For Traders: Arbitrage, HFT, grid, tick scalping, martingale

ForbiddenVoids accountHidden ruleVerifiedUpdated Jun 5, 2026

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.
