How to check whether a prop firm changed its rules
The fastest way to check whether a prop firm changed its rules is to compare the terms page you see today against an archived copy from the day you bought. Here are four ways to do that, from quickest to most rigorous.
1. Look for a "last updated" date on the terms page
Most terms-of-service pages carry a date at the top or bottom. If the date is newer than your purchase, something changed — though the date alone will not tell you what. Some firms do not update this date reliably, so treat a stale date as "unknown", not "unchanged".
2. Use the Internet Archive
Go to web.archive.org, paste the URL of the terms page, and pick a snapshot from around your purchase date. Open it beside the live page. This is the method we recommend for anyone who wants proof, because the archive's timestamps come from a third party, not from you or the firm.
The limitation: the Archive only has a copy if someone asked it to save one. Popular pages are saved often; a small firm's rules page may have gaps of months.
3. Check the firm's page here
Every firm we track has its own page listing each public terms page we watch, the last time we read it, and a full history of every change we detected — shown as the exact lines removed and added, with a link to the archived copy of each version.
Browse the list of tracked firms. If a firm is missing, that is a gap in our coverage, not a statement about the firm — and some firms block automated readers, which we say plainly on the same page.
4. Compare the text yourself
If you kept a copy of the terms (a PDF, a screenshot, a saved page), paste the old and new text into any free online diff tool. It will highlight every line that differs. This is exactly what our monitor does, just by hand.
What to do if you find a change
Save the evidence first: the archived copy, a screenshot of the live page with the date visible, and the confirmation email from your purchase. Then read the change carefully and decide for yourself whether it affects your account. We do not give advice on what to do next — that depends on your contract and your situation, and we are not qualified to judge either.
