Existing Downtrend
To be considered a bullish reversal, there should be an existing downtrend to reverse. A bullish engulfing at new highs can hardly be considered a bullish reversal pattern. Such formations would indicate continued buying pressure and could be considered a continuation pattern. In the Ciena example below, the pattern in the red oval looks like a bullish engulfing, but formed near resistance after about a 30 point advance. The pattern does show strength, but is more likely a continuation at this point than a reversal pattern.
