                 You might be able to do a date check: If date is greater than 20110101, then 0 else your  formula. Do a search on this forum for date for syntax.

                Hi, try this: Code:
expiredate:=20110120; {means: year: 2011 , month: 01, day: 20 }
today:=LastValue(DayOfMonth())+100*LastValue(Month())+10000*LastValue(Year());
{example signal - here you should enter your signal formula}
signal:=(Mov(C, 5, S)>Mov(C, 20, S)) - (Mov(C, 5, S)<Mov(C, 20, S)); 
{shows signal only if date is not expired}
If(today<expiredate,signal,0);
