Pipe bottoms are okay performers in a bull market when performance is measured on the weekly scale. However, compared against other patterns on the same scale, they place last. Pipes have a small break even failure rate and high average rise. Discovered by Thomas Bulkowski in 1998.

Pipe Bottom: Important Bull Market Results

Overall performance rank: 3 (last) of 3, weekly scale
Break even failure rate: 8%
Average rise: 54%
Percentage meeting price target: 77%

The above numbers are based on more than 8,800 perfect trades. See the glossary for definitions.

Pipe Bottom: Identification Guidelines

CharacteristicDiscussion
Weekly chartPipes appear on the daily scale but the ones on the weekly charts perform better. Use the weekly chart.
Price trendUsually downward leading to the pattern.
ShapeTwin and adjacent downward spikes. On a bar chart, the two price bars look like spikes. On a candlestick chart, the candles can be any shape (from doji to Marubozu). In other words, don't let the term spike mislead you.
OverlapThe 2 weeks often have a large price overlap but need not bottom at the same price. The bottom price variation is 1%.
VolumeMost pipes show above average volume on one or both spikes.
ObviousThe pipe should stand-alone and be obvious on the chart. The spike should clear the surrounding price action.
DowntrendsThe best performing pipes appear at the end of downtrends.
ConfirmationThe pattern confirms (becomes a valid pattern) when price closes above the highest high in the pattern.

Pipe Bottom: Trading Tips

Trading TacticExplanation Pipe bottom measure rule
The Measure Rule

Pipe bottom spike Spike

Measure ruleCompute the height from the taller of the two spikes to the lower of the two (the AB distance in the Measure Rule figure to the right) then multiply by the above 'percentage meeting price target.' Add the difference to the higher of the two (A) to get a price target, C.
BuyBuy when price closes above the higher of the two spikes. I show that as A in the Measure Rule figure to the right.
TrendsPipes with a short-term (up to 3 months) downtrend leading to the pipe perform best.
Uneven lowsPipes with uneven lows tend to perform better than do those with spikes that bottom at the same price. The Spike figure shows an example of spikes with uneven lows (spike B is lower than spike A).
Yearly lowPipes within a third of the yearly low perform best.
VolumeHeavy left spike volume when compared to the right suggests better performance.
StopIf price closes below the lower of the two spikes, then close out your position.

Pipe Bottom: Example

Pipe bottom chart pattern example

The above figure shows an example of a pipe bottom chart pattern. This pipe bottom appears as part of a retrace in an uptrend, signaling higher prices ahead. The retrace begins at A and bottoms at the pipe then price begins its recovery. Shown on the weekly scale.

Pipe Bottom: Target Exit, Stock Performance

Using the ACMR figure, for trading I place a stop loss order a penny below the lower of the two pipe spikes, and a buy stop a penny above the top of the highest pipe spike. The target is the difference between the highest and lowest price in the pipe, multiplied by two, and added to the highest price in the pattern. I show the approximate locations of each on the chart. If a buy and sell order happens on the same day, I don't take the trade. That's a flaw with the test, but using the daily chart, I can't tell if the sell occurred before the buy (or not).

For a more detailed explanation of the method I used to test the pattern, see the link.

Pipes in uptrend substantially outperform the benchmark ($377.47 versus $174.53), but should be avoided in downtrends.

Pipe Bottom: Target Exit, Crypto Performance

I found only two trades in each direction, which is too few to report on.
