Our standards
Editorial Standards
Every guide on this site is researched against primary sources, written in plain language, and reviewed on a schedule. This page explains exactly how — including what we refuse to do.
Who writes our guides
Guides are written and reviewed in-house by the Yunjx Editorial Team. We do not publish contributed posts, guest articles, or externally supplied content, and we do not use freelance marketplaces for finished articles. This matters because currency content is unusually easy to get subtly wrong: a rate direction flipped, a fee described as a spread, or a “typical” margin quoted from a single provider and presented as a market norm.
Each article carries a byline showing the team responsible and the date it was last reviewed. Where an article states a specific rate, fee, or price, the date that figure was observed appears in the text next to it, so you can judge how fresh it is. Reference rates move daily; the patterns we describe move far more slowly, and we label which is which.
Primary sources we rely on
We prefer the original publisher of a number over anyone quoting it. In practice that means:
| Claim type | Source we use | Update cadence |
|---|---|---|
| Euro reference rates | European Central Bank daily euro foreign exchange reference rates | Each business day |
| Dollar exchange rates | US Federal Reserve H.10 foreign exchange release | Weekly / monthly series |
| Market size and turnover | BIS Triennial Central Bank Survey of foreign exchange | Every three years |
| Card network rules | Published network and issuer fee disclosures | Reviewed annually |
| Consumer fee ranges | Our own documented provider testing (below) | Reviewed quarterly |
When we cannot reach a primary source, we say so in the article rather than presenting an unverified figure as fact. Where a number is genuinely an estimate — a typical airport margin, for example — we present it as a range and explain what drives the variation.
How we test fees and spreads
The most useful thing we publish is the difference between a mid-market rate and a rate a real person is offered. To measure that difference honestly, we use a fixed method rather than impressions:
We take a single notional payment, hold the amount and corridor constant, and price it through each route using publicly displayed retail quotes captured on a stated date. We then convert every result into one comparable figure: the amount that actually lands. Rates, margins and fixed fees all collapse into that number, which is why our tables show delivered amounts rather than percentages alone.
We do not accept payment to rank or feature any provider, and our comparisons are not affiliate-driven. Because retail pricing varies by country, card type and account, we present these results as representative illustrations and always tell readers to confirm their own quote before transacting.
Review and update process
Every guide is reviewed at least every six months, and sooner when something material changes — a network rule change, a new disclosure requirement, or a shift large enough to invalidate an example. A review checks three things: that cited figures still match their source, that worked examples still produce the stated result, and that any claim about costs still reflects how the market behaves.
When we update an article we change the review date shown in the byline and the structured data on the page, so the freshness signal you see matches the content rather than the file.
Corrections
If we get something wrong, we fix it and say so. Substantive corrections — a wrong figure, a misattributed source, a calculation error — are corrected in place with the review date updated. Where a correction would change a reader’s decision, we add a short note at the point of the change describing what was corrected. You can report an error via the contact page; we read everything, and we prioritise anything that affects money.
Independence and funding
The site is free and funded by advertising. Advertising has no influence over which providers we compare, how we rank them, or what we conclude. We do not sell links, placements, or favourable mentions, and we do not publish sponsored articles.
Nothing here is financial, investment, tax, or trading advice. Our purpose is education: to help you ask better questions of a provider and understand the numbers you are shown. That boundary is stated in our disclaimer and repeated wherever an article touches a decision with real money at stake.
What we do not publish
We do not publish rate forecasts or price targets, because the evidence that anyone can forecast major currency pairs reliably over useful horizons is weak, and readers lose money acting on false confidence. We do not publish content generated and published without human review. And we do not republish material written elsewhere under our own name — every guide here is written for this site, and the worked examples are ours.
