If price were to break above or below the S/R (Support/Resistance), the S/R would then reverse its role. A break above resistance changes the resistance to support, and a break below support changes the support to resistance. This is also called a change in polarity.

When I say "break above or below", I mean the current candle of the timeframe being viewed, actually closes above or below the S/R. When this does occur (a breakout), price often will go back up or down to the former S/R and hit or get close to it. This is referred to as testing the area.
