For traders on their own capital
How much capital does your strategy actually need?
The same seeded Monte Carlo engine prop traders use, pointed at your own rules instead of a firm’s: import your book, name your own limits, and watch which one breaks first. Nothing is uploaded — the simulation runs entirely in your browser.
What the free run answers
Three numbers, computed from the rules you set — not a recommendation, an inversion of your own inputs.
01
Capital before the floor
The account size your risk-per-trade and stated floor imply, before that floor closes the account.
02
Which limit breaks first
Where you set more than one rule, the run reports which of your own limits ends the path most often.
03
The risk band that matters
Swept across risk-per-trade levels, the run reports the band where your outcome moves the most.
When you want it stamped
The free run above is unlimited and permanent. The Personal Case File is the same engine, written down.
An attested, reproducible document of where your book stands against the rules you set: eight sections, the full sweep study, stamped — yours to keep.
Free calculators model a generic account from zero; this attests where YOUR book actually stands — reproducibly, from the same seed.
