How to secure your risk against a prop firm

1

1. Know your daily limit

Every prop firm sets a maximum loss per day (often 5% of capital). Breaching it, even by one dollar, fails the challenge. It's the red line you must never cross.

2. Compute your worst day

Multiply your risk per trade by the number of trades you take on a bad day. If they all hit their stop, that's your maximum daily loss. It must stay below the limit.

3. Adjust before you trade

If your worst day exceeds the limit, reduce your risk per trade or your number of trades. The tool gives you the maximum risk compatible with your limit.

Worst day = risk per trade × number of trades. As long as it stays below your daily limit, your plan is compatible. Otherwise, you risk burning your challenge in a single bad session.

Frequently asked questions

How do I avoid breaching a prop firm's daily limit?

Make sure your worst day (risk per trade × number of trades) stays below your limit. With a 5% limit and 1% risk per trade, you can take up to 4 stops before nearing the limit. Reduce risk or stop early if you trade more often.

What risk per trade for a prop firm?

Often 0.5 to 1% of capital. Lower than the daily limit divided by the number of trades you take. The goal isn't to win fast, but to never touch the limit that would fail you.

Is the limit based on starting or current capital?

It depends on the prop firm: some compute it on the start-of-day balance, others on initial capital. Always check your firm's exact rules, as it changes the amount you must not exceed.

Is this calculator free?

Yes, fully free and no sign-up. The Tradoshi app goes further by tracking your prop firm drawdown in real time, aligned with your firm's rules, with alerts before you near the limit.
