Prop firm data with receipts.
Every prop firm comparison site tells you the rules. Almost none of them tell you when the rules change — and in this industry, they change constantly and quietly. Prop Data Lab verifies firms’ official rules, pricing, and payout terms every week, publishes the data with source links and last-verified dates, and logs every change we catch.
Start here
- The comparison table — FTMO vs Topstep vs Apex, every rule sourced, verified July 13, 2026
- Apex’s 2026 overhaul — the product line changed completely in March; most reviews haven’t noticed
- Firm profiles: Apex · FTMO · Topstep — living documents, re-verified weekly
- How we verify — official sources only, public change log, unverified means unverified
Why this exists
Retroactive rule changes are the #1 complaint traders have about prop firms — and the comparison sites that could hold firms accountable are funded by the firms they rank, with no incentive to keep receipts. We keep the receipts. Firm documentation gets archived weekly, diffed, and every change becomes a dated public record in the Rule Changes log.
More firms (FundedNext, The5ers, FundingPips, MyFundedFutures) and true-cost calculators are being added now. This site may earn affiliate commissions — read the independence policy.
