Your own futures account has a floor. The engine names which number hits first.
Numbers first: a self-funded book is the same object a prop evaluation is — starting capital, a drawdown floor, optional daily stop, horizon, trade statistics (widget fixes trades/day = 3 and cost = 0.05R). Answer first: PropSurvival already runs that object for firms; it also runs it for you — the Monte Carlo names which dial binds first.
The binding constraint on a self-funded account is still a number you typed — not a vibe, not a dashboard, not a guru. Set the nine dials. The Monte Carlo reports which one the paths hit first. Run it free at app?rules=personal&src=b2-self-funded.
Why this is the same arithmetic
A prop evaluation publishes a max loss, often a daily loss, a target, and a window. You already have analogues on your own futures account, even if you never wrote them down: the balance at which you stop, the day you walk away, the month you review. Write your own rulebook is the argument that those five rule-numbers are one mathematical object. This page is the futures-on-your-own-capital reading of that object.
The engine does not care whether a firm or you pulls the plug. It cares whether a path crossed the floor before the horizon. That is a simulation of your stated rules against your stated statistics, not a prediction of the market, and not a ranking of firms.
The nine dials, mapped
The live personal widget exposes nine fields. Two further assumptions are fixed in that widget and must not be silently promoted as if you set them: trades/day = 3, cost = 0.05R. The full desk at /app?rules=personal is the same engine at the product path count.
| Dial | On a self-funded futures book | Do not invent |
|---|---|---|
| Account size | The capital actually at risk — not buying power, not a firm’s advertised size. | A round number you wish you had. |
| Max drawdown % | The floor you will not cross. Static unless you have written a trailing rule. | A prop firm’s published cap copied without reading freeze language. |
| Horizon (days) | The window you will actually review against — 20, 30, 60. | An evaluation length from a sales page. |
| Daily loss stop % | A personal lockout: the day ends, the account continues. See personal daily loss. | Assuming a firm’s daily loss is also “just a lockout.” Often it is account-fail. |
| Profit goal % | Optional. Survival-only is a valid run. A self-funded book has no “pass certificate.” | A 6% or 8% target because a challenge used it. |
| Risk per trade % | Your size rule as a percent of the account you named above. | A hero size from someone else’s recap. |
| Win rate % | From your closed trades. How to extract them: nine dials from a broker book. | A round 55% because it “feels fair.” |
| Avg win (R) | Mean winning trade ÷ the amount you risked on it. | The best win, or a target R you do not actually take. |
| Avg loss (R) | Mean losing trade ÷ the amount you risked on it. Often near 1.0 if stops are honest. | Leaving losers uncounted because they were “not real trades.” |
Worked arithmetic — not a pass rate
Suppose $50,000 at risk, 10% max drawdown, 30 days, 1% risk per trade. Room is $5,000. Lives = 5,000 ÷ 500 = 10. That is a floor-and-size identity, the same risk-of-ruin lever the research pages already publish. It is not a forecast that you will survive, and it names no firm.
If the daily stop is 3% ($1,500) and it is a lockout, a path that hits it stops for the day and resumes tomorrow. If you model it as a firm-style account fail, you are answering a different question. The engine will happily answer either — you have to know which one you typed. That distinction is the whole of Personal daily loss vs a firm’s daily loss.
Trailing versus static on your capital is the same mechanic studied in static vs trailing drawdown. A trailing floor that ratchets with new highs is a tighter object than a static 10%. Do not paste a prop freeze-at-initial rule onto a self-funded book unless that is actually how you will trade.
What this page is not
- Not a crypto or spot-exchange product. Personal/independent is a persona, not a category pivot.
- Not a broker, NinjaTrader, or Tradovate integration. Mapping is numbers you type. APIs are out of scope.
- Not a recommendation to take or avoid a challenge. The wedge remains prop; this page is the independent reading of the same engine.
- Not a pass-rate for any named firm.
Working backwards: free path before you invent a pass rate for your own book.
Numbers first: room ÷ risk-per-trade is a floor-and-size identity (example: $50,000 × 10% ÷ 1% = 10 lives) — not a forecast. Answer first: run the nine dials on the free personal path; the engine names which constraint binds first. Trades stay on the device.
Simulated result from user-supplied inputs · not investment advice. PropSurvival is not affiliated with any firm, broker, or exchange. Trades never leave the device. Figures on this page are arithmetic identities or pointers to seeded studies; they are not a prediction of your next month.
