News Trading Prop Firm Rules: Blackout Windows, Filters and Fills
Key takeaways
- No firm's current terms are quoted here. Restrictions of this kind are commonly structured around high impact releases, differ by account type and platform, and get revised, so read your own account's rules on the firm's site and save the answer with the date.
- A news restriction takes several shapes: a blackout window on new entries, a ban on holding through the release, a profit clause applied at review, and on some account types no stated restriction at all. Each demands different behaviour from your software.
- The risk is execution, not direction. Spreads widen, depth thins, and a stop can be filled far past where you placed it. You can be right about the move and still book the worst loss of your evaluation.
- Calendars are tiered. High impact releases such as CPI, NFP, FOMC and central bank rate decisions are the ones rules are commonly written around. Second-tier data moves price without usually being named in a rulebook.
- An EA news filter is only as good as five inputs: minutes before, minutes after, which currencies of the pair it watches, whether it closes open trades or only blocks new ones, and what it does when the calendar feed fails.
- On the futures side the exposure is contract-specific rather than currency-specific, and whether you may automate at all depends entirely on each firm's own policy. Confirm it with the firm before you connect anything.
What a news trading prop firm restriction actually is
Ask five funded traders what the news trading prop firm rule says and you will get five answers, each confident and each describing somebody else's account. There is no single rule. There is a family of restrictions, written differently by different firms, applied differently between the evaluation and funded stages, and revised without much ceremony. Rules of this kind are commonly structured around high impact economic releases, but the wording that binds you sits on your account type, and the only place to read it is the firm's own site.
It helps to know what the restriction is for. Firms are not trying to stop you being right about inflation. The restriction reads as an execution-risk control, aimed at the minutes when pricing gets unpredictable and fills stop being reliable. Read that way, the odd shapes make sense.
What follows is the mechanics: the shapes the restriction takes, why the danger lives in execution, and how a filter is configured. The shorter argument for stepping aside on purpose, rather than the rules that force you to, is in [trading the news on a funded account](/blog/trading-news-funded-account). Every figure below is an invented worked example.
The shapes a restriction takes
The same structures repeat across rulebooks. They are not interchangeable, and a filter built for one will walk you into another.
- The blackout window. New positions are commonly prohibited for a stated number of minutes before and after a listed release, say two minutes either side as an invented example. The trade inside that window is itself the breach, whether it won, lost or closed flat.
- The open-position restriction. Entries may be allowed at any time, but carrying a position through the release is not. This shape is easy to miss, because you do nothing wrong at entry and drift into the restricted moment. Software that only blocks new orders does not protect you here.
- The profit clause. The trade is not voided and nothing appears in the platform, but profit judged to come from a news spike can be discounted at review. This one surfaces weeks later at withdrawal, the worst time to find it.
- No stated restriction. Some account types are marketed as news-permitted and some firms restrict nothing. That is a commercial decision on their side, not an assurance that trading into a release is a good idea on yours. The execution arithmetic below ignores what the rulebook allows.
Why execution and not direction is the real risk
Direction is sometimes genuinely readable at a release. Experienced traders still sit it out because direction does not get paid. Fills get paid, and around a high impact number the fill is the part that stops behaving.
Four things happen at once. Spreads widen, sometimes sharply. Depth thins, because liquidity providers pull size rather than price it blind. Price gaps, moving through levels without trading at them. And your stop, an instruction to sell at market once a level trades, executes at the first price available on the far side of that gap. The stop did not fail. It did what a stop does in a market where the next price was somewhere else.
The invented worked example makes it concrete. You are on a $100,000 evaluation with a $5,000 daily loss line. You risk 0.5 percent, so $500, with a stop 20 pips away on a pair whose spread is normally 1 pip. The release lands, the spread opens to 12 pips, and your stop fills 45 pips from entry. That trade costs roughly $1,125 rather than $500. Two of those and nearly half the daily limit is gone, on a plan you thought was ten losing trades wide, without ever being wrong about direction.
