Two traders lose the exact same dollars on the exact same day. One is fine; the other is breached and locked out. The difference isn’t skill — it’s how their firm measures the daily loss limit, and whether they understood it before the trade.
Balance-based vs equity-based daily loss calculation
The single most important question about your daily loss rule: is it measured from balance or from equity? They are not the same, and the gap between them is your open, floating P&L.
- Balance is your account after only closed trades. Open positions don’t touch it.
- Equity is your balance plus the current mark-to-market value of everything you’re holding right now.
If your firm measures the daily limit against equity, then an open loser counts against you the moment it moves against you — even if you never close it. A position sitting at a large unrealized loss can breach the limit while you’re still “waiting for it to come back.” If the firm measures against balance, only realized losses count, and a floating drawdown that recovers before you close never registers.
| Measured against | What counts | The trap |
|---|---|---|
| Balance | Closed trades only | A recovering floater doesn’t breach, but a cascade of closed losses does |
| Equity | Closed + open P&L, live | An unrealized spike can breach before you ever hit “close” |
Most futures-style programs watch equity in real time. Assume equity-based unless your rulebook explicitly says otherwise — it’s the stricter reading and the safer default.
Intraday floating loss vs end-of-day settlement
Even within equity-based rules, when the limit is checked matters. Some firms evaluate the breach intraday, tick by tick — the instant your equity dips past the floor, you’re out, regardless of where you close. Others check only at a settlement snapshot, so a deep intraday dip that recovers before the cutoff doesn’t count.
Never assume the friendlier version. If you don’t know for certain, treat the limit as a live tripwire that can fire on a single bad tick. This is exactly the scenario that catches traders during news spikes, where a momentary wick can breach an intraday rule and immediately reverse — the recovery doesn’t save you if the breach already registered.
How the starting point resets each trading day
Your daily floor is anchored to a starting value that resets each trading day — but the reset time and the anchor differ:
- The reset time is usually a fixed platform hour (often a US market close boundary), not your local midnight. Trades held across that boundary belong to the new day.
- The anchor is typically your balance or equity at the reset — but some firms lock the day’s starting balance and don’t let intraday profit raise your floor.
That last detail is the sneaky one. If you’re up on the day and your floor is still pinned to the morning’s starting balance, you have more room than it feels like. If your floor floats up with intraday profit at some firms — it usually does not for the daily rule — you’d have less. Confirm which anchor your firm uses, because it changes how much cushion today’s winners actually buy you.
Where open positions count against the limit
Tie the threads together and the danger zone is clear: an open position, under an equity-based intraday rule, is a live liability against your daily floor. Holding a loser and hoping isn’t a neutral act — every tick against you is spending real distance to the limit.
This is distinct from your maximum or trailing drawdown, which governs the account’s lifetime low-water mark rather than a single day. The two limits interact: a day that doesn’t breach the daily rule can still ratchet a trailing drawdown tighter, leaving you with less room tomorrow. Know which one is nearer before you size a trade.
Firm-by-firm differences to verify in your rulebook
The mechanics above vary meaningfully between programs, and they change over time — so verify the current version in your own dashboard rather than trusting any summary, including this one. Points worth confirming for your specific account type at firms like FTMO or MyFundedFutures:
- Balance-based or equity-based daily limit
- Intraday tripwire or end-of-day settlement check
- The exact reset time and time zone
- Whether the daily anchor is locked at the day’s open or floats
- Whether commissions and fees count toward the day’s loss
Two firms can describe their rule with the same words and enforce it differently. The rulebook is the contract; a forum thread is not.
Building a live buffer to the daily floor
Knowing the rule is defense. Building a buffer is how you never test it:
- Set a personal stop above the real limit. If the firm’s floor is your hard wall, put your own soft wall meaningfully inside it and stop trading when you hit that. The gap absorbs slippage and the one trade you shouldn’t have taken.
- Track distance-to-floor live, not at day’s end. By the time a nightly statement tells you how close you came, the risk has already passed. A prop-firm drawdown calculator turns your rule into a concrete dollar floor before you place a trade.
- Let a hard limit enforce it. Willpower fails fastest exactly when you’re near the floor and tilting. This is where Shibiki pushes your personal daily stop down to the broker as a hard limit, so the account flattens at your line whether or not you’re watching — the rule holds when your discipline doesn’t.
The traders who last aren’t the ones who ride the daily limit like a wall. They’re the ones who set their own line well inside it and treat the firm’s number as a boundary they never actually reach.
