Order Blocks & Breaker Blocks

Order blocks (classic framing)

Order blocks (OBs) are often described as areas where large participants accumulated or distributed size — zones that can later act as support/resistance. They are zones, not single prices.

Technically: order = buy/sell interest; block = a range of prices, not one tick.

Why they can matter: large participants rarely execute everything at one price; activity prints a zone on the chart.

Four pillars often used to qualify an OB:

  1. Liquidity grab (often a wick / stop run)
  2. Candle body (conviction / aggression)
  3. BOS (break of structure — context-dependent definition)
  4. Imbalance (inefficiency / FVG-style gap — see AMT notes)

1. Liquidity grab

A liquidity grab is a fast move through a level where stops and resting orders cluster. It often shows as a wick. These often relate to areas where participants expect supply/demand — consistent with auction/liquidity ideas. Often discussed alongside FVGs.

2. Candle body

Stronger OBs often involve a large body (aggressive impulse). A doji can still be "valid" in some systems, but momentum/aggression is weaker → easier to melt through.

3. BOS

Many frameworks require a break of structure to validate the OB. No BOS, no OB is a common rule-of-thumb.

4. Imbalance

Inefficiency must often remain open (third candle doesn't fully wick-fill the gap). If the gap is filled, the inefficiency is invalidated for that OB read.

5. Mitigation

  • Mitigated OB: price returned and filled/worked the zone — resting orders may be largely executed → less "unfilled" edge.
  • Unmitigated OB: price has not fully revisited — some models treat this as higher priority for future reaction.

Breaker blocks

Breaker blocks = failed OBs that flip role (supply becomes demand or vice versa), still following similar rules: liquidity sweep + BOS context matters.

Quick mental model: a bearish OB gets fully violated; later, that same area can behave as demand (bullish breaker) if price reclaims and holds.

Double / triple breakers

A zone can fail once and still matter — it may flip into a breaker. Price can return multiple times, each time reinforcing a role change (double/triple breaker).

Risk: you cannot know with certainty which touch will "hold." Position sizing and invalidation rules matter. Violent pierces through a zone (vs many small taps) are emphasized in the original notes.
