Breaker blocks: when an order block fails

A breaker block is an order block that failed. Price closed through the block instead of respecting it, and traders then watch the same zone from the other side. A failed bullish order block becomes a bearish breaker, expected to act as resistance. A failed bearish order block becomes a bullish breaker, expected to act as support.

The idea comes from ICT (Inner Circle Trader) teaching. The reasoning is that traders who defended the block are now trapped on the wrong side, and may close out when price returns to the zone, pushing it away again. Whether that happens often enough to matter is a separate question, answered honestly further down.

How a breaker block forms

1. An order block forms. A candle closes beyond a swing high or low, and the last opposite candle before it becomes an order block.
2. The first return closes through it. Price comes back into the zone and the hour closes beyond it: below a bullish block, or above a bearish one. The block failed.
3. The zone flips. From that hour on, the same zone is a breaker on the other side. A failed bearish block is a bullish breaker; a failed bullish block is a bearish breaker.
4. The breaker’s first return decides. The first later hour that trades back into the zone settles it: held if it closes without going through, otherwise the breaker is done.
5. Life. A breaker nobody returns to expires 72 hours after the failure.

Bullish order block (price closed below it)	Bearish breaker	Resistance when price comes back up
Bearish order block (price closed above it)	Bullish breaker	Support when price comes back down

The swings, breaks and blocks follow the exact rule on the order block page, on one-hour candles. The same rule is written into EdgeDepth’s research engine; it has not been released there yet, so the record does not count breakers today.

A real example: Bitcoin on 15 October

15 October was a sell-off morning. At 06:00 UTC, BTCUSDT made a swing low at 80,455.0. The 07:00 hour was an up candle from 80,784.6 to 81,534.2, the last up candle before the next leg down. (The 08:00 hour reached a slightly higher 81,540.0 but closed down, so it is not the block.) At 13:00 an hour closed at 80,164.5, below the swing low. That close made the 07:00 candle a bearish order block.

It lasted one hour. The 14:00 hour reversed and closed at 81,840.5, above the top of the block. The block failed, and the zone became a bullish breaker: what had been read as resistance was now read as support. Many ICT traders would read the drop below the swing low and the reversal straight after it as the liquidity sweep that comes before a breaker.

Price did not come back for more than a day. At 15:00 on 16 October an hour fell to 81,289.2, inside the zone, and closed at 81,320.1: by the rule, the breaker held. Two hours later, at 17:00, a wick reached 80,780.0, just under the zone’s low, before price recovered to 81,694.6 by 20:00. The rule had already counted the breaker as held; a stop just under the zone would have been hit by that wick. That gap between “held” and a trade that survived is the whole difficulty with breakers.

This example was chosen because it shows every part clearly. The same sell-off is the Hyperliquid example in the liquidation heatmap guide. To replay it tick by tick, open BTCUSDT in the terminal, right-click a candle and choose Replay from here; Pro reaches back 30 days. How to start a replay.

Breaker block, order block or mitigation block?

In stricter ICT usage, a breaker needs a liquidity sweep first: price takes out an old high or low, then reverses through the block. Without that sweep, some traders call the same flip a mitigation block. The rule on this page does not require the sweep, so it counts both.

What the order flow shows

The failure. A block that fails quickly is usually overrun, not slowly worn down. Look at what did it: a burst of aggressive orders on the tape and, on perpetuals, reported liquidations of the side that was leaning on the block. Short liquidations when a bearish block fails; long liquidations when a bullish one does.

The retest. For a bullish breaker, watch for bids resting inside the zone on the order book heatmap as price comes back, and for selling that gets absorbed there rather than pushing through. A footprint of the retest hour shows how much traded at the bottom of the zone.

The wick. As in the example, price can trade under a bullish breaker and close back above it. That is a sweep inside the retest. The rule counts the close; a trade has to survive the wick.

Are breaker blocks reliable?

By this rule, breakers are rare, because most order blocks hold on their first return and never fail. On BTCUSDT, ETHUSDT and SOLUSDT, 15 September to 17 October 2026 (UTC), the rule found 191 order blocks. Price came back to 157 of them; 16 failed and became breakers. Of those 16 breakers, 12 held on their first return, 2 were closed through, 1 expired untouched and 1 was still open at the end.

That is far too few to say anything about whether breakers work, and “held” here means only that the first hour back closed inside the zone. The question that matters is what price did after a breaker held, compared with any other hour, and what trading it would have paid after costs. Breakers are rare enough that answering it needs every market in the record. We have not counted that yet.

Breaker block questions

What is a breaker block in trading?

An order block that price closed through. A failed bullish block becomes a bearish breaker (resistance); a failed bearish block becomes a bullish breaker (support).

Breaker block vs order block: what is the difference?

An order block is the last opposite candle before a break of structure, read in the direction of the break. A breaker is the same zone after price closed through it, read in the opposite direction. Every breaker starts as an order block.

Bullish or bearish breaker?

A bullish breaker comes from a failed bearish order block: price closed above it, and the zone is then watched as support. A bearish breaker comes from a failed bullish order block and is watched as resistance.

Do breaker blocks work in crypto?

Not counted yet, and rare: see above. The closest ICT idea EdgeDepth has counted end to end, with a trade test after costs, is the liquidity sweep.

Which timeframe should I use?

This page uses one-hour candles so the rule is exact. Traders mark breakers on every timeframe; lower timeframes give more of them, each covering a smaller move.
