Bullish and Bearish Alternate Bat Patterns
• Bullish alternate bat patterns are fundamentally composed of three peaks and two troughs. The second trough being higher than the first trough and the second peak being lower than the first, with the third peak being higher than both the first and second peaks.
• Bearish alternate bat patterns are fundamentally composed of three troughs and two peaks. The second peak being lower than the first peak and the second trough being higher than the first, with the third trough being lower than both the first and second troughs.
The ratio measurements recommended by Scott Carney, who originated the pattern, are as follows:
• Wave 1 of the pattern, generally referred to as XA, has no specific ratio requirements.
• Wave 2 of the pattern, generally referred to as AB, should retrace to 38.2% of the range set by wave 1.
• Wave 3 of the pattern, generally referred to as BC, should retrace by at least 38.2%, but no further than 88.6% of the range set by wave 2.
• Wave 4 of the pattern, generally referred to as CD, should extend to at least 200%, but no further than 361.8% of the range set by wave 3.
• The last measure, generally referred to as AD, is that of wave 4 as a ratio of the range set by wave 1, which should extend to 113%.
