Daily loss limits at prop firms: soft vs hard, explained
- A daily loss limit caps how much you can lose in one trading day, usually measured from that day's starting balance.
- A soft limit ends your day. A hard limit ends your account. Know which one you have.
- Many firms count open P&L and fees toward the limit, so you can hit it before you close a trade.
- The trading day follows the futures session, which for the CME products most prop traders use opens at 6:00 pm ET, not midnight.
- Rules vary by firm and change over time. Your firm's current published rules always govern.
The daily loss limit is the rule that is supposed to save you from one terrible session. Used well, it does. Misunderstood, it ends accounts on days when the trader thought they still had room.
Most of the confusion comes from three questions: what happens when you hit it, what counts toward it, and when the day actually starts and ends.
Soft vs hard daily loss limits
Firms handle a breach in one of two ways:
- Soft limit (pause for the day). Hitting the limit closes your positions and locks you out until the next session. The account survives. You lose the day, not the account.
- Hard limit (fail the account). Hitting the limit counts as a rule violation, the same as touching the maximum drawdown. The evaluation or funded account is closed.
Some firms have no daily loss limit at all and rely on the trailing or static drawdown. Others use a soft limit in one stage and a different setup in another. The difference between soft and hard changes how close you can safely trade to the line, so it is worth confirming before your first session, not after your first bad one.
How the limit is measured
The usual starting point is the balance at the start of the trading day, which is normally the previous day's closing balance. Your limit level for the day is that balance minus the daily loss amount.
Hypothetical $50,000 account with a $1,000 daily loss limit.
- Yesterday you closed at $50,400. Today's starting balance is $50,400.
- Today's limit level is $50,400 − $1,000 = $49,400.
- Tomorrow the level resets from wherever today closes. If you finish today at $50,100, tomorrow's level is $49,100.
Because it resets from each day's open, the daily limit does not care about yesterday's profit. A great Monday does not give you a bigger limit on Tuesday.
What counts toward it
This is where most accidental breaches happen. Depending on the firm, the running total can include:
- Realized losses from trades you closed today.
- Open (unrealized) P&L on positions you are still holding. Many firms check your equity in real time, so an open loss counts the moment it appears.
- Commissions and fees. Round-trip costs on every trade add up across a busy session.
Same account, limit level $49,400. So far today:
- Two closed trades: −$250 realized.
- Commissions and fees on those and the current trade: −$30.
- One open position currently showing −$700.
If the firm counts open P&L and fees, you are down $980 and your equity is $49,420. You are $20 away from the limit, which on many contracts is a tick or two. Looking only at your closed trades, you would think you were down $250.
Some firms use a different measure, such as the day's highest balance rather than the starting balance, or only count closed trades. The mechanics above cover the common case. Read the exact wording for your account.
The daily limit and the drawdown floor
The daily limit is not your only line. Your account also has a maximum drawdown floor, and on any given day your real room is whichever is closer.
Your balance is $48,700. Your trailing drawdown floor is $48,000. Your daily loss limit is $1,000.
- The daily limit would allow a loss down to $47,700.
- The drawdown floor is at $48,000, only $700 away.
- Your effective limit today is $700, and touching $48,000 is usually an account failure, even with a soft daily limit.
Near the floor, the drawdown is the rule that matters. The trailing drawdown guide covers how that floor moves.
A personal daily max inside the firm's limit
Many traders set their own daily stop, smaller than the firm's. The firm's limit is where the account gets protected from you. A personal limit is where you decide to stop, while you still have a choice.
A few ways traders set one:
- A fixed dollar amount, for example half the firm's limit.
- A number of losing trades, for example stopping after three losers in a row regardless of the dollar amount.
- A fraction of the drawdown cushion, so the personal limit shrinks automatically when you are close to the floor.
Firm limit $1,000. Personal max $500. Today's starting balance $50,400.
- Personal stop level: $49,900. Firm limit level: $49,400.
- If you stop at your personal level, the $500 between them is space for slippage, a fast market or a position you could not exit cleanly. It is not extra room to trade.
The personal limit only works if it is decided before the session, written down, and treated as final. Moving it mid-session is how it turns back into the firm's limit. If you find yourself trading past it, the guides on revenge trading and trading plans and checklists cover ways to make it stick. Your trade sizing affects how fast you reach it, too; the position size calculator shows the dollar risk per trade for a given stop.
When the trading day starts and ends
Futures do not follow a midnight-to-midnight day. For the CME Globex products most prop traders use, such as equity index, energy, metals and Treasury futures, the session opens at 6:00 pm ET and runs to 5:00 pm ET the next afternoon, with a daily maintenance break from 5:00 to 6:00 pm ET. Sunday's 6:00 pm open starts the trading day for Monday.
Most prop firms align their trading day with that session, so the daily loss limit resets around the evening break, not at midnight. In practice:
- A trade at 8:00 pm ET on Tuesday usually counts toward Wednesday's trading day.
- If you hit a soft limit on Tuesday morning, you can typically trade again after the 6:00 pm ET open that evening, which is technically Wednesday.
- A losing overnight session eats into the next day's limit before the regular open even starts.
Exact reset times vary between firms, and some other products have different hours, so confirm when your firm's trading day rolls over. Journals that group trades by calendar date can disagree with the firm's view of "today" for the same reason.
Keeping track
The simplest habit is to write down three numbers before each session: today's starting balance, the firm's limit level, and your personal stop level. Add the drawdown floor if you are within a day's loss of it.
TradeHarbor's presets for 14 futures prop firms include each firm's daily limit, and the account status view applies it to your imported trades. The prop firm rules pages list each firm's daily loss limit with the source it came from and the date it was last checked.
Whichever you use, the firm's current published rules and your live account dashboard are what count. Rules change, and the firm's own numbers always govern.
