What Is a Daily Drawdown Limit? Rules and Reset Times

A daily drawdown limit caps how much an account may lose within a single trading day, measured from a reference set at the start of that day. It is the standard risk control in proprietary trading firm agreements, enforced automatically: breach it by a cent and the account is failed regardless of the overall result. Unlike ordinary drawdown, it resets daily and is judged intraday.

How it works

Reference    = balance or equity captured at the daily reset
Daily loss   = Reference − Current equity
Breach when    Daily loss ≥ Limit % × Reference

Three parameters decide what the rule actually means, and they differ between firms.

Balance-based or equity-based. A balance-based limit counts closed trades only. An equity-based limit counts floating losses too, so an unrealised loss can breach the rule before it is realised — or before it recovers. Most agreements are equity-based, so the check runs on every tick.

Which reference. Some firms take the balance at the reset, some the equity, some the higher of the two. That third variant is strictest: unrealised profit raises the reference, so an account opening the day on a floating winner gets no extra room, only a higher bar to fall from.

When the day starts. The reset happens at a fixed time on the firm's server, typically 00:00 platform time or 17:00 New York — not your local midnight. A position held across it changes which day's budget it consumes, and a loss taken at 23:55 platform time comes from a budget that refills five minutes later.

A worked case: a $100,000 account, 5% equity-based limit, balance reference. The floor is $95,000 equity. Closed losses of $3,000 plus a floating loss of $2,100 puts equity at $94,900 — breached, even though only $3,000 was realised, and even if that open position closes at break-even an hour later.

It runs in parallel with the overall limit, measured against the initial balance or a trailing high-water mark, which never resets. The daily one is tighter and breached far more often.

Why it matters

The daily limit changes what a strategy is allowed to be, not just how large it may trade. Any system that recovers within the same day — averaging down, grid, holding through an adverse move — is incompatible with an equity-based daily rule, however well it performs over a month.

It also blocks the worst reflex in trading: doubling size to recover a loss on the day it happened. Whether a firm imposes the rule or a trader adopts it, that is most of its value — a second floor alongside margin level, and on a leveraged account usually the one reached first.

What the data shows

Across the public accounts on ShowMyTrades with trading history (August 2026), the median trade length is 2.4 hours and the median account has 171 closed trades. These are accounts published here, not traders in general.

A 2.4-hour median means the typical position opens and closes inside one session. For accounts trading that way the daily limit, not the overall one, is the binding constraint: nearly all the risk is expressed and resolved inside a single reset window.

The depth figures set the scale: median deepest drawdown 9.7%, with 38.5% under 5% and 38.2% past 20%. A 5% daily rule is calibrated to be uncomfortable, not generous.

Automation matters too: median autotrading share is 99% and 53.9% of accounts run above 90% automated. An Expert Advisor has no concept of the firm's reset time unless it was coded with one, which is why the reference-and-reset detail is not trivia.

Where you see it on ShowMyTrades

ShowMyTrades does not set or enforce prop firm rules. It provides the day-level record needed to check whether one was respected.

• The Monthly Returns module has a Calendar view alongside Table, Chart and Summary. It shows every day's result with week summaries beside it, so a single bad day stays visible instead of averaging into its month.
• Avg Daily %, the third row of the Account Stats panel, under Gain and Abs. Gain, gives the typical day an outlier is judged against.
• The Drawdown view in the charts viewer plots daily drawdown as bars over the account's life; days that approached a limit read as spikes.
• The trades table, with Duration, Profit (Gross), Swap and Commission per trade, is how a single day's loss is reconstructed.

Note the measurement gap: the calendar is built from closed results, while an equity-based rule watches floating equity tick by tick. A day that reads as a small loss here may still have breached one intraday.

Common misunderstandings

• "I closed only 4% down, so a 5% rule held." Under an equity-based limit, floating losses count the moment they exist. What you closed is not what was measured.
• "The day resets at midnight." It resets at the firm's server time. Traders in other time zones routinely book a loss on what they believe is the next day.
• "The overall limit is the real risk." The daily one is smaller and tested every session. It ends most accounts.
• "Hedging pauses the loss." Both legs still float, both carry spread and swap, and combined equity is what the rule reads.