A mandatory stop protects you less than it feels like it should here: it caps your intention, not your fill. The gap itself is covered in [slippage and execution on a prop firm EA](/blog/slippage-execution-prop-firm-ea), the requirement in [mandatory stop losses at prop firms](/blog/mandatory-stop-loss-prop-firms), and why one bad fill matters in [daily loss versus max drawdown](/blog/daily-loss-vs-max-drawdown).
How the release calendar is tiered
Economic calendars grade releases by expected impact, usually in three levels, and rulebooks are commonly written around the top one. Knowing which tier you are looking at separates a filter that pauses sensibly from one that pauses all day.
The high impact tier is small and predictable: inflation prints such as CPI, employment data such as the US non-farm payrolls, central bank rate decisions with their statements and press conferences, FOMC events and major GDP releases. These can move a major pair sharply in seconds, and these are what a restriction is commonly aimed at. The second tier moves price without usually being named: PMIs, retail sales, jobless claims, consumer sentiment. Treat those as a reason to size smaller, not a compliance question.
One detail decides whether a filter works. A release belongs to a currency, and a pair has two. An FOMC decision is a dollar event, so it hits EURUSD, GBPUSD and USDJPY alike. Gold is priced in dollars and reacts to the dollar calendar, which is why traders who filter one side of the pair get caught on metals.
How a news filter is configured in an EA, input by input
In MetaTrader a news filter is a handful of inputs, usually saved in the set file for your account. Every one changes behaviour materially, and the defaults were written for another rulebook.
- Minutes before and minutes after. Two numbers, not symmetric in practice: the pre-release window keeps you out of position, the post-release window waits for spreads to normalise. Set both wider than your firm's stated window. As an invented example, if the rule says two minutes either side, configure five and ten. A filter set exactly on the line can breach on a clock difference of seconds.
- Which currencies to watch. Either the filter reads both currencies of the traded pair, or it reads a list you supply. Watching one side only is a common misconfiguration, and on dollar-denominated instruments it fails silently.
- Impact threshold. High impact only, or high plus medium. High only is the common setting, since medium can pause a strategy for much of a normal week.
- Close open trades, or only block new entries. This input has to match the shape of your firm's rule. If the restriction is on holding through the release, blocking entries does nothing for the position you already hold. If it is only on new entries, closing everything hands back open profit.
- Feed source and fail behaviour. The filter reads a calendar from somewhere: the terminal's built-in one, or an external URL that must be whitelisted in the platform's options. If it cannot read the feed it either fails open, trading on unprotected, or fails closed. On a prop account you want fail closed.
The failure mode nobody tests: the feed goes quiet
A news filter is the only part of a trading system whose correct behaviour is invisible. When it works you see nothing happen, which is exactly what you see when it has stopped working. That is how a trader ends up learning the filter was broken from a rule-violation email.
The realistic ways it goes quiet: the URL was never whitelisted, so every request was refused from the first tick. The provider changed a format and the parser now returns an empty list, identical-looking to a calm week. Server time and the calendar's timezone disagree, so the window lands an hour off, protecting the wrong minutes. Or the terminal restarted and the EA reloaded without its permission.
The test takes ten minutes and is worth repeating monthly. Pick a known high impact release, run on a demo of the same server, and watch the log write the pause before it happens. If the EA prints its next scheduled event, confirm those timestamps match the calendar you read yourself. Which inputs live in which file is covered in [set files explained](/blog/setfiles-explained).
The same problem on the futures side
Futures traders meet this restriction wearing different clothes. The exposure is contract-specific rather than currency-specific: equity index contracts react to the US employment and inflation calendar and to the Federal Reserve, rate contracts react to rate decisions directly, and energy contracts have weekly inventory releases that behave like high impact events without always appearing on a macro calendar. A filter built around currency pairs does not map onto that, because there is no second currency to read.
Two mechanical differences matter. Futures trade in a central order book, so you see genuine depth thinning rather than a widening quoted spread, and a market order walks the book. On trailing-drawdown accounts the floor only ratchets upward, so the distance a bad fill costs you stays lost, turning one slippage event into a permanently tighter account.
