What an order block is
In Smart Money Concepts (SMC), an order block is the last opposite-colour candle, or small cluster of candles, before a strong price move that breaks market structure.
- A bullish order block is the last bearish (down) candle before a sharp rise.
- A bearish order block is the last bullish (up) candle before a sharp fall.
The story behind it is that large participants, such as banks and funds, placed orders in that area. Some of those orders were not filled, so price may react when it comes back. Nobody outside those institutions can see their orders, so this is an interpretation of price, not something you can observe directly.
Order blocks overlap with supply and demand zones. The main difference is that SMC traders usually anchor the zone to a specific candle and want a structure break to confirm it.

How to find order blocks
Most SMC traders follow similar steps:
- Find a strong move. Look for an impulse: large candles in one direction with little overlap between them.
- Check for a break of structure. The move should take out a recent swing high (bullish) or swing low (bearish). Without this, many traders do not count the zone.
- Mark the last opposite candle. Before a rally, that is the last down candle. Before a drop, that is the last up candle.
- Draw the zone. Some traders use the full candle range from high to low, including the wicks. Others use only the body, or the area from the open to the wick. Pick one method and use it every time.
- Look for supporting signs. Traders often want a fair value gap left by the impulse, or a liquidity sweep just before the move.
- Wait for a return. The order block only becomes a point of interest if price comes back to it. Many zones are never revisited.
A drawn example (no live prices)
Reading the sketch: price makes a swing high, pulls back with a down candle (shaded), then rallies hard and breaks that swing high. The shaded candle becomes the bullish order block. Later, price returns into the zone. What price does next is not known in advance. It can hold, react briefly, or cut straight through.
Failure modes
Order blocks fail often. These are the common reasons:
- Hindsight drawing. After a move, it is easy to find a candle that "explains" it. In real time, several candles can qualify, and you only learn which one mattered later.
- Too many zones. On lower timeframes almost every swing produces an order block. If every candle can be a zone, the zones lose meaning.
- Inconsistent edges. Wick versus body changes the zone size a lot. A stop placed just outside a narrow body zone can be hit by normal noise.
- Context ignored. A bullish order block inside a clear downtrend on a higher timeframe is weaker. See multiple timeframe analysis.
- News and volatility. Economic releases can move price through any zone without a pause.
- Mitigated zones. Once price has returned and reacted, many traders consider the zone used. Trading the same zone again and again usually works less well.
A fair critique
The ideas behind order blocks are not new. "Last candle before the move" is close to older supply and demand methods and to basic support and resistance. The label "institutional" adds a story but no extra data. Retail traders do not see order flow, and in decentralised forex there is no central order book to check.
There is also no reliable public evidence that order blocks have a stable edge on their own. Results you see online are often hand-picked screenshots. If you want to judge the method, write down exact rules, mark zones in real time, and record every outcome, including the zones that failed.
Leveraged forex and CFD trading can lose money fast, and a zone on a chart does not limit that risk. Position size and stop placement matter more than the zone itself. Read risk management before you use any setup with real money.
Frequent questions
Are order blocks the same as supply and demand zones?
They are very similar. Order blocks are usually tied to a specific candle and to a break of structure, while supply and demand zones are often drawn more broadly around a base.
Which timeframe works best for order blocks?
No timeframe is proven to work best. Higher timeframes produce fewer zones and less noise. Lower timeframes produce many zones, and many of them fail.
Should I use the wick or the body?
Both methods are used. Wicks give a wider zone, and bodies give a narrower one. Consistency matters more than the choice.
Do order blocks show where banks placed orders?
No. They are a way of reading past price action. Retail traders cannot see institutional orders.
How can I practise finding order blocks safely?
Mark zones on historical charts without looking ahead, then follow them forward and record the results. A demo account lets you test in real time without risking money. Learn related ideas in price action and technical analysis.
