Dimitris,
actually itīs not. Exrem and Valuewhen judge the occurence from the back
ofthe chart while I try to find the first occurrence of a condition right
after another condition has taken place.
Example: I want to detect the first instance of b right after a has
happened:
a a a b b b
Using Valuewhen I would have to use Valuewhen(..,..,3). But I donīt know in
advance how many occurrences of b take place. So I thought the only way to
address this b is to find the first right AFTER the occurrence of a.
Do you know what I mean???
Thanks
Markus

Subject: [amibroker] Re: Sequence of two conditions
For
cond1=a;
cond2=b;
you may have a sequence
a, a, b, b, b, a
with
cond11=exrem(cond1,cond2);
cond22=exrem(cond2,cond1);
you will have
a, b, , a
ie only the forst occurrence of each a or b.
Is this what you are looking for ?
