Here's a video on how to identify Harmonic Crab Patterns. This runs through the pattern recognition process, trade setup and trade management for all conventional Harmonic Crab Patterns. OTSoftware identifies all Advanced and Harmonic Patterns automatically and objectively.It also enables you to create up to three of your own patterns. This has changed my trading success dramatically and maximised profitability.

Once the X and A points have been identified the market forms the B by fulfilling at least a 38.2% retracement and then either precise 38.2%, precise 50% or precise 61.8% retracement of the XA leg. The term "precise" means that it is closer to one Fibonacci level than the other. For example, if the retracement is 1 pip less than 44.1% (halfway between 38.2% & 50%) then it is treated as 38.2%, if it is 1 pip more than 44.1% then it is treated as 50%.

To summarise, the B point is valid if it lies between 38.2% and 1 pip less than 70.2% XA (halfway between 61.8% & 78.6%). The importance of whether or not the B point is a "precise" 38.2% , 50% or 61.8% is to do with the formation of the D point, also known as the Potential Reversal Zone (PRZ). This is explained in more detail below.

The C point is valid if it touches at least a 38.2% retracement of the AB and it does not exceed the A point (100% AB).

If the B point has formed at the "precise" 38.2% of the XA, then the Potential Reversal Zone (PRZ) is calculated as a combination of the **161.8% extension of the XA **level, 2**.618AB=CD** movement level (so the same distance as the 261.8% of the A-B leg but this should be copied across and measured from the C point) and finally, the corresponding BC extensions:

**361.8% of the BC if the C-point is precise 38.2% of the AB, **

**361.8% of the BC if the C-point is precise 50%% of the AB, **

**361.8% of the BC if the C-point is precise 61.8% of the AB, **

**361.8% of the BC if the C-point is precise 70.7% of the AB, **

**314.0% of the BC if the C-point is precise 78.6% of the AB, **

**314.0% of the BC if the C-point is precise 88.6% of the AB. **

If the B point has formed at the "precise" 50% of the XA then the Potential Reversal Zone (PRZ) is calculated as the **161.8% of the XA** level, 2.24**AB=CD** movement level (again, measuring 224.0% of the A-B leg and use this measurement as a length/number of pips to travel from the C point) and finally, the corresponding BC extensions:

**361.8% of the BC if the C-point is precise 38.2% of the AB, **

**361.8% of the BC if the C-point is precise 50%% of the AB, **

**361.8% of the BC if the C-point is precise 61.8% of the AB, **

**314.0% of the BC if the C-point is precise 70.7% of the AB, **

**314.0% of the BC if the C-point is precise 78.6% of the AB, **

**261.8% of the BC if the C-point is precise 88.6% of the AB. **

If the B point has formed at the "precise" 61.8% of the XA then the Potential Reversal Zone (PRZ) is calculated as the **161.8% of the XA** level, 1.618**AB=CD** movement level (again, measuring 161.8% of the A-B leg and use this measurement as a length/number of pips to travel from the C point) and finally, the corresponding BC extensions:

**361.8% of the BC if the C-point is precise 38.2% of the AB, **

**361.8% of the BC if the C-point is precise 50%% of the AB, **

**314.0% of the BC if the C-point is precise 61.8% of the AB, **

**314.0% of the BC if the C-point is precise 70.7% of the AB, **

**261.8% of the BC if the C-point is precise 78.6% of the AB, **

**224.0% of the BC if the C-point is precise 88.6% of the AB. **

**Harmonic Crab Target 1**: 38.2% retracement of the AD leg.

**Harmonic Crab Target 2**: 61.8% retracement of the AD leg.

**Harmonic Crab Stops**: 213% extension of the XA.
