This could be a 5-0 Pattern and here is the definition:
The Bullish 5-0 starts at the 0 point, representing an extended down leg to begin the pattern at X. The initial point X acts as the low of this prior substantial decline. After a quick reactive bounce to the A point, the structure abruptly continues the decline, only to find support slightly past the prior low at X. This is the failed wave 3 or wave 5 – in Elliot Wave terms – that establishes the rest of the structure. However, the important limits from the Harmonic Trading perspective requires that this X, A extension be at least a 1.13 but not greater than a 1.618. After that impulsive failed wave is established, the BC leg rallies to at least a 1.618 extension of the AB length but it does not exceed 2.24. Again, this tight range of 1.618-2.24 is a defining element of the structure. If the 1.618 limit is not reached, the structure is not a valid 5-0.
After the BC leg has reversed from that zone, the bullish 50% retracement is measured from the B point to the C point. In addition, the Reciprocal AB=CD is projected from the C point (an equivalent length of the AB leg) to compliment the Potential Reversal Zone (PRZ). It will take some time to begin to identify this structure but the obvious characteristic is the failed down wave followed by a precise 1.618-2.24 extension. At that point, it is important to The 5-0 Pattern.
