Are there prohibited trading strategies?

Yes. Zibrock supports genuine, independent traders, but any style designed to game or abuse our system and software is strictly banned and is a serious breach of our Terms. Prohibited practices include: arbitrage trading; high-frequency trading (HFT); news bracketing (opposite pending orders around high-impact news); exploiting system errors; copy trading; sudden trade-size outliers (gambling-style lot spikes); one-sided bets; rollover scalping; third-party robots and EAs without your own source code or company approval; tick scalping; hedge/reverse arbitrage; account sharing or selling; AI or mass-data tools that manipulate the market or give an unfair edge; bypassing sanctions; trading on behalf of others; intentional IP-rule breaches; and martingale. The 70% rule also applies: a single trade or one-directional trades cannot make up more than 70% of the total profit target.
