4D4Ds Trading Studio / Portfolio Sim
Options-based Monte Carlo · cash risk · first payout

Budget → Challenges → Phases → Payout

Uses the saved RR, R1/R2/R3 and risk decisions from your account's phase options. It simulates random trade outcomes rather than choosing future winning paths. No orders are placed.

Model scope: Risk amounts are used exactly or the trade is blocked. Minimum trading days after reaching a target are represented as administrative qualification assumptions (not invented W/L trades). Payout eligibility, subscriptions, trailing losses, firm allocation and checkout rules need separate verification.

1 · Investment & simulation inputs

Same-budget comparison allocates the entire budget separately to each firm. Split-budget mode divides one budget across the selected firms.

Each comparison row gets its own hypothetical copy of the selected budget. Results must not be added together.

2 · Prop-firm accounts

Saved profiles and phase-risk options are read from this browser's selected 4Ds user (—). Use Firms on the main site to adjust R1/R2/R3 and RR; the simulator doesn't create a second set of risk settings.

3 · Find Better Models

Automatically compare risk-sized models and trade-order rules using the same account, budget, win rate and RR. Candidates are shortlisted on one simulated random sample and retested using different random outcomes under the same assumptions. This is not historical validation or evidence of a new trading edge.

Select an account to calculate the maximum modeled starting risk.
Run a model search to compare alternatives.
Suggested models stay in Portfolio Sim until you explicitly send one to Firms.

Model assumptions & limits

Read before interpreting an ROI estimate

Evaluation challenges are purchased once at the start. No automatic replacements, retries, refund processing delays, repeated funded payouts or taxes are simulated. Topstep's subscription renewals, variant-specific activation rules, contract limits and full payout eligibility are not enforced. Its modeled initial payout is up to 50% of realized funded profit capped at $5,000; check the exact purchased path. FTMO/Hola pay a modeled split of funded profit after a planning target and waiting period, not a guaranteed withdrawal. Trailing drawdown is approximated for Topstep using end-of-day high-water marks and a zero-capped floor; intraday breaches and contract-size restrictions are not verified. Other firms' static initial floors are modeled where known. Fees, spread/slippage, evaluation activation delays, minimum qualifying trades and news restrictions may differ. If multiple accounts share a signal, outcomes may be correlated and diversification overstated. The model's risk-exhausted status does not mean an official failed-account breach.
