Hidden Prop Firm Rules That Void Payouts

Consistency rules: the most common payout-voider. Firms cap your best day as a percentage of total profit — 20% is aggressive, 40% is standard, 50% is generous. If you make $10k profit and $5k came from one day, some firms will pay you only $4k (2x the biggest day, or similar). Check this before you buy.

Stop-loss requirements: a subset of firms void trades held without a stop-loss on the platform. Check whether mental stops count.

News blackout windows: even firms that 'allow news trading' often restrict positions 2 minutes before to 2 minutes after tier-1 events (NFP, CPI, FOMC). Trades opened inside the window are voided; trades opened before and held through are usually fine.

Prohibited strategy clauses: arbitrage, latency exploitation, grid trading, tick-scalping, and 'reverse gambling' are commonly banned. Wording varies — read it.

Consecutive-day rules: some futures firms require you to trade every payout period; skipping days can reset your payout eligibility.

Payout-day account freezes: several firms freeze new trades on the day you request a payout. Not a rule violation, but a scheduling gotcha.

The universal advice: read the trading policy PDF, not the marketing site. Every reputable firm publishes one. If a firm doesn't publish rules in a single downloadable document, that itself is a red flag.
