Break even failure rate for up/down breakouts: 15%/28%
Average rise/decline: 43%/14%
Throwback/pullback rate: 68%/63%
Percentage meeting price target for up/down breakouts: 67%/40%
The above numbers are based on 551 samples for upward breakouts and 455 for downward breakouts. See the glossary for definitions.
Broadening Formations, Right-Angled and Ascending: Identification Guidelines
Characteristic | Discussion |
Price trend | Can be up (74% have a rising price trend) leading to the pattern. |
Shape | A megaphone tilted up with the bottom horizontal. |
Trendlines | The bottom trendline is horizontal, the top one slopes upward. |
Touches | At least five touches total, three peaks or three valleys should touch the associated trend line with two or more touches of the other trendline.
Ideally, the second of three touches will touch (instead of coming 'close' to) the trendline. |
Volume | Trends upward 62% to 63% of the time. |
Breakout | Upward 55% of the time. |

Broadening Formations, Right-Angled and Ascending: Trading Tips
Trading Tactic | Explanation |
The Measure Rule
|
Measure rule | Compute the height from the highest peak (point A in the Measure Rule figure to the right)
to the horizontal trendline (B) and multiply it by the above "percentage meeting price target" (see Important Bull Market Results). Add the result to the highest peak (A,
upward breakouts) or subtract it from the horizontal trendline (B, downward breakouts) to get the price target (C). |
Intraformation trade | Buy at the horizontal trendline when price starts rising and sell or sell short once price turns at the top trendline. |
Buy at 3rd touch | When price touches the horizontal trendline for the third time and begins rising, buy. |
Partial rise | A partial rise works 61% of the time. |
Partial decline | A partial decline works 80% of the time. |
Price trend | The best performing patterns are those with a short-term (less than three months) rise leading to the pattern. |
Yearly high, low | Downward and upward breakouts perform best when the breakout is within a third of the yearly low. |
Volume trend | A downward volume trend results in the best postbreakout performance. |
Throwbacks and pullbacks | Throwbacks and pullbacks
hurt postbreakout performance. |
Height, width | Tall patterns perform better than short ones.
Wide patterns (both breakout directions) perform well. |

Broadening Formations, Right-Angled and Ascending: Time Performance
Bull Market Performance Over Decades
Breakout Direction | 1990s | 2000s | 2010s |
Up (average) | 41% | 50% | 36% |
Down (average) | 16% | 13% | 14% |
The above table shows the performance of right-angled ascending broadening top chart patterns in bull markets over the last three decades.
Upward breakouts did best in the 2000s but worst in the 2010s.
Downward breakouts outperformed in the 1990s but didn't vary much among the decades.
Broadening Formations, Right-Angled and Ascending: Example
The above figure shows an example of a right-angled and ascending broadening formation. A strong
advance begins at point D and that leads to the right-angled and ascending broadening
formation. Price bounces between two diverging trendlines before it closes outside the bottom trendline at
A. This marks the downward breakout. Price recovers and busts the pattern at
C when price moves above the top of the chart pattern. A throwback completes at
B and price climbs thereafter.
Broadening Formations, Right-Angled and Ascending: Lessons
Below are some of the lessons I learned from trading these patterns over the decades. You can use the Patternz simulator to reproduce the charts in full.
I downloaded the data from Tiingo but not all stocks currently trade.
I present the information in slider format, so be sure to click the left or right arrows to view another slide.
Please note: These tips are for swing traders or even scalpers, those who want to trade from low to high or skim off a few bucks, and not for buy-and-hold investors.
Lessons Summary
- Slide 1. Win: RABFA appears near a new high, pushes above overhead resistance (if any) and soars.
- Slide 2. Win: Pushing through overhead resistance is profitable.
- Slide 3. Avoid: Overhead resistance doomed this trade.
- Slide 4. Win: Overhead resistance limits the potential profit...for a time.
- Slide 5. Avoid: A multipeak pattern shows the danger of overhead resistance.
- Slide 6. Avoid: A fast rise is suspect in a busted upward breakout.
- Slide 7. Avoid: Beware the fast rise.
- Slide 8. Win: A long uptrend doesn't bode well for this RABFA but no buy signal occurs.
