Please Help for the Query
Hi frds please help me for the below query.What I want to do is to pull out the data from below table :-
date ticker indicator
03/13/2008 3IINFOTECH -8
03/18/2008 3IINFOTECH -4
03/25/2008 3IINFOTECH -5
03/27/2008 3IINFOTECH -3
as such :-
date ticker indicator
03/13/2008 3IINFOTECH -8
03/25/2008 3IINFOTECH -5
03/27/2008 3IINFOTECH -3
Here I want to find the Trend i.e either asc or desc order from the lowest indicator.
In the above sample data -8, -4, -5, -3 out of which I want the asc order data -8, -5, -3 and exclude -4 data.Because the asc order -8, -5, -3 will not follow.
So I want the data
date ticker indicator
03/13/2008 3IINFOTECH -8
03/25/2008 3IINFOTECH -5
03/27/2008 3IINFOTECH -3
