Prohibited Strategies
Breaching any rule below may result in a warning, profit adjustment, account review, or termination.
Market manipulation and deception: No fraudulent conduct, price manipulation, spoofing, or anything designed to distort the market or create false trading conditions.
Microscalping: Trades closed within 2 minutes of opening. Not a breach in itself, but any profit from them is deducted from your account. (Not applicable to Flex Challenge and Flex Funded Accounts)
Exploiting pricing or feed errors: No profiting from mispriced quotes, lagging updates, feed latency, or data discrepancies. Using external or slower price sources (broker accounts, third-party feeds) for an edge is also prohibited.
High-frequency and algorithmic exploitation: No high-frequency systems, AI tools, tick scalping, or bulk order-entry that exploit execution speed or system inefficiencies rather than trade real conditions.
Arbitrage: No arbitrage of any kind — latency, hedge, reverse, or rollover/scalping — as it exploits structural inefficiencies rather than genuine speculation.
Coordinated trading: No coordinating trades to influence outcomes, whether across your own accounts or with other clients. This includes opposing or hedged positions across accounts, group trading, trade signaling, or sharing environments, devices, VPS instances, or IPs to enable linked trading.
Copying other users' trades: Copying your own trades across your own accounts (GFF or elsewhere) is allowed. Copying other users' trades or signals — manually, via copy/mirror services, or EAs — is not. Someone else may be copying the same source, creating linked positions across unrelated accounts; where detected, all accounts and users involved may be suspended.
Gap trading: No trading to capture price gaps from market closures and re-openings.
Artificial trades to meet requirements: No token, undersized, or manipulated trades used to fake active trading days or bypass risk controls.
Volume inflation: No abnormally high trade counts or oversized positions on negligible price movement to inflate profit.
Non-viable strategies: No strategy that could not realistically be executed on a live exchange.
Responsible risk and position sizing: No staking a disproportionate share of equity on a single position, one-sided all-in bets, or account rolling. Keep sizing consistent with your strategy and balance — erratic, unexplained jumps (e.g., one contract then ten) may be treated as gambling rather than disciplined trading.
