Does anyone know how to write a filter such as: "show stocks where ema(10) has turned up in the past 1 day and close price is between 1 and 10 and average daily volume(90) is above 100000". I don't know if there is wording for "has turned up"....I can't get one to work.
Thanks, Frank

Hi Frank,

I suggest

Does anyone know how to write a filter such as:

> I don't know if there is wording for "has turned up"....I can't get one to work.

There are many ways to write a filter, any filter; here I've written one that is simple; the simpler the better. I'd assumed here that instead of saying ""EMA(10) has turned up" -- you wanted to say something more specific, like, "I don't care what the EMA(10) did before yesterday, but I do care about this: today's EMA(10) should be higher than that of yesterday.

So here is your filter, and this one works...
Fetcher[Show stocks where
close is between 1 and 10
and average volume(90) is above 100000
and EMA(10) is above EMA(10) 1 day ago
]



Alternatively, if we want to be more demanding, we can add a few more restrictions, and say,
Fetcher[Show stocks where
close is between 1 and 10
and average volume(90) is above 100000
and EMA(10) is above EMA(10) 1 day ago
and EMA(10) 3 days ago is above EMA(10) 2 days ago
and EMA(10) 4 days ago is above EMA(10) 3 days ago
and EMA(10) 5 days ago is above EMA(10) 4 days ago
and EMA(10) 6 days ago is above EMA(10) 5 day ago
]


It's really up to you.

I hope this helps.

Rob

P.S.: If we want to make the 2nd filter more perfect, we should add, "and EMA(10) 2 days ago is above EMA(10) 1 days ago"

P.P.S.: If we want the curling more pronounced, we can add (without the quotes),

"and EMA(10) divided by EMA(10) 1 day ago is greater than 1.01",

but then, as you see, the more restrictions we add, the fewer stocks we will have.

I hope this helps.

I believe another way to say "has turned up in the past 1 day" is "slope crossed above 0" meaning it was less than zero yesterday and today it has turned up.

Fetcher[
slope of ema(10) crossed above 0

AND volume(90) is above 100000
AND price between 1.00 and 10.00
AND add column slope of ema(10)
AND add column slope of ema(10) 1 day ago
]



You can try playing setting a min amount of turn up to reduce the result set more. Another thing you might try if you want more results is find stocks where the slope crossed above 0 in the past n days.

To Rob: Thanks for the help/advice. My intention was to try and catch a stock as its EMA(10) began to turn up and approached its EMA(25). Whether that was/is a very good idea is to be determined yet, I guess.

Try:
Fetcher[show stocks where ema(10) is converging towards ema(25) for 1 day]
