Filter=1??

["IVA GmbH" <funnybiz@xxxx>]

Folks,
 
I still have a little trouble to use the "prpoer" 
settings in exploration mode:
 
1./ If I set filter to "filter=1", are then all 
quotes AND all stocks being investigated?
2./ If I use above setting and the range is still 
set to "n=1", how many stocks are being actually investigated and for howmany 
quotes?
3./ If I want all stocks being investigated for the 
first time a desired condition might be true, is the following correct, in case 
I would like to have the low to be displayed:
 
Filter=Valuewhen(condition,low,1);
 
Addcolumn(low," last low",2.2)
 
Or would I have to ask for 
Valuewhen(condition,low,1)==1, i.e. the condition to be true(isnīt the truth of 
this condition already being checked in the Valuewhen statement ITSELF)?? 
??????
 
Thanks for clarifying this!!!!!!!
