HARMONIC PATTERNS

Fine-Tuning Entries and Stops
Harmonic price patterns take geometric price patterns to the next level by using Fibonacci numbers   to define precise turning points. Unlike other trading methods,   Harmonic trading attempts to predict future movements. This is in vast   contrast to common methods that are reactionary and not predictive.   Let's look at some examples of how harmonic price patterns are used to   trade on the market. (Extensions, clusters, channels   and more! Discover new ways to put the "golden ratio" to work.
Combine Geometry and Fibonacci Numbers 
Harmonic  trading  combines patterns and math into a trading method that is  precise and  based on the premise that patterns repeat themselves. At  the root of the  methodology is the primary ratio, or some derivative of  it (0.618 or  1.618). Complementing ratios include: 0.382, 0.50, 1.41,  2.0, 2.24,  2.618, 3.14 and 3.618. The primary ratio is found in almost  all natural  and environmental structures and events; it is also found  in man-made  structures. Since the pattern repeats throughout nature and  within  society, the ratio is also seen in the financial markets, which  are  affected by the environments and societies in which they trade.  (Don't  make these common errors when working with Fibonacci numbers -  check out Top Fibonacci Retracement Mistakes To Avoid)  By finding patterns of varying lengths and magnitudes, the trader can   then apply Fibonacci ratios to the patterns and try to predict future   movements. The trading method is largely attributed to Scott Carney,   although others have contributed or found patterns and levels that   enhance performance.
Issues with Harmonics 
Harmonic price patterns are extremely precise, requiring the pattern to show movements of a particular magnitude in order for the unfolding of the pattern to provide an accurate reversal point. A trader may often see a pattern that looks like a harmonic pattern, but the Fibonacci levels will not align in the pattern, thus rendering the pattern unreliable in terms of the Harmonic approach. This can be an advantage, as it requires the trader to be patient and wait for ideal set-ups. Harmonic patterns can gauge how long current moves will last, but they can also be used to isolate reversal points. The danger occurs when a trader takes a position in the reversal area and the pattern fails. When this happens, the trader can be caught in a trade where the trend rapidly extends against them. Therefore, as with all trading strategies, risk must be controlled. It is important to note that patterns may exist within other patterns, and it is also possible that non-harmonic patterns may (and likely will) exist within the context of harmonic patterns. These can be used to aid in the effectiveness of the harmonic pattern and enhance entry and exit performance. Several price waves may also exist within a single harmonic wave (for instance a CD wave or AB wave). Prices are constantly gyrating; therefore, it is important to focus on the bigger picture of the time frame being traded. The fractal nature of the markets allows the theory to be applied from the smallest to largest time frames. To use the method, a trader will benefit from a chart platform that allows the trader to plot multiple Fibonacci retracements to measure each wave.

The Visual Patterns and How to Trade Them 
There is quite an assortment of harmonic patterns, although there are four that seem most popular. These are the Gartley, butterfly, bat and crab patterns.

GARTLEY PATTERN 
The Gartley was originally published by H.M. Gartley in his book Profits in the Stock Market and the Fibonacci levels were later added by Scott Carney in his book The Harmonic Trader.

| Figure 1: The Gartley Pattern. | 
 The bullish pattern is often seen early in a trend, and  it is a sign  the corrective waves are ending and an upward move will  ensue at point  D. All patterns may be within the context of a broader  trend or range  and traders must be aware of that (see Elliott Wave Theory).   Point D is a 0.786 correction of the XA wave, and it is a 1.27 or  1.618  extension of the BC wave. The area at D is known as the potential   reversal zone (PRZ). This is where long positions could be entered,   as some price confirmation of reversal is encouraged. A stop is placed   just below the PRZ.

