Prop challenge simulator

Most people who fail a prop challenge do not fail on analysis — they fail on rules. The simulator applies those same rules to a practice account.

Which rules are simulated

Profit target, daily loss limit and maximum overall drawdown — the three that decide most FTMO-style challenges. Each is tracked live so you can see how close to a limit you are, rather than finding out after you have breached it.

Why practise before paying

Challenge fees are not small and are often paid more than once. Practising under the same constraints on real data, without real money, is the cheapest way to find out whether your style is even compatible with a daily drawdown cap.

The real lesson: position size

Most failures come from oversizing. With a daily drawdown cap, one oversized trade can end the whole challenge. The simulator is wired to the risk calculator so you practise this concretely.
