Coarse Filter Logging

Hi Justin E 

I managed to print the activeUniverse in the attached algo.  I think that is what you are after.  I don't understand though why the universe changes.  I thought the universe is set at the start of the algo in the initialize and then not called again.  This universe though seems to update every two months? The algo comes from ‘Part time Larry’s'  youtube video shown below and I copied his code from and modified it slightly.

 at about minute 25, explains more on your problem.  

Ok, so I see the dynamic universe updates daily or all the time.  

Hey Justin E,

there are just 3 things I would change to make it work.

line 4: c.Symbol → c
line 8: [10] → [:10]
line 11: return [c.Symbol for c in self.filteredByPrice]

here's the working code:

def CoarseSelectionFilter(self, coarse):

        sortedByDollarVolume = sorted(coarse, key=lambda c: c.DollarVolume, reverse=True)
        symbols_by_price = [c for c in sortedByDollarVolume if c.Price > 1 and c.Price < 5 and c.HasFundamentalData and c.Volume > 50000 and len(c.Symbol.Value) <= 4]
        self.filteredByPrice = symbols_by_price[:10]

        
        for c in symbols_by_price[:10]: 
	        self.Log(",Symbol," + str(c.Symbol.Value) + ",DollarVolume," + str(c.DollarVolume) +  ",Price," + str(c.Price) + ",Volume," + str(c.Volume))

        return [c.Symbol for c in self.filteredByPrice]

Hope it helps ;)

Thank you Newoptionz  and Nico Xenox!

Nico, your suggestions made it work, I also realized from Newoptionz video post that I need c and not c.Symbol.