Bearish Gartley 
The bearish gartley pattern formation is similar to head and shoulders pattern, but as you can see the point C is below the point A, hence it is not head and shoulder pattern.  
Formation and trading strategy of Bearish Gartley pattern:
- Point B must retrace 61.8% of AX movement.
- Point C must retrace anywhere from 38.2% to 88.6% of BA movement.
- Point D must be 138.2% or 161.8% extension of the BC movement.
- Point D must retrace 76.8% of AX movement. This is our selling area.
Bullish Gartley
The bullish pattern is as seen below, its formation is quite similar  to inverse head and shoulders pattern, but as you can see below point C  is not on the same level as point A. 
Formation of Bullish Gartley pattern and trading strategy:
- Point B can retrace 61.8% of XA movement.
- Point C can retrace anywhere from 38.2% to 88.6% of AB movement.
- Point D can be 138.2% or 161.8% extension of the CD move.
- Point D can retrace 76.8% of XA movement. Point D is our buying area.
Stop loss in this is always very strict and hence we get very cool risk  reward ratio, many times around 1:5 or more. The very important reason  for trading this pattern is that it is based on uncertain places where  traders are most afraid to take positions, hence giving better meaning for risk.
Butterfly Pattern
|  | 
| Figure 2: The Butterfly Pattern | 
The butterfly pattern is different than the Gartley in that it focuses on finding reversals at new lows (bullish) or new highs (bearish). D is a new low and a potential reversal point if the Fibonacci figures align with the structure. D would need to be an extension of BC in the magnitude of 1.618 or 2.618. This should align with an extension of XA in the magnitude of a 1.27 or 1.618. Entry is taken near D with price confirmation of the reversal encouraged. Stops are placed slightly below the potential reversal area (bullish).
Bat Pattern
|  | 
| Figure 3: The Bat Pattern | 
The bat pattern is similar to Gartley in appearance, but  not in  measurement. Point B has a smaller retracement of XA of 0.382 or  0.50  (less than 0.618), but the extension of the BC wave into D is at  minimum  1.618 and potentially 2.618. Therefore, D will be a 0.886  retracement  of the original XA wave. This is the PRZ: when selling has  stopped and  buying enters the market, enter a long position and take  advantage of  the bullish pattern. Place a stop just below the PRZ.
Crab Pattern
The crab is considered by Carney to be one  of the most  precise of the  patterns, providing reversals in extremely  close  proximity to what the  Fibonacci numbers indicate. This pattern,   similar to the butterfly,  looks to capture a high probability reversal   at a new (recent) low or  high (bullish or bearish respectively). In a   bullish pattern, point B  will                                                          pullback    0.618 or less of XA. The extension of BC into D is quite large, from    2.24 to 3.618. D (the PRZ) is a 1.618 extension of XA. Entries are  made   near D with a stop-loss order just outside the PRZ.
Fine-Tuning Entries and Stops
 Each  pattern  provides a PRZ. This is not an exact level, as two  measurements -  extension or retracement of XA - creates one level at D  and the  extension of BC creates another level at D. This actually makes  D a zone  where reversals are likely. Traders will also notice that BC  can have  differing extension lengths. Therefore, traders must be aware  of how far  a BC extension may go. If all projected levels are within  close  proximity, the trader can enter a position at any area. If the  zone is  spread out, such as on longer-term charts where the levels may  be 50 pips or more apart, it is important to wait to see if the price reaches further extension levels of BC before entering a trade. 
Stops can be placed outside the largest potential extension of BC. In   the crab pattern, for example, this would be 3.618. If the rate   reversed before 3.618 was hit, the stop would be moved to just outside   the closed Fibonacci level to the rate low (bullish pattern) or rate   high (bearish pattern) in the PRZ. 
Figure 5 is an intra-day example of a butterfly pattern from May 3, 2011.

| Figure 5. Bearish Butterfly Pattern - EUR/USD, 15 Minute | 
The price touches almost exactly the 1.618 extension  level of XA at  1.4892 and the extension of BC to 2.618 is very close at  1.4887 (there  are two Fibonacci tools used, one for each wave). This  creates a very  small PRZ, but it may not always be the case. Entry is  taken after the  rate enters the zone and then begins to retreat. The  stop is placed just  outside the most significant level that was not  reached by the rate, in  this case a few pips above the 1.618 XA  extension. Targets can be based  on support levels  within the pattern; therefore, an initial profit target would be just  above point B.
The Bottom Line
Harmonic  trading is a precise and  mathematical way to trade, but it requires  patience, practice and a lot  of study to master the patterns. Movements  that do not align with  proper pattern measurements invalidate a  pattern and can lead traders  astray. The Gartley, butterfly, bat and  crab are the better-known  patterns that traders can watch for. Entries  are made in the potential  reversal zone when price confirmation  indicates a reversal, and stops  are placed outside the nearest  significant (for the pattern) Fibonacci  level that was not hit by the  BC or XA extensions/retracements into the D  (PRZ) area.
