I have read again and again to watch volume (and price) around 10am is to see if the stock is performing as expected, but how does one judge volume is up? It's obvious it volume is above the average at that time, but what if it's a fraction (say less than 33%) of average volume? Are there any guidelines on this concept say if volume is > 25% aver vol then it's up?

Through trial and error, this is the screen I run at 10am.
Looking for both volume and price spikes.

Fetcher[
set{vv,volume 1 day ago divided by 1.1}
set{pp,price 1 day ago * 1.3}
price is greater then pp
and price is greater then price 1 day ago
and volume is greater then vv
and price is between 1 and 80
and volume is greater then 5000

You have

set{pp,price 1 day ago * 1.3}
price is greater then pp
and price is greater then price 1 day ago

If pp is "price 1 day ago * 1.3"

then if "price is greater then pp " is TRUE

then by definition "price is greater then price 1 day ago" has to be TRUE and thus redundant.

Is there a mistake of some kind?

HTH.

Hmmm ...

well, looking at this, I am in total agreement with you....

so I deleted "and price is greater then price 1 day ago"

...and the screen went from returning 1234 stocks to 1604 ???
(run at after market close 01/03/2007)

How can this be ?

A look at the results and all the stocks that have a negative return (%Chg)
were filtered out (using the original screen) .......

Fetcher[
set{close1ago, close 1 day ago }
set{ppx, 1.3 * close1ago }

add column ppx
add column close1ago

and close1ago equal 1
]



This filter should have PPX = 1.30

There's a bug UNLESS I am missing something!!

2 minutes later....

NO BUG and here is why...

PP is the pivot point reserved word!!

When I changed PP to PPX the problem went away so...

Lockwhiz, here's your filter...

Fetcher[
set{vv,volume 1 day ago divided by 1.1}
set{ppx,price 1 day ago * 1.3}
price is greater then ppx
and volume is greater then vv
and price is between 1 and 80
and volume is greater then 5000
]




HTH.

WOW ... Thanks !
TRO .... The CSI of StockFetcher !
I am in awe.

Now to see why it was giving me some decent stocks....giving me the performance
that I had intended..... It obviously is not coded correctly... but ...like
that old adage "If it works, don't fix it".... says it all.

Like I had said, alot of trial and error started giving me the results that I
was looking for.... Try it and see ....10:00am ! (so with the 20 minute delay,
its actually looking at 10 mins into the trading day)... and now, knowing what
it is actually doing, maybe it can be fine tuned....lets see !

I had developed this when Muddy spoke of the streaming HOD ... with this idea,
and including VOLUME, I figured thats the way to get SF to give me a similar
"window of opportunity".

Thanks again !

... the one line of the filter that is meaningless
is the "set{pp,price 1 day ago * 1.3}" ... I modified my
origianl screen, so it will use
Pivot Point as the measure to base the screen on.... and it
does give me the "window of opportunity". But the intent, and the
original post was truly missed.


MODIFIED ORIGINAL
Fetcher[set{vv,volume 1 day ago divided by 1.1}
set{pp,price 1 day ago * 1.3}
price is greater then pp
and price is greater then price 1 day ago
and volume is greater then vv
and price is between 1 and 80
and volume is greater then 5000
]



I am going to re-focus on building a screen that works
with the opening trends ... ie price spike on volume. The price
, set{pp,price 1 day ago * 1.3} seems to be a good fit. Volume
I would expect to be more in the order of 10% - 15 % of yesterdays
total volume.

Lockwhiz

PP is used by StockFetcher for the Pivot Point.

Your SET statement DOES NOT CHANGE the value of PP!!



Fetcher[set{vv,volume 1 day ago divided by 1.1}
set{Xpp,price 1 day ago * 1.3}

price is greater then pp

and price is greater then price 1 day ago
and volume is greater then vv
and price is between 1 and 80
and volume is greater then 5000

ADD COLUMN XPP
ADD COLUMN PP
ADD COLUMN VV

]



Take a look.

HTH.

Thanks for the updated version ... I like it !
