entry indicator

[Rui Marques <np93je@xxxxxxxxxxxxxxx>]

I didnt elaborate on this (no time), but had one idea. Why not use the
precise condition that defines the entry to get the entry indicator? Example:

Entry = c > mov(c,20,s)
indicator = alert (C>mov(c,20,s), _number_of_desired_days_)

Does it work?
