STRATEGY RESEARCH. BEFORE THE RISK.

Test your edge.
Before the
challenge fee.

A profitable journal is a starting point. Replay the trades, pressure-test the rules, and see what survives after fees—before committing to another paid prop challenge.

THE PART A PROFIT CURVE MISSES

A good return can still
be a failed challenge.

The right question is bigger than “did it make money?”
Would it survive the rules—and would anything reach your pocket?

01

A profitable finish. A risk breach on the way.

Daily resets, open-position losses and maximum drawdown can change the outcome before the final PnL is known.

02

A target reached. A stage still incomplete.

Qualifying days, consistency conditions and progression rules matter alongside the profit target.

03

Paper profit. Personal cash still negative.

Challenge purchases, payout eligibility and the trader’s split tell a different story from trading PnL alone.

FROM A JOURNAL TO AN ANSWER

Less guesswork.
More evidence.

Follow your strategy through the full attempt. Keep the baseline clear, then ask what would change with different sizing and assumptions.

  1. 01 / SELECT

    Start with your journal.

    Choose a strategy and its timeframe. Review the recorded entries and exits behind the performance.

  2. 02 / REPLAY

    Put the rules around it.

    Select a supported challenge, model the fee and follow the strategy through attempts, stages and simulated payouts.

  3. 03 / IMPROVE

    Find what needs to change.

    Open a challenge’s calendar, inspect the failure day, and compare sizing scenarios separately from the original result.

The useful question

What happened
between entry and exit?

Open the trade. Review the evidence.

Daily risk, maximum loss and stage targets belong in the same review. Demo values are not a live trading record.

MAKE THE ECONOMICS VISIBLE

The goal is a better decision.
Not another retry fee.

Use a full replay to examine whether a strategy’s modeled payouts justify its challenge purchases. A smaller position size can change the path; the ledger shows the cost of finding out.

Bring your AI into the research loop.

Connect an AI platform through OAuth MCP to inspect results, adjust journal parameters and evaluate scenarios. Keep each saved result and its assumptions reviewable.

TRY THE MATHIllustrative assumptions

Not a forecast or a firm’s advertised pricing. Refunds and additional costs are excluded from this simple example. Full replays apply the selected fee and payout assumptions.

ONE STRATEGY. DIFFERENT RULEBOOKS.

Find the challenge
that fits your process.

Start with the profiles available today. Our roadmap expands the same trade-by-trade review across major prop firms, with each firm’s own targets, loss limits, stage requirements and payout rules.

PLANNED

FundedTrader

Dedicated rule profiles and a comparable strategy replay.

Not yet available

Need different assumptions today? Custom firm replay settings are available for manually configured rules.

More major firms are planned. Named future profiles are not yet implemented; a custom replay is not a verified substitute for a firm’s complete rulebook.

BEFORE YOU BEGIN

Clear expectations.
Better research.

Inspect the path, the assumptions and the cost—not just the headline return.

Does PropSimulator guarantee a pass or a payout?

No. It models historical trades against selected rules and assumptions. A numerical target is not a funding approval, and a simulated payout is not money received from a prop firm.

What can I validate today?

Replay existing journals against the available HyroTrader presets or custom firm assumptions. Review challenge attempts, daily and total loss limits, stage targets, modeled costs, payout events, personal cash and entry/exit chart evidence.

Can I compare different position sizes?

Yes. Save what-if scenarios with reduced sizing and reductions after wins or losses. Scenarios remain separate from baseline results so you can see which assumptions produced each outcome.

How should I interpret the historical results?

Results depend on the recorded trades, cached market coverage and selected rules. Missing price evidence is identified rather than invented. Historical simulations can differ from future execution, liquidity, slippage and a firm’s own assessment.

Are Topstep, FundedTrader and FundedNext supported?

They are on the roadmap. Firm-specific profiles and cross-firm comparisons will be added as their rules are researched and implemented. The availability labels above distinguish current features from planned work.

Does this connect to my AI assistant?

Yes. The research MCP server uses OAuth and supports journal analysis, strategy parameter editing and scenario evaluation. It does not grant live exchange trading or withdrawal permissions.
