yes. alert() can be used to pop up a message for some condition.

from from to what? price, close, high, some average, output of a study,... ?
over what time period?

Here is an example of alerting on a percentage over / under.
Change it to meet your needs.

# Percent Change Alert and Label
# @merryday 5/23

# define your percentage amount  (.03 == 3%)
input alertPercent = .03;

# define the two variables in your percentage calculation:
def PercentFrom =  DailyOpen() ;
def CurrentPosition = close ;

# define custom colors for labels
DefineGlobalColor("PercentAbove", color.violet) ;
DefineGlobalColor("PercentBelow", color.dark_orange) ;

def percentChange = CurrentPosition / PercentFrom ;
addlabel(yes,
"Open: " +PercentFrom  +"  Current: " +CurrentPosition ,
if 1-percentChange>alertPercent then GlobalColor("PercentAbove") else
if percentChange-1>alertPercent then GlobalColor("PercentBelow") else color.light_gray
);


addlabel(yes,
if percentChange<1 then asPercent(1-percentChange) +" below Open" else asPercent(percentChange-1) +" above Open",
if 1-percentChange>alertPercent then GlobalColor("PercentAbove") else
if percentChange-1>alertPercent then GlobalColor("PercentBelow") else color.light_gray
);


Alert(1-percentChange>alertPercent, 1-percentChange +" below Open", Alert.Bar, Sound.Bell);
Alert(percentChange-1>alertPercent, percentChange-1 +" above Open", Alert.Bar, Sound.Ding);
