Your rule workspace

Inspect a fictional account path under two loss models. Keep inputs, rule versions and sources locally.

The reading crab explains the decisive floor on request. You control each step; the rules do not forecast success.

Fictional model · methodology account-replay.v1 · as of 2026-11-04. The higher active floor decides. Equality touches the limit. A daily pause discards later observations of that day; account termination ends that model's replay.

Chronological account path

Absolute values in one account currency. Each day opens from the last observed state. Account changes or withdrawals require a new replay.

Private titles and notes are excluded from this dossier.

Note: A calculation aid using your own assumptions. Not investment advice and not a forecast of success: simulated profits are not income, and most challenges are not passed. The firm's rules that actually apply to your account govern.

Risk: know this before you buy

Prop challenges are paid evaluation programmes, mostly on simulated accounts. Most participants do not pass: in an analysis by FPFX Tech covering about 100,000 traders at 10 firms, about 14% of traders passed and about 7% received a payout (Finance Magnates, 18 Sep 2024; methodology not disclosed, FPFX sells software to prop firms).

The firms are generally not supervised by FINMA, BaFin, the FMA or the FCA. There is no investor or deposit protection and no ombudsman. The Financial Commission is a private dispute-resolution body, not a regulator.

Firms can change their rules unilaterally and are often the counterparty themselves. Austria's FMA compares paid challenges to the relationship between a player and a casino.

For readers in Austria: the FMA raises the question of a licensable activity for participants themselves too (FMA, "Was ist Prop Trading?", 8 May 2026).

How this is calculated

Observations, not invented fills

Equity includes open profit and loss. The order of observations matters. The replay does not interpolate unknown prices or fills.
