Global Market Index

Overview

Index values come from the OECD share price series published on FRED, one monthly series per country, normalised so that the 2015 average equals 100 and not seasonally adjusted. A collector checks FRED every morning, keeps the newest reading as the current value and stores each year's months for history. `value` is that index level and `date` is the first day of the month it describes; `baseline` is always `2015=100`.

Without `year` and `month` you get the newest stored month. With them (paid plans) you get that exact month; `year` must be 2000 or later and not in the future, `month` must be 1 to 12, and sending `month` without `year` is rejected with a 400. A month that the series has not published yet returns a 404 rather than a nearby month.

`previousValue` and `previousDate` are the closest earlier stored month, and `changeDirection` compares the two. The paid `change1m` to `change12m` fields are percent changes against the reading exactly that many months earlier, rounded to four decimals, and are null when that month is missing. `changeYtd` is measured against the previous December, so for a January reading it equals `change1m`. `high12m`, `low12m` and `average12m` cover the twelve months ending at the returned one and need at least two stored readings. `history`, only on paid plans with `history=true`, lists those months oldest first.

Formula

One function covers the whole catalog: the first argument names the source, the next are its inputs, and the field after them says which single value lands in the cell. Formulas covers the grammar that applies to all of them.

=VERVE("globalstockmarket", A2, "countryName")

=VERVE.CALL("globalstockmarket", A2, "countryName")

A2 holds the country you are looking up. Drag the formula down and each row resolves on its own.

With literal values

Nothing has to come from a cell — typed values work the same way.

=VERVE("globalstockmarket", "DE", "countryName")

=VERVE.CALL("globalstockmarket", "DE", "countryName")

Inputs

Required inputs are positional, in the order below, followed by the field. Everything else is passed as a "name", value pair after that — the same shape as SUMIFS. Premium inputs are accepted on every plan but only take effect on plans that include them.

Passing an option

=VERVE("globalstockmarket", A2, "countryName", "year", 2023)

=VERVE.CALL("globalstockmarket", A2, "countryName", "year", 2023)

What lands in your sheet

The field — the argument after the inputs — is what makes the formula resolve to one cell. Its value is a dot-path from the table below, so swapping it is how you pull a different value — one formula per column.

Seeing everything at once

Leave the field out and the formula returns the whole response instead: two columns, field name on the left and value on the right, spilling from the cell you typed in.

=VERVE("globalstockmarket", A2)

=VERVE.CALL("globalstockmarket", A2)

Response fields

Paths are relative to data. Each one is exactly what the field argument accepts, so swapping it is how you pull a different value into a cell. On a plan without a Premium field the cell reads #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

Filling a whole column

Both platforms make one batched call for a column rather than one request per cell, and both cost the same — 2 credits per row looked up. How you write it differs, because the two runtimes batch at different points.

=VERVE("globalstockmarket", A2:A100, "countryName")

In Google Sheets, give the arguments ranges and the answers spill down from the cell you typed in. Custom functions there run synchronously and in isolation, so dragged cells cannot be coalesced — the range form is how a column becomes one call. The field is required here: a per-row two-column table has nowhere to spill. Use a full column per input (A2:A100, not A2) — a single-cell reference is read as row 1 only and the rest of the column comes back blank.

In Excel, type the formula once and fill down — no range form and none needed, because its runtime is asynchronous and the add-in coalesces the calls a fill produces into a single batched request. Do not hand VERVE.CALL a range: Excel flattens it into positional arguments, so A2:A100 arrives as a hundred separate arguments and the cell reads #ERR rather than filling.

Either way, column A holds your country values and the answers land beside them, one row each, blank rows skipped.

When a cell doesn't fill

A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

Before the formula works

The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet does not leak it and a collaborator without access simply sees the last calculated values.

1. Install the add-in for Google Sheets or Excel.
2. Open the side panel and sign in, or paste a key from your dashboard.
3. Type the formula above into any cell.
