The indicator displays a sloping trend line. Its parameters are set when the indicator is launched by a trader. The trend line defines the signal trigger level. The line breakthrough activates signals accompanied by emails and push notifications.
During the first launch, the line that sets the trigger level is colored gray and remains inactive.

The indicator provides signals at each tick, during which the line remains broken till the signal limit is reached.

After that, the trigger line is colored gray and becomes inactive until moved to required levels by a trader with the corresponding color change.
