Breaker Blocks

Breaker Blocks Trading

A discretionary label for a candle zone that is crossed and later tested from the opposite side. It is a support/resistance hypothesis, not evidence of trapped or institutional orders.

Identification

Bullish Breaker (Failed Bearish OB)

1. Bearish order block forms
2. Price returns and breaks through the OB aggressively (displacement)
3. The broken OB flips to support (bullish breaker)
4. Trade longs when price returns to this zone

Bearish Breaker (Failed Bullish OB)

1. Bullish order block forms
2. Price returns and breaks through the OB aggressively (displacement)
3. The broken OB flips to resistance (bearish breaker)
4. Trade shorts when price returns to this zone

Testable Features

• Normalize break distance and speed by ATR and elapsed bars.
• Define the zone from exact OHLC fields and an objective swing rule.
• Record overlap with an FVG, higher-timeframe state, and retest count as candidate features—not quality grades.
• Use a closed-bar crossing buffer and prevent future bars from changing the original label.

Workflow

1. Find a failed order block using candle data:

   get_candles_around_date(symbol=<symbol>, exchange=<exchange>, interval=<interval>, date=<date>)
   

2. Confirm the break with the predeclared swing and close-plus-buffer rule
3. Mark the breaker zone using draw_chart_analysis with demand (bullish) or supply (bearish)
4. Wait for price to return to the zone from the opposite side
5. Enter with LTF confirmation (structure shift or rejection)
6. Stop loss beyond the breaker zone
7. Target next liquidity level or POI

Evidence and Validation

• Treat the setup as a testable hypothesis, not a prediction. Define thresholds, entry, invalidation, and exit before evaluating outcomes.
• Calibrate on the same instrument, venue, session, and timeframe. Use closed candles and a held-out or walk-forward sample; record every variant tried.
• Include spread, fees, slippage, borrow or funding, partial fills, and latency. Reject the setup when net expectancy is not positive or depends on one narrow parameter.
• Return observed inputs, missing data, cost assumptions, entry, invalidation, exit, and a valid, watch, or no-trade status.
• Research basis: Treat breaker blocks as a discretionary support/resistance labeling convention. Lo, Mamaysky & Wang supports objective pattern testing, not claims about hidden institutional intent.

Key Rules

• Do not claim knowledge of trapped traders or hidden order intent from candles alone.
• Define displacement in ATR and bars before testing.
• Test first and later retests separately rather than assuming only the first works.
• Return no trade when swing, break, retest, liquidity, or cost definitions are incomplete.
