REAL DATA · VERIFIABLE READ
We Filter the Truth from Market Noise.
Financial insight built on real-time market data, multi-layered analysis, and a principle of a verifiable record.
The whole market, on one screen.
Crypto, US and European equities, BIST, TEFAS funds, FX, macro, commodities, derivatives and indices — ten separate desks, each from its own source.
Price, 24-hour change, gainers and losers, and technical levels in one table; every row opens its own chart. Crypto is the only genuinely live tape on the site.
The equity universe we collect, in one searchable table: summary, performance and fundamentals column packs, sector filters and the day’s movers. Fundamentals exist for the US and Türkiye; where they do not, the table is not shown empty — it says so.
Size, investor counts, category mix and flows; every fund has its own page with NAV history and its profile. TEFAS does not price every fund every session — the screen states how many reached the latest one.
The TCMB rate board and cross rates, FED–TCMB–ECB–BoE policy rates, inflation and bond series. Every series names its source beside it.
Every screen states its own cadence. Crypto is a live tape; the TCMB rate is an indicative fixing published once a day; TEFAS fund prices are end of session. Labelling all three "live" would have been easy; it would not have been true.
The US desk: index strip, searchable universe, sector filters and the day’s extremes — all on one screen.
A desk that reads the data.
Eight analysis identities, each looking at exactly one subject: technical analysis, market sentiment, economic indicators, risk management, portfolio diversification, global events, market analysis, and BIST/KAP commentary.
These analysts are Mergen's analysis identities, not real people — every analysis is generated from real data.
Only one identity reports a technical picture — the technical analyst: positive, neutral or negative. The others report none, and are not dressed up as if they had: their card reads "watching". A reading older than seven days is dropped, so a stale reading never looks current.
No card carries a hit rate, a success percentage or an analyst score. We hold no such record, and we do not fill a missing number with an approximation.
Disclosures filed by BIST companies to the Public Disclosure Platform arrive through the day, each sorted into high-impact, important or routine. That sorting is not a model: it is an explicitly written rule set that recognises twenty defined categories — dividends, buybacks, capital increases, mergers, financial reports — from the subject line. Because it is a rule set, why something was marked important can always be shown.
Beneath the surface.
The list screen is where you start. Every instrument has its own page, and every desk its own depth.
NAV history, total size, investor count, category and fund type — with TEFAS named as the source at the top of the page.
Funding rate, open interest, long/short split and basis. The data comes from Binance perpetuals only — venues are not blended, and the screen says so.
Total value, daily change, profit and loss, and asset allocation — in TRY or USD. If a holding cannot be priced, the count is stated at the top of the page. Your portfolio is visible only to you.
A fund’s page: NAV history and profile, sourced from TEFAS.
Proof, not speculation.
No pumps, no gurus, no promises. Real data or nothing — and that is not a slogan but four rules the code obeys right now.
The data service has no write endpoint at all; every endpoint reads. The data itself is opened read-only.
A symbol we hold no series for does not open a page — it returns 404. We would rather not open the page than render an empty one.
The fabricated performance ledger and the fixture-backed endpoints were deleted; tests confirm on every build that they have not come back.
News summaries are written in our own words — we do not even have a field that could carry someone else’s article text.
Mergen is a financial-data terminal brought together on one screen, and an analysis brand built on top of it.
