<SPAN
class=868032513-30062003>Interesting... Have you considered including a volume
component to help measure the strength? Often an upward (or downward) trend on
increasingly lower volume signals trouble, or at least a pause, on the
horizon.
Regards,
Jayson

Re: proof of an uptrendI have been working on some
ideas for defining a trend for use asconfirmation for entry signals. I am
still working on it, but thought Imight add it here to see what others think
of it. This is one way I amtrying, and is one of the 2 ways so far more
successful than others.Basically it is an indicator so far, and trend
signified by the position ofthe 2 lines, green above red is rising, red
above green is falling.As I said it is early days for this as
yet//INDICATOR C 2//Trending//by Graham Kavanagh 09 June

proof of an uptrendRon- If you're going to use slopes, think of them
as positive or negative.Don't try to order them because they depend on scale
and you'll getincoherent rankings.Depending on how you ultimately
decide to define a trend and your timeframe,you may also want to take an
actuarial approach to look at how long trendslast. Of course there are
no certainties, only probabilities.Mark--- In

finally able to actually create some scans that work. Now Iwant to add
something to my buy scans that will insure that the stocks thatreceive a buy

it's linear regression must be in an uptrend. I wouldappreciate any
and all suggestions regarding what criteria that I should putinto my buy
scans that would insure that the stock is truly in an uptrend, in
order for it to be eligible to receive a buyarrow. Regardless of
the other suggestions that may be forthcoming, I still want to test the
concept of positive linear regression. I have copied the information
from HELP that I think is most relevant to whatI want to do. I
am a little puzzled regarding what these HELP comments are really
saying. All that I am really looking for in thispost is the statements
that I need to add to my buy scans thatwill insure that the stock is truly
in an uptrend. Any and allcomments will be appreciated.
