I can't find an exact definion of these terms. When I googled them I found a couple of definition, and I don't which of them are reliable.

In
http://www.investopedia.com/terms/b/...engulfingp.asp
there is no mention to open/close requirements

In this one
http://www.dailyforexjournal.com/pos...side-bars.html
there are precise open and close requirements

What is the right one?

A bullish Outside bar is a bullish bar (i.e a bar with a close higher than it's open) that has a range (space between it's high and low) exceeding the range of the previous bar.

The open and close need not necessarily be beyond the range of the previous bar, but if they are, the bullish outside bar is considered to be stronger.

Same goes with a bearish outside bar.
