get a percentage before you enter it.

Questions about mistakes and habits

Why do traders breach the daily limit?

Usually a mix of oversized risk, clustered trades, moved stops, ignored floating losses, news slippage and emotion. Why traders breach the daily loss limit covers nine causes.

What should I do after a loss?

Check how much of the day is used, and decide in advance whether you’re allowed another trade. If you feel the urge to win it back, read revenge trading and the daily loss limit.

Should I keep a journal?

Yes, a small one. Record the trade, the risk, the result, one word for your mood and the share of the daily limit used. Trading journal for prop firm traders shows a layout.

How can I pass a challenge more safely?

Risk small, set a personal stop, take few trades and review weekly. See how to pass a prop firm challenge with small daily risk.

Is my data stored when I use the calculator?

No. Everything runs in your browser and nothing you type is sent to our server.

Questions about specific situations

I’m already down 3% today. Should I keep trading?

Check your own personal stop first. If you set one at 60% to 70% of a 5% limit, you’re at or past it, and the rule says you’re done. If you didn’t set one, 3% is deep enough into the day that most traders do better by stopping and reviewing. The remaining room is real, but so is the pressure to use it.

I’m up 2% today. Does that increase my limit?

Only if your firm calculates the limit on start-of-day equity, and even then only from the next reset. Within the day, your profit gives you more room above the floor, but it doesn’t move the floor itself. It’s also worth being careful: a profit can disappear faster than it arrived.

I have a trade open over the reset. What now?

Note its floating result at the reset time. Under an equity rule, that figure is part of your new start-of-day equity. It’s often simpler to avoid carrying trades across the reset, because the maths gets confusing and mistakes are easy.

My platform equity and the firm’s dashboard disagree. Which is right?

The dashboard decides. Take screenshots of both with the time visible and ask support which figure the daily rule uses. Differences usually come from commissions, swaps or a short update delay.

Can I use the calculator for several accounts?

Yes, but calculate each separately. Account sizes, bases and reset times may differ, and the same trade can have a different effect on each.

Is a bigger account safer?

Not by itself. The percentage rules are the same, and the dollars are bigger, which can make losses feel heavier. The safest account is the one whose risk per trade you can follow calmly.

A short glossary

Balance is the money in your account from closed trades. Equity is balance plus floating profit or loss. Floor is the equity level that triggers a breach. Base is the amount the daily percentage is applied to. Reset time is when the firm starts counting a new day. Soft stop is your own stop for the day, set above the floor. R is your risk per trade as one unit, so a $300 loss on a $300 risk is −1R. Slippage is the difference between the price you expected and the price you got. Keep these handy and most prop firm rulebooks become much easier to read.

A typical day with the calculator

Before the session, enter your account size, the daily percentage, the base and your start-of-day figure, then press Calculate and write down the floor and soft stop. During the session, after each trade, update today’s result and press Calculate again, glancing at the bar and the number of losses you can absorb. If you reach the soft stop, close everything. At the end of the day, note how much of the limit you used. The whole routine takes a few minutes in total, and it keeps the rule in front of you while it still matters.

Numbers worth remembering

A few rules of thumb come up so often that they’re worth keeping on a card. Max daily loss is the base times the percentage. The equity floor is the start-of-day figure minus that. A personal stop at 60% to 70% of the limit is a sensible starting point. Risk per trade between 0.25% and 1%, usually at the lower end for anyone taking several trades a day. A day that uses more than half of the limit is a warning. Three losses in a row is a reason to pause. None of these are laws, and every one of them is easier to follow when it’s written down and visible, instead of living in your head.

Common slips in plain words

Using the wrong base. Forgetting open trades. Reading the reset time as local midnight. Sizing a trade from the lot size you “usually” use. Moving a stop to avoid a small loss and ending up with a big one. Taking a loss and trying to get it back in one trade. Skipping the rulebook because it’s long. If you recognise one of these, you’re in good company, and you’ve just found the first thing to change.

If your question isn’t here

Send it through the contact page, ideally with the account size, the rule as written in your terms and what you expected to happen. A concrete question gets a concrete answer, and the good ones end up on this page for the next person. Questions about a specific firm’s current rules are best sent to the firm itself, since only they can say what applies today.

Where to go next

If you’re brand new, read the explanation of the max daily drawdown first, then the checklist in daily drawdown rules: what to check before you buy. For definitions from a neutral source, Investopedia’s drawdown entry is a good reference, the BabyPips lessons are free and well written, and a live economic calendar helps you plan around news.
