The weekend loss rule is a trade-management rule that closes any position not showing a profit by Friday's close, rather than carrying it through the market's two-day shutdown. Professional trader Peter Brandt calls it the "Weekend Loss Rule." Gary Glover (AR 259215), Authorised Representative of Novus Capital Limited (AFSL 238 168), who reviews ASX momentum stocks in a recorded weekly session with Finer Market Points, raised the rule during the 24 July 2026 session — in a market Christopher Hall's FMP data showed offering roughly a 3% chance that any given ASX stock rises 10% or more over the following month. This article explains what the rule is, the gap-risk logic beneath it, where it came from, and how ASX momentum traders adapt it.
What Is the Weekend Loss Rule in Trading?
The weekend loss rule is simple to state: if an open position is not in profit by the Friday close, the trader exits it before the weekend. It is a time-based exit — a "time stop" — rather than a price-based one. A conventional stop-loss asks how far a trade can move against the account; the weekend loss rule asks how long a trade is given to start working before the market shuts for two days.
The rule surfaced during Gary Glover's 24 July 2026 session with Finer Market Points, where he described it from the writing of veteran professional trader Peter Brandt:
"If the position wasn't in profit by Friday, they cut it... if it wasn't in profit by Friday, end of day, they'd just cut it, get rid of it." — Gary Glover, Finer Market Points session, 24 July 2026
Gary Glover's anecdotal observation, developed across his trading career, is that a strong momentum trade tends to work reasonably quickly — so a position sitting flat or underwater by week's end has, in his practitioner view, already failed to confirm the thesis. This is a practitioner observation, not a formal study. The rule turns that intuition into a mechanical exit that removes the decision from the heat of a Monday open.
Why Do Traders Cut Positions That Aren't in Profit by Friday?
The core reason is weekend gap risk — the two days when a position cannot be managed but the news does not stop. Markets close on Friday afternoon; company announcements, offshore moves, commodity prints and geopolitical events keep arriving across Saturday and Sunday. When trading resumes on Monday, price can gap straight through a stop-loss level, turning a small manageable loss into a larger one the trader never had the chance to cap.
Peter Brandt frames the rule around two benefits: risk and peace of mind. Carrying an underwater position across a weekend accepts roughly 48 to 72 hours of un-hedgeable gap exposure that an overnight hold on a weekday does not. Brandt has stated that, early in his career, trades held with a Friday loss cost him more than any other type of trade — the observation that hardened the rule into a habit.
The second benefit is psychological. A trader carrying a loser into Saturday spends the weekend managing anxiety rather than resting; a flat book of only-working positions is easier to hold with discipline. For momentum traders, there is a third, capital-preservation angle: a trade that has not moved by Friday is occupying capital and risk budget that a genuinely working setup could use instead. Cutting the dead trade is as much about freeing the account as avoiding the gap. This capital-preservation logic connects directly to the hidden cost that difficult ASX conditions impose on disciplined traders.
Where Did the Weekend Loss Rule Come From — Donchian and Peter Brandt?
The weekend rule is older than any single trader, tracing back to Richard Donchian, the pioneer of systematic trend following. Donchian's original "Weekend Rule" was a trend-entry signal — act on a market that closes strongly into a Friday — and Peter Brandt has credited that lineage directly, describing the modern loss-management version as a "Donchian/Brandt Weekend Rule."
Brandt frames the rule as risk-first — a discipline built less on being right often than on controlling the cost of being wrong. Reducing exposure ahead of a period when a position cannot be managed is a defensive rule, not a predictive one — it makes no claim about which way Monday opens, only about not being trapped when it does.
Applied to Australian markets, the lineage matters because the ASX carries its own weekend information gap: many ASX-listed miners and explorers are exposed to commodity prices and offshore catalysts that move while the local market is closed. The named-authority chain — from Richard Donchian to Peter Brandt — is what separates the weekend loss rule from generic "don't hold over the weekend" advice.

Why Does the Weekend Loss Rule Matter More in a Difficult ASX Market?
A time-based exit earns its keep precisely when setups stop following through — the condition FMP data flagged in late July 2026. Christopher Hall's FMP Momentum Profile readings at the 24 July 2026 session described an unusually hard tape for momentum trading. The three readings that framed the session:
FMP session reading (week of 24 July 2026) | Value |
ASX momentum edge vs a random-entry baseline | ~6% better than random |
Difficulty vs a normal market | ~21% harder than normal |
Chance a given ASX stock rises 10%+ over the next month | ~3% |
These are session observations drawn from Finer Market Points' proprietary momentum data for that week — not a forecast, and scoped to that period. In a market with roughly a 3% monthly probability of a 10% move in any single name, a large share of new positions will simply not work — they trigger, stall, and give the entry back. A flat-by-Friday exit is a fast, unemotional way to clear those stalled trades before the weekend adds gap risk on top of an already low hit-rate.
This is the same reasoning behind Gary Glover's two adjustments for a hard-penny market — trade lighter and tighter when moves stop following through — and it complements the observation that a small number of 12–14 weeks each year generate the bulk of annual momentum gains. Preserving capital through the difficult stretch is what leaves a trader positioned for the productive one.
