Where our data comes from
Every figure on QuietSaving carries its source and the date it applies to. This page lists all of the sources and how often each one is refreshed.
Last updated: October 2026
How often figures are updated
The site refreshes automatically every weekday morning (European time). Stocks get the previous trading day’s data. Government bonds take the latest figure each official source has published, which is usually one to three days old for daily sources and about five weeks old for monthly ones. A figure is only ever replaced by a newer one.
Dividend stocks and REITs
- Prices, dividends, payout ratios, financial statements, analyst ratings and price targets: Yahoo Finance, collected with the open-source yfinance library.
- Dividend Aristocrats (25+ years of increases): the S&P Dividend Aristocrats index constituent lists. Dividend Kings (50+ years): public dividend-history records.
- Company filings: SEC EDGAR annual reports (10-K) as the primary reference for U.S. companies.
- Which companies are covered: the published constituent lists of the S&P 500, S&P MidCap 400, S&P SmallCap 600 and FTSE 100 (read weekly from Wikipedia’s lists of index members), plus a list of widely held dividend ETFs. Dividend streaks for these are counted from Yahoo Finance’s dividend history; see the methodology.
Government bonds: official feeds
These are read straight from the publishing institution on every update.
- United States (10, 20, 30 years): U.S. Department of the Treasury, daily par yield curve.

Bonds we don't list
We show only figures from official, free sources, refreshed automatically. Where no official source publishes a yield for free (several euro-area maturities beyond 10 years, Iceland, and all company bonds), we don't list the bond rather than copy a figure from a commercial website. When an official source becomes available, the bond comes back by itself. France's maturities beyond 10 years will return once the Banque de France feed is connected.
Exchange rates
- Euro reference rates: European Central Bank, about 30 currencies, published around 16:00 CET each working day. Pairs that don't involve the euro (for example GBP to JPY) are calculated from each currency's euro rate.
- Romanian leu: National Bank of Romania (BNR) reference rates, the official rate in Romania, published around 13:00 Bucharest time each banking day. Every pair involving the leu, and currencies only the BNR publishes (such as the Moldovan leu and Ukrainian hryvnia), use these.
Reference rates are for information. Banks, exchange offices and card providers buy and sell at their own rates. Each currency page names its source and the date of the rate shown.
Markets and earnings dates
The Markets pages show the closing values of the last completed trading day for the main stock indices, gold, silver, oil, natural gas, copper, bitcoin, ether, the US 10-year Treasury yield and the VIX, from Yahoo Finance. Commodity prices are those of the nearest futures contract. The earnings calendar shows each company's next expected results date and analysts' average forecasts, also from Yahoo Finance, refreshed on a rolling basis so every company is checked at least every three days. Dates not yet confirmed by the company are shown as a range.
Credit ratings
Issuer ratings are those published by S&P Global, Fitch and Moody’s. Where we hold no verified rating we show NR; we never estimate one. Always confirm a rating with the agency.
Retirement ages
The default retirement age in the planning tools is a typical statutory pension age for your country, which we maintain by hand. Pension ages change, so check your own government’s official figure for your situation.
