Definition
Gambling / all-in rule
A conduct clause banning bet-the-account behaviour: max-size punts, martingale, one-shot passes.
Firms want fundable risk management, not lottery tickets. Typical tells they police: full-margin single trades, no stop-loss punts at max size, or passing an evaluation with one oversized trade.
The clause is intentionally broad; if a trade only makes sense because it's someone else's money, it probably falls under it.
