The economic calendar (ECO)
ECO lists upcoming and recent economic releases and central bank events by time, with their impact and the actual, forecast and prior numbers.

Why you would care
What data comes out today, and how did it compare with expectations? Every trader starts the day by checking the calendar. A jobs report or a central bank decision can move every market at once, and you want to know before it happens, not after. The calendar also tells you what "surprise" means for each number: the gap between actual and forecast.
The idea from scratch
Governments and central banks publish data on a fixed schedule: inflation, jobs, retail sales, business surveys, trade, housing, rate decisions, and speeches by officials.
For each release the calendar shows:
- Actual
- The number just published
- Forecast
- The consensus: the median of economists' forecasts
- Prior
- The previous release (sometimes revised)
- Impact
- How much this release usually moves markets: low, medium, high
The market reacts to the surprise: actual minus forecast (chapter 01, How information reaches prices and The macro machine).
Not every number is "good when higher": higher unemployment claims are bad news for the economy; higher inflation can be bad for bonds.

Practice and recap
Try it3 tasks
- Which US release in the screenshot surprised most, in percent? (New home sales: 684K vs 615K, about +11%.)
- Is a lower-than-forecast unemployment-claims number good or bad for the economy? (Good: fewer people lost jobs.)
- Why do speeches by officials appear on an economic calendar? (They can change expectations for interest rates.)
Common mistakes4 mistakes
- Reading the color as good or bad news; it shows only above or below the forecast.
- Ignoring revisions to the prior number, which can matter as much as the new one.
- Forgetting time zones.
- Treating low-impact releases as irrelevant on quiet days: they can still move a single market.
Check yourself3 questions
- What three numbers does each release show?
- What is the surprise?
- Why can a higher number be bad news?
Answers
- Actual, forecast (consensus) and prior.
- Actual minus forecast.
- Some indicators measure bad things (unemployment claims, inflation): more of them is worse.
