How EPTA5 calculates
Where the figures on this site come from, which edition they belong to, and how the three calculations shown on the home page are made: growth on the globe, seasonality year by year and the screener counters. Every number on this page is read from the same files as the home page.
Home page figures generated on 14 October 2026Sources and editions
Macro for up to 196 countries comes from public institutions: IMF, OECD, BIS, World Bank, Eurostat, and INSEE. Every chart in the terminal names its series.
IMF figures come from the World Economic Outlook, October 2026: a database published on 13 October 2026, with country series from 1980. The next full edition is expected in April 2027; as of 13 October 2026, the IMF had not announced its day. The home page uses the edition the terminal uses.

Analyses derived from IMF data are the sole responsibility of EPTA5 and do not engage the IMF.
Markets: daily closing prices, at the end of each trading day. No real-time quotes.
History: Terminal shows the last 25 years; Terminal Pro shows the full history, back to 1942 for the oldest macro series.
Growth on the globe and the country sheets
The globe colours each country by its real GDP growth (series NGDP_RPCH: gross domestic product at constant prices, annual change in %), for its last observed year.
The last observed year is the latest year of actual data that the IMF gives, country by country and series by series; the years after it are IMF staff projections. The globe and the Vision 360 sheet show observed years only; the Country Monitor also shows the projections, marked “e”.
Some economies report by fiscal year. The IMF places a fiscal year that starts in the first half of the calendar year, such as April to March, in the column of the year in which it starts, and one that starts in the second half, such as July to June, in the column of the year in which it ends. The terminal follows that convention.
Colour scale: from −8% to +8%, in 8 equal bands; a value beyond a bound takes the colour of that bound. In the edition in use, 152 of the 196 economies with an observed growth figure are coloured, as on the terminal’s map. The other 44 stay grey: mostly small states and territories that the map does not draw, such as Singapore and Hong Kong. Some countries drawn under another name are not matched by the terminal’s map yet either, such as Iran and Tanzania.
Each country sheet shows four IMF series, each with its own year:
- real GDP growth, annual change in % (NGDP_RPCH);
- inflation, average consumer prices, annual change in % (PCPIPCH);
- general government gross debt, in % of GDP (GGXWDG_NGDP);
- general government net lending or borrowing, in % of GDP (GGXCNL_NGDP).
In each country sheet, a figure turns green when it falls within these ranges: growth above 0%; inflation from 1% to 3%; gross debt at or below 60% of GDP; balance at or above −3% of GDP. The other figures keep the text colour. These ranges are display markers set by the terminal, not a rating of the country.
The curve under the figures is real GDP growth over the last 24 observed years.

Seasonality, year by year (Focus)
A window is an entry date and an exit date, each a day and a month, the same every year.
For each year, the entry price and the exit price are read on the asset’s daily series. When there is no quote on that day, the price is interpolated linearly between the two quotes around it if they are 100 days apart or less; otherwise the nearest quote within 120 days is used; otherwise the year is left out.
The return of a year is the exit price divided by the entry price, minus one. A year is up when its return is above zero, and down otherwise.
The Focus screen counts the up years and the down years, gives the average return of each group, the highest and the lowest yearly return, and the number of trading sessions in the window. Every year is shown, and the worst one is highlighted.
Terminal shows the last 25 years; Terminal Pro shows the full history of the asset.
This measures what happened in past years. It is not a forecast.
The example on the home page
EURUSD (Euro / US dollar), the euro’s reference rate against the US dollar, published each working day by the European Central Bank. Window: 21 April to 2 August, the default window of the Focus screen, fixed before the calculation. Daily ECB reference rates, 1999 to 2026: 28 years, all listed below. Rose in 14 of 28 years; worst year: 2005, -6.44%. EPTA5 calculation, Focus screen of the terminal, reference rates up to 14 August 2026. Source: European Central Bank; the yearly returns are calculated by EPTA5, not published by the ECB.

878 of the 896 series have daily closes; the other 18 are monthly series or have sparse quotes.
In the screener, each card counts the assets left after the filters already chosen.
BRAIN AI and its sources
BRAIN AI answers first from the terminal’s data. Under the answers that rely on sources, a “Sources · N” panel lists them, so that you can open them and check.
It is instructed to say when a figure is not in the data. It can be wrong. It explains the data; it does not recommend buying or selling, and the decision stays yours.
What the home page shows
Real screenshots of the terminal, in English, taken in production on 13 October 2026 (Japan sheet), 13 October 2026 (Germany sheet), 13 October 2026 (globe), 9 October 2026 (Stocks card), and 9 October 2026 (BRAIN AI welcome screen): the country sheets of Japan and Germany, and, in the overview, the globe, the Stocks card of the screener and the BRAIN AI welcome screen.
Animated reconstructions, drawn by this site in each language on the terminal’s data: the globe of the first screen and of Explore (IMF, World Economic Outlook, October 2026), the screener (price index of 3 October 2026), the Focus screen (ECB reference rates up to 14 August 2026) and BRAIN AI. Each one carries the label “Animated reconstruction” and a caption with its source and date.

The BRAIN AI exchange is a reconstruction, not a recorded answer: a general explanation of the World Economic Outlook, checkable against the 2 real sources it lists.
In the overview, the “Measure seasonality, year by year” thumbnail is a drawing of the Focus window selector, with no figure.
