Engulfing Failed Zone [8 Types]
Engulfing Failed Zone [8 Types]
Most engulfing tools show you where a pattern formed. This one shows you where it broke.
The script finds confirmed engulfing patterns and then keeps watching them. When price later
closes back through the far side of the pattern's Base candle, the pattern is invalidated and
the area it occupied is drawn as a failed zone, from the Base candle to the exact candle that
broke it.
A failed pattern is not noise. It marks a level where one side committed, was proven wrong,
and left an area behind that price often reacts to again.
WHAT MAKES THIS DIFFERENT
1. It tracks invalidation, not formation.
A normal engulfing indicator stops working the moment the pattern prints. This script treats
the pattern as an open structure and follows it forward until something breaks it. Only the
broken ones are drawn, so the chart shows failures rather than signals.
2. Failure is defined by the close, not by a wick.
A candle may spike through the Base candle and recover. That is not a failure here. The
breaking candle has to CLOSE beyond the level, and it has to be the correct color: a Red
candle closing below the Base Low breaks a Buy Engulfing, a Green candle closing above the
Base High breaks a Sell Engulfing.
3. Failed zones are sorted into eight types, not two.
The failure inherits the identity of the pattern that failed. A liquidity sweep engulfing that
fails is a different event from a plain two candle engulfing that fails, and the script keeps
them separate so you can study or filter them independently.
4. Only the first failure is drawn.
Once a pattern breaks, it is done. Later candles closing through the same level are not drawn
again, which keeps the chart readable instead of stacking boxes on one level.
THE PATTERNS BEING TRACKED
A candle is Green when close is greater than open, Red when close is less than open, and a
Doji when close equals open. A Doji is neither. Only fully closed candles are read, and the
running candle is never used.
Regular engulfing (2 candles)
R Buy EG
Red Base candle, and the very next candle is Green and closes above the Base candle's High.
R Sell EG
Green Base candle, and the very next candle is Red and closes below the Base candle's Low.
E-Regular engulfing (3 or more candles)
ER Buy EG
Red Base candle followed by a run of consecutive Green candles. The run must contain at least
2 Green candles, and confirmation happens when one of them closes above the Base candle's
High. A single Red candle appearing before confirmation cancels the run. Doji candles are
skipped: they neither count toward the run nor break it.
ER Sell EG
Green Base candle followed by a run of at least 2 consecutive Red candles, one of which closes
below the Base candle's Low. A single Green candle cancels the run. Doji candles are skipped.
If the very first candle after the Base already closes through it, that is by definition a
Regular pattern, so E-Regular requires the second candle or later to break the level. One Base
candle can therefore never produce both a Regular and an E-Regular pattern.
Type 1: the same four patterns plus a liquidity sweep
Type 1 adds one requirement. Before the close breaks through one side of the Base candle,
price must have traded through the opposite side.
T1 R Buy EG
An R Buy EG where the Confirm candle's Low is at or below the Base candle's Low.
T1 R Sell EG
An R Sell EG where the Confirm candle's High is at or above the Base candle's High.
T1 ER Buy EG
An ER Buy EG where at least one Green candle in the run has a Low at or below the Base
candle's Low. Any candle of the run qualifies, including the Confirm candle itself.
T1 ER Sell EG
An ER Sell EG where at least one Red candle in the run has a High at or above the Base
candle's High. Any candle of the run qualifies, including the Confirm candle itself.
The sweep is always measured against the Base candle, never against another candle in the run.
WHAT COUNTS AS A FAILURE
After a pattern confirms, the script scans forward one candle at a time.
A Buy Engulfing fails when a Red candle closes strictly below the Base candle's Low.
A Sell Engulfing fails when a Green candle closes strictly above the Base candle's High.
The scan begins on the candle after the Confirm candle, so a pattern is never judged by its
own confirmation. The first candle that meets the condition becomes the Failure candle, and
the zone is drawn from the Base candle across to it. Nothing is drawn for patterns that are
still intact.
That gives eight failed zone types in total: R Buy EG Failed, R Sell EG Failed, ER Buy EG
Failed, ER Sell EG Failed, and the four Type 1 versions of the same.
READING THE CHART
Each failed pattern draws a rectangle covering the Base candle's full High to Low range,
stretched horizontally from the Base candle to the candle that broke it.
