# Gartley Harmonic Pattern "Crab"

The topic of today's lecture will be a harmonic Gartley pattern, which is quite rare in the market - the "Crab" pattern. Harmonic pattern "Crab" was discovered relatively recently, in 2000, but has managed to win particular popularity among the adherents of harmonic analysis.

## Description of the harmonic pattern "Crab"

Comparing it to with the "Butterfly Pasavento" harmonic pattern, we can determine the main difference - a relatively small amplitude of the segment AB, which in the "Crab" should not be more than 61.8% of the HA beam height. The best option would be a value in the region of 38.2% or 50%.

The main and obligatory condition for the formation of a harmonic pattern "Crab" is the height of point D - it must be at the level of 161.8% of the HA movement. Fibo parameters of other tops are standard floating:

• top C should be in the range 38.2% - 88.6% from the AB motion;
• The working range of the top B will be the levels 38.2% - 61.8% from the movement of the HA;
• except for the obligatory condition of the location of the top D relative to the movement XA, this point must be depending on the movement from BC at levels such as 224%, 261.8%, 361.8%, 423.6% Fibonacci.

## A practical example of the "Crab" pattern

Figure 2 shows a market example Bears of the harmonic pattern "Crab". As we can see, this model confidently starts to work out right after reaching the obligatory level for the top D - 161.8% of the XA movement.

It is not uncommon to see "Crab" pattern models in the market with the top D ending higher than 161.8%. Such a harmonic pattern is called the "Deep Sea Crab". Usually, in such pattern the top B is formed above the level of 50% from the movement of the KA.

Including the signals of the harmonic pattern "Crab" in the calculation of entry points, you can get a great addition to your trading system.
