Megaphone Pattern

The megaphone pattern — also called an expanding triangle or broadening formation — is a chart structure defined by progressively wider price swings between two diverging trendlines. Unlike most chart patterns that signal compression and a pending breakout, the megaphone reflects escalating disagreement between buyers and sellers. It appears most often at market tops after extended trends, making it a high-value pattern for traders who spot reversals early.

How to Identify the Megaphone Pattern

1. Two higher highs and two lower lows — Draw an upper trendline connecting at least two rising peaks and a lower trendline connecting at least two falling troughs. Both lines must diverge, not converge.
2. Symmetrical divergence from origin — The upper trendline slopes upward at roughly 20-35 degrees; the lower trendline slopes downward at a similar angle. Asymmetric divergence (one line nearly flat) indicates a different pattern.
3. Expanding swing amplitude — Each successive high must exceed the prior high, and each successive low must undercut the prior low by at least 0.5% of price. Marginal new extremes weaken the pattern.
4. Five-touch structure — A valid tradeable megaphone has a minimum of five alternating touches: touch 1 and 3 and 5 on the upper boundary, touch 2 and 4 on the lower (or vice versa). Patterns with only three or four touches are forming, not complete.
5. Volume expansion — Volume tends to increase as the pattern matures, reflecting growing market disagreement. A fifth touch accompanied by a spike in volume at the boundary is a strong confirmation signal.

Entry Rules

1. Wait for the fifth touch — Only enter on the fifth alternating touch of a boundary trendline. Earlier entries lack statistical support; the pattern is still forming and can extend further before resolving.
2. Require a rejection candle — The fifth-touch candle must show a clear rejection: a pin bar, hammer, or engulfing candle whose close is back inside the pattern body. Volume on this candle should be at least 1.3x the 20-bar average.
3. Confirm higher-timeframe context — A megaphone touching its upper boundary directly into a weekly resistance zone gives a significantly stronger short setup than one forming in empty space. Always check one timeframe above.
4. Use a limit order at the boundary — Place a limit entry 2-5 pips inside the trendline rather than entering at market on the close. This reduces slippage on fast-moving boundary touches and improves the R:R slightly.

Exit Rules and Targets

1. Primary target: opposite boundary — The first profit objective is the opposing trendline at the projected price level at the time price is expected to arrive (accounting for the slope).
2. Secondary target: measured move — The full measured move equals the widest vertical spread of the pattern projected from the entry point. On a short from the upper boundary, subtract the full pattern width from the entry price.
3. Trail stop to midline — Once price crosses the midpoint between the two trendlines, move the stop to breakeven. If targeting the measured move, trail the stop to the last swing high on the way down.
4. Time-based exit — If price has not reached the midline within 15 bars on the entry timeframe, reassess. Stalling in the middle of the pattern often precedes a reversal back toward your entry.

Target Calculation: Measure the vertical distance between the upper and lower trendlines at the rightmost completed swing — this is the pattern width. Subtract this value from a short-entry price, or add it to a long-entry price, to get the measured-move target.

Stop Loss Placement

Place the stop 5-8 pips beyond the wick extreme of the rejection candle at the boundary. For a short entered at the upper trendline, the stop sits above the highest wick of the entry candle — not above the trendline itself, as that would inflate the risk unnecessarily. Because the stop is anchored just beyond the wick while the target spans the full pattern width, well-formed megaphone trades typically produce R:R ratios of 4:1 to 10:1 when targeting the opposite boundary. If the R:R falls below 2:1 after accounting for spread and slippage — because the pattern is too narrow or the entry is too far from the boundary — skip the trade.

Practical Example

On the daily chart of GBP/USD, a megaphone pattern forms over 22 trading days. Price rallies from 1.2720 to 1.2840 (touch 1, upper boundary), pulls back to 1.2690 (touch 2, lower boundary), rallies to 1.2870 (touch 3, upper boundary), drops to 1.2650 (touch 4, lower boundary), then rallies to 1.2910 (touch 5, upper boundary). At touch 5, a bearish engulfing candle appears on volume 1.6x the 20-bar average, with daily RSI showing bearish divergence.

