For Traders: Arbitrage, HFT, grid, tick scalping, martingale
▶For Traders Forbidden Strategies Rule: 6 Bans That Void Accounts — 49s explainer, decoded by FundedWiki
Prohibited: all arbitrage (hedge/reverse/latency), HFT (<5s holds), grid trading, tick scalping, martingale/loss-recovery, one-sided betting, account rolling and overleveraging without a risk plan. Hedging is allowed within a single account only; cross-account hedging is prohibited. A 40% margin cap limits any single trade (or same-instrument/same-direction trades) to 40% of available margin.
The gotcha
The 40% margin rule caps how much of your buying power one trade can use — and grid trading is banned outright as market manipulation.
What happens if you break it
Breaching this voids the account outright — the evaluation or funded account is terminated and any unrealised profit is forfeited. It's the most severe class of breach.
