# Crab Pattern

Harmonic Patterns Explained

## What is the Crab harmonic pattern?

The pattern was discovered in 2001. Just as it is with other harmonic patterns, this pattern is a reversal pattern. Therefore, we have the bearish crab pattern that indicates a bearish reversal in price and a bullish crab pattern that indicates a bullish reversal in price. Just as it is with other patterns, there’s a naming convention for every leg in the formation.

Key takeaways:

• The Crab harmonic pattern is a reversal pattern
• The Crab harmonic pattern is a 4 legged pattern
• The crab pattern follows strict Fibonacci ratios

Beginning with the swing low or high, every leg is marked by a letter. There are five swing points named as X, A, B, C and D. In some patterns, you will only find four (X, A, B and C).

The crab pattern is different because of its sharp movement in the CD leg. This is usually a 1.618 percent Fibonacci retracement of the XA leg, the previous part of the crab pattern.

Some rules that have to be followed to confirm a crab pattern, such as:

• Following the XA leg in price, the point B is a retracement of between 38.2 to 61.8 percent. This retracement should ideally be lower than 61.8 percent
• The AB leg, is a counter trend move to the initial leg
• After point B, the next leg, BC, can run up to 38.2 to 88.6 percent Fibonacci ratios of the AB leg (C should never go beyond point A)
• Following the BC leg, price reverses once again, with the CD leg being the longest and reversing between 161.8 percent of the XA leg and an extreme 224.0 to 361.8 percent extension of the BC leg

## When a Crab harmonic pattern is confirmed

After the crab pattern confirms these factors, a position can be taken after the CD leg is made. Even though you will not notice the CD leg is always reversing close to 161.8 percent, if price action starts to stall and such a reversal begins to happen, it can be a high probability trade setup.

It is always better to wait until point D is made and then take an appropriate short or long position. Stop-losses are placed at the low or the high of D, and targets are typically points A or B in the pattern.

## How to identify the Crab pattern?

It can be hard to be familiar with the Fibonacci retracement and extension values in a crab pattern. Also, it can become tiring when using the Fibonacci tool to measure each leg while drawing the crab pattern.

Aside from the main rules of the crab pattern, traders can look for the following signs in the market, by analyzing the lows and highs and simply observing the price movement.

• BC leg mostly exists within the XA leg
• C is a higher low as opposed to A in a bearish crab pattern or C is the lower high as opposed to A in a bullish crab pattern
• B makes a lower high when compared to X in a bearish crab pattern, or B makes a higher low when compared to X in a bullish crab pattern
• D is the extreme, indicating a lower low or a higher high, going beyond X

## What does the Crab harmonic pattern tell traders?

Just like the butterfly, it can help traders identify when a current price move is likely getting to its end. This means traders can enter the market just as the price changes direction in the opposite way.

The crab and deep crab represent important overbought and oversold conditions, and reaction after completion is mostly sharp and fast. It is the opinion of many analysts and traders that the crab pattern and deep crab represent some of the quickest and most profitable patterns out of all harmonic patterns.

## Trading a bearish Crab pattern

To trade a bearish crab pattern, put a short (sell) order at point D (the 161.8 percent Fibonacci extension of the XA leg).

• Entry: Identify where the pattern will end at point D, and place your order
• Stop-Loss: Put your stop-loss just below point D
• Take Profit: The location of your profit target is highly subjective and depends on your objectives and market conditions. If you desire aggressive profit, place it at point A of the pattern. For a more conservative profit, place it at point B.

## Trading a bullish Crab pattern

First of all, choose the crab pattern charting tool and follow all the above rules to identify the pattern. Remember that the Fibonacci ratios are very important to trade the crab pattern. If you notice the pattern on a price chart and if you find the ratios not matching with the pattern rules, it means that the pattern is not valid. So do not trade that pattern.

When the price action confirms the pattern, immediately enter for a buy. If you are a conservative trader, ensure you wait for a couple of bullish confirmation candles before entering the trade.

There are four targets (X, B, C, A) to place the take-profit order in the crab pattern. At the start, traders try to book full profit at point A, but when the price crosses point B, the market turns sideways. So book half of your profit at point B and then close your full positions at point A.

Most of the traders placing their stop-loss way below point D; however, that’s a wrong way to do it because they are risking more due to this simple logic. If the price action breaks point D, it automatically invalidates the pattern.

## Crab pattern vs. Butterfly pattern

The two main things that differentiate the crab pattern from the butterfly pattern is that a butterfly pattern has a swing point D that ends at the 127.2 percent Fibonacci extension of the XA leg. Also, the butterfly pattern retraces to 78.6 percent of the previous XA leg.

But when you consider the crab pattern, the swing point D ends at the 161.8 percent extension of the XA leg and terminates the AB leg between 38.2 percent and 61.8 percent. These two major differences in the Fibonacci ratios between the crab pattern and the butterfly pattern make them unique from each other.
