Being blocked twice at the same place is a signal
• Double top: the high is attempted twice and not exceeded, and the low in between (the neckline) breaks downward — a candidate for a reversal of an uptrend
• Double bottom: the low is defended twice and the high in between breaks upward — a candidate for a reversal of a downtrend
• The completion criterion is a neckline break. Up to the second high or low it is a possibility, not a pattern
Connection to our data
• Whether volume on the second attempt was lower than on the first is the key point to check — a weakened retry leads to a reversal
Where people slip
• They presume a top or bottom before the neckline is confirmed and enter the opposite way
Skill lies not in memorizing pattern names but in waiting for the completion conditions (neckline + volume).
Have you ever entered by presuming a reversal before confirming a neckline break?
