Methodology
RexPropFirm is a record of what prop firms publish: the current terms, where each value came from, how old the evidence is, and what changed. This page defines every number and marker on the site. It is deliberately short; the full contracts live in the project’s domain and provenance specifications.
What you are looking at
This build is a real-data research preview. Every firm is a real, publicly documented prop firm, and every accepted value was read from that firm’s own published page or a public registry and recorded in the source ledger (docs/P025.2-real-data-source-ledger.md). Aggregators, comparison sites, review platforms and community posts were used only to find candidates; none of them sets a value here.
It is not production-published data: it is a single snapshot taken at 2026-09-22 00:00 UTC (version real-preview-2026-09-22.1), pending owner review. Every age and state on the site is measured against that snapshot time, not against your clock, so nothing here ages on its own. No page fetches anything from a firm at request time. Terms change often, so check the firm’s own page, linked from every value, before acting on anything.
Two things follow. The change-history mechanism exists, and its surface is the record: a change is recorded only when two evidenced values of the same field differ, so this snapshot — a first observation of each value — legitimately holds none yet. And coverage is uneven: where research did not reach an authoritative page for a field, the field reads — (not collected) rather than being guessed from another plan or firm, which is exactly what lowers Data Confidence.
Prices in this snapshot
Where a firm published both a list price and a promotional or coupon price, Rex records the list price as the price and preserves the promotional figure in the value’s original wording. Offers are recorded in Rex’s own offers table and shown on Offers and Deals only when they meet the Deal bar — a named plan or account, a stated benefit and both validity dates. None of this snapshot’s promotions published a validity window, so no offer qualifies as a Deal and that list is honestly empty. Prices are never converted between currencies.
Source authority and page counts
Rex prioritizes pages the firm controls — its own site, terms, help centre and agreements — and public company registries. Research may also be accepted through an explicit owner review; those records retain their original URLs and a manual-verification source type. This acceptance does not identify a third-party page as an official source. Where a firm publishes the same figure in two places, Rex records the more specific page.
Rex counts pages, not readings. A page is one canonical address; a capture is one reading of it. This snapshot cites 151 source pages across 155 captures. A pricing page can be read more than once to record different selector states. Two captures of one address are not two independent sources, so the public figure is always the page figure. 3 capture records are held but cited by no published value, and are excluded from every count. The source registry lists every one of them.
Accepted versus provisional
An accepted value passed source review or explicit owner review and carries the time its source was read. A provisional value is Rex’s own reading of weaker evidence — an inference from what a page shows rather than what it states — and it renders with a visible UNVERIFIED marker everywhere it appears, never only in a tooltip. Operating status is the clearest case: almost no firm publishes a status field, so Rex observing that accounts are on sale is an inference, and the badge says so.
A provisional value never becomes accepted by being displayed, aggregated or aged. It becomes accepted only when an eligible source states it.
Captured, detected, verified, effective
- Captured: when Rex fetched or rendered the page. A capture time is evidence that a page was read, not that a human confirmed the value.
- Detected: when Rex first held this value for this field.
- Verified: when an eligible source last confirmed the value. Every age and state on the site is measured from here.
- Effective: when the firm says the term itself began to apply. Only the firm can supply this, so it is often absent.
A capture time is never silently promoted into a manual verification. Where the only evidence is that Rex read a page, the value carries the source and the read time and nothing stronger.
First observation versus change
A change needs two accepted observations of the same field, or an official announcement that states both the old and the new value. One observation is a first observation: it establishes what the value is and asserts nothing about what it was. Rex will not present a freshly verified value as a change, will not treat a newly researched firm as a wave of updates, and will not fill the record with activity that did not happen.
Trader reviews
A review is submitted by a signed-in trader and starts pending. It becomes public only after a person approves it; a rejected or hidden review is never shown. The rating on a firm’s reviews tab is the aggregate of approved reviews only, kept in one canonical summary so the firm page, the reviews tab and the site-wide list cannot disagree. A firm with no approved reviews shows no rating rather than a zero. This is a user rating: it is not a Rex Score, it does not feed one, and it is not a claim that Rex verified every statement inside a review.
Verified payout reports
A payout here is a trader’s report that somebody submitted and a person verified — not a payout figure the firm published, and not the firm’s total payout history. Rex holds only the reports in its own record, so any figure is the sum of verified reports Rex has, never the amount a firm has paid overall. A report starts pending and counts for nothing until it is verified; pending and rejected reports are on no public page. Amounts are shown in the currency they were reported in and are never converted or added across currencies. Region is the reporter’s stated region, not their exact location, and an unknown region stays unknown.
Offers and Deals
An offer is a commercial record in Rex’s own offers table: a firm, a benefit, and a validity window. It appears publicly only while its stored status and window make it live, and a draft or paused record is never published. It becomes a Deal only when the record carries the exact plan or account, a stated benefit and both a valid-from and a valid-to date; anything less stays on Offers and out of Deals. A coupon code is never shown in full — only masked — and no affiliate destination is ever placed on a public page. What each offer changes is worked out once, in one engine, so a card and the firm’s own page cannot show two different effective prices.
Affiliate status of this preview
No affiliate relationship is expressed anywhere in this preview. Firm pages carry no affiliate token, the Visit and Offer controls are disabled, and the only outbound links are ordinary official source links used for provenance.
Counts
- Prop Firms: firms whose operating status is active, paused or under review. Closed firms are excluded.
- Challenge options: purchasable account variants, that is, one account size of one challenge with its own price and rules. A firm with three sizes of one challenge has three options. The word “Challenges” is never used for this count.
- Active Deals: verified offers whose validity window includes the dataset time.
