Understanding Prohibited Strategies
Prohibited strategies are specific trading approaches, techniques, or behaviours that a prop firm explicitly bans from its challenge and funded account programs. Violating these rules results in immediate account termination — no warnings, no second chances, and no refund of your challenge fee.
The most universally prohibited strategy is **high-frequency tick scalping** — opening and closing trades within seconds to exploit micro-price movements. Firms like FTMO, MyFundedFX, and Alpha Capital Group all ban this because it exploits latency rather than demonstrating genuine trading skill. The threshold typically sits around trades held for less than 30-60 seconds.
**Martingale and grid trading** without stop losses appear on most prohibited lists. The mathematical certainty of eventual account blow-up makes these incompatible with prop firm risk models. Even modified versions that "look like" martingale — progressively doubling position sizes after losses — trigger automated detection systems.
**Arbitrage strategies** including latency arbitrage, statistical arbitrage between correlated pairs, and cross-broker arbitrage are banned across virtually all firms. These exploit infrastructure inefficiencies rather than market analysis. Firms monitor for simultaneous opposing positions, unusually fast execution patterns, and correlation-based hedging.
**Account management services** where someone else trades your account violate every firm's terms. This includes Telegram signal services that execute trades automatically, copy trading from external sources, and having a friend or mentor place trades on your behalf. Firms use IP tracking, device fingerprinting, and trading pattern analysis to detect this.
Some firms have unique prohibitions: certain firms ban **overnight holding** entirely, others prohibit trading during specific news events (NFP, FOMC, ECB decisions), and some restrict the **maximum number of simultaneous open positions**. The5ers restricts leverage during high-impact news to 1:10, while Funded Trading Plus allows news trading freely.
Real-World Example
Using multiple accounts to hedge opposite positions is a prohibited strategy at most firms.
Why Prohibited Strategies Matters for Prop Traders
Understanding prohibited strategies isn't just about avoiding account termination — it's about understanding what prop firms actually value. Every prohibition tells you something about the firm's business model and what they consider "real" trading. Firms that ban scalping value sustained, analytical trading. Firms that allow news trading believe skilled traders can navigate volatility. Firms that prohibit EAs entirely want to see manual decision-making.
The consequences are severe and often permanent. Most firms maintain **internal blacklists** — get caught using prohibited strategies once, and you may be banned from purchasing future challenges. Some firms share violation data, meaning a ban at one firm could affect your standing at others. The financial loss extends beyond the challenge fee: you lose any profits earned, any funded account progress, and the time invested.
Before starting any challenge, read the **Terms of Service** completely — not just the marketing page. The marketing page might say "EAs allowed" but the ToS might specify "EAs allowed except those using tick data, latency exploitation, or martingale logic." These nuances matter enormously.
6 Practical Tips for Prohibited Strategies
Create a personal "prohibited strategies checklist" for each firm before starting — screenshot the relevant ToS sections and keep them visible during trading
If you use an EA, test it against the firm's specific rules: check average trade duration, whether it doubles down after losses, and whether it opens correlated positions simultaneously
Contact support BEFORE starting if your strategy is borderline — get written confirmation that your approach is acceptable and save the conversation
Avoid holding trades for less than 60 seconds even if the firm doesn't explicitly ban it — extremely short trades attract scrutiny from automated monitoring systems
Never use the same EA with identical parameters across multiple prop firm accounts simultaneously — this triggers copy trading detection even if you own all accounts
If a strategy involves opening opposing positions on correlated pairs (e.g., long EURUSD and short GBPUSD), check if the firm considers this hedging or arbitrage
Pro Tip
The safest approach is to trade your prop firm account exactly as you'd trade a personal funded account — with genuine analysis, reasonable position sizes, and trades held long enough to reflect market conviction. If your strategy requires exploiting execution speed or mathematical progression rather than market analysis, it probably won't survive a prop firm's compliance review.
Common Mistakes to Avoid
Assuming "EAs allowed" means ALL EAs are allowed — most firms restrict specific EA behaviours like tick scalping, martingale logic, or latency exploitation
Using a strategy that worked on another firm's challenge without checking if the new firm has different prohibited strategy lists
Running the same strategy across 5+ prop firm accounts simultaneously — even legitimate strategies trigger copy trading detection at scale
Not reading the Terms of Service beyond the marketing page — the actual legal document often contains restrictions not mentioned on the sales page
Believing that manual execution of a prohibited strategy makes it acceptable — manually executing martingale sizing is still martingale
