How to Trade a Bearish Crab Harmonic Pattern

If you’re looking to take advantage of one of the most successful trading strategies out there, the bearish harmonic crab pattern is a great way to do it. This pattern relies on the key ratios of Fibonacci numbers to be precise, but you don’t have to know every angle of the pattern in order to explore it successfully. Technology can make the process much easier for those who are relatively new to trading, as there are indicators that can scan for and pick up any opportunities for you. Here, you’ll learn how to best approach trading with the bearish crab harmonic strategy.

What is a Bearish Crab Harmonic pattern?

First, a bearish crab pattern takes a letter W formation.

It’s a bearish reversal pattern.

Meaning price action predicts a fall in prices into future timeframes.

So watch out.

A bearish crab pattern showing after a dominant bullish trend indicates that prices may fall lower in later timeframes.

How Does a Bearish Crab Pattern Form?

A bearish crab pattern forms with five clear swings in prices.

Note that harmonic trading patterns have conventional naming.

So for a bearish crab, the following movements apply:

  1. Prices make a downswing. It marks a bearish impulse from X to A. You can call it the leg XA.
  1. Next, prices bounce from points A to B. 

It’s a retracement of the move XA.

And the prices retrace within limits of 38.2%  and up to 61.8%. 

  1. The third move marks the swing to C.

It marks swing BC. And the leg BC  runs from between 38.2 to 88.6% of the swing leg AB.

One key point is that point C does not hit prices lower than point A.

  1. Prices make a reversal. And mark leg or swing CD.

Swing CD is the longest within a crab pattern formation. It makes a reversal from 161.8% of swing XA.

However, it may make extreme reversals. It may reverse as far as 224.0%  or 361.8% extensions of swing BC.

Once point D forms, it validates the formation of a bearish crab. And appropriate short positions can be taken.

Pro-Tip: The above rules show step by step formation of a bearish crab pattern.

While price action anticipates a price fall from point D, it’s not a 100% guarantee.

Prices can break the anticipation. So, never jump in without a well-set stop-loss position.

In addition, the XABCD pattern tool helps traders check if price swings correspond to a crab pattern. A clear bearish crab pattern must have the extensions and retracements corresponding to the ones above.

How to trade the Bearish Crab Pattern?

Trading a  bearish Crab pattern requires traders to go short or sell.

You sell after locating point D. 

Otherwise known as the order point in harmonic patterns.


You place an order at point D.

Next, set a stop loss above point D.

Take profit position below D.

Usually, there are two ways to approach taking profit positions with the bearish crab pattern.

One is the conservative approach. Where you pick a price not lower than point B in the pattern formation.

With the conservative profit targeting, you expect some good profits in case prices drop to the range of point B.

And second is the aggressive approach to profit-taking with a bearish crab pattern. 

Here, you expect the prices to drop all the way to the price regions of point A. Point A is the first reversal of the first impulse or wave in prices.

Please see the chart above to see how best to set the take-profit positions.  First is the conservative approach at the level marked 3.

And follows the aggressive approach with tale profit at the price level marked with 4

It can be very complicated for beginner traders. 

Bearish crabs and other patterns are usually not easy to spot on price charts.

They require an expert trader to locate. Still, the experts need to know very specific points of entry and exit. And yet, markets have chances of moving against them at times.

Stop hunting is where brokers and market movers ensure prices hit to wipe out stop loss positions. It’s a challenging task for a new trader to know exactly how and where to place a stop-loss position.
