What is happening in the market
During an uptrend, deep selling emerges, even if the close recovers; It is a warning of fragility.
Where it matters

Back closure under the body or minimal, preferably with greater volume.
When it is invalidated
New firm close on the pattern's high.
Common mistake
Consider it confirmed bearish without waiting for the next session.
