News Trading Rules at Prop Firms: What's Restricted and Why

The direct answer: many prop firms restrict opening, closing or holding positions in a window around high-impact news events - commonly a few minutes either side of releases like Non-Farm Payrolls or central-bank decisions - and some apply these rules only on funded accounts, not evaluations. There is no industry standard. The restriction, the window length, and the affected event list all vary by firm and change frequently, so the only reliable source is the firm's current terms.

Why the rules exist

News spikes are where spread widening, slippage and gapping are at their worst. On a demo-fed evaluation, a stop order can fill at a fantasy price that would never print live - which means news scalpers can "pass" challenges with results the firm could never replicate with real capital. Firms restrict news trading to close that gap between simulated and real execution. If you want the mechanics, read our explainers on slippage and demo vs live trading.

The common rule types

• Blackout windows: no opening or closing trades within a set window around listed high-impact events. Windows of a few minutes each side are typical, but the exact figure differs by firm.
• No-new-positions rules: you may hold through the news, but not open fresh exposure inside the window.
• Hold-through bans: the opposite - positions must be flat before the release.
• Profit-invalidation rules: some firms allow the trade but void or claw back profits deemed to come from news spikes, especially on funded accounts.
• Evaluation vs funded asymmetry: a firm may allow news trading during the challenge but restrict it once you're funded. This asymmetry catches a lot of traders at exactly the moment the account starts to matter.

How the rules catch traders out - especially automated ones

A discretionary trader can glance at the calendar. An EA cannot, unless it was built to. The classic failure modes:

• The EA doesn't know the calendar exists. It opens a position 90 seconds before a rate decision because its signal fired. Rule breached, often without the trader noticing until the firm flags it.
• Pending orders trigger inside the window. Some firms count a pending order filling during the blackout as "opening a trade". Your stop entry from an hour ago becomes a violation.
• Time-zone and calendar-source mismatches. The firm judges the window by its own event list and clock, not yours. "I was three minutes outside the window by my calendar" is not a defence.
• Held positions with trailing stops can be closed by the broker inside the window - which under some rulebooks still counts as activity.

Practical checklist

1. Find the news rule in the firm's current terms - the actual document, dated. Confirm whether it applies to evaluations, funded accounts, or both.
2. Identify which calendar and which impact tier the firm uses to define "restricted events".
3. Confirm how pending orders and stop-loss executions inside the window are treated.
4. If you run an EA, make the restriction mechanical: a news filter, a time filter around known release slots, or simply flattening before the window. Our guide to designing prop-firm-safe EAs covers the options.
5. Re-check the rule every few weeks. Firms tighten and loosen news policies more often than almost any other rule.

A note on tooling (bias declared)

We build Nebula, a no-code EA builder with a prop-firm mode that bakes hard risk limits - daily loss and max drawdown - into every generated EA, so a news spike that goes against you hits a coded stop rather than your account's breach line. We're biased, but the principle is tool-agnostic: if a rule can end your account, it should live in the code. For a broader look at which firms welcome automation at all, see prop firms that allow EAs.
