Dark Cloud - I've just recently began studying these JC patterns.. However, I did find this on Bulkowski's site:
The best setup for the dark cloud cover candlestick is for it to appear when price is trending lower. An upward retrace of that down move appears followed by dark cloud cover. It signals a reversal and when price breaks out downward, and the stock joins the downward primary trend already in existence.
Theoretical performance: Bearish reversal
Tested performance: Bearish reversal 60% of the time
Frequency rank: 46
Overall performance rank: 22
Best percentage meeting price target: 62% (bear market, down breakout)
Best average move in 10 days: 5.36% (bear market, up breakout)
Best 10-day performance rank: 19 (bull market, up breakout)
I can't say this week has been trending lower - nor have we been in a down move here. Let's pray the Dark Cloud on this stock is going to fall into the 40% of these rankings and not the 60%.
