support

definition

A price or price range at which technicians expect the price of a security to bounce one or more times before breaking through to the downside. Support is typically caused by an abundance of buyers and a shortage of sellers at that price level. Technicians believe that the strength of a support area is determined by the significance of the trading that created it. For example a trading range that spanned many months will create more price support than then the trading range for the previous day.
