Why Traders Should Avoid a Bear Flag Pattern Based On Data!

Bear Flags Do Not Provide a Good Opportunity for Traders, So Here's Why to Avoid Them.

A bear flag is a stock chart pattern in technical analysis that signals a potential continuation of a downtrend. The pattern resembles an upside-down flag on a pole. The pole is the initial drop in price, and the flag is a period of consolidation before another drop.

My analysis, research and testing stems from 25 years of trading experience and my Financial Technician Certification with the International Federation of Technical Analysts.

Traders make a big mistake when using this pattern. Be careful when trading bearish flags.

According to published research, the bear flag pattern has a low success rate of 45% and a price change of +9%. This means you are flipping a coin when trading this pattern, as the odds are not in your favor.

The high-tight bear flag is the only flag pattern you should trade, and I will show you how to trade it.

A lot has been written about trading bear flags, but academic research into flag patterns suggests that only the bullish, high-tight flag is successful.

Key Takeaways

  • The bear flag pattern looks like an inverse flag with a pole. The pole represents a sharp price decline, while the flag represents a price consolidation.
  • A bear flag is a continuation pattern, suggesting the price will decline after the consolidation phase.
  • All bear flags should be avoided as they have a low probability of success.
  • Only the high-tight bull flag is worth trading, as it is 85% successful with a 39% average price increase.

What Is a Bearish Flag Chart Pattern?

A bearish flag is a popular yet widely misunderstood technical analysis pattern characterized by a rapid downward price trend followed by parallel upslope consolidation in price. The price decrease resembles a flag pole, while the price consolidation is the flag.

The bear flag is a continuation pattern and occurs during a volatile price decrease, followed by an upward price consolidation. The price consolidation is caused by short traders who profited from the strong trend taking profits, and traders looking for bargains.

Most flag patterns slope in the opposite direction from the previous trend, but some can be horizontal and resemble a rectangle pattern.

How Reliable is a Bear Flag Pattern?

A high-tight bear flag chart pattern has an 85% success rate on an upside breakout, achieving an average 39% profit in a bear market. If the bear flag is loose, the failure rate is 55%, with only a gain of 9%.

High Tight Bear Flag 85% +39%

Why Most Bear Flag Patterns Fail

There are three flag patterns: the bull flag, the bear flag, and the high-tight bear flag. Research on 1,028 trades shows that standard loose flag patterns have a failure rate of 55%. In contrast, a high tight bull flag pattern has a success rate of 85% with an average gain of +39%.* Source

We need to learn to identify them to distinguish between reliably profitable high-tight flags and failing bull/bear flags (loose flags).

How to Identify a Bear Flag Pattern

The key element of a bear flag pattern is that it must occur after a strong price decrease, which acts as the pole. It must be preceded by at least three consecutive lower daily price closes. This is followed by a consolidation period, creating the flag part of the pattern.

The size and shape of the flag will vary, though usually, it is an upsloping channel or triangle with either two parallel trendlines or several lower highs and higher lows. The volume should diminish as the price consolidates, and the price should stay within the boundaries of the flag.

Once confirmed, a bearish breakout occurs when the stock closes below the lower trendline of the flag formation; this signals that buyers have capitulated and that more selling will follow. The pattern is usually complete with a target projection equal to the flagpole height added to the breakout level.

Above, we see a typical example of a bear flag failing. Instead of moving down, the price broke out upward and made a small new high before continuing further consolidation. The research shows bear flags only make a price move of 9% after a breakout. This is very low compared to inverse head and shoulders or double bottom patterns.

Identifying a Failing Loose Bear Flag

As defined in The Encyclopedia of Chart Patterns, a loose bear flag does not have an incredibly high/vertical flag pole, and the flag is not tight; it is loose. The chart above is an example of a loose flag.

Is the Bear Flag a Continuation Pattern?

The bear flag pattern is considered a continuation pattern, but the evidence shows it is both a continuation and a reversal pattern. The bear flag has an almost 50% chance of continuing or reversing the trend. Considering the average change after the breakout is only 9%, it is not worth trading this pattern.

How To Trade a Bear Flag Chart Pattern?

I would not advise trading a bear flag. The bear flag is an unreliable indicator, as evidenced by thousands of trades tested in the Encyclopedia of Chart Patterns.

When trading a bear flag chart pattern, traders should wait for the price to break out in either direction and place a tight stop loss because this pattern is unreliable.

It is important to note that traders should wait for a confirmed breakout above the flag pole peak before entering into a trade, as false breakouts above or below the flag pattern can often occur.

Traders should pay attention to volume when trading a bear flag chart pattern. Higher volume on the upward breakout is often considered a trend confirmation. This means traders should be vigilant and wait for higher volumes before entering a trade on any breakout situation.

The Psychology of Bear Flags

The psychology behind a bear flag chart pattern is similar to that of other continuation patterns, except that it is more volatile. It reflects the market’s strong commitment to continue moving in the same downward direction despite any short-term consolidation. Traders should know the previous trend and ensure it’s still intact before entering a trade.

This pattern typically appears in strongly trending markets, where the bull (buyers) and bears (sellers) battle each other back and forth until, eventually, the bears gain more strength.

The Bear Flag Pattern Timeframe

Bear Flags can form in any timeframe but occur more frequently in hourly and daily charts. Flags happen quickly and usually last no longer than three weeks.

Identifying a Winning High-Tight Bull Flag

As mentioned, the only accurate flag pattern is a high-tight flag. This bull flag is where the flag pole moves nearly vertically, indicating buyers are willing to bid up the stock even if it’s at very high levels.

The flag is tight, meaning there is a close-fought battle between buyers and sellers over a period of days. Finally, the buying pressure is so strong that the price breaks upwards, and an explosive rally averaging +39% ensues.

One Bull Flag Pattern Succeeds 85%, The Rest Fail

What Happens After a Bear Flag Pattern?

Two decades of research by Tom Bulkowski show that after a bear flag pattern is confirmed on a price breakdown, there is a 45% chance of a successful trade averaging 9%. These are very poor probabilities.

What Happens with a Failed Bear Flag Pattern?

A bear flag in a bull market fails 55% of the time. When a bear flag pattern fails, the stock price fails to achieve the price target or reverses before reaching the height of the flag pole. At this point, it makes sense to discard the pattern.

How to Automatically Identify Bull & Bear Flags?
