Bearish Engulfing Sell Signal
Three methodologies for selling using the Bearish Engulfing Pattern are listed below in order of most aggressive to most conservative:
Sell at the close of Day 2. An even stronger indication to sell is given when there is a substantial increase in volume that accompanies the large move downward in price (see: Volume).
Sell on the day after the Bearish Engulfing Pattern occurs; by waiting until the next day to sell, a trader is making sure that the bearish reversal pattern is for real and was not just a one day occurance. In the chart above of Verizon, a trader would probably entered on the day after the Bearish Engulfing Pattern because the selling continued.
Usually trader's wait for other signals, such as a price break below the upward support line (see: Support & Resistance), before entering a sell order. However, in the case of Verizon above, the Bearish Engulfing Pattern occured at the same time as the trendline break below support.
