I tried to look for "backup" in other glossaries, but i could not find it so far.
Since it says"See: Trendline", I thought it might be helpful to quote it.
Please see:
Trendline
A chart used by technical analysts. A line is drawn by connecting the highest or lowest prices to which a security has risen or fallen within a period. The line's angle shows whether the security is in a downtrend or an uptrend. If the security's price rises above a downward sloping line or drops below a rising uptrend line, analysts believe the security will start to move in a new direction.
