While effective in institutional settings, it overloads trading servers and disrupts liquidity flow in simulated environments. * **Why it's banned:** The strategy creates artificial volatility, strains platform infrastructure, and does not align with sustainable trading practices. ### Other Prohibited Strategies * **Account Sharing:** Using multiple identities to own more than one account per cohort * **Multi-Account Hedging** — Owning two or more accounts and placing opposing trades across them (e.g., buying EUR/USD in one account while selling it in another) as a way to bypass challenge rules and manipulate pass rates. * **Account Sharing or Passing Programs -** Allowing others to trade on your behalf or participating in programs that offer to pass the evaluation for you * **Use of Masked Expert Advisors (EAs) -** Using commercially available EAs without proper disclosure or attempting to hide their usage is forbidden. * **Copy Trading and Signal Services -** Relying on third-party signal services or copying trades from other traders undermines the evaluation of individual trading skills and is not permitted. Multi-account hedging distorts real trading evaluation and goes against the spirit of skill-based trading. Any accounts detected engaging in this practice will be subject to immediate disqualification. By enforcing these rules, we ensure a level playing field where traders can succeed based on skill, strategy, and risk management—not loopholes or exploitative tactics. --- # Agent Instructions This documentation is published with GitBook.