Entry: short at 1.2905 (5 pips inside the boundary via limit). Rejection candle wick high: 1.2917. Stop: 1.2930 (13 pips above the wick, with a 5-pip buffer for spread). Risk: 25 pips. Pattern width at the rightmost point: 1.2910 − 1.2650 = 260 pips. Primary target: lower boundary at approximately 1.2650 (255 pips reward). Measured-move secondary target: 1.2905 − 0.0260 = 1.2645.

R:R to primary target: 255 pips reward ÷ 25 pips risk = 10.2:1.

On a $10,000 account risking 1% ($100), position size = $100 ÷ (25 pips × $1 per pip per mini lot) = 4 mini lots. If price reaches the primary target at 1.2650, profit = 255 pips × $1 × 4 mini lots = $1,020 — a 10.2R outcome. This is the structural reason megaphone fades are attractive: the stop is anchored just beyond the rejection wick while the target spans the full pattern width.

Best Timeframes for the Megaphone Pattern

The 4-hour and daily charts produce the highest-probability megaphone setups in forex, where five well-defined touches typically develop over 10-40 bars. The 1-hour chart can work during the London session when liquidity is high, but intraday noise increases false boundary touches significantly. On the weekly chart, megaphones are rare but powerful — they often mark major market tops and can produce multi-hundred pip moves toward the lower boundary. The estimated 55–62% success rate applies to daily-chart setups with volume confirmation based on discretionary backtesting; intraday setups tend to perform closer to 50–54% without additional filtering, and both figures should be treated as practitioner estimates rather than sourced statistics.

Common Mistakes

1. Entering on the third or fourth touch — Traders anticipate the pattern before it’s confirmed and get stopped out repeatedly. The fifth touch is the only statistically validated entry point in the structure.
2. Fading instead of trading the breakout — When a megaphone breaks cleanly beyond a boundary on high volume, it signals a strong directional move. Traders who blindly fade every touch miss legitimate breakout setups.
3. Ignoring higher-timeframe context — A megaphone whose upper boundary aligns with a daily supply zone or a Fibonacci retracement level has significantly more edge than one in open space. Always layer context.
4. Placing the stop beyond the full pattern — Some traders set stops outside the entire pattern width “to avoid being stopped out.” This eliminates the R:R advantage entirely. Stop placement belongs just beyond the rejection candle’s wick.
5. Conflating the megaphone with a diamond top — A diamond pattern forms when a broadening phase transitions into a contracting phase, creating a diamond shape. A megaphone only expands — the two patterns require different trade management approaches.

How to Journal Megaphone Pattern Trades

Journal Field	What to Record	Why It Matters
Touch Number	3rd, 4th, or 5th touch at entry	Isolate whether later touches outperform
Rejection Candle Type	Pin bar, engulfing, doji	Identify which rejection signal is most reliable
Volume at Touch	Relative volume vs 20-bar average (e.g., 1.4x)	Filter low-conviction boundary tests
HTF Context	Key level alignment (support/resistance, Fibonacci)	Measure impact of contextual confluence
Pattern Width	Vertical spread in pips at rightmost point	Correlate pattern size to outcome magnitude
Target Reached	Primary (opposite boundary) / Secondary (measured move) / Neither	Track how far price travels after entry
Trade Duration	Bars held on entry timeframe	Understand how long megaphone trades typically run

After logging 50 or more megaphone trades, the pattern data will show whether your edge is concentrated in fifth-touch entries at key HTF levels, or whether any touch at the boundary works equally well for your execution style. PipJournal’s tagging and filtering system lets you filter all trades tagged “megaphone” by “touch number” or “HTF context” to surface exactly these breakdowns — turning 50 trades of raw data into a refined, personalized setup rule set.

Related patterns worth studying alongside the megaphone include the broadening formation, which covers asymmetric variants, and the diamond pattern, which adds a contracting phase. For stop and entry mechanics, the rising and falling wedge shares overlapping geometry and trade management principles. The double top is a simpler reversal structure that often forms as a megaphone’s upper boundary gets tested and rejected.