On automation, the honest answer is that it depends on the firm. Whether an automated system is allowed at all on a futures evaluation or funded account, and under what conditions, is decided firm by firm and account type by account type. We will not tell you what any specific futures firm currently permits: that policy is theirs to state and it changes. Ask in writing and treat an ambiguous answer as a no.
Why this rule ends accounts, and the pre-release checklist
News restrictions do not end accounts because they are hard to understand. They end accounts because they are enforced at review, weeks after the trade, when the trader has forgotten the afternoon in question. A rule crossed in June is still crossed when a withdrawal is examined in August, and that timeline is in [how long the first payout takes](/blog/first-payout-timeline). The cheap version of this problem is a filter that pauses. The expensive version is an argument you cannot win.
Our disclosed position: PraxAI publishes this blog and sells trading software for MetaTrader 5, and it includes a news filter that pauses around high impact events, so it does not need willpower to sit out a release. A filter is not a strategy, and no configuration makes a pass certain. How to judge any tool in this category, ours included, is in our guide to the [best AI trading bots for prop firms](/blog/best-ai-trading-bot-prop-firms-2026).
Verify the rule in writing, set the filter wider than it, then run this routine before any heavy calendar day.
- Read tomorrow's calendar the night before, in your platform's server time rather than your local time, noting the high impact events for both currencies of every instrument you trade.
- Check what is already open going into each window, and decide the day before whether it closes, not ninety seconds before the number.
- Confirm your filter's window is wider than the firm's stated window, and that the stated window is the one written for your account type this month.
- Size smaller on a heavy calendar day. A position sized for a normal spread is oversized for a widened one, which is arithmetic rather than opinion.
- After the release, wait for the spread to return to normal before judging anything. The first minute of quotes is not a market you want to be measured on.
Frequently asked questions
What are the news trading prop firm rules?
There is no single rule. Restrictions of this kind are commonly structured in one of a few shapes: a blackout window prohibiting new positions for a stated number of minutes before and after a listed high impact release, a restriction on holding an existing position through the release, a clause that discounts profit attributed to a news spike when the account is reviewed, or no stated restriction at all on some account types. Which one applies differs by firm, by account type and by stage, and the terms get revised, so read the current rules on your firm's own site and keep a dated copy.
Can I trade news on a funded prop firm account?
Sometimes, and the answer is account-specific rather than industry-wide. Some account types are marketed as news-permitted and some firms restrict nothing, while others prohibit entries in a window around high impact releases or prohibit holding through them. Restrictions are also commonly tighter at the funded stage than during the evaluation, which catches traders who assume the rules they passed under carried over. Confirm it in writing for your exact account before you plan a strategy around it.
Which news events do prop firms usually restrict?
Rulebooks are commonly written around the high impact tier of an economic calendar: inflation prints such as CPI, employment data such as the US non-farm payrolls, central bank rate decisions with their statements and press conferences, FOMC events and major GDP releases. Second-tier data such as PMIs, retail sales and jobless claims moves price but is rarely named. Remember that a release belongs to a currency and a pair has two, so a dollar event affects every dollar pair and dollar-denominated instruments such as gold.
How do I set up a news filter on my EA?
Five inputs decide whether it works. Minutes before and minutes after the release, set wider than your firm's stated window rather than equal to it. Which currencies it watches, which should be both sides of the traded pair. The impact threshold, usually high impact only. Whether it closes open positions or only blocks new entries, which has to match the shape of your firm's rule. And what it does if the calendar feed fails, which on a prop account should be to stop trading rather than to keep going unprotected. Test it against a known release on a demo of the same server before it matters.
Is a news filter enough to keep me compliant?
It reduces the most obvious way this rule gets broken, which is a human deciding that one trade will be fine, but it is not a compliance guarantee. A filter can be configured to the wrong window, watch only one currency of the pair, apply the wrong timezone, or silently stop reading its calendar feed. It also does nothing about the execution risk on releases your firm does not restrict. Verify the rule yourself, set the filter wider than the rule, and check on a schedule that it is still reading its calendar.
