Lux Trading Firm's 1-Step Evaluation (flagship evaluation challenge; distinct from Lux's separate 'Instant Funding'/INSTA no-evaluation product and its separate 'Prediction Markets' product, neither modelled here) enforces a consistency requirement at every account size PropSurvival's corpus carries for this program (100k, 400k, 1000k): no single trade may risk more than 5% of Remaining Risk Capital (current balance minus the drawdown limit), enforced at every trade, and the trade's position size itself is capped to keep exposure inside the limit, rather than a pass or payout withheld after the fact.
| Phase | Limit | Enforced at | Effect |
|---|---|---|---|
| Evaluation (Stage 1 / "Demo") | 5% | every trade | the trade's position size itself is capped to keep exposure inside the limit, rather than a pass or payout withheld after the fact |
