I'm new to StockFetcher but want to get a new filter rolling. I searched the Forums but can't find an exact match.

Here's what I'm looking for:

# days down (user defined)
Based on stock matching the above, what has been historical data that shows a stock will rebound the next day?
Output a % of up day chance
Output a % gain on that specific up day.
Output only results that achieve higher % than user defined

Run the filter and get the following:
For example, Stock "A" has been down 3 (user defined) consecutive days.
- Output - It has happened 12 times in the past "user defined period".
- Output - Out of those 12 times, 75% (8 of 12) of the time it goes up the next day
- Output - Out of those 8 days, it goes up an average of 4.2%
- Output - Only show stocks that rebound more than 3.2% (user defined)

1. To make it easier on any of us to help you it would be nice if you could post your working filter or the filter your search turned up that was closest to what you envision.

2. I have a few questions regarding your "Run the filter and get the following:" section

a. In this line

- Output - It has happened 12 times in the past "user defined period".

is the '12' user defined or is it just the past "user defined period" that is user defined?

I believe the most days in the past that SF will allow a filter to capture statistics from is 252 at a time, then you have to use a date offset to move it back a year and you can search back another 252 days from then...

b. in the following line:

"- Output - Out of those 12 times, 75% (8 of 12) of the time it goes up the next day"

Did you mean to get 66.6...% or 9 of 12?

c. Do you realize that some of the Output statistics you want will have to be shown/duplicated on every output line when the filter results contain more than 1 stock?

Thanks,
Ed S.

Ed,

Thanks for the response.

Answer to number 1 is that I'm new to this and I'm not even educated enough at this point to create a filter.

Regarding a number 2,
a- It has happened "x" times in the past "user defined period". "user defined period" is a block of time, day/week/month
b- Sorry, yes, I meant 66.6%, not 75%. Long day.
c- No I didn't realize that and honestly I'm not sure how to respond to that. I was hoping the data blocks I mentioned as outputs would be displayed above the graph of each result. (ie volume, share price, etc)

Thanks Ed for your help. What can I say, I'm green at this. Is this request is out of the ordinary?

Your request isn't much different from many others, just some parts of it may be more difficult to do than the average filter so I was just hoping for a starting point since I was unclear about some of items you seemed to want.

As far as how the final display might look for your filter; based on your response you must have the results page set on Chart, as opposed to what I normally have it set on which is Table; so you actually will see numbers above each stock's result chart.

Thanks,
Ed S.

Try the below filter out and see if it meets your needs and let me know.
For testing purposes I limited the stocks results to those > $2,000 and the historical look back period to 75 days.
