> Order Flow means reading the real flow of orders instead of lagging indicators. Here's how it works, and why pro traders swear by it.
Most beginners pile up indicators (RSI, MACD, moving averages) that merely **recompute the past**. **Order Flow** flips the problem around: it looks at what's actually happening in the order book, in real time.

## Order Flow in one sentence
It's the analysis of the **order flow**: who's buying at market, who's selling, at what price, and how aggressively. Instead of guessing, you see the real mechanics that move price.

## The building blocks
- **The footprint**: each candle broken down bid × ask, level by level.
- **Delta**: the difference between aggressive buying and aggressive selling volume.
- **Imbalances**: marked excesses between the two sides.
- **Absorption**: when a large limit order soaks up aggression without giving way.

If these terms only half make sense, that's normal — we break them down one by one on the [forum](/forum) and in our [courses](/cours).

## Why it's powerful
An indicator tells you *that* price went up. Order Flow tells you *why*: a sell absorbed, a liquidity vacuum, institutional aggression… You anticipate instead of reacting.

> We don't read the future. We read the participants' intent, where it shows: the order book.

## Where to start?
1. Understand the order book and the footprint.
2. Learn to read delta and its divergences.
3. Practice spotting [absorption and icebergs](/blog/absorption-icebergs).
4. Add the [liquidity heatmap](/heatmap) to see where the real players are.
