Please go back and look at the history of weekly bullish engulfing candles and reconsider. EVERY SINGLE bullish engulfing candle on the weekly has been followed by exactly six weeks of bullish price action accounting for gains of 34 to 108%, including the previous two weekly engulfing candles. There's still a few days left in this week, of course, and we'll have to see where we end up on Sunday, but for this reason I would not be shorting from here unless it's just a smaller-time-frame scalp/hedge.
