About & methodology

PropRuleGuard turns prop firm rules into calculators. Every rule value comes from the firm's own website or help center, and each firm page links to the exact pages and quotes we used, with the date we last checked them.

We watch the firms' rule pages for changes every day. When a page changes, the new values are extracted and checked automatically. If the checks pass, the change goes live straight away, marked as auto-updated, and we can reverse it within 18 hours; anything unusual waits for a person to approve it. A few firms block automated checks, so their pages are checked by hand, and their firm pages say so.

The free calculators run entirely in your browser: the days you type and the statements you import are not uploaded. If you create an account to track your trading accounts, the daily totals are stored with us, as the privacy policy explains.

PropRuleGuard is independent and not affiliated with any prop firm. It does not give trading or investment advice.
