Base(redirected from plastic base)
Also found in: Dictionary, Thesaurus, Medical, Legal, Encyclopedia.
In technical analysis, a situation in which the support level and the resistance level are roughly the same for a given (usually long) period of time. That is, a base occurs when a security trades only in a very narrow range. A base indicates that the supply and demand for a security are at an equilibrium. This means that the security is unlikely to be bullish or bearish in the near future.
