Definition from Price action by Buffy:
Outside Bar, also called a Wide Range or Engulfing Bar, is a bar with a high that is higher than the previous bar and with a low that is lower than the previous bar thereby engulfing the previous bar. Since the open and close are close together on the marked bar, neither the buyers or the sellers are in control and the market is undecided which way to go.
When the open is in the bottom quarter/third of the bar and the close is in the top quarter/third of the bar, it is said to be bullish engulfing with the buyers in control. When the open is in the top quarter/third of the bar and the close is in the bottom quarter/third, it is said to be bearish engulfing with the sellers in control.
Another definition used for this bar – especially if candlestick charts are used - is that the open and close have to engulf the previous bars open and close and not just the high and low of the bar. With this definition, the wide range bar or engulfing bar does not need to have a higher high or lower low to qualify. The first definition most probably came about with bar charts where it is harder to notice the open and close.
