Monte Carlo Simulator
The Challenge Simulator replays trades you've already taken. This one looks forward: it plays your edge out across thousands of scenarios against a firm's real rules, and tells you how often that ends in a funded account — and which rule ends it when it doesn't.
Challenge rules
These are the headline rules of one representative plan — most firms run several. Check the numbers against the plan you're actually buying, and edit anything that differs.
We don't publish this per firm yet, so it stays your call — and it matters more than any other single rule. A trailing floor rises with your profits, so giving back a good run can end the challenge at an equity a static floor would have survived.
What one attempt costs. Used to work out what a funded account really costs once failed attempts are counted.
Target: $110,000 · Drawdown floor: $90,000
Extra rules (advanced)
Hitting the target early doesn't end the challenge — the account keeps trading, and keeps every way of failing, until this is met.
Largest share of total profit one day may contribute. 0 turns the rule off.
0 for no limit.
Your trading
Take these from your own journal, not from what you hope to do. Every number below is something a few months of records can tell you.
1.5 means a winner returns 1.5× what a loser costs.
Model detail (advanced)
How long you're willing to keep going. Runs that neither pass nor breach inside this budget are reported separately.
0 makes every winner identical — tidy, and not how trading works.
Spread and commission. 0.02 gives up 2% of the risked amount on every trade, win or lose.
Same inputs and same seed always give the same answer. Change it to draw a different set of scenarios.
The odds
Set the rules and your trading numbers, then run the simulation.
