# Forecast vs Actual vs Previous: How to Trade Data Surprises

Every economic release shows three numbers: **Previous**, **Forecast**, and **Actual**. Understanding how they interact is the difference between trading the news with an edge and getting blindsided by it.

## What Each Number Means

- **Previous** — last period's figure. Your baseline for the trend.
- **Forecast** — the consensus estimate economists expect. Crucially, **the market has already priced this in** before release.
- **Actual** — the real number when it drops.

## The Golden Rule: Trade the Surprise

Markets don't react to whether a number is "good" or "bad." They react to whether it **beat or missed the forecast**.

**Example — US jobs:**
- Forecast: +200K
- Actual: +185K → a **miss** of 15K → USD typically *weakens*, even though 185K jobs is still job *growth*.

**Flip it:**
- Forecast: +200K
- Actual: +230K → a **beat** of 30K → USD typically *strengthens*.

The forecast was already in the price. Only the gap between Actual and Forecast is new information — and new information is what moves price.

## The Size of the Surprise Drives the Size of the Move

A 5K miss on jobs is noise. A 100K miss is a shock. The bigger the gap between Actual and Forecast, the larger and faster the move. This is why traders watch the *magnitude* of the surprise, not just its direction.

## Don't Forget Revisions

The **Previous** number is sometimes quietly revised when the new figure drops. A strong Actual can be undercut by a big downward revision to last month — markets notice. Always glance at whether the prior number changed.

## A Practical Framework

1. **Before release:** note the Forecast. That's the line in the sand.
2. **At release:** compare Actual to Forecast instantly.
3. **Beat** → favor the currency; **Miss** → fade it.
4. **Check the revision** to the Previous number for confirmation or contradiction.
5. **Size the trade** to the size of the surprise — small gap, small conviction.

## Why Speed Matters

This all happens in seconds. Algorithms react instantly; by the time you've manually looked up the forecast, the first move is over. Knowing the forecast *before* the release — and the exact release time — is what lets you act on the surprise instead of chasing it.
