You'll often hear analysts talking about a certain security approaching a resistance or support. These are simply price levels or a range of prices that a security or currency doesn't often go over resistance or go under support. You can see in the chart the support is the level at which the price seldom falls below and the resistance is the level the price seldom exceeds. At support levels the number of buyers generally exceeds the number of sellers and pushes the price back up, and at resistance levels the number of sellers exceeds the number of buyers causing the price to go back down.
Once a resistance or support level is breached, the roles of the resistance and support flip. If the price surges below a support level, that same support level will then become the new resistance level. Conversely, if the price surges above a resistance level, that same resistance will tend to become the new support level. This role reversal will generally only occur once a strong price moved has shifted the price to a new range - often caused by major news or economic reports.
As an example take a look at Figure 2. Initially, the dotted line represented a resistance level, but once the price broke through the resistance into a new range, the old resistance level became the new support level. Again, once the price broke below the dotted trendline the level reverted to acting as a level of resistance. Support and Resistance Reversals.

Or alternatively if the trader identifies a support level the price seldom falls below, he could use that information to help him decide on an entry point to his position.
