Indicator Reference — Reversal Bars
Barky’s Diagonal Entry Model
Barky’s Reversal Bar system identifies exhaustion at setup highs and lows — marking the candle where a flush has overextended and the conditions for a high-probability knife catch are in place.
ECD Snap – Reversal Candle – Rejection Wick – Knife Catch
OVERVIEW
Reversal Bars
When price breaks a setup high or low, the ECD Snap fires — alerting that a false break has occurred and a backtest trade has to set up to confirm the break. The indicator watches for a trade opportunity, highlighting a Reversal Bar if it forms: a candle with a small body that closed near the extreme, with a long rejection wick pointing back toward the EMA9. This two-step sequence — ECD Snap then Reversal Bar — is Barky’s ECD-RT. A knife catch concept on any timeframe, but also highlights the formation of a lower timeframe Diagonal Entry Model.
TWO COMPONENTS
ECD-Snap False Break Alert
Price looks above a setup high or low. The ECD Snap fires, alerting that a price is attempting continuation. This initiates the search for a Reversal Bar on the current or next candle (candle 2 or candle 3 reversal).
Reversal Bar Exhaustion Candle
A shaded box draws around the candle body if size criteria are met. The candle is highlighted by a Reversal Candle label.
●
Knife Catch Bars — Without exception, ‘knife catch’ reversal candles have small bodies near the extreme with a long rejection wick toward the EMA9 — the body size confirms the wick defines the risk.
●
LTF DEM Alert — After the ECD Snap alert, the first candle with reversal bar highlights the moment to zoom in for the related lower timeframe Diagonal Entry Model setup.
ANATOMY OF AN A+ REVERSAL CANDLE
Knife Catch RT · What to Look For
A+ REVERSAL BARS
BODY SIZE
Small — the smaller the better.
A tiny body signals that buyers and sellers reached equilibrium near the extreme. A large body reduces signal quality significantly.
—
BODY LOCATION
Has to Form Close to the Extreme
For an A+ signal and justifiable risk/reward, the reversal bar must form close to the setup low (on breakdowns) or setup high (on breakouts) — not mid-range. The body should be near the wick extreme, not stranded in the middle of the candle.
—
REJECTION WICK
Long — the longer the better.
The wick represents the failed attempt to extend the flush — the longer it is relative to the body, the stronger the reversal signal.
—
WICK DIRECTION
Toward the EMA9
On a breakdown: wick points upward toward EMA9. On a breakout: wick points downward toward EMA9. The wick must be pointing back into the range, not away from it.
—
NEXT CANDLE OPEN
Trade A+ Setups Direct – or Zoom In for LTF DEM
For entry, the following candle should open near the close of the reversal bar, then first move toward the extreme, even better if it sweeps the extreme, then push back through the open price of the reversal bar.
When a Reversal Bar forms, the lower timeframe Diagonal Entry Model setup is always there.
WORK FLOW – STEP BY STEP
From ECD Snap to Lower Timeframe Diagonal Entry Model
Day Trades · H1 → M5
H1 SIGNALS / M5 RISK
01 – H1
ECD Snap Alert on H1
Price breaks a setup high or low. The alert fires to indicate that a backtest trade opportunity has to form next.
—
02 – H1
Reversal Bar Forms on H1
Assess quality — small body near the extreme with a long wick is the A+ setup, but any qualifying Reversal Bar is a reason to zoom in.
—
03 – H1 → M5
Zoom to M5 for Entry Model
The H1 reversal bar maps to an M5 EMA50 Wedge. Zoom in to M5 and locate the M5 DEM into support or resistance to define risk and direction.
—
04 – M5 ENTRY
Enter M5 DEM Trigger
Stop beyond the M5 DEM entry candle or the last M5 failed swing (HL / LH) before the break. Measure 1R expansion on H1 and take breakout partials there. If H1 EMA9/21 are reclaimed, look for a Control Bar setup to confirm continuation and trail H1 EMA21.
