Related to flagging down: flagging off
In technical analysis, a situation on a chart in which a security's price undergoes a steep rise or fall, then trades within a narrow price range. When a steep rise proceeds the narrow trading, it looks somewhat like a flag raised on a pole. Many analysts believe that when a flag occurs, the narrow trading is only temporary and will soon be followed by another steep rise or fall. That is, a rise will follow a rise and a fall will follow a fall.
