 Hi,
 Im a novice at this so my question might be kind of simple but does anyone
 know how to apply the HP-filter in gretl to alot of time series. I have like
 200 series to filter so doing it manually is pretty time consuming... 
Loops are your friends; try this in the console or, better still, in a script:
loop foreach i x y z
  series cyc_$i = hpfilt($i)
  series tre_$i = $i - cyc_$i
end loop
 Thanks!
 
You're welcome!