Day Trades · H4 → H1
H4 SIGNALS / H1 RISK
01 – H4
ECD Snap Alert on H4
Price breaks a setup high or low. The alert fires to indicate that a backtest trade opportunity has to form next.
—
02 – H4
Reversal Bar Forms on H4
Assess quality — small body near the extreme with a long wick is the A+ setup, but any qualifying Reversal Bar is a reason to zoom in.
—
03 – H4 → H1
Zoom to H1 for Entry Model
The H4 reversal bar maps to an H1 EMA50 Wedge. Zoom in to H1 and locate the H1 DEM into support or resistance to define risk and direction.
—
04 – H1 ENTRY
Enter H1 DEM Trigger
Stop beyond the H1 DEM entry candle or the last H1 failed swing (HL / LH) before the break. Measure 1R expansion on H4 and take breakout partials there. If H4 EMA9/21 are reclaimed, look for a Control Bar setup to confirm continuation, an add, begin and trail H1 EMA21.
SIGNAL REFERENCE
↗
Risk management. Reversal triggers invalidate when a new low (or high) is made. To play for a swing, the stop goes beyond the exhaustion wick extreme. Taking partial profits for 1R gets risk free runners long and protects capital. The EMA9 has to be reclaimed and the Control bar setup has to form. Never widen the stop to accommodate noise beyond the wick.
↻
The rejection initiates the DEM. After the ECD-RT bounce reaches the EMA9 or the opposing setup boundary and is rejected, the EMA9 trend has been neutralised and the Diagonal Entry Model has to form — watch for the 5/12 Curl and the wedge formation to form, then wait for the trap to define risk and enter.
◐
Context is everything. An ECD-RT without a pre-planned level, key zone, or higher timeframe edge is just scalps before setup formation. Context for a bigger reversal is only when price sweeps into a higher timeframe zone or level where a bigger reaction should be anticipated.
!
This is a scalp first, reversal second. The primary target is the EMA9 and the breakdown backtest. In most cases, price will reject at that level — anticipate it and take profits. Only in specific higher timeframe contexts does this setup turn into a larger reversal.
TIPS
●
The LTF DEM confirms the setup. When a Reversal Bar forms, the lower timeframe Diagonal Entry Model setup is always there. When trading the setup on the bar direct – without zooming in, the quick push back to the wick extreme guarantees that the lower timeframe DEM meets the entry requirement: a failed swing or a failed break.
●
The first Reversal Bar after an ECD Snap is always the invitation to zoom in. Whether or not it is an A+ knife catch, drop to the LTF immediately and assess whether a DEM is forming. The HTF reversal bar is the reference — the LTF confirms breakout or breakdown, allowing a precise entry and a tighter stop.
●
The smaller the body relative to the wick, the stronger the setup. A doji or near-doji at a key level is the highest quality version. If the body takes up more than half the candle range, reassess whether the rejection is genuine (zoom in to inspect the LTF setup).
●
Always anticipate rejection at the EMA9 backtest. The bounce target is the EMA9 (breakdown backtest / breakout backtest). When price arrives there, a CB or BT/RT signal will forms — signalling the continuation of the underlying trend, or confirming a reversal. Take profits at the EMA9 unless the higher timeframe context justifies holding.

Toggles the shaded body box drawn around qualifying reversal candles. Disabling hides the box but keeps the label if enabled separately.
SHOW REVERSAL CANDLE LABEL
Toggles the “Reversal Candle” label. Can be shown independently of the body box. Abbreviated to “RT” when Use Abbreviated Labels is active.
SHOW ECD SNAP LABELS

Controls how many historical labels remain on chart. Set to 1 to show only the current label — the ECD Snap disappears when the Reversal Candle plots, keeping the chart clean.
REVERSAL BAR TOLERANCE
Counter Trend Body Size Cap
ATR-based tolerance for detecting a reversal candles that oppose the trend direction. Higher values allow candles with larger opposing body to qualify.
REVERSAL BAR TOLERANCE
Trend Direction Body Size Cap
ATR-based tolerance for detecting a reversal candles in the direction of the trend. Higher values allow larger ‘with-trend’ bodies to quality.