Colors follow the OUTCOME, not the original direction. This is worth reading twice:
- A Buy Engulfing that failed is drawn in the bearish color. The buyers committed and lost, so
the area above is now resistance, and its label sits above the zone.
- A Sell Engulfing that failed is drawn in the bullish color. The sellers committed and lost,
so the area is now support, and its label sits below the zone.
In other words the zone is colored by who is in control after the failure, which is the
information you actually trade from.
The border tells you which pattern failed:
Type 1 zones are also filled more solidly, so the stronger patterns stand out when several
zones sit close together.
A separate line marks the broken edge of the Base candle: the Low for a failed Buy Engulfing,
the High for a failed Sell Engulfing. This shows at a glance which side of the pattern gave
way, and it is the level price most often returns to.
Each zone carries a label with its pattern tag, pointing at its own zone, so it is always
clear which label belongs to which rectangle.
A summary table in the corner counts how many of each type were found in the current scan
window, split into Buy EG and Sell EG columns. The counts include types that are currently
hidden, so the table always reflects what the market actually printed rather than what is
switched on.
SETTINGS
Scan
- Scan Length: how many closed candles are scanned backwards from the latest bar. The running
candle is always excluded.
Pattern Types
- An individual on and off switch for each of the eight failed zone types.
Zone Style
- Buy EG Failed Zone and Sell EG Failed Zone: the two zone colors. Defaults follow the outcome
logic described above.
- Zone Transparency: fill transparency of a plain Regular or E-Regular failed zone.
- Type 1 Extra Opacity: how much more solid Type 1 zones are filled compared to the value
above.
- Highlight Broken Edge, and its color: marks the side of the Base candle price closed
through.
Labels
- Show Labels, Label Size, and Label Distance from Zone as a percentage of the Base candle
height. Increase the distance on noisy charts so labels clear the candles.
Summary Table
- Show, position, and size of the corner table.
ALERTS
Eight alert conditions are available, one per failed zone type:
R Buy EG Failed, R Sell EG Failed, T1 R Buy EG Failed, T1 R Sell EG Failed, ER Buy EG Failed,
ER Sell EG Failed, T1 ER Buy EG Failed, T1 ER Sell EG Failed.
An alert fires on the candle that completes the failure. Each message carries the pattern tag,
the symbol, the timeframe and the closing price. The script also sends the same messages
through the alert function, so the "Any alert() function call" alert type can deliver every
failure through a single alert.
All alerts are evaluated only after a candle has fully closed.
Internally, every confirmed engulfing is held in a list and each closed candle is checked
against that list. This is what allows a failure to be reported the moment it happens, without
rescanning the whole history on every bar.
REPAINTING
This script does not repaint.
- Detection reads confirmed candles only. The scan starts one bar behind the latest bar, so
the candle that is still forming is never part of any calculation.
- Every alert signal is written so that it can only become true once a candle has finished.
Price moving inside an open candle cannot make a signal appear and then disappear.
- Zones are rebuilt on the last bar using confirmed history. A drawn zone does not move,
change color or change type afterwards. It only leaves the chart when it falls outside the
Scan Length window.
When you create an alert, TradingView may show a caution banner saying the indicator can
repaint. That banner appears automatically for any script that uses the built in bar state
variables, no matter how they are used, because the platform cannot check the intent behind
them. This script uses them for the opposite purpose: one of them is what restricts every
signal to bar close, and the other is what redraws the zones efficiently on the final bar.
Choosing "Once Per Bar Close" when creating the alert is still recommended.
NOTES AND LIMITATIONS
- Nothing is drawn for a pattern that has not failed. An empty chart means the engulfing
patterns in that window are all still intact, which is information in itself.
- Increasing Scan Length raises the number of drawing objects. TradingView caps these at 500
boxes, 500 labels and 500 lines, and the oldest objects are dropped once a cap is reached.
The default value is chosen to stay well inside those limits on normal charts.
- A very short Scan Length can hide zones whose Base candle sits outside the window even
though the failure is recent. If failures seem to be missing, raise the Scan Length.
- For alerts, the number of patterns tracked at once is capped, and the oldest are released
first. In practice patterns fail or age out long before this matters.
