Order Blocks Explained

An order block is the last candle in the opposite direction before a strong move that breaks market structure. Here is how traders mark bullish and bearish order blocks, how order block trading works, and where it goes wrong.

6 min readUpdated Educational, not advice
TL;DR
  • An order block is the last down candle before a sharp rise (bullish) or the last up candle before a sharp fall (bearish).
  • It only counts if the move after it breaks structure. Without a Break of Structure, it is just a candle.
  • Traders mark the candle's range and watch for price to return to it.
  • A breaker block is an order block that failed and flipped.
  • The idea comes from ICT-style trading. We do not claim it predicts price.

What is an order block?

An order block is a candle, or a short group of candles, that marks where large orders are thought to have been placed before price moved hard in one direction. Traders mark it after the fact. The theory is that big buyers or sellers did not fill all their orders at once, so price may come back to that zone.

The theory is hard to prove, since we cannot see anyone's orders on a chart. What we can see is a repeatable pattern: a candle, followed by a strong move that breaks structure. In practice, that pattern is the order block. If you are searching for "what are order blocks", that is the working answer.

Bullish and bearish order blocks

Bullish order block. The last down candle before a strong move up that breaks a recent swing high. Traders expect the zone to act as support if price returns.

Bearish order block. The last up candle before a strong move down that breaks a recent swing low. Traders expect the zone to act as resistance if price returns.

The zone is usually the candle's full range, from low to high. Some traders use only the body, from open to close. Pick one and apply it consistently.

How to find an order block

Work from the move, not from the candle.

  1. Find a strong move that breaks structure. This is a Break of Structure or a Change of Character.
  2. Walk back to where the move started.
  3. Mark the last opposite-colour candle before the move.
  4. Draw the zone from that candle's low to its high.
  5. Wait to see if price returns. If price closes through the zone, drop it.

Stronger blocks, according to most traders, have a clear impulsive move away from them, form near a key level, and have not been touched since. Each coin page lists key levels you can compare against, for example the Bitcoin market structure page.

Order block example

The prices here are made up to show the pattern.

BTC is falling on the 4h chart. A down candle runs from 59,800 (high) to 59,200 (low). The next candles rise hard, closing at 61,500, and that move takes out the last swing high at 61,000. That is a break of structure to the upside. The down candle between 59,200 and 59,800 is the bullish order block.

If price returns to 59,800 and holds, a trader may enter long with a stop below 59,200. The risk is 600 points from the top of the zone, about 1.0%. If price closes below 59,200, the order block has failed and the stop is hit.

How traders use order blocks

Order block trading usually follows a pattern.

  • Find the direction with market structure on a higher time frame.
  • Mark order blocks in that direction on the same or a lower time frame.
  • Wait for price to come back to the zone. Do not chase the move that created it.
  • Look for a reaction, such as a rejection candle or a small Change of Character on a lower chart.
  • Place the stop beyond the far side of the block and size the trade from it with the position size calculator.

Nothing here guarantees a bounce. Price often passes through an order block, or reverses before it gets there.

Order blocks and breaker blocks

A breaker block is an order block that failed. A bullish order block that price closes below can turn into a bearish breaker block, which traders then watch as resistance. The idea is close to an inverse fair value gap. We mention breaker blocks so you recognise the term. A separate guide may follow.

Order blocks vs fair value gaps

Both are zones marked from strong moves. An order block is a candle before the move. A fair value gap is the gap left inside the move. They often show up together, and many traders look for an order block that has a fair value gap right after it.

Common mistakes

  • Marking every candle before a move. The move must break structure, or the block means little.
  • Using a block that price has already traded through and treating it as fresh.
  • Trading against the higher time frame trend.
  • Putting the stop inside the zone, where normal noise reaches it.
  • Expecting every block to hold. Many fail, and that is why the stop-loss exists.

FAQ

What is an order block in trading?

An order block is the last opposite candle before a strong move that breaks market structure. Traders mark its range and watch for price to return, expecting a reaction there. It is a pattern read from the chart, because the underlying orders cannot be seen.

How do you find a bullish order block?

Find a strong rise that breaks a recent swing high. Go back to where it began and mark the last down candle before it. The range of that candle, low to high, is the bullish order block. Traders then watch if price returns to the zone.

Do order blocks work?

Sometimes price reacts at them and sometimes it passes through. We have not tested order blocks as a standalone strategy and do not claim they work. They are better treated as one piece of context next to market structure and a defined stop-loss.

What is the difference between an order block and a breaker block?

An order block is the original zone before a move. A breaker block forms when that order block fails and price closes through it, so the zone flips role. A broken bullish block becomes a bearish breaker, which traders watch as resistance.

Which time frame is best for order block trading?

Higher frames such as the 4h and 1d produce fewer and more significant blocks. Lower frames produce many weak ones. Many traders find the block on a higher chart and look for an entry on a lower one.

Are ICT order blocks different from regular order blocks?

The term is mostly used in ICT-style trading. Some ICT definitions add rules, such as requiring a displacement or a fair value gap after the candle. The basic idea is the same: the last opposing candle before a structure-breaking move.
