What is swing high/swing low

Can some one explain to me what swing high and swing low means that would be very helpfull

Here’s a pretty good explanation

Trading with Swing Highs and Swing Lows

The link Talon gave has a great description, but here is a picture with more “real word” examples.

I took this screenshot months ago to illustrate a different point, but it has a lot (not all) of the swing highs/lows circled. It helps to see how these points come together to make a trendline.