- Detection is purely structural. It reports where a pattern broke and nothing more. It does
not rank failures by quality, measure what happened afterwards, or produce entries, targets
or stops.
- Doji candles are treated as neutral by design. They never act as a Base candle and never
break an E-Regular run. On symbols and timeframes that print many Doji candles this makes
runs slightly more tolerant than a strict same color rule would be.
HOW TO USE IT
A failed engulfing zone marks a level where one side of the market committed and was proven
wrong. Traders commonly watch these areas for:
- Broken supply and demand zones that price returns to and respects from the other side
- Areas where a reversal attempt was flushed out before the move continued
- Momentum shifts, since a failed reversal often precedes a strong continuation
Type 1 failed zones are worth separating out. There the pattern first grabbed liquidity, then
confirmed, and then still failed, which is a different story from a clean pattern simply being
overrun.
These zones are reference areas, not entry signals on their own. Use them alongside higher
timeframe structure, your own support and resistance mapping, and proper risk management.
DISCLAIMER
This indicator is a pattern detection tool. It is not financial advice and it makes no claim
about profitability. Trading involves risk. Always apply your own analysis and risk management.

THE PATTERNS BEING TRACKED
A candle is Green when close is greater than open, Red when close is less than open, and a
Doji when close equals open. A Doji is neither. Only fully closed candles are read, and the
running candle is never used.
Regular engulfing (2 candles)
R Buy EG
Red Base candle, and the very next candle is Green and closes above the Base candle's High.
R Sell EG
Green Base candle, and the very next candle is Red and closes below the Base candle's Low.
E-Regular engulfing (3 or more candles)
ER Buy EG
Red Base candle followed by a run of consecutive Green candles. The run must contain at least
2 Green candles, and confirmation happens when one of them closes above the Base candle's
High. A single Red candle appearing before confirmation cancels the run. Doji candles are
skipped: they neither count toward the run nor break it.
ER Sell EG
Green Base candle followed by a run of at least 2 consecutive Red candles, one of which closes
below the Base candle's Low. A single Green candle cancels the run. Doji candles are skipped.
If the very first candle after the Base already closes through it, that is by definition a
Regular pattern, so E-Regular requires the second candle or later to break the level. One Base
candle can therefore never produce both a Regular and an E-Regular pattern.
Type 1: the same four patterns plus a liquidity sweep
Type 1 adds one requirement. Before the close breaks through one side of the Base candle,
price must have traded through the opposite side.
T1 R Buy EG
An R Buy EG where the Confirm candle's Low is at or below the Base candle's Low.
T1 R Sell EG
An R Sell EG where the Confirm candle's High is at or above the Base candle's High.
T1 ER Buy EG
An ER Buy EG where at least one Green candle in the run has a Low at or below the Base
candle's Low. Any candle of the run qualifies, including the Confirm candle itself.
T1 ER Sell EG
An ER Sell EG where at least one Red candle in the run has a High at or above the Base
candle's High. Any candle of the run qualifies, including the Confirm candle itself.
The sweep is always measured against the Base candle, never against another candle in the run.
WHAT COUNTS AS A FAILURE
After a pattern confirms, the script scans forward one candle at a time.
A Buy Engulfing fails when a Red candle closes strictly below the Base candle's Low.
A Sell Engulfing fails when a Green candle closes strictly above the Base candle's High.
The scan begins on the candle after the Confirm candle, so a pattern is never judged by its
own confirmation. The first candle that meets the condition becomes the Failure candle, and
the zone is drawn from the Base candle across to it. Nothing is drawn for patterns that are

so the area is now support, and its label sits below the zone.
In other words the zone is colored by who is in control after the failure, which is the
information you actually trade from.
The border tells you which pattern failed:
- Solid border: a Regular pattern, confirmed by the very next candle
- Dashed border: an E-Regular pattern, confirmation was delayed over several candles
- Thin, softened border: a plain pattern, no sweep
- Thick, crisp border: Type 1, a liquidity sweep occurred before confirmation
Type 1 zones are also filled more solidly, so the stronger patterns stand out when several
zones sit close together.
A separate line marks the broken edge of the Base candle: the Low for a failed Buy Engulfing,
the High for a failed Sell Engulfing. This shows at a glance which side of the pattern gave
