Every prop firm has a list of prohibited trading strategies. Use one and your account disappears — regardless of whether you're profitable. Unlike market losses, rule violations aren't appealable. Understanding every banned strategy is as important as understanding your entry criteria.
Category 1: Arbitrage Strategies
Latency arbitrage exploits tiny price differences between a prop firm's quote feed and faster external price feeds. Statistical arbitrage uses mathematical relationships between correlated instruments to lock in risk-free profits. Both are universally banned because they don't test trading skill — they test technology speed. Nearly every prop firm explicitly prohibits all forms of arbitrage.
Category 2: Martingale and Grid Systems
Martingale strategies double position size after every loss, betting that eventual wins will recover all losses. Grid trading opens buy and sell orders at regular intervals creating a grid of positions. Both create unlimited theoretical risk — a single extended trend can produce losses that exceed any drawdown limit. Most firms ban or strongly restrict these.
Martingale ban reason: on a $100K account with 10% max drawdown, a martingale strategy that doubles from $1K can blow the account in 3 consecutive losses: $1K → $2K → $4K → $8K = $15K lost. Four losses = $31K. Five = $63K. Account gone before the 'recovery' trade.
Category 3: Tick Scalping / High-Frequency
Holding trades for less than 30 seconds (sometimes 1–2 minutes) is restricted or banned at many firms. The reason: tick-level scalping exploits spread and execution model inefficiencies in simulated prop environments rather than trading actual market structure. Firms ban it to prevent exploitation of their infrastructure.
Category 4: Copy Trading and Trade Copiers
Using a trade copier to mirror signals from another account into your prop firm account is banned universally. The challenge is designed to evaluate your trading, not someone else's. Some firms also ban using third-party signal services, though this is harder to detect and less consistently enforced.
Category 5: Account Passing / Sharing Services
Paying someone else to pass your challenge for you ('account passing services') is explicitly against terms at every prop firm. The funded account is tied to your identity (KYC). If the firm determines someone else managed the challenge phase and you're trading the funded account, both accounts will be terminated.
Category 6: Hedging Between Accounts at the Same Firm
Opening opposing positions on correlated instruments across two accounts at the same firm to lock in a 'guaranteed' payout is a form of exploitation that virtually all firms prohibit. Example: long EUR/USD on Account A and short EUR/USD on Account B at the same firm ensures one account passes while the other is hedged.
- Same-firm two-account hedging: banned at all major firms
- Cross-firm hedging with identical instruments: technically allowed but ethically grey
- Hedging within a single account (standard hedge): allowed at some firms, banned at others — check T&C
Category 7: Automated Bot Restrictions
Not all EAs are banned, but certain types are. High-frequency EAs that trade dozens of times per hour, news spike EAs that enter in the 1-second after a release, and grid/martingale EAs are banned at most firms. Manual-trading-style EAs that manage entries and exits within normal time frames are generally permitted. Always disclose EA use to your firm before the challenge starts.
Category 8: Reverse Challenge Exploitation
Some firms have been exploited by traders who intentionally fail the challenge in Phase 1 while hedging gains in Phase 2, then reversing. This 'challenge exploit' typically involves starting extremely risky and hoping for favorable variance to hit the target while keeping a hedge. Firms monitor for this pattern and will void accounts where it's detected.
The golden rule: if your strategy's edge depends on the firm's pricing or execution model rather than the market, it will be banned. Trade market structure. That's all that's permitted.
