With the exception of the longer upper shadow on the first candle, the 3-black crows look almost textbook to me.
The main pattern I noticed when looking back on the NDX was 3-straight red weeks almost always led to a lower low within 8-weeks. The crow pattern, like you mention, is kind of rare on the COMP and NDX.
We may be wrong to respect this pattern, but with all the calls being purchased at the low, I'm more likely to give it the benefit of the doubt.
