Lesson 5 of 12

An order block is a price zone where, according to smart money concepts, large institutions placed significant orders before a strong move. In practice, it is usually defined as the last opposite colour candle before a powerful move that breaks structure: the last down candle before a strong rally (a bullish order block) or the last up candle before a strong drop (a bearish order block). Traders expect price to react when it returns to that zone.

The basic definition#

Bullish order block (last down candle) Return to the zone
The last down candle before a strong move up becomes a zone price may react to later.
TypeCandleContext
Bullish order blockLast down (red) candle before a strong move upMove breaks structure upward
Bearish order blockLast up (green) candle before a strong move downMove breaks structure downward

The zone is usually drawn from the candle's high to its low, or more conservatively from its open to its wick extreme.

What makes an order block valid#

Most candles before a move are not meaningful. SMC traders typically require:

  1. Displacement: the move away from the block is strong and fast, with large candles. See Displacement.
  2. Break of structure: the move breaks a recent swing high (bullish) or low (bearish). See Break of Structure.
  3. Imbalance: the move leaves a fair value gap, showing one sided pressure. See Fair Value Gaps.
  4. Unmitigated: price has not yet returned to the block since it formed.
  5. Context: the block aligns with the higher timeframe trend and sits in a discount (lower half) of the range for longs, or premium (upper half) for shorts.

Trading an order block#

Common approaches:

  • Limit entry at the block: place a buy limit at the top of a bullish block or at its midpoint.
  • Confirmation entry: wait for price to reach the block and show a lower timeframe change of character before entering. See Change of Character.
  • Stop: beyond the far side of the block.
  • Target: the next liquidity pool, such as the recent high. See Liquidity in Smart Money Concepts.

Order blocks vs supply and demand zones#

Order blocks are a specific version of the older supply and demand zone concept. Supply and demand traders mark the base area before a strong move; order block traders narrow it to the last opposite candle. The logic, that unfilled orders may remain where a strong move started, is the same. See Supply and Demand Zones.

What happens when an order block fails#

If price trades through an order block and closes beyond it, the block is invalidated. In SMC, a failed order block can become a breaker block, which then acts in the opposite role. See Breaker Blocks.

A realistic view#

Order blocks are easy to find on past charts because you can see which ones worked. In real time, many candles look like potential order blocks and most are never respected. The useful parts are the requirements for displacement, structure and location, which filter out weak zones. Test precise rules on a large sample rather than trusting hand picked examples.

Common mistakes#

  • Marking every last candle before any move as an order block.
  • Ignoring trend and location; a bullish block in a downtrend fails often.
  • Placing stops too tight inside the block.

Frequently asked questions#

What is an order block in trading?#

A zone, usually the last opposite candle before a strong move, where large orders are believed to have entered and where price may react when it returns.

How do you identify a valid order block?#

Look for strong displacement away from it, a break of structure, an imbalance left behind and alignment with the higher timeframe trend.

Are order blocks the same as supply and demand zones?#

They are closely related. Order blocks are a narrower, SMC specific way of defining where a strong move began.