- Changes This Week: material changes detected in the seven days before the dataset time, excluding retracted events. Counting uses the detection date, so a late-detected old change counts in the week Rex saw it and shows its earlier effective date.
- Detected today: a change whose detection time falls on the same UTC calendar date as the dataset time. It is never inferred from a compact age label.
- Quick Finder and country facets: count only options whose firm states availability as allowed for the selected country. Unknown eligibility is excluded and reported separately; it is never counted as a match.
Prices, budgets and ordering
A price belongs to one class: its currency and its fee type (one-time or recurring monthly). Rex orders amounts only inside one class. When a result set spans several classes, the price sort groups rows by class and orders within each group; no single cheapest-to-most-expensive order exists across classes and no exchange rate is ever applied. Budget bands are defined per currency for the list price per charge. A firm’s starting price is listed per market and per class (“from $299 one-time”, “from $149/mo”), never as one unqualified figure.
Compare compatibility
Each compared field is comparable only when unit, type, basis, measurement, currency and fee type all match; comparable with note when only a stated basis or trailing stop point differs; otherwise incompatible, with the reason shown. A one-time fee and a monthly fee, a EUR and a USD amount, a percent and a currency limit, a static and a trailing drawdown, or an intraday and an end-of-day measurement are never compared as numbers. With three options the worst pair decides the field and every pair’s reason stays visible. Non-values keep their own meaning (n/a, NOT PUBLISHED, —) and are never merged into one blank.
Source states
Each value carries a small marker. Activate a value to open its provenance.
| Marker | Meaning |
|---|---|
| ✓ 3H | Verified: an eligible official source confirmed this value 3 hours ago, within its freshness window. |
| 21D | Stale: the last verification is older than the window for this kind of field, but within the hard limit. |
| EXPIRED 91D | Past the hard limit. Still the last known good value, still shown, but treated as unevidenced in Data Confidence. |
| UNVERIFIED | Provisional: no official source has ever stated this value; a lower-authority source is shown until one does. |
| CONFLICT | Two eligible official sources disagree. The accepted value stays; the contested value is in the popover. |
| NOT PUBLISHED | The firm’s materials were read and do not state this value. |
| — | Not collected: Rex has not yet captured a source for this field. |
| n/a | Not applicable: the concept does not exist for this option (for example weekend holding on futures). |
| NO SOURCE | Reserved for demo or seed data with no capture at all; never a real production fact. |
Row chips summarise the critical fields of a row with the worst case: CONFLICT beats EXPIRED beats STALE beats UNVERIFIED beats PARTIAL; a green tick uses the oldest verification among the row’s critical fields, so a row never looks fresher than its least-recently-verified value. “Updated” is a separate figure for the newest detection and is never a verification claim.
Freshness windows
| Category | Window | Hard limit |

| pricing | 7 days | 30 days |
| operating status | 14 days | 45 days |

| platforms | 60 days | 180 days |
| country | 90 days | 180 days |
| identity | 180 days | 365 days |
| descriptive | 365 days | none |
Data Confidence (DC-0.1)
Data Confidence is the weighted share of an object’s applicable fields that are currently evidenced, discounted for staleness and conflict. It measures how well Rex knows the published terms, not how good the terms are.
- Field scores: verified 1.0; verified with a missing sub-field 0.75; stale 0.5; conflicting 0.3; unverified 0.2; expired, not published or not collected 0. Not-applicable fields are excluded from both numerator and denominator.
- Critical fields (price, fee type, loss limits, target, evaluation structure, split, first payout, operating status) weigh 2; other material fields weigh 1.
- A firm’s figure combines its own fields with a variant block weighted like one typical challenge option (the median variant weight) and covered by the mean of its options, so large catalogs neither dominate nor hide weak options. The lowest option coverage is always shown, and below 50% the band is capped at “Partial data”.
- Bands: 90% and above normal; 70–89% “Partial data”; below 70% “Low data coverage”. Nothing can raise the figure except new evidence; missing or stale data can only lower it.
Research Depth
Research Depth records the breadth of accepted evidence behind a firm. Full research means published facts cite at least two distinct accepted source pages, including any explicitly accepted manual research; partial research means only one page is cited so far. This does not mean every field is complete. Two captures of one address count as one page, so re-reading a page never promotes a firm.
It is a statement about Rex’s coverage, not about the firm. A partial firm is not riskier, worse run or less trustworthy than a full one; it is one Rex has read less of. Research Depth is separate from Data Confidence, which measures field-level coverage of what was read, and separate again from Rex Score, which does not exist yet.
Change dates
A change record keeps two dates: when the firm says a term became effective, and when Rex first detected it. Both are shown when both are known (“Effective Aug 1 · detected Aug 5”). When the firm states no effective date, the record says “Detected”. Lists are ordered by detection date, which never moves; retracted events stay in full history but leave the public counts.
Rex Score
Rex Score is a separate, versioned quality methodology that has not been published. Until it is, every score surface shows “not yet scored”, the Rankings page explains the gap, and no field of Data Confidence feeds into it. The two figures are never rendered in the same visual grammar.
Affiliate policy
No affiliate relationship is expressed anywhere in this preview: no firm page carries a token, the outbound controls are disabled and say so, and the only external links are ordinary official source links used for provenance. If commercial relationships ever exist, they will be disclosed here and will still be unable to change any value, state or count on this site — offers would appear only inside a firm’s or option’s own context, next to its confidence, and never as banners.
Corrections
A value is replaced only by an eligible official source or an evidence-backed manual resolution. Errors are corrected by retraction records, never by deleting history. See the rules glossary for the vocabulary used on every page.