- Slide 9. Win: A busted downward breakout sees price soar.
- Slide 10. Win: A potential double top meant a skipped winner.
1 / 10
AMGN (Amgen, 4 June 2014 to 7 July 2014). Let's start with a winner. This chart pattern is unusual because it ignores the long term uptrend like that shown here (more of it is off the chart at the start).
It pushes through overhead resistance setup by the broadening top and continues rising.
I've seen this behavior a lot where the RABFA is at the top of the chart and all it has to do is breakout to new territory, a short distance away, to be free of overhead resistance. The stock then soars.
There are examples where that's not true, but it seems to be a reliable buy signal.
Next: Pushing through overhead resistance is profitable.
2 / 10
AEP (American Electric Power, 17 August 2011 to 1 September 2011). In this example, the stock eventually pushes above resistance. When that happens, the move can be profitable.
A longer-term chart shows the stock climbing into the 60s, but it was a bumpy ride.
Next: Overhead resistance doomed this trade.
3 / 10
ABDE (Adobe 2/9/12 to 3/2/12). In this example of a failed trade, the chart pattern neared the bottom of overhead resistance setup by prior peaks and valleys (between the two horizontal red lines).
The chart pattern broke out upward but soon reversed and dropped below the bottom of the chart pattern, where a stop loss order waited.
Next: Overhead resistance limits the potential profit...for a time.
4 / 10
AEL (American Equity Investment Life Holding from 29 September 2016 to 24 October 2016). The horizontal red line shows where I expected overhead resistance to stop an advance. With price sitting
at the top of the chart pattern (the RABFA), there wasn't a lot of room for growth. So I skipped the trade. The pattern broke out downward, reversed, and busted the downward breakout. Although it looks as if
the stock didn't rise far, the bust carried it to 28 (not shown).
Next: A multipeak pattern shows the danger of overhead resistance.
5 / 10
ADSK (Autodesk from 26 August 2014 to 19 September 2014). Here's an example of a multipeak pattern posing overhead resistance that stops an advance.
The triple top (blue circle) signals overhead resistance is present combined with the earlier peak (February 2014) presents a challenge that the stock can't overcome. The stock hits
resistance and reversed, busting the upward breakout.
Next: A fast rise is suspect in a busted upward breakout.
6 / 10
ARW (Arrow Electronics from 15 December 2016 to 25 January 17). A fast rise in the stock lead to a slowdown when the RABFA formed. An upward breakout didn't take the stock much higher at all before
it failed. This type of failure is hard to identify because what is meant by a 'fast rise'? Does a fast move actually cause price to retrace?
Next: Beware the fast rise.
7 / 10
ADBE (Adobe 9/27/16 to 10/24/2016). The tall gap is what I consider as part of a fast rise setup. It's a dangerous setup for a bullish trader. Price rises quickly going into the pattern and
often the breakout is downward. No buy signal triggers, so traders remain out of the stock. But you'll want to avoid the fast rise leading to the start of a chart pattern.
I show another example of the fast rise in the inset box in Amazon.com stock.
Next: A long uptrend doesn't bode well for this RABFA but no buy signal occurs.
8 / 10
ALK (Alaska Air from 19 June 2014 to 16 July 2014). This is another variation of the 'avoid the long uptrend' setup. In this case, the chart pattern appears after a long uptrend. In this case,
placing a buy stop a penny above the top of the chart pattern avoids buying this stock and suffering through the decline.
Next: A busted downward breakout sees price soar.
9 / 10
AGO (Assured Guaranty from 23 August 2016 to 8 September 2016). The RABFA broke out downward so a buy stop didn't trigger until the pattern busted the downward breakout. The price made a strong
push higher, piercing overhead resistance.
Next: A potential double top meant a skipped winner.
10 / 10
ACN (Accenture PLC, from 28 April 2015 to 11 May 2015). The RABFA formed and it looked like it might be part of a double top so I avoided the trade. However, the stock
climbed to a high of 105 before reversing and the potential double top never confirmed as a valid chart pattern (which means the stock didn't close below the lowest valley between the two peaks, so it wasn't
a valid double top).
The end.