Remember that past performance is no guarantee of future results, and all trading involves risk.
How Do ASX Momentum Traders Adapt the Rule?
Momentum traders tend to treat "not in profit by Friday" as a confirmation failure — the same discipline that says trade the leader and cut the laggard. Gary observed across the 24 July session that a genuine momentum leader usually moves in the trader's favour without much delay, while a position that drifts sideways or fills red is behaving like a laggard. That distinction is the heart of why leaders run and laggards keep lagging — a trade that will not get going is often telling the trader it is not the leader.
Three practical adaptations recur among momentum traders:
Pairing a fast cut with letting winners run. A time-stop that removes non-performers quickly is the defensive half of an asymmetric approach — small, frequent exits on trades that stall, held against a few large gains on the trades that work.
Using the rule alongside moving-average exits, not instead of them. The weekend loss rule handles trades that have not yet worked; a 10-day and 20-day moving-average framework manages trades that are working, and the 50-day moving average governs the larger trend.
Watching the tape for weekend catalyst risk. Heavy-volume down days into a Friday are exactly the distribution signals a trader does not want to hold a losing position against over two dark days.
None of this is a mechanical guarantee. It is a framework for deciding which trades have earned the right to occupy capital into the weekend and which have not.
Is the Weekend Loss Rule Right for Every Trader?
No single rule fits every timeframe, and the weekend loss rule is a heuristic, not a law. A short-term swing trader running tight, fast setups has the most to gain from it; a longer-horizon position trader or an investor building a multi-month thesis may reasonably give a trade more than five sessions to develop, managing weekend risk through position size instead. The rule also cuts both ways — a mechanical Friday exit will sometimes close a trade the day before it would have worked, which is the cost of removing weekend gap risk.
That trade-off is the point rather than a flaw. The weekend loss rule accepts a slightly lower win rate on individual trades in exchange for capping the tail risk of an unmanaged weekend gap and freeing capital in a low-hit-rate market. Traders weighing whether to adopt it are weighing their own timeframe, position sizing and temperament — the kind of decision that belongs in a documented trading system with a tested expected value, not an ad-hoc call at 3pm on a Friday.

Frequently Asked Questions
What is the weekend rule in trading?
The weekend rule, in its loss-management form, is the practice of closing any open trade that is not in profit by the Friday close rather than carrying it through the weekend. It treats the two-day market shutdown as a period of un-manageable gap risk and exits trades that have not yet confirmed. Professional trader Peter Brandt is its best-known modern advocate, and the concept traces back to trend-following pioneer Richard Donchian.
Did Peter Brandt invent the weekend loss rule?
No. Peter Brandt is closely associated with the modern loss-management version and refers to it as a "Donchian/Brandt Weekend Rule," but the original weekend rule came from Richard Donchian, a pioneer of systematic trend following. Donchian's version was primarily a trend-entry signal; the exit-focused application — cutting trades not in profit by Friday — is the form most traders reference today.
Should a trader hold a losing position over the weekend?
Traders who follow the weekend loss rule do not. Their reasoning is that a weekend adds roughly 48 to 72 hours during which a position cannot be managed, while company news, commodity moves and offshore events continue. A Monday gap can move price straight through a stop level. Whether to apply the rule depends on a trader's timeframe and position sizing — it suits short-term traders more than long-horizon investors.
What is the difference between a weekend loss rule and a stop-loss?
A stop-loss is a price-based exit: it closes a trade when price falls to a set level, capping how far a position can move against the account. A weekend loss rule is a time-based exit: it closes a trade that has not become profitable within a set time — by Friday — regardless of where price sits. Many traders use both together, one governing distance and the other governing time.
Why is weekend gap risk higher than an overnight hold?
An overnight hold on a weekday spans a single non-trading period before the market reopens and the position can be managed again. A weekend spans two, and news flow does not pause across Saturday and Sunday. The longer the market is closed, the more information can accumulate and the larger the potential opening gap — a gap that can skip past a resting stop-loss order before it executes.
Does the weekend loss rule work in a sideways or choppy market?
The rule is most relevant in difficult, choppy conditions, because that is when a high share of setups trigger and then stall. Finer Market Points data at the 24 July 2026 session described a market roughly 21% harder than normal to trade, with about a 3% monthly chance of a 10% move in any given ASX stock. In that environment, quickly clearing trades that have not worked preserves capital and risk budget — though no rule removes the underlying difficulty of the market.
Where does the weekend loss rule come from?
The modern loss-management form is most associated with professional trader Peter Brandt, who calls it the "Weekend Loss Rule." Brandt credits the underlying idea to Richard Donchian, a pioneer of systematic trend following, and refers to a "Donchian/Brandt Weekend Rule." Gary Glover raised the rule during the 24 July 2026 Finer Market Points session as a discipline he had read in Peter Brandt's writing — cutting any position not in profit by the Friday close to avoid weekend gap risk.
