What Is an Order Block, Including Breaker Blocks?

An Order Block is a price area where smart money may have placed large orders before a strong move happened.

When these institutions enter the market, their order sizes are too large to be executed all at once without causing immediate, drastic price movements.

Therefore, they leave behind "blocks" of unexecuted orders. When the price eventually returns to this zone in the future, these remaining orders are triggered, usually causing a sharp price reversal.

How to Identify an Order Block on a Chart

In standard Smart Money Concepts (SMC), an Order Block is identified by looking at the very last candle before a sharp, aggressive price move.

• Bullish Order Block (Buy Zone): The last down-close (bearish) candle right before a strong, impulsive upward move that breaks the market structure (BOS).

• Bearish Order Block (Sell Zone): The last up-close (bullish) candle right before a strong, impulsive downward move that breaks the market structure (BOS).

Rules for a "High-Probability" Order Block

Not every last candle is a valid Order Block. To find the most reliable ones, look for these three characteristics;

1. Imbalance / FVG: The aggressive move leaving the Order Block must create a Fair Value Gap (FVG) immediately after it. This proves that institutional volume was genuinely behind the move.

2. Market Structure Break (BOS/CHoCH): The strong move generated by the Order Block must successfully break a previous high or low. If it doesn't break the structure, the block is weak.

3. Liquidity Sweep: High-probability Order Blocks often form right after taking out the stop-losses of retail traders (a liquidity hunt) before reversing the other way.

What is a Breaker Block?

A Breaker Block is a failed Order Block that has been invalidated due to a rapid, high-momentum price movement.

When the price decisively trades through an existing zone following a liquidity sweep or a Market Structure Break, that area "flips" its role to act as a high-probability support or resistance level during future retests.

Two Types of Breaker Block

1. Bullish Breaker Block

A bullish breakout block is the last upward closing candlestick formed at the most recent swing high before the market falls to its lowest point in a liquidity sweep.

If the price then breaks strongly above that swing high with a powerful upward surge, the original sell order block is invalidated (flips), becoming a valid "bullish breakout block." This acts as a strong support line for opportune long entries.

2. Bearish Breaker Block

A bearish breaker block is the last closing candlestick of a decline within a swing low that formed before the price rose and drew out liquidity.

When the subsequent sharp decline decisively falls below the preceding swing low, the bullish order block becomes invalid flips), and it is confirmed as a valid "bearish breaker block." This acts as a strong resistance level against future short entries.

How Traders Use Order Blocks

Traders do not chase the market when a big move happens. Instead, they exercise patience and use Order Blocks as a limit order zone:

1. Identify a valid Order Block that caused a break of structure (BOS).

2. Draw a horizontal zone covering the entire body (or wick-to-wick) of that specific candle.

3. Wait for the price to retrace back down (or up) into this zone.

4. Enter a trade inside the zone, placing the Stop Loss just outside the opposite edge of the Order Block candle to minimize risk.

How to Use Order Blocks for Entries

An Order Block can be used as a potential entry zone, but it should not be used alone.

The basic idea is to wait for the price to return to the Order Block after a strong move.

Then, instead of entering immediately, you can look for confirmation on a lower timeframe.

This helps reduce the risk of entering too early.

Basic Entry Process

A simple Order Block entry process may look like this:

1. Identify the higher-timeframe direction.

2. Wait for liquidity to be taken.

3. Look for strong displacement.

4. Mark the Order Block that caused the move.

5. Wait for price to return to the Order Block.

6. Move to the lower timeframe for confirmation.

7. Plan the entry, stop loss, and target.

This process keeps you from entering randomly. It also helps you trade with structure and context.

Lesson 5 Conclusion

• In this lesson, you learned that Order Blocks are potential smart money zones where large orders may have been placed before a strong move.

• You also learned that a good Order Block should be connected to liquidity, displacement, and market structure.

• Order Blocks should not be used alone, and traders should wait for price to return to the zone with proper confirmation.

In the next lesson, you will learn Fair Value Gaps and Imbalance, which help traders understand inefficient price movement and possible reaction zones.
