What Is an Order Block in Smart Money Concepts?
An order block is the last candle before a strong, structure-breaking move — a zone traders watch for price to react to on a return. Here is how to identify one and its limits. Educational, not financial advice.
An order block is the last down-candle before a strong upward move (a bullish order block), or the last up-candle before a strong downward move (a bearish order block), that breaks market structure. In smart money concepts, traders mark these candles as zones where significant buying or selling likely originated, and watch for price to react if it returns. Educational, not financial advice.
How to identify an order block
- Find a strong move that breaks structure (a clear higher high or lower low).
- Look at the last candle in the opposite direction right before that move began.
- That candle's range is the order block — the zone you mark and watch.
A bullish order block is the last red candle before a strong rally; a bearish order block is the last green candle before a strong sell-off.
Why traders use them
The reasoning is that the big move likely left unfilled orders in that last opposing candle. If price returns to the zone, traders look for their own confirmation — a reaction, a lower-timeframe structure shift — before doing anything. Like a fair value gap, an order block marks where to watch, not a decision by itself.

| Order block | Fair value gap | |
|---|---|---|
| What it is | Last opposing candle before a move | Imbalance between three candles |
| Marks | Origin of a move | Un-traded price zone |
| Used for | Zone to watch on return | Zone price may revisit |
They are often used together: an order block that overlaps a fair value gap is a higher-confluence zone than either alone.
The honest limits
- Not every order block holds — price can move straight through one.
- They are subjective; two traders can mark different candles, so define your rule and be consistent.
- Lower-timeframe order blocks are noisier. Context — trend and market structure — decides which ones matter.
Our Smart Money Concepts course covers order blocks alongside structure, liquidity and imbalance, and how to combine them — as objective zones to read, never as guaranteed entries.
Takeaway
An order block is the last opposing candle before a structure-breaking move — a zone traders watch for a reaction on return. Mark it with a consistent rule, confirm it against structure, and accept that not every block holds.
